2 LOCATION - GENERAL
2.11
Access:
For emergencies and maintenance the pump must be
easily
accessible.
2.12
Protection: The pump must be located in a dry position, frost free and
protected from freezing, particularly when installed in a loft (not
recommended).
2.13
Ventilation: Ensure an adequate air flow to cool the pump. Separate
the pump from other appliances that generate heat. An 80 mm (3 “) air
gap must be maintained around the pump.
2.14
Safety:
The motor casing can become very hot under normal
operating conditions. Care must be taken to ensure it cannot be
touched during operation.
2.15
Water
retention:
Site in a location where in the unlikely event of
a water leak, any spillage is contained or routed to avoid electrics
or areas sensitive to water damage.
2.16
Static inlet pressure: Before deciding where to locate the pump check to ensure
the static inlet head (Fig. 2) meets the minimum requirement of 1 metre and does
not exceed the maximum requirement of 5 metres.
2.17
Ambient temperature: The pump must be sited in a location where the maximum
ambient temperature does not exceed 40
o
C.
2.18
Pipework: For optimum performance pipework 28 mm should be used. 22 mm is
acceptable, however, any pipe size reduction will reduce the pumps performance.
2.19
Do not run against a closed valve for periods longer than 5 minutes.
2.20
Portable: The pump is suitable for use as a portable unit and is provided with a
carrying handle for this purpose.
2.21
Pipe size: To prevent loss of pressure through pipework, use pipe size to match
pump (19 mm internal diameter) whenever possible, minimising 90° bends
(sweeping
bends).
2.22
Isolating valves: If permanently installed, isolating valves should be fitted in
suction and delivery pipework to enable easy isolation and access to the pump.
2.23
Inline strainer: When pump is to be installed in areas where there is risk of
debris or scale build up within the system, you
MUST ensure the inlet pipework is
fitted with an inline strainer.
2.24
Suction lift: This pump is capable of a maximum suction lift of 5 m in this case
only, an NRV in the footvalve is permissible (Fig. 3).
