Stuart Turner 3.2 bar PS - Manual (Page 3)

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).
The pump is started by a pressure switch and stopped by a flow switch, enabling the unit
to function in both positive or negative head installations.
Before deciding where to position the unit, check to ensure the static inlet head of water
above the pump does not exceed 10 metres (Fig. 3). The static outlet head of water above
the pump must not exceed 13 metres (Fig. 3).
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 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.
