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 (Figs. 2 & 3) is at least 1

metre and does not exceed the max inlet head of 10 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.

2.18 Ambient temperature: The pump must be sited in a location where the maximum

ambient temperature does not exceed 50

2.19 Pipework: For optimum performance pipework use 28 mm dia., 22 mm can be

used but will result in reduced pump performance.

Pipework should only reduce to 15 mm when entering terminal fitting.

2.20 Static outlet pressure: The static outlet head is indicated in Figs. 2 & 3.

2.21 Direction of flow: Ensure the water flow is in the direction of the arrow marked

on the flow switch reed clamp (vertically upwards).

2.22 Isolating valves: Separate isolating valves (non restrictive) must be fitted to

allow easy pump service.

2.23 Inline strainer: 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.

2.24 Preferred pump location: The preferred pump location is below the water supply

connection that feeds the pump. 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.
