OPERATION AND MAINTENANCE MANUAL

HIPPOTM

VACUUM SYSTEM

DESCRIPTION

Scomi Oiltools HippoTM Vacuum System is a perfect vacuum cleaning unit for your onshore and offshore

application. Fully air-operated, it does not require any electrical power source. Portable and robust,

skid-mounted designed, the unit can be use to recover liquid and sludges and ideal for cleaning ditches,

cellars, and pumps. The unit constructed from stainless steel material to withstand corrosion.

A suction force is created by introducing air at a specified flow rate and pressure through the vacuum

head and creating a vacuum condition inside the main tank. When the tank is full, a shut-off assembly

system will close the vacuum head thus prevent the unit to perform further suction.

SPECIFICATION

Tank capacity : 30 Gallon

Maximum suction : 17.5 Hg

Air requirement : 100 CFM @ 100 Psi

Tank and frame materials : Stainless Steel

Pump type : Air-operated double diaphragm pump

Drawing and part name : provided on page 4

Dimension : 37 (L) x 27 (W) x 47 (H)

Gross weight : 695 Lbs

CAUTIONS AND GENERAL SAFETY

Isolate, tag out, and disconnect air supply to the unit prior to working on any part of the system. Lift the unit only at provided lifting point or handling by using forklift truck from the forklift pocket.

Lifting from any point other than the provided lifting point could damage the unit.

The structure on which the unit is to be placed must be capable of supporting the operational weightof Hippo

TMVacuum System.

The unit should be operated in a safe area where walkways, lighting, and handrails are appropriateand allow safe access for operating and maintaining the equipment.

Ensure all hoses are in good condition, correctly rated and fitted. Air pressure applied to the unit should never exceed rated pressure.

OPERATING INSTRUCTIONS

To operate the unit, connect the airline between the air manifold and air supply. Use a minimum of 3/4

hose suitable to deliver compressed air at 100 psi. Make sure all the valves on air manifold are in OFF

position. The Chicago, or twist-lock fitting, connect and disconnect by pushing in and twisting. Be sure to

connect them securely by twisting them until they stop and the safety clip pins are aligned. HippoTM

Vacuum System is designed to work optimally at 100 cubic feet per minute (CFM) at 100 pounds per

square inch (Psi). Air supplies that dont meet these minimums will drastically reduce the performance.

Next, connect the 2 suction hose and 2 discharge hose

to their respective nozzle. Camlock connection provides

an easy connection and disconnection between hoses

and unit. Make sure rubber gasket is available inside

female type of camlock coupling.

Standard unit supplied with 15 Lg suction hose and 5 Lg

discharge hose. Instal vacuum wand kit at the end of

suction hose and secure it using double bolt clamp.

Carefully turn the main ball-valve at the air manifold to

ON position. Slowly fully-open the valve to introduce air

to the vaccum head. The unit is now ready for operation.

Shut-off assembly system will prevent the tank from overfull. When the contents reach maximum level,

this system will block the vacuum head for creating vacuum inside the tank, thus cease the suction

force. The tank will need to be drained before unit ready for another use. Close all the valves now.

Set out discharge hose to the discharge point, ensure

there is no danger to personnel from the discharge.

Slowly open the valve that deliver air to diaphragm

pump. Regulate the air pressure by turning the adjusting

knob and maintain at 25 ~ 30 Psi, refer to the pressure

gauge on air regulator. Run the pump for a couple of

cycles to empty the tank. The unit is now ready for

another operation.

TROUBLESHOOTING

Before checking anything else ensure the correct pressure and quantity of compressed air is being

supplied to the unit.

PROBLEM PROBABLE CAUSE REMEDY

Unit not operating at allToo low / high supply air

pressure.

Ensure correctly rated compressor is used.

Ensure air hose are correct diameter.

Blocked suction line. Unblock the suction line.

Low supply pressure. Ensure compressed air introduced at

correct rating.

Leakage on suction hose. Replace the suction hose.

Tank not sealed correctly. Tighten the top-flange. Use silicone

sealant if necessary.

Unit operating but not

loading material or low

vacuum

Material too viscous for

the unit.

Add liquid to the material.

Discharge line blocked. Unblock the discharge line.

Diaphragm pump not

dischargingPump is broken.
