- i -

• Do not use refrigerant other than the type indicated in the manuals provided with the unit and on the nameplate.

- Doing so may cause the unit or pipes to burst, or result in explosion or � re during use, during repair, or at the time of disposal of the unit.

- It may also be in violation of applicable laws.- MITSUBISHI ELECTRIC CORPORATION cannot

be held responsible for malfunctions or accidents resulting from the use of the wrong type of refrigerant.

• Do not use steel pipes as water pipes. - Copper pipes are recommended. • The water circuit should be a closed circuit. • Ask the dealer or an authorized technician to

install the air conditioner.- Improper installation by the user may result in water

leakage, electric shock, or � re.• Install the unit in a place that can withstand its

weight.- Inadequate strength may cause the unit to fall down,

resulting in injuries.• Do not touch the unit. The unit surface can be hot.• Do not install the unit where corrosive gas is

generated.• Use the speci� ed cables for wiring. Make the

connections securely so that the outside force of the cable is not applied to the terminals.

- Inadequate connection and fastening may generate heat and cause a � re.

• Prepare for rain and other moisture and earthquakes and install the unit at the speci� ed place.

- Improper installation may cause the unit to topple and result in injury.

• Always use an strainer and other accessories speci� ed by Mitsubishi Electric.

- Ask an authorized technician to install the accesso-ries. Improper installation by the user may result in water leakage, electric shock, or � re.

• Never repair the unit. If the air conditioner must be repaired, consult the dealer.

- If the unit is repaired improperly, water leakage, electric shock, or � re may result.

• Do not touch the refrigerant pipes and Water pipes.

- Improper handling may result in injury.• When handling this product, always wear protec-

tive equipment. EG: Gloves, full arm protection namely boiler suit,

and safety glasses.- Improper handling may result in injury.• If refrigerant gas leaks during installation work,

ventilate the room.- If the refrigerant gas comes into contact with a � ame,

poisonous gases will be released.• Install the unit according to this manual.- If the unit is installed improperly, water leakage,

electric shock, or � re may result.• Have all electric work done by a licensed electri-

cian according to “Electric Facility Engineering Standard” and “Interior Wire Regulations” and the instructions given in this manual and always use a special circuit.

- If the power source capacity is inadequate or electric work is performed improperly, electric shock and � re may result.

• Keep the electric parts away from water (washing water etc.).

- It might result in electric shock, catching � re or smoke.

• Securely install the heat source unit terminal cover (panel).

- If the terminal cover (panel) is not installed properly, dust or water may enter the heat source unit and � re or electric shock may result.

• When installing and moving the air conditioner to another site, do not charge it with a refrigerant different from the refrigerant (R410A) speci� ed on the unit.

- If a different refrigerant or air is mixed with the origi-nal refrigerant, the refrigerant cycle may malfunction and the unit may be damaged.

Safety Precautions

- ii -

• Do not use the existing refrigerant piping.- The old refrigerant and refrigerant oil in the existing

piping contains a large amount of chlorine which may cause the refrigerant oil of the new unit to dete-riorate.

- R410A is a high-pressure refrigerant and can cause the existing piping to burst.

• Use refrigerant piping made of C1220 (CU-DHP) phosphorus deoxidized copper as speci� ed in the JIS H3300 “Copper and copper alloy seamless pipes and tubes”. In addition, be sure that the in-ner and outer surfaces of the pipes are clean and free of hazardous sulphur, oxides, dust/dirt, shav-ing particles, oils, moisture, or any other contami-nant.

- Contaminants on the inside of the refrigerant piping may cause the refrigerant residual oil to deteriorate.

• Store the piping to be used during installation indoors and keep both ends of the piping sealed until just before brazing. (Store elbows and other joints in a plastic bag.)

- If dust, dirt, or water enters the refrigerant cycle, deterioration of the oil and compressor trouble may result.

• Apply a small amount of ester oil, ether oil, or alkyl benzene to � ares. (for indoor unit)

- In� ltration of a large amount of mineral oil may cause the refrigerant oil to deteriorate.

• Use liquid refrigerant to � ll the system.- If gas refrigerant is used to seal the system, the

composition of the refrigerant in the cylinder will change and performance may drop.

• Do not use a refrigerant other than R410A.- If another refrigerant (R22, etc.) is mixed with

R410A, the chlorine in the refrigerant may cause the refrigerant oil to deteriorate.

• Use a vacuum pump with a reverse � ow check valve.

- The vacuum pump oil may � ow back into the refrig-erant cycle and cause the refrigerant oil to deterio-rate.

• Do not use the following tools that are used with conventional refrigerants.

(Gauge manifold, charge hose, gas leak detector, reverse � ow check valve, refrigerant charge base, refrigerant recovery equipment)

- If the conventional refrigerant and refrigerant oil are mixed in the R410A, the refrigerant may deterio-rated.

- If water is mixed in the R410A, the refrigerant oil may deteriorate.

- Since R410A does not contain any chlorine, gas leak detectors for conventional refrigerants will not react to it.

• Do not use a charging cylinder.- Using a charging cylinder may cause the refrigerant

to deteriorate.• Do not use antioxidant or leak-detection additive.• Be especially careful when managing the tools.- If dust, dirt, or water gets in the refrigerant cycle, the

refrigerant may deteriorate.

• If the air conditioner is installed in a small room, measures must be taken to prevent the refriger-ant concentration from exceeding the safety limit even if the refrigerant should leak.

- Consult the dealer regarding the appropriate meas-ures to prevent the safety limit from being exceeded. Should the refrigerant leak and cause the safety limit to be exceeded, hazards due to lack of oxygen in the room could result.

• When moving and reinstalling the air conditioner, consult the dealer or an authorized technician.

- If the air conditioner is installed improperly, water leakage, electric shock, or � re may result.

• After completing installation work, make sure that refrigerant gas is not leaking.

- If the refrigerant gas leaks and is exposed to a fan heater, stove, oven, or other heat source, it may gen-erate noxious gases.

• Do not reconstruct or change the settings of the protection devices.

- If the pressure switch, thermal switch, or other protection device is shorted and operated forcibly, or parts other than those speci� ed by Mitsubishi Electric are used, � re or explosion may result.

• To dispose of this product, consult your dealer.• The installer and system specialist shall secure

safety against leakage according to local regula-tion or standards.

- Following standards may be applicable if local regu-lation are not available.

• Pay a special attention to the place, such as a basement, etc. where refrigeration gas can stay, since refrigeration is heavier than the air.

- iii -

• Do not install the unit where combustible gas may leak.

- If the gas leaks and accumulates around the unit, an explosion may result.

• Do not use the air conditioner where food, pets, plants, precision instruments, or artwork are kept.

- The quality of the food, etc. may deteriorate.• Do not use the air conditioner in special environ-

ments.- Oil, steam, sulfuric smoke, etc. can signi� cantly reduce

the performance of the air conditioner or damage its parts.

• When installing the unit in a hospital, communica-tion station, or similar place, provide suf� cient protection against noise.

- The inverter equipment, private power generator, high-frequency medical equipment, or radio commu-nication equipment may cause the air conditioner to operate erroneously, or fail to operate. On the other hand, the air conditioner may affect such equipment by creating noise that disturbs medical treatment or image broadcasting.

• Do not install the unit on a structure that may cause leakage.

- When the room humidity exceeds 80 % or when the drain pipe is clogged, condensation may drip from the indoor unit. Perform collective drainage work together with the unit, as required.

- iv -

• Ground the unit.- Do not connect the ground wire to gas or water

pipes, lightning rods, or telephone ground lines. Improper grounding may result in electric shock.

• Install the power cable so that tension is not applied to the cable.

- Tension may cause the cable to break and generate heat and cause a � re.

• Install a leak circuit breaker, as required.- If a leak circuit breaker is not installed, electric shock

may result.• Use power line cables of suf� cient current

carrying capacity and rating.- Cables that are too small may leak, generate heat,

and cause a � re.• Use only a circuit breaker and fuse of the

speci� ed capacity.- A fuse or circuit breaker of a larger capacity or a

steel or copper wire may result in a general unit failure or � re.

• Do not wash the air conditioner units.- Washing them may cause an electric shock.• Be careful that the installation base is not

damaged by long use.- If the damage is left uncorrected, the unit may fall

and cause personal injury or damage property.• Install the drain piping according to this manual to

ensure proper drainage. Wrap thermal insulation around the pipes to prevent condensation.

- Improper drain piping may cause water leakage and damage to furniture and other possessions.

• Be very careful about product transportation.- If the unit weighs more than 20kg, carry the unit with

more than one person.- Some products use PP bands for packaging. Do not

use any PP bands for a means of transportation. It is dangerous.

- When transporting the unit, support it at the speci� ed positions on the unit base. Also support the unit at four points so that it cannot slip side ways.

• Safely dispose of the packing materials.- Packing materials, such as nails and other metal or

wooden parts, may cause stabs or other injuries.- Tear apart and throw away plastic packaging bags

so that it is out of reach of children. If children play with a plastic bag which was not torn apart, they face the risk of suffocation.

- v -

• Turn on the power at least 12 hours before starting operation.

- Starting operation immediately after turning on the main power switch can result in severe damage to internal parts. Keep the power switch turned on during the operational season.

• Do not touch the switches with wet � ngers.- Touching a switch with wet � ngers can cause elec-

tric shock.• Do not touch the refrigerant pipes during and im-

mediately after operation.- During and immediately after operation, the

refrigerant pipes are may be hot and may be cold, depending on the condition of the refrigerant � owing through the refrigerant piping, compressor, and other refrigerant cycle parts. Your hands may suffer burns or frostbite if you touch the refrigerant pipes.

• Do not operate the air conditioner with the panels and guards removed.

- Rotating, hot, or high-voltage parts can cause injuries.

• Do not turn off the power immediately after stopping operation.

- Always wait at least � ve minutes before turning off the power. Otherwise, water leakage and trouble may occur.

• Do not touch the surface of the compressor during servicing.

- If unit is connected to the supply and not running, crank case heater at compressor is operating.

• Do not touch the panels near the fan outlet with bare hands: they can get hot while the unit is in operation (even if it is stopped) or immediately after operation to prevent burns. Wear gloves to protect your hands when it is necessary to touch the panels.

• While the unit is in operation or immediately after operation, high-temperature exhaust air may blow out of the fan exhaust outlet. Do not hold your hands over the outlet or touch the panels near the outlet.

• Be sure to provide a pathway for the exhaust air from the fan.

• Water pipes can get very hot, depending on the preset temperature. Wrap the water pipes with insulating materials to prevent burns.

2. Installation(1) Selecting an installation site (for PWFY unit)• Do not install outdoors. The unit is not waterproof.• Back up system is recommended in case of PWFY unit breakdown.• The unit will get hot. Do not install in a location where heat gets trapped inside. • Be sure to install unit in a place strong enough to withstand its weight. Any lack of strength may cause unit to fall down, resulting in a personal injury.• Do not install the unit where corrosive gas is generated.• Have installation work in order to protect against earthquake. Any installation de� ciency may cause unit to fall down, resulting in a personal injury.• Pay a special attention to the place, such as a basement, etc. where refrigeration gas can stay, since refrigera-

tion is heavier than the air.• Do not install the unit where combustible gas may leak.- If the gas leaks and accumulates around the unit, an explosion may result.• When installing the unit in a hospital, communication station, or similar place, provide suf� cient protection

against noise.- The inverter equipment, private power generator, high-frequency medical equipment, or radio communication

equipment may cause the air conditioner to operate erroneously, or fail to operate. On the other hand, the air conditioner may affect such equipment by creating noise that disturbs medical treatment or image broadcasting.

• Do not install the unit on a structure that may cause leakage.- When the room humidity exceeds 80 % or when the drain pipe is clogged, condensation may drip from the indoor

unit. Perform collective drainage work together with the unit, as required.• It is recommended that a water pump is connected to each PWFY unit.

(1)-1 Securing installation and service space• Please secure the following service spaces after installation. (All servicing can be performed from the front of the unit) [Fig. IV. 2. (1). 1]

Warning:• Be sure to install the unit in a location which can adequately support its weight.- If there is insuf� cient strength to support the unit’s weight, it could fall and cause injuries.

(4) Connecting refrigerant pipes and drain pipes

(4)-1 Refrigerant piping workThis piping work must be done in accordance with the installation manuals for outdoor unit (heat source unit).• For constraints on pipe length and allowable difference of elevation, refer to the outdoor unit installation manual.• The method of pipe connection is brazing connection.

Caution:• Install the refrigerant piping for the indoor unit in accordance with the following.1. Cut the tip of the indoor unit piping, remove the gas, and then remove the brazed cap. [Fig. IV. 2. (4). 1]

2. Pull out the thermal insulation on the site refrigerant piping, braze the unit piping, and replace the insulation in its original position.

Wrap the piping with insulating tape.Note:• Pay strict attention when wrapping the copper piping since wrapping the piping may cause condensation

instead of preventing it.* Before brazing the refrigerant piping, always wrap the piping on the main body, and the thermal insulation

piping, with damp cloths to prevent heat shrinkage and burning the thermal insulation tubing. Take care to ensure that the � ame does not come into contact with the main body itself.

Cautions On Refrigerant Piping

• Be sure to use non-oxidative brazing for brazing to ensure that no foreign matter or moisture enter into the pipe.

• e sure to apply refrigerating machine oil over the � are connection seating surface and tighten the connection using a double spanner.

• Provide a metal brace to support the refrigerant pipe so that no load is imparted to the indoor unit end pipe. This metal brace should be provided 500 mm away from the indoor unit’s � are connection.

Warning:When installing and moving the unit, do not charge it with refrigerant other than the refrigerant (R407C or R22) speci� ed on the unit.- Mixing of a different refrigerant, air, etc. may cause the refrigerant cycle to malfunction and result in severe damage.

Caution:• Use refrigerant piping made of C1220 (CU-DHP) phosphorus deoxidized copper as speci� ed in the JIS H3300

“Copper and copper alloy seamless pipes and tubes”. In addition, be sure that the inner and outer surfaces of the pipes are clean and free of hazardous sulphur, oxides, dust/dirt, shaving particles, oils, moisture, or any other contaminant.

• Never use existing refrigerant piping.- The large amount of chlorine in conventional refrigerant and refrigerator oil in the existing piping will cause the new

refrigerant to deteriorate.• Store the piping to be used during installation indoors and keep both ends of the piping sealed until just

before brazing.- If dust, dirt, or water gets into the refrigerant cycle, the oil will deteriorate and the compressor may fail.

(4)-2 Drain piping work

1. Ensure that the drain piping is downward (pitch of more than 1/100) to the outdoor (discharge) side. Do not provide any trap or irregularity on the way. (a)

2. Ensure that any cross-wise drain piping is less than 20 m (excluding the difference of elevation). If the drain piping is long, provide metal braces to prevent it from waving. Never provide any air vent pipe. Otherwise drain may be ejected.

3. Use a hard vinyl chloride pipe VP-25 (with an external diameter of 32 mm) for drain piping.4. Ensure that collected pipes are 100 mm lower than the unit body’s drain port as shown in (b). 5. Do not provide any odor trap at the drain discharge port.6. Put the end of the drain piping in a position where no odor is generated.7. Do not put the end of the drain piping in any drain where ionic gases are generated. [Fig. IV. 2. (4).3]

Sample of water circuit for PWFY

Consider the following when designing and installing a water piping system. (Items (1)-(12) in the � gure are explained below.) 1) Union joints/� ange joints etc. Install a � ange etc. to allow for easy replacement of connected equipment.2) Thermometer For checking unit performance and operation monitoring3) Water pressure gauge For operation status monitoring4) Valve Install a valve for easy replacement and cleaning of the refrigerant � ow control device. Install a refrigerant � ow control valve on the fan coil outlet side.5) Flexible joint Recommended to prevent the noise and vibration from the pump from being transmitted. 6) Drain pipe Install the drain pipe with an inclination of between 1/100 and 1/200 to provide a downward � ow of drain water. For cold climate installation, take an appropriate measure (e.g., drain heater) to prevent the drain water from

freezing.7) Pump Use a pump that is large enough to compensate for the total water pressure loss and to supply suf� cient water to the

unit.8) Air vent valve Provide air vent valves on the pipes.9) Expansion tank Install an expansion tank to accommodate expanded water and to supply water.10) Cold/Hot water pipe Use pipes that allow for easy air purging, and provide suf� cient insulation.11) Drain valve Install drain valves so that water can be drained for servicing.12) Strainer Install a strainer near the PWFY unit to keep foreign materials from entering the water-side heat exchanger. 13) Flow switch Install the supplied � ow switch on the outlet pipe.

(1)-1 Caution for water pipe installationConsider the following when designing and installing a water piping system.• Do not use steel pipes as water pipes.- Copper pipes or stainless steel pipes are recommended.If iron pipes are used in the existing system, do not connect

a new circuit to the old one. Keep the existing and new circuits separate. • Light pipes are similar to other air-conditioning pipes, however, please observe the following precautions during installation.• Before a long period of non use, purge the water out of the pipes and thoroughly let them dry. • Use a closed water circuit. • When operating the unit, add brine to the circulating water to prevent it from freezing. To use brine in the system,

DipSW 1-10 must be set to ON.• When installed in a low-ambient temperature environment, keep the water circulating at all times. If that is not

possible, purge the water out of the pipes completely. • Do not use the water used for this unit for drinking or food manufacturing.• When the ambient temperature is 0 �C or lower during stop operation, keep the water circulating at all times, or

purge the water out of the pipes completely.

joints are installed.PT 1 Screw*1 PT 1 Screw*1

(2) Selecting a water pumpUse a pump that is large enough to compensate for the total water pressure loss and to supply sufficient water to the unit.

(3) Installing the strainer• Install the strainer at the angle of 45� or less as shown in [Fig. IV 3.(3).1].• Install the supplied strainer at the water inlet.

(4) Precautions during installation• Use the reverse-return method to insure proper pipe resistance to each unit.• To insure easy maintenance, inspection, and replacement of the unit, use a proper joint, valve, etc. on the water

intake and outlet port. In addition, be sure to install a strainer on the water intake pipe. (In order to maintain the heat source unit, a strainer on the circulating water inlet is necessary.)

* An example of the heat source unit installation is shown in [Fig. IV 3.(5).1].• Install a suitable air vent on the water pipe. After sending water through the pipe, be sure to vent the excess air.• Compressed water may form in the low-temperature sections of heat source unit. Use a drainage pipe connected to

the drain valve at the base of the unit to drain the water.• Install a back � ow-prevention valve on the pump and a � exible joint to prevent excess vibration.• Use a sleeve to protect the pipes where they go through a wall.• Use metal � ttings to secure the pipes, and install them so that they have maximum protection against breakage and

bending.• Do not confuse the water intake and outlet valves.• This unit doesn’t have any heater to prevent freezing within tubes. When the water � ow is stopped on low ambient,

take out the water from tubes.• The unused knockout holes should be closed and the opening of refrigerant pipes, water pipes, power source and

transmission wires should be � lled with putty and so on to prevent from rain. (� eld construction)• Wrap some sealing tape around the screw part to prevent water leakage. • Wrap the sealing tape as follows. 1. Wrap the joint with sealing tape in the direction of the threads (clockwise), and do not let the tape run over the edge. 2. Overlap the sealing tape by two-thirds to three-fourths of its width on each turn. Press the tape with your � ngers so that it is pressed � rmly against each thread. 3. Leave the 1.5th through 2nd farthest threads away from the pipe and unwrapped.• Hold the pipe on the unit side in place with a spanner when installing the pipes or strainer. Tighten screws to a torque

of 50 N.m. • Water pipes can get very hot, depending on the preset temperature. Wrap the water pipes with insulating materials

to prevent burns. • Install the expansion joint (accessory) at the inlet after installing the strainer, and outlet.

(7) Flow switch installation<Caution>When installing the unit, be sure to install the supplied flow switch on the water outlet side of the unit and connect the wire to IN1 of TB142A on the unit.If the flow switch is not installed, the unit will emit the error signal (2100: Interlock error) and not operate.* A short-circuit wire is supplied, but it is only for test run.

- 27 -

<Installation procedures>1) Remove the pipes attached to the flow switch.

Note: The unit is shipped with the pipes loosely tightened. 2) Wrap seal tape around the threads at the end of the pipes, starting at the 1.5th or 2nd thread, and not over the

openings. Apply two to three wraps in the direction of the pipe threads (clockwise). Each course of the tape should overlap the one before it by 2/3 to 3/4 the width of the tape. Run your fingers around the threads and tape to press the tape into the threads.Then, attach the pipes to the flow switch, holding parts A and B with a spanner. The maximum tightening torque is 60 N•m (611 kgf•cm).

3) Attach the flow switch and pipes to the water outlet in the horizontal position.The angle of the axis of the pipe should be less than 45 degrees.Check the direction of the flow switch as shown in Fig. C.

4) Connect the flow switch wire to IN1 of TB142A.From the External Wiring Input, route the wire as shown in Fig. D and connect it to the terminal as shown in Fig. E. Use a wire protector such as a rubber bushing in the access hole on the unit.

(8) Water processing and water quality controlTo preserve water quality, use the closed type of cooling tower for unit. When the circulating water quality is poor, the water heat exchanger can develop scales, leading to a reduction in heat-exchange power and possible corrosion of the heat exchanger. Please pay careful attention to water processing and water quality control when installing the water circulation system.• Removal of foreign objects or impurities within the pipes. During installation, be careful that foreign objects, such as welding fragments, sealant particles, or rust, do not enter

the pipes.• Water Quality Processing

a) Depending on the quality of the cold-temperature water used in the air-conditioner, the copper piping of the heat exchanger may become corroded. We recommend regular water quality processing.Cold water circulation systems using open heat storage tanks are particularly prone to corrosion.When using an open-type heat storage tank, install a water-to-water heat exchanger, and use a closed-loop circuit on the air conditioner side. If a water supply tank is installed, keep contact with air to a minimum, and keep the level of dissolved oxygen in the water no higher than 1mg/liter.

b) Water quality standard

Reference : Guideline of Water Quality for Refrigeration and Air Conditioning Equipment. (JRA GL02E-1994)c) Please consult with a water quality control specialist about water quality control methods and water quality

calculations before using anti-corrosive solutions for water quality management.

d) When replacing a previously installed air conditioning device (even when only the heat exchanger is being replaced), � rst conduct a water quality analysis and check for possible corrosion.

Corrosion can occur in cold-water systems even if there has been no prior signs of corrosion.

If the water quality level has dropped, please adjust water quality suf� ciently before replacing the unit.Refer to the below graph for the maximum amount of circulating water in the water pipe. Make sure that this amount does not exceed.

1. Electrical work(1) General cautions

Warning:Electrical work should be done by quali� ed electrical engineers in accordance with “Engineering Standards For Electrical Installation” and supplied installation manuals. Special circuits should also be used. If the power circuit lacks capacity or has an installation failure, it may cause a risk of electric shock or � re.

1. Be sure to take power from the special branch circuit.2. Be sure to install an earth leakage breaker to the power.3. Install the unit to prevent that any of the control circuit cables (remote controller, transmission cables, or external

input/output line) is brought in direct contact with the power cable outside the unit.4. Ensure that there is no slack on all wire connections.5. Some cables (power, remote controller, transmission cables external input/output line) above the ceiling may be

bitten by mouses. Use as many metal pipes as possible to insert the cables into them for protection.6. Never connect the power cable to leads for the transmission cables. Otherwise the cables would be broken.7. Be sure to connect control cables to the indoor unit, remote controller, and the outdoor unit.8. Be sure to ground the unit.9. Select control cables from the conditions given in page 32.

Caution:Be sure to put the unit to the ground on the outdoor unit side. Do not connect the earth cable to any gas pipe, water pipe, lightening rod, or telephone earth cable. Incomplete grounding may cause a risk of electric shock.

(2) Power supply for PWFY unit(2)-1 Electrical characteristics of PWFY unit• Power supply cords of appliances shall not be lighter than design 245 IEC 57 or 227 IEC 57.• A switch with at least 3 mm contact separation in each pole shall be provided by the Air conditioner installation.
