A gate valve may be installed in-line on the delivery side (outlet port) of the

pump which can be adjusted as required to regulate the flow of water, and

can assist in priming the pump.

CAUTION: DO NOT PLACE ANY SUCH OBSTRUCTION ON THE SUCTION (INLET) SIDE

OF THE PUMP UNLESS IT IS AN ISOLATOR VALVE IN A GRAVITY FED SYSTEM. THESE

PUMPS SHOULD NOT BE OPERATED WITH THE DELIVERY VALVE COMPLETELY

CLOSED.

To prevent unnecessary strain or possible distortion to the pump, ensure that

adequate support is provided to the hoses and or pipes. They will be

considerably heavier when filled with water.

Should contaminants come into contact with the pump, flush through with

cold water as soon as possible to prevent damage to the pump.

Protect the pump and pipework from freezing. The formation of ice may

cause serious damage.

Where the pump is to be a permanent fixture, the connections to the pump

MUST be flexible, i.e. a short piece of hose should be inserted between the

rigid pipework and the pump.

IMPORTANT: An air leak in the suction line will inhibit priming and reduce the

capacity of the pump.

Pay particular attention to the following:

• Keep all hoses as short and straight as possible and avoid sharp

bends.

• Ensure there is adequate drainage for the discharged water.

• If a flexible hose must be laid across a roadway, protect it with

planking.

(Instantaneous shut off pressure, applied when a vehicle runs across an

unprotected hose, could cause "hydraulic shock", which can damage the

pump and/or the hose).

CONNECTING A FOOT VALVE/FILTER

1. Attach a foot valve/filter to the end of the suction hose to prevent stones

etc, from being drawn up, which could cause damage to the pump. Keep

the strainer clean. If it is likely to clog with dirt or debris, proceed by either:

• Preparing a bed of stones on which to rest the strainer.

• Tying the strainer so that it stays clear of the bottom of the pit, pond

or excavation.

• Tie the strainer inside a basket or bucket.
