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 position the unit, check to
ensure the static inlet and outlet heads of water above the pump (Table 1), does
not exceed the maximum permitted limits.
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
MUST
be 22 mm (21 mm in ROI).
Pipework should only reduce to 15 mm when entering terminal fitting.
2.19
Static outlet pressure:
The static outlet head must not exceed the values
`
shown in table 1.
2.20
Noise:
The anti-vibration mounting feet and flexible hoses which are 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
.
2.21
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).
2.22
Flexible hoses:
Only use the Stuart Turner hose set supplied with the pump.
2.23
Isolating valves:
Separate system isolating valves (non restrictive) must be
fitted to allow easy pump service.
2.24
Preferred pump location:
The pump must, for optimum performance, be sited
as close as possible to and never more than 4 metres from the HOT WATER
cylinder. The pump should always be sited BELOW the HOT WATER take-off
from the cylinder. The pump location is also dependent on limitations of the
static inlet and outlet heads of the installation. For guidance on limitations and
recommended location, consult the following relevant section for hot or cold
water installation.
