Installation must be carried out in accordance with these instructions, and

Pump Location
1.
The preferred pump location is at floor level next to the hot water cylinder
or a level that is below the tapping that feeds the pump. This will ensure
access to an air free water supply which is important for the pump to
operate reliably. (See Fig. 2.)
2.
The pump must NOT be located where the static inlet pressure is
greater than permitted and within the values given. (See Fig 3 & 4 and
'SPECIFICATIONS' or rating label attached to the pump.)
3.
Water pumps can develop leaks and should, therefore, not be located
where seepage may go undetected or cause damage. The pump must
be installed such that it is accessible for servicing or removal. When
servicing or disconnecting, small amounts of water may drain from the
unit and pipework.
4.
To allow servicing of this product 4 x full bore servicing valves MUST
be fitted close to the flexible connections on the inlets and outlets
5.
Take care to protect the pump from frost and freezing, particularly when
located in an unheated area.
6.
Make sure adequate ventilation is provided (minimum clearance of
80 mm around all sides of the pump). The pump should be installed in
a low dust area.
