GENERAL
1.1. Access: For emergencies and maintenance the pump must be easily accessible.
1.2. Protection: The pump must be located in a dry position, frost free and
protected from freezing, particularly when installed in a loft (not
recommended). The pump must be protected from the elements.
1.3. Ventilation: Ensure an adequate air flow to cool the pump. Separate the pump
from other appliances that generate heat. An 80mm (3“) air gap must be
maintained around the pump.
1.4. Safety: The motor casing can become very hot under normal operating
conditions. Care must be taken to ensure it cannot be touched during
operation.
1.5. 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.
1.6. 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 (Ref
Fig. 2) does not exceed the max inlet head of 10 metres.
1.7. Ambient temperature: The pump must be sited in a location where the
maximum ambient temperature does not exceed 40°C.
1.8. Pipework: For optimum performance pipework use 22mm diameter.
1.9. Fixing: Ensure the pump is adequately secure when installed.
Note: Inlet pipework must always be greater than or equal to the outlet pipework
diameter. Pipework should only reduce to 15mm when entering terminal fitting.
When the length of the inlet pipe is more than 10 meters or the height of the inlet
pipe is greater than 4 meters, the diameter of the inlet pipe must be larger than the
diameter of the outlet.
1.10. Static outlet pressure: The static outlet head (Fig 2) must also be within the
maximum requirement of 12 metres.
1.11. Noise: Care must be taken when mounting the pump so that noise is not
amplified through loose panels or pipework.
1.12. Direction of flow: Ensure water enters the pump via the inlet on the front of the
pump and exit out the top.
1.13. Flexible hoses: Only use the Stuart Turner hose set that are available for the
pump.
1.14. Isolating valves: Separate system isolating valves (non-restrictive) must be
fitted to allow easy pump service.
