LOCATION - GENERAL
•
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.
•
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 water tank (Figure 4 and Figure 5), is at least
0.5 metres and does not exceed the max inlet head of 10 metres
or 13 metres depending on the model (See Sections 10 and 11 –
Technical Specifications).
•
Ambient temperature
: The pump must be sited in a location
where the maximum ambient temperature does not exceed
40 °C.
•
Pipework
: For optimum performance pipework
MUST
be 22 mm.
Pipework should only reduce to 15 mm when entering terminal
fitting.
•
Noise
: If supplied the anti-vibration mounting feet and flexible
hoses can be used 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
.
•
Direction of flow
: Ensure the water flow is in the direction of the
arrow that is marked on the flow switch reed clamp (vertically
upwards).
•
Flexible hoses
: Only use the Bristan hose set supplied with the
pump.
•
Isolating valves
: Separate system isolating valves (non restrictive)
must
be fitted to allow easy pump service.
•
Inline strainer:
You
MUST
ensure the inlet pipework is fitted with
an inline strainer.
