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
MUST
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.
