INSTALLATION

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

must be conducted by designated, qualified and competent personnel.

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.
