The pump enclosure must be ventilated and there should be a minimum clearance of
80 mm between the pump and housing on all sides.
To prevent loss of pressure through pipework, use pipe size to match pump whenever
possible, minimising 90° bends.
It must be ensured that storage capacity of the liquid supply is adequate for the flow
rates required by the pump.
The pipework feeds to the storage tank should be of adequate size to ensure
replenishment rate of tank is sufficient to meet the needs of the pump.
Isolating valves should be fitted in suction and delivery pipework to enable easy isolation
and access to the pump.
When the pump is to be installed in areas where there is a risk of debris or scale build up
within the system, it is recommended that the inlet pipework is fitted with an inline strainer.
Pump Mounted Above Liquid Source (Suction Lift)
The pumps can be used in a suction lift installation providing the height of lift is within the
limits specified in the limits of application section.
A footvalve and strainer must always be used and the suction pipework size should be
22 mm throughout.
Lay the suction piping over the shortest possible distance and ensure there is a constant
rise from the liquid source to the pump. Any high spots will cause air pockets to form,
reducing system efficiency.
Ensure all joints in suction pipework are completely airtight. Failure to comply will result
in loss of prime.
The intake of the footvalve/strainer should be positioned such that is cannot be blocked
with debris or silt that are frequently found in the bottom of sumps and wells.
When a footvalve is installed on installations that incorporate automatic pump control,
it is recommended that a suitable pressure relief valve be fitted in the discharge (outlet)
pipework from the pump.
ELECTRICAL INSTALLATION
WARNINGS:
 The electrical installation must be carried out in accordance with the
current national electrical regulations by a competent person.
 Before starting work on the electrical installation ensure the power
supply is isolated.
 Where any of the pumps are installed in an area where there is a risk
of water spillage it is recommended that a residual current circuit
breaker having a rated current not exceeding 30 mA, be installed in
the supply circuit. This may be part of a consumer unit or a separate
unit.

This appliance must be earthed.
 The motor and wiring must not be exposed to water.

Do not allow the supply cord to contact hot surfaces, including the
motor shell, pump body or pipework. The cord should be safely
routed and secured by cable clips.
