1.

Pump – The model QP-402H is a 4-inch centrifugal pump

 

used in general de-watering applications. Typical

 

dewatering applications consist of dewatering basements

 

and swimming pools.

2.

Fill Cap – Prior to operation, the pump casing should be

 

filled with water.Remove this cap to add water to the pump.

 

After the initial prime, a sufficient amount of water will be

 

retained in the casing so that the operator will not need to

 

re-prime later.

 

If the casing is dry or has insufficient water, the pump will

 

have difficulty in priming which could lead to premature

 

mechanical seal wear thus causing damage to the pump.

3.

Discharge Port – Connect a 4-inch discharge hose to this

 

port.

4.

Worm Clamp – Used to secure the hose to the inlet and

 

outlet ports on the pump. Use two clamps to secure the

 

hose on the inlet side of the pump.

5.

Discharge Hose – Connect this flexible rubber hose to

 

the discharge port on the pump. Make sure that the hose

 

lays flat and is not kinked. Use only recommended type

discharge hose. Contact Multiquip parts department for ordering information.

6. Suction Port – Connect a 4-inch inlet hose to this port. Use two worm clamps to secure the hose.

7. Suction Hose – Connect this flexible rubber hose to the suction port on the pump. Make sure that the hose lays flat and is not kinked. Use only recommended type suction hose. Contact Multiquip parts department for ordering information.

8. Drain Plug – Remove this plug to drain water from the pump.

9. Strainer – Always attach a strainer to bottom side of the suction hose to prevent large objects and debris from entering the pump. Strainer should be positioned so that it will remain completely under water.Running the pump with the strainer above water for long periods can damage pump.
