TYPICAL INSTALLATION (Hot Water, Standard Duty, Single Pump System)
STEP 1 PUMP LOCATION (General)
WARNINGS:
 The pump must not be located where the inlet pressure to the pump is
greater than 10 metres (1 bar).
 Pump Location
If possible 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.
 Care should be taken to protect pump from frost and freezing,
particularly when located in a loft installation.
 The motor casing can become very hot under normal operating
conditions, care should be taken to ensure it cannot be touched during
operation.
The pump must be installed so that the following conditions are met:
Locate the pump in a frost free horizontal position where it cannot be sprayed with water
and as close to the water source as possible, having a minimum flooded suction head of 1
metre at all times. Ensure the water flow is in the direction of the arrow that is marked on
the flow switch reed clamp (vertically upwards).
For the pump to function correctly, it must be installed in a positive head position, a
gravity flow of one litre per minute is required from the highest outlet to operate the built-in
flow switch. This is normally achieved with a static head of 100 mm from base of header
tank to highest position of the shower terminal fitting.
Before deciding where to position the unit, check to ensure the static inlet head of water
above the pump does not exceed the values given in Figs. 2, 3 or 4.
The pump must be installed on its anti-vibration mounting feet and must not be screwed
down.
Typical pump locations are in an airing cupboard, or inside a vanity unit with a small
purpose built dry and ventilated enclosure. The enclosure should have a minimum
clearance of 80 mm (3 “) between the pump and housing on all sides. The enclosure
should be secure and access should only be available by the use of tools.
The plumbing installation must
comply with the following:
The Water Supply (Water Fittings) Regulations 1999.
BS6700 and building regulations.
Be installed by a competent person.
