1 IMPORTANT FACTS:

A. Water storage capacity.

1.11 The hot and cold water storage capacity must be sufficient to meet the flow

rates required by the pumped equipment and any other water using fittings and

appliances, which may be operated simultaneously.

1.12 Ensure the pump is primed as described in the priming section before starting,

damage to the shaft seal will result otherwise. See Section 5 - Commissioning.

B. Water temperature

The water entering the pump must be controlled as follows:

1.13 The maximum allowable water temperature is 65

1.14 The minimum allowable water temperature is 4

1.15 DO NOT fit a pump if the hot water is heated via a method whereby the water

temperature cannot be controlled, such as solar or solid fuel you must consult

Bristan.

C. Minimum Flow

1.16 For this pump to operate correctly there must be a minimum gravity flow of at

least 0.8 l/min through the outlet to be pumped.

D. Pipework - General

1.17 Secure pipework: Ensure pipework to and from pump is independently

supported & clipped to prevent forces being transferred to inlet and outlet

branches of pump.

1.18 Flux: Solder joints must be completed and flux residues removed prior to pump

installation (flux damage will void any warranty).

1.19 Pipework design: Care should be taken in the design of pipework runs to

minimize the risk of air locks e.g. use drawn bends rather than 90

1.20 DO NOT introduce solder flux to flexible hoses, pumps or pump parts

manufactured from plastic.

1.21 DO NOT allow contact with oil or cellulose based paints, paint thinners or

strippers, acid based descalents or aggressive cleaning agents.

1.22 DO NOT install a non-return valve, or devices which contain non-return

valves, in the suction (inlet) pipework to the pump. The pump must be

free to vent to the supply tank at all times.

1.23 DO NOT bend the flexible hoses beyond 30

straight as possible.

1.24 DO NOT connect this pump to the mains water supply.

E. Plumbing Installation Regulations

1.25 The plumbing installation must comply with the current water and building

regulations.

1.26 The plumbing installation must be installed by a qualified person.

1.27 The electrical installation must be carried out in accordance with the current

national electrical regulations.

1.28 The electrical installation must be installed by a qualified person.
