automatically. No component alignment or adjustments are
necessary.
• Be gentle and patient, the coupling is precisely engineered
and no great force is required to connect the accessories.
Once the operator has mastered the ‘technique’,
accessory connection will become straight forward.
• Firmly push the engine and accessory together until the
‘click’ of docking is heard. The Uni-coupling release lever
will return to its neutral position.

2. Connecting the Hoses
Note:
Hoses should be independently supported. They
should not be carried by the pump.
• Check the integrity of the hoses. There must be no
damage to either the inlet or discharge hose.
• Connect the hoses to the pump body using the hose
clamps and gaskets supplied.
(Fig. 3)
Check that the gaskets are correctly seated.
Note:
Any air leak in the inlet (suction) hose could prevent
priming and reduce the flow rate of the pump.
• If using fixed steel pipework always ensure that the
connection to the pump body is made with a piece of
flexible hose at least 300mm long.
• Keep all pipes and hoses as short and straight as possible,
and try to avoid sharp turns.
• Ensure that the discharged water has an adequate
drainage channel.
• If any flexible hose is laid across a roadway or similar, protect
the hose from vehicular traffic with wooden planking.
• A suction strainer should be attached to the end of the
inlet hose. It is important to prevent large pieces of debris
or stones etc from being drawn into the pump body and
damaging the impellor.
• The inlet hose may need to be weighted down to keep it
in position in the pond or excavation pit etc.
Note:
If a vehicle were to run over an unprotected flexible
hose, the instant crushing of the hose, and consequent
stoppage of the water flow could cause ‘hydraulic shock’.
This could damage the pump and/or its fittings.
