Pump Location - Stuart Turner Showermate Series Installation Instructions Manual

STEP 1 PUMP LOCATION (General)
WARNINGS:
The pump must not be located where the static inlet pressure to the
pump is greater than permitted.

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 loft position.
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 dry, frost free position where it cannot be sprayed with water. It
should be positioned horizontally on its anti-vibration mounting feet and should not be
screwed down. It should be positioned as close to the water source as possible, having a
minimum flooded suction head of 0.5 metres at all times.
Ensure the water flow is in the direction of the arrow that is marked on the flow switch
module casing (vertically upwards).
For the pump to function correctly, it must be installed in a positive head position, a
gravity flow of approx. 0.8 litres 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. 5, 6, 7 or 8.
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 resilient anti-vibration mounting feet and flexible hoses which are supplied as
standard, are a precaution to reduce noise transmission, however care must be taken
when mounting the pump that any noise is not amplified through loose panels, pipework
or other mounting medium.
The preferred pump location is at floor level next to the hot water cylinder or a level that
is below the secondary tapping that feeds the pump. This will ensure the pump has
access to an air free water supply which is important for trouble free operation (Fig. 5 for
Twins and Fig. 6 for Singles).
