ELECTRICAL CONNECTION
The pump should be located at a safe distance, (usually 2 metres), away from 
the pool, and the power supply should be at least 3.5 metres from the pool. If 
in doubt, please contact your electrical specialist and refer to the 
International Electrical Commission (IEC) standard, (Electrical Installations for 
Buildings-part 7), referring to ‘swimming pools and other basins’.
Avoid situations where the pump could become drenched with water as 
neither the motor or terminal box are designed to be waterproof. Ensure the 
pump & its cable do not create a safety hazard for people walking past it.
PIPE/HOSE CONNECTIONS
The pump inlet will be connected to the pool skimmer and/or pool drain 
connection, depending upon the installation layout, and the discharge outlet 
should be connected to your water filter.
The inlet and outlet adaptors supplied with the pump are designed to fit to 
rigid pipe-work. The inner bore diameter of the adaptors is 50 mm. Therefore 
pipes with the same nominal diameter should be used. These should be fixed 
in place using a proprietary adhesive/sealant suitable for pressurised pipework 
applications.
These can be extended with the use of suitable 50 mm I/D hose secured with a 
worm drive clip. Ensure all connections are air tight. Tighten them enough to 
secure the hose during pressurised operation, but not so tight as to crack the 
plastic inlet/outlet connectors.
Where the pump is to be a permanent fixture, vibration and strain on adjacent 
parts can be reduced by the insertion of a short flexible section of hose 
between any rigid pipework and the immediate area of the pump.
Any air leaks in the suction line will inhibit priming and reduce the capacity of 
the pump. Ensure there are no kinks in any flexible hose used.
The performance of your pump will be affected by the diameter of the inlet 
pipe - any restriction will greatly reduce the flow. We recommend that you 
always use a pipe diameter at least equal to, or greater than the diameter of 
the pump connections i.e. 50 mm diameter.
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.
It is suggested that suction and delivery isolation valves are fitted in order to 
isolate the pump. 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.
Protect the pump and pipework from freezing with the addition of suitable 
lagging. The formation of ice may cause serious damage.
