Multiquip MP150SDLSM Setup, DANGER - High Pressure, CAUTION - Strainer Placement, Before Starting

Before Starting

1.Read safety instructions at the beginning of manual.

2.Placepumpasneartowateraspossible.Levelthepumpwith jackstands.Rearjackstandonsuctionendofthepumpmust be used as the weight of the suction hose filled with liquid could cause the pump to tip.The jack stands can be moved fromsidetosideandoptionalextrajackstandscanbeadded.

3.Fill the vacuum system with water. Water level should be up to the middle of the hose below the priming system tank fill reservoir. Fill with clean water, free of solids or foreign material.Donotusesaltwater,waterwithabrasives,oracidic waterasthiswillcausedamagetothesystem.Non-polluting, environmentally-safe antifreeze should be used in freezing conditions.

Pump will not be able to begin

NOTE pumping unless the water level is up to the middle of the hose below the fill port tank.

4.Checkforleaksbetweenpumpandengine.Ifwaterisleaking between the pump and bearing housing, the seal inside the pumpmaybewornordamaged.Continued operationofthe pumpisnot recommended.Furtherusageofthe pumpunder theseconditionsmaycauseseverewaterdamagetobearing housing assembly.

Suction and Discharge Hoses

1.Check that the suction hose is securely attached to the pump. Make certain suction hose (Figure 3) does not have any air leakage. Tighten hose clamps and couplings as required.

2.Shorter suction lift and suction hose length will produce betterperformance.

3.Make sure the suction strainer (Figure 6) is clean and securely attached to the water end of the suction hose.The strainer is designed to protect the pump by preventing large objects from being pulled into the pump. Failure to use a strainer could cause damage to the pump, impeller, pump shaft, pump bearings, or wear plate.

4.Ifastrainerbecomescloggedwithdebris,thestrainercanbe cleared while the pump is running by opening the backflush valve.

SETUP

DANGER - High Pressure

PVC discharge hoses and thin-walled rubber hoses can easily fail at the end of

the hose fittings. Leaks from the hoses can cause high-pressure liquid to be discharged, causing dangerous conditions. Make sure pressure rating of

hoses exceeds the pump maximum pressure to prevent hose failure.

CAUTION - Strainer Placement

The strainer should be positioned so it will remain completely under water. Running the pump with the strainer above water for long periods can damage the pump.

5.Multiple suction lines may be used but valves need to be installedinalllinestoadjustfordifferentflowsandsuctionlift. Suction lines of lengths of 1000 feet or more will lower performance of the pump.

6.Check that the discharge hose (Figure 6) is securely at- tachedand notrestricted.Placehosesothat it laysas straight as it is possible on the ground. Remove any twists or sharp bends from hose which may block the flow of water.

7.Light discharge hose should be anchored to avoid move- ment with high flow or high pressure.

Suction and discharge hoses are

NOTE available from Multiquip. Contact your nearest dealer for more information.

DANGER - Flammable Fluids

DO NOT pump flammable fluids, corrosive chemicals or fluids containing toxic substances. These fluids can create potentially dangerous health and environmental hazards. Contact local authorities for assistance.

8.Always use a suction hose or pipe that matches the size of the pump inlet to insure optimum performance and reduce the risk of damage to the pump.

9.It is recommended that the discharge hose or pipe match the size of the pump outlet to reduce friction as much as possible. Using a discharge line that is larger than the pump outlet will reduce friction and improve water flow.Similarly, a smaller line will reduce water flow by increasing friction.
