®WARNINGS

AQUATECH WATER JETTING MACHINES

Aquatech water jetting machines are designed to clean sewer pipe, both sanitaryand storm, in an underground environment. These systems operate under highpressure conditions with considerable water ow. Therefore, operators of these

systems must be aware of possible hazards. This is not a complete list of all pos-sible hazards, but represents typical hazards and types of hazards. At all times, theoperator is responsible for the proper use of the machine.

Operators of Aquatech water jetting machines should be aware of the fol-

lowing safety warnings:

• Using this machine for purposes other than cleaning sewer pipe is not recom-mended.

• Always wear required personal protective equipment.

• Water hose that is damaged into the braided lining must be repaired orreplaced.

• Fittings used on sewer hose must be of a type and installed in a manner that

is approved by the hose manufacturer. Only use hose inside of sewer pipe,never use as wash down hose.

• A handgun accessory is provided for the operator’s use when cleaning exter -nal areas of the sewer system. The handgun is designed to shut off automati-cally when the actuator handle is released. Never use a forward jet nozzlethat will not turn off when released.

• Never operate the water system with the relief valves removed, or improperly

adjusted. The main relief valve is set at 2,100 psi. The handgun relief valve isset at 800 psi. Do not operate at pressure readings higher than these unless

the manual specically states that the system has been designed for higherpressures.

• Never walk under raised components such as hydraulically actuated tanks,

doors, etc. Whenever these components are raised, props must be used toprotect workers who must work under them.

• Never operate the machine in a stationary position without rst setting the

brakes, and shifting the rear axle out of the drive line. Always use wheelchocks.

• Never move the vehicle with the boom in a raised or otherwise unsecured

position.

• Always turn off unit power when moving the vehicle.

http://slidepdf.com/reader/full/a-20001057 14/102 PRINCIPLES OF OPERATION 1



®PRINCIPLES OFOPERATIONPOSITIVE DISPLACEMENT EXHAUSTER

AND WATER PUMP UNITS

This machine is a combination vacuum and high pressure water jetting unit for cleaning sewer drains or catch basins.

It also performs other cleaning operations.

The vacuum generator is a rotary lobe, positive displacement exhauster. During operation of the vacuum system, mate-

rial is picked up at the end of the suction line and pneumatically conveyed through the intake tubes, the boom hose, and

through the boom intake valve, to the debris tank. As the material enters the larger area of the debris tank the velocity

of the air ow is reduced and the material drops out of the air stream, settling at the bottom of the tank. The spent air

ows through the ball check valve, and through a metal screen in the centrifugal scrubber externally located at the

front of the body. At this point the ltered air ow enters the exhauster and is expelled through a silencer/mufer to

the atmosphere.

A positive displacement triplex plunger water pump provides the water pressure and water ow to the cleaning nozzle

which propels itself through the sewer line. When retrieving the nozzle under water pressure, material that has built up

in the sewer line is blasted loose and back ushed to the manhole for removal with the vacuum system.

In the water system the water ows from the two water tanks, mounted outboard of the debris tank, through a crossovermanifold, through the water pump feed line, through the suction strainer into the suction side of the pump. The pressur-

ized water is then pumped forward to the water control valve and routed, depending on the position of the valve, either to

the hose reel for cleaning, or by return lines to the water tank. The vacuum and water system can be used simultaneously

when cleaning sewers. This allows conveyance of ushed out materials and water into the debris tank.

This machine is also designed for cleaning catch basins, wet wells, and lift stations where the vacuum operation picks

up the material in the manhole while the water pump supplies water to a lance (part no. 238080) for blasting loose

packed debris and for wetting dry material. Grapple tongs (part no. 234585) are used to remove long sticks and items

that will not t into the pickup tube.

This machine may also be used for leaf pickups. Position the unit at the curb; rotate the boom and extend it to reach all

areas of the tree lawn and sidewalk. The boom is locked in place while picking up leaves to provide maximum operator

safety. To aid in the dumping process of compact leaves, it is recommended that a couple hundred gallons of water be

added to the bottom of the debris tank prior to vacuuming. Unit must be equipped with the liquid ring option (part no.

380924).

CONTROLS AND GAUGES

It is important for the operator to fully familiarize him/herself with the location, appearance and function of the various

controls and gauges on any new Aquatech sewer cleaning machine. Please read this section carefully, and refer to it whenever

any section of the manual describes a control which you cannot identify.

DASHBOARD CONTROLS

Several controls are mounted in the chassis cab itself. These controls allow the operator to engage and disengage the water

pump, exhauster, and hydraulic system. In addition, a main power indicator light and switch, and a low water warning light

and switch are among the standard controls in the chassis cab. The water pump and exhauster are engaged and disengaged

by electro-pneumatic solenoid valves. These solenoids are operated by electric toggle switches in the cab or at the rearoperator station. Because each manufacturer will have a different cab layout, even among models of the same manu-

facturer, our description of their location is general.

UNIT POWER/PTO ENABLE

The unit power switch supplies power to all the other switches. When turning unit off, this switch must be the last one

turned off. Push up to turn on the unit power switch and push down to turn it off. A red light glows inside the switch to

indicate that the unit power is on. The PTO Enable switch also needs to be turned on. Without turning this switch on,

rear control functions will not function. The unit power switch should be turned off when transporting the unit.

®PRINCIPLES OFOPERATION

PENDANT CONTROL

The pendant operates the boom. It lowers and raises the boom, it

telescopes the boom in and out, rotates the boom right and left, andenergizes the boom valve. Each function is controlled by a push

button control. Pressing a button carries out a function, releasing a

button stops a function.

The actuation of the boom is hydraulic, although the pendant performs

electrical functions. Each button makes an electrical solenoid operate

a hydraulic valve. Therefore, the main power switch and the hydraulic

system/PTO must be turned on when operating the boom.

When transporting the unit, the pendant should be stored in the basket,

tool box or cab. Because the control is rugged and can withstand

some abuse, if dropped repeatedly, or run over by the unit, the casewill become cracked or crushed. This may cause some or all of the

functions of the pendant control to cease operation and allow water

to leak inside.

Each operator should spend as much time as necessary to become

completely comfortable with each Function of the pendant control

so that the operation of the boom becomes almost natural.

SIDE OPERATOR’S STATION

There is also an operator’s station at the passenger side of the unit

to allow the operator to control the tank dumping system. It is at thisoperator’s station, as well, that the pendant control is connected.

There is also a unit control box with toggle switches. The box con-

tains a switch for: the throttle, apper valve, boom functions, door

lock/unlock, door open/close and an emergency stop button. The

throttle control at this station allows the operator to control engine

speed, and therefore hydraulic pressure. Operate engine at 1500 rpm

during tank dumping and lock operating functions. Plastic labels at

each control indicate the correct manipulation of the switch for the

function it performs. Consult the labeling to be sure you are operating

the controls correctly. If the labels become unreadable or are inad-

vertently removed, consult the illustration for switch operation. The

hydraulic tank is also at the side operator’s station. A sight glass near

the top of the tank indicates the correct oil level. The oil level must

be above 80 on the sight eye scale. It also contains a thermometer

to measure hydraulic oil temperature. Oil temperature should not

exceed 180 degrees.

AIR PURGE SYSTEM (OPTIONAL)If your unit is equipped with the air purge and cold weather blowout system, you will notice a brass tire valve on the pump. The small brass valve with the knurled cap on the pump head is pro-vided to assist the purge of air trapped inside the discharge section of the water pump. Any trappedair acts as a spring cushion for the compressed water and causes the water to “bounce back”against the cushion of air. This can cause a loud knocking noise from the pump area, and severe pulsating of the sewer hose. This is called “cavitation.” If the air is not expelled, severe damagecan occur in the pump. By twisting the knurled knob in a counterclockwise direction, the valvewill open and allow air trapped inside the pump to be expelled. Water will also be expelled at thesame time. Run the pump at an idle speed for several minutes until all air is expelled, then slowlyincrease pump speed. As the pump develops greater pressure, the water spray from the valve will become very intense. When it is clear that all air has been expelled, close the knurled knob byturning in a clockwise direction and increase pump speed. The knocking sound should disappear,and the pulsating of the hose will be very mild, which is normal for a triplex water pump. At this point it is safe to continue jetting. This procedure is usually only necessary when all water has been previously purged from the system, the suction line strainer has been removed for cleaning, or the pump has been run out of water.

Note: If you have constant problems with cavitation, it is likely that air is being sucked into the pump somehow, orone or more valve springs have broken. If you experience repeated cavitation, even though the pump has not beenrun out of water, you should request an inspection of the water system to determine the cause.

INTERNAL TANK FLUSHING (OPTIONAL)On units so equipped, the control for the internal tank ush is also at the side operator’s station. Thecontrol is the lever on the ball valve at the right side of the water pump plumbing on the pressure sideof the pump. Normally the valve is left in the “reel” position which directs the water ow to the hosereel control on the rear reel. When dumping the debris tank, it is desirable to use the internal tankush system to thoroughly clean the interior of the tank without requiring the operator to manually

wash it down. Do not operate this system while the exhauster system is running, or at speeds inexcess of posted speed and gear range! To operate this system, perform the following steps: 1. The control valve for the Internal Flushing System is located in the high pressure line leaving

the water pump. It is identied by a label: “TANK FLUSH”. In the normal operating position,the valve allows water ow to the rear reel. In tank ush mode, the valve diverts water ow tothe internal tank nozzles in the debris tank, allowing high pressure ushing of the debris tank.

2. Engage the water system from the cab. 3. Open the rear door approximately half way. Follow instructions for dumping the debris tank,

outlined in this manual. 4. To increase the tank ushing capability increase the engine RPM. 5. Adjust the level of the rear door so that the jet spray from the internal nozzles is striking the

middle of the door for maximum cleaning.

6. Operate system until the tank is completely clean or the water supply is depleted.

8/13/2019 A 20001057




®PRINCIPLES OFOPERATIONOPERATING THE COLD WEATHER RECIRCULATION SYSTEM

(OPTIONAL)

Follow the following procedure to operate the cold weather recircula-

tion option (See illustration.)

1. Connect the 1" sewer hose (Item No. 1) from the hose reel

to the female swivel connector (Item No. 3 ) located at the

end of the plumbing beneath the water control valve (Item

No. 4).

2. Turn ball valve handle (Item No. 4) to the “on” position:

straight up and down position.

3. Remove retaining bolt (Item No. 5) on the restrictor valve

handle and turn the ball valve handle (Item No. 6) to the

“on” position: straight in-line with valve.

4. Turn the water control valve (Item No. 2) to the “on” posi-

tion.

5. Turn on unit power and water pump switch in the cab, but

do not disengage rear axle.

6. Unit can now be driven. As unit moves, the water pump will

circulate water throughout the system and back to the tank.

Note: If water recirculation is desired with the truck stationary, disengage the

rear axle through the PTO switch and engage the water pump normally, raise

idle rpm as needed.

Caution: The pump systems should never be operated in a

gear range greater than indicated on either the dashboard

label or “unit identication sheet”. Failure to heed this cautionmay result in severe damage to the water pump or exhauster.

Please consult with the factory if the vehicle gear range is not

specied.

SUGGESTION: Always carry the handgun and

nozzles in the heated cab of the truck when not

in use to prevent freezing.

Note: All units supplied with cold weather recirculation are

equipped with two low water warning sensors controlled by

the “SUMMER/WINTER” switch in the cab. In cold weather

the switch should be in the WINTER position. This allows more

water to remain in the tank to accommodate recirculation.During warmer weather, the switch should be in the SUMMER

position, providing more water for jetting operations.

®PRINCIPLES OFOPERATIONCaution: Although the water pump may be run for a short time without water, prolonged operation of the water

pump without water will cause overheating and damage to the packings and other internal components of the water

pump. Refer to the pump manufacturer’s section included in this manual for further information.

THE REAR OPERATOR’S STATIONThere are actually two operator’s stations, depending on the function

being performed. For operating the jetting and vacuum functions of

the machine, the operator will use the rear operator’s station, located

on the hose reel frame at the rear of the unit. The operator’s station is

equipped with an electronic throttle switch to control the engine speed,

a tachometer to view the engine’s speed, a water pressure gauge to view

the water pressure in the jetting system, and a vacuum gauge to view

the performance of the vacuum system and switches to turn water pump

and blower on and off. There may also be a water warning light on

the rear station control panel. The two buttons on the lower part of the

panel control the articulation of the hose reel assembly. It is possible to

articulate this hose reel 180º around to the side of the machine so that

the hose reel and operator’s station is all the way to the passenger side

of the machine. This allows the operator to be completely away from the

ow of trafc if practical. It also allows direct access to manholes which

are located on the tree lawn or sidewalk, while the truck can be parked

along the curb-side. One button will cause the hose reel assembly to

articulate out away from the tank door, and the other will bring the hose

reel assembly back to rest on the door stop pad.

Caution: Always move the hose reel away from the door stop pad whenever the

hose reel will be operated. Failure to do so may cause the door stop pad to be tornaway from the reel

There is also a toggle switch which controls the engine speed. Push-

ing up the switch increases the engine speed, while pushing it down

decreases the engine speed.

THE REAR REEL CONTROLS

In addition to the controls at the rear operator’s station, several valves

and controls are also mounted directly to the rear reel assembly at the

back of the machine. This is where most of the work is done. When

work is done at the side of the machine, all the controls and the opera-tor’s station come with the reel as it articulates. Among the controls at

the rear reel is the water valve handle to turn water on at the hose reel.

Plastic labels indicate which position turns water on to the hose reel

and which returns water to the water tanks. When in the hose reel posi-

tion, the water ow is directed to the hose reel and through the water

hose. Be sure the hose is tted with a proper nozzle and in a working

position before turning the valve to the hose reel position.When in the

tank return position, water ows through the control valve and returns

to the water tanks. This is the normal position for the valve whenever

the machine is not being used for jetting.

®PRINCIPLES OFOPERATION HOW TO USE YOUR SEWER CLEANER

IMPORTANT SAFEGUARDS

1. Never enter a manhole that has stagnant water in it. 2. When entering a manhole, proceed as recommended in the APWA handbook on safety. Follow all

state and federal regulations.

3. Use only genuine Aquatech hose and repair parts.

4. Always use a hose guide in the manhole.

5. Always use a leader hose at the end of the sewer cleaning hose.

6. Use Cold Weather Recirculation in temperatures below 32o F.

7. Check hose and water network for weak, worn or leaking places. Repair or replace if necessary.

8. When inserting a nozzle in a sewer section full of water or in very large diameter pipes, use extreme

caution when applying pressure to the hose. Deection is possible under these conditions and the nozzle

could turn around, come up and out of the line and manhole to inict injury to persons nearby.

9. Never force nozzle or hose forward by pushing on it. It must move under its own water power.

10. Always use a steel nozzle guide or nozzle extension longer than the pipe diameter.

11. Check for overhead lines that could come in contact with the boom.

Before proceeding with the following instructions make certain that there is at least 90 psi of air pressure in the

chassis air reservoir or damage to the PTO may result.

BEFORE GOING TO WORK SITE

1. Perform required maintenance as specied in the maintenance schedule.

2. Perform required maintenance on truck chassis as specied in truck chassis manual.

3. Check to see that the boom is secure in the boom rest and latched and the boom pendant control is secure

in its carrier, toolbox, or cab.

4. Check to assure that all tools are secured, and that all cabinet doors are closed and latched.

5. Secure the sewer hose in the traveling position by locking it into the swivel tting provided.

6. Fill the water tanks. Please refer to one or more of the following water level indicators.

a. The sight tubes located on the rear of the water tanks shows the direct water level in all tanks.

b. Low water warning light in the cab indicates low water.

WATER JETTING AT THE WORK-SITE

1. Position the unit at the manhole to be cleaned so that the sewer hose will feed off the reel directly into

the manhole. Set the parking brake and block the wheels.

2. Open the water pump gate valve completely.

3. Place the water control valve on the hose reel to the “TANK RETURN” position.

4. Turn the unit power switch to the “ON” position. Turn the PTO enable switch to the “ON” position.

5. Disengage the rear axle by shifting the main drive of the split shaft PTO. The transmission must be

in neutral. On units with standard transmissions it is also advisable to depress the clutch pedal to the

oor during this operation. The middle switch on the three switch gang mounted to the dashboard or

the control box will operate the main drive of the split shaft PTO.

7. Excess water may be removed from the debris tank by the following

method. With the exhauster pump disengaged, open the drain valve

at the rear of the unit and allow the water to drain.

NOTE: Do not run the exhauster in reverse to pressurize the tank. This

may damage the clutches in the PTO.

LEAVING THE WORK SITE

1. Return hose reel to its travel position against the stop on the rear

door.

2. Before leaving the worksite for the dumpsite, ensure that the boom

is in its travel position.

3. Proceed to dumpsite.

DUMPING THE DEBRIS TANK

Caution: When dumping this vehicle, always seek rm, level terrain on which to

park the vehicle when setting up to dump. Never lift the tank when the unit is parked

on a grade, or when the underlying ground is soft or unstable. Failure to follow

these guidelines may result in a catastrophic accident in which the vehicle may tip

over or the tank may shear from its mounting supports.

Do not attempt to raise the tank until the door has been opened to allow the debris to

empty. Never drive this vehicle with the tank raised or the tank door opened.

1. Position the truck at the dump site, set the parking brake, and block

the wheels. BE SURE THE AREA ABOVE THE VEHICLE, IS FREE OF

ELECTRICAL LINES OR ANY OTHER OBSTRUCTIONS !2. Procedure for opening the rear door and raising the tank:

Note: Maximum operating speed for opening the rear door is shown on the

“unit identication sheet .”

a. Master power switch in the “On” position and PTO enable switch in the

“On” position.

b. Engage the hydraulic system. Disengage the drive axles by placing the

PTO switch in the “On” position.

c. Unlatch boom and using the boom pendant control, extend the boom out

a few inches, and raise it to its highest point.

d. Push and hold the toggle switch marked LOCKS upward to unlock the

hydraulic door locks.

ordering instructions.

The following method can be used to clean out the debris tank if unit is not equipped with optional Tank Flush

System: Connect the handgun to the quick disconnect or optional 1/2" hose reel. Engage the water pump. If yourunit is not equipped with the 1/2" hose reel, turn the water valve at the handgun quick disconnect to ON, allowing

the water to ow to the handgun. If your unit has the optional 1/2" hose reel, turn the valve located at the reel

to the ON position, increase the engine RPM with the throttle until the water pressure reaches 800 PSI on the

pressure gauge. Do not exceed this pressure setting when operating.

HELPFUL HINTS FOR USING YOUR AQUATECH CLEANER

WHERE TO START YOUR CLEANING PROGRAM

Cleaning operations should begin at the outer reaches of the network, proceed to trunk lines

and then to interceptors. Deposits must be removed by the crew as cleaning proceeds. The 15o

nozzle is recommended for optimum cleaning of the tile in sections where accumulations arelight or pipe diameters do not exceed 12 inches. If accumulations are heavy, the 35

o nozzle

is recommended.

WATER LEVEL INDICATORS

It is important to pay attention to the amount of water remaining in the fresh water tanks when using

the hose reel. There are two ways of determining the amount of water remaining:

1. The sight level tube located on the water tanks which shows water level in both tanks.

2. Low water warning light, will come on when there is approximately 3 minutes of operation time

remaining. (Optional)

COLD WEATHER STORAGE

The following procedure is required to prevent damage to the water pump and water system during

cold weather conditions.

1. Open the drain in the water tank cross-over line, under truck chassis, behind the rear axle.

Leave the drain cap off until the machine is ready to be used.

2. Drain water from tanks by tipping the tank slightly. Once the water is removed, lower

the tank.

3. Remove the suction line lter, gasket and cover.

4. Turn the 3 way ball valve at rear reel water manifold to the “Hose Reel” position.

ELECTRICAL SYSTEMImportant! Do not attempt to remedy any electrical problems without first examining the schematic

wiring diagram and control wiring circuit drawing (see Electrical Section). Check truck chassis battery

and cell condition. Use proper instrumentation for current and continuity test results.

(A) Continuity- Use OHM scale recorder or battery powered continuity test light.

(B) Current- The circuit must be opened to obtain current reading with the volt- meter;

therefore, it is more convenient to use a 12 VDC test light.

POLYTANK REPAIR

General Informaon

Repairs to polyethylene tanks can be performed easily with a miniInurn of training. Repair technicians must exercise prudent cautionagainst melting completely through the poly material, but extreme caution is generally not necessary. What this means is that the tech-

nician must realize that dire consequences are possible but not likely if he/she is reasonably careful.

Typical repairs will involve repair of two basic types of damage: blernishes to the surface, and cracks or holes through the material. Adierent repair approach will be appropriate for each type of damage.

Blemish repairs

Blemishes to the surface of the poly tank can usually be repaired by rst cleaning the area to remove any grease, oil or dirt. Thenapply heat using an electric heat gun. Such guns, in the range of 1000 to 1300 watts allow the application of heat in controllableamounts to avoid quick burn through which is possible with a ame such as f rom a propane torch. Aquatech does not recommendthe use of a torch to repair poly tanks.

Using the heat gun, and varying the distance of the gun from the surface of the material, work the heat in a circular motion around theblemished area until the surface begins to become shiny. At this point the technician should become Vely careful as the poly material

is beginning to liquefy and will begin to ow. By allowing just enough ow to ll any surrounding blemishes, and using a smooth metalobj ect such as a spoon or spatula, the material can be manipulated and be made smooth. In cases where the material may have beenheavily gouged, and some material has been lost, the use of a stick of polyethylene material melted into the aected area can help llit, then the tool can restore the smooth surface.

Cracks and holes

When a crack or hole has developed in the polyethylene material another approach is advisable. Cleaning the aected area is veryimportant. It may be necessary to scrape away some of the material if it is badly contaminated with grease, oil or dirt. The repair is bestdone when it can be approached from both sides, although there are cases where this will clearly be impossible.

Using an electric soldering gun with a wide, at tip suitable for working with plastics, dip the hot tip into granulated polyethylene(provided by Aquatech) and work small amounts into the crack or hole. Repeat as many times as necessary to build the aected areaup to the surrounding surface. Repeat the procedure on the opposite side if possible.

Use a smooth metal tool such as a spoon or spatula to work the material to conform with the surrounding surface. A heat gun may used

as a nal step to completely smooth the area, but is not required.

Areas repaired with either technique will have all the qualities and properties of strength and stability as the original area. Repairedsections can be put into service immediately upon cooling.

Recommended tools

Tools recommended are a heat gun, 1000-1300 watts. Several manufacturers oer such a gun in the price range of US$60.00 to US$150.00. Some manufacturers include Master, Weller and Ideal. These heat guns are also excellent tools for thin wall shrink tubing andspecial solder/shrink electrical terminals. A soldering gun capable of accepting altemate tips is also recommended. Such soldering gunscan be purchased at electronic supply houses such as Radio Shack, or at common retail outlets such as Sears. Weller is a respectedmanufacturer of good soldering tools. Forming tools which are metal and smooth can be made from common items such as kitchenutensils, or purchased from body shop suppliers. Since many dierent applications are possible, experience is the best judge ofwhich particular tool to obtain.

and splash guard are tacked on the ends for shipping. They will need readjusting

for assembly. The bumper assembly has one horizontal bar with two vertical bars

extending from the horizontal bar. The splash guard is a at rectangular sheet of

metal that is weld onto the top of the vertical bars. The two sections are mounted

to the rear of the tank. When the tank is in tipping operation the bumper and splashguard will tip with the tank when properly mounted. This provides for a smooth

run-off when the debris tank is being emptied.

It is important to mount the bumper and splash guard in the proper location. This

will prevent problems when dumping and tipping the debris tank.

On the bottom rear of the debris tank is the tank hinge assembly. The hinges are

on the left and right sides of the debris tank. At the bottom of the debris tank,

just below the tank opening, is the “cover plate bumper mount.” The cover plate

bumper mount is positioned between the left and right tank hinge assembly. Weld

the bumper and splash guard to the cover plate bumper mount.

Mounting the bumper:

Locate the center of the cover plate bumper mount and the center of the bumper

assembly. Align the two centers together. Leave approximately ¼" space from the

bottom edge of the cover plate bumper mount when mounting the bumper assem-

bly to the cover plate bumper mount. When welding the bumper to the cover plate

bumper mount, it is helpful to have two additional persons to hold the bumper in

position. Weld the bumper to the cover plate bumper mount.

Mounting the splash guard:

Once the bumper assembly is mounted to the tank, weld the splash guard to the

bumper assembly. Place the guard on top of the bumper assembly vertical bars

extending from the cover plate bumper mount. The guard should t perfectly onto

the bumper assembly. If the guard is a little long or short, adjust it to t snugly to

the bumper. When the guard is in place weld it to the bumper.

NOTE: Do not weld the bumper and splash guard to the truck chassis. This will

cause difculty when dumping and tipping the unit. The bumper assembly was

designed to tip with the debris tank. If you have any question regarding mounting

procedures contact our service department at 1-800-800-1016.

REMOTE FLOW-SELECT WATER REGULATOR SYSTEM

All “B” series units with the optional “Remote Flow-Select Water Regulator System” have the controlsincorporated at the rear reel operator’s station.

The Water Flow “ON-OFF” Valve (Item #1) provides control of the water system ow. The function

of this valve is to direct the water ow to the hose reel water manifold (in the “ON” position), or back to

the water tanks (in the “OFF” position).

The Water Flow Adjustment Valve (Item #2) provides control for the amount of ow directed to the

hose reel or back to the tank. By turning the adjustment knob of this valve clockwise, the amount ofwater directed to the hose reel increases. By turning the knob counterclockwise, the amount of waterdirected to the hose reel decreases.

To lower water pressure, push the water ow handle down (off position), then reduce the air pressure

to 0 psi by turning the water ow adjustment.

To raise water pressure, pull the water ow handle up (on position), then raise the air pressure todesired psi by turning the water ow adjustment.

The operation of the standard Three Way Water Control Valve remains the same as the standard unit.
