4.16 Static inlet pressure: Before deciding where to locate the unit check to
ensure the static inlet head between pump and the bottom of the cold tank
(Fig. 2) is at least 1 metre and does not exceed the max inlet head of
10 metres.
4.17 Pump position: The pump must be positioned on its mounting feet and as
close to the water source as possible.
4.18 Ambient temperature: The pump must be sited in a location where the
maximum ambient temperature does not exceed 40
4.19 Pipework: For optimum performance pipework use 28 mm dia., 22 mm can
be used but will result in reduced pump performance. Note: Inlet pipework
must always be greater than or equal to the outlet pipework diameter.
Pipework should only reduce to 15 mm when entering terminal fitting.
4.20 Static outlet pressure: The static outlet head (Fig. 2) must also be within the
maximum requirement of 13 metres.
4.21 Noise: 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.
4.22 Direction of flow: Ensure the water flow is in the direction of the arrow
marked on the flow switch reed clamp (vertically upwards).
4.23 Flexible hoses: Only use the Stuart Turner hose set supplied with the pump.
4.24 Isolating valves: Separate system isolating valves (non restrictive) must be
fitted to allow easy pump service.
4.25 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. Ensure the pump is mounted in a position that allows easy access
to the terminal box if required. The pump location is also dependent on
limitations of the static inlet and outlet heads of the installation.
Access: For emergencies and maintenance the pump must be easily
accessible.
Protection: The pump must be located in a dry position, frost free
and protected from freezing, particularly when installed in a loft
(not recommended).
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.
Safety: The motor casing can become very hot under normal
operating conditions. Care must be taken to ensure it cannot be
touched during operation.
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.
