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 the pump 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 unit check to ensure
the static inlet head between pump and cold water level (Fig. 2) is at least 1 metre
and does not exceed the max inlet head of 5 metres.
2.17 Pump position: The pump must be positioned on its anti-vibration mounting feet
and as close to the water source as possible. The pump has a side mounted
terminal box. Ensure the pump is mounted in a position that allows easy access
to the box if required.
2.18 Ambient temperature: The pump must be sited in a location where the maximum
ambient temperature does not exceed 40 o C.
2.19 Pipework: For optimum performance pipework 28 mm should be used. 22 mm is
acceptable, however, any pipe size reduction will reduce the pumps performance.
2.20 Static outlet pressure: The static outlet head (Fig. 2) must also be within the
maximum requirement of 13 metres.
2.21 Noise: The anti-vibration mounting feet and flexible hoses have been supplied
as standard, and a precaution to reduce noise transmission, however care must
be taken when mounting the pump that any noise is not amplified through loose
panels or pipework. Do not screw down the pump.
2.22 Direction of flow: Ensure the water flow is in the direction of the arrow marked
on the flow switch reed clamp (vertically upwards).
2.23 Isolating valves: If permanently installed, isolating valves should be fitted in
suction and delivery pipework to enable easy isolation and access to the pump.
2.24 Inline stainer: 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.
2.25 Preferred pump location: The preferred pump location is at floor level next to
the water source or a level that is below the secondary tapping that feeds
the pump. The pump location is also dependent on limitations of the static inlet
and outlet heads of the installation.
