1 IMPORTANT FACTS:
A Water storage capacity.
1.11
The 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 4 –
Commissioning.
B Water temperature
The water entering the pump must be controlled as follows:
1.13 The maximum allowable water temperature is 35
1.14 The minimum allowable water temperature is 4
C Pipework – General
1.15 Secure pipework: Ensure pipework to and from pump is independently
supported & clipped to prevent forces being transferred to inlet and outlet
branches of pump.
1.16 Flux: Solder joints must be completed and flux residues removed prior to
pump installation (flux damage will void any warranty).
1.17 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
1.18
DO NOT introduce solder flux to flexible hoses, pumps or pump parts
manufactured from plastic.
1.19
DO NOT allow contact with oil or cellulose based paints, paint thinners
or strippers, acid based descalents or aggressive cleaning agents.
1.20 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. Exceptions can be
made in the case of suction lift installations when a footvalve is
required.
1.21
DO NOT connect this pump to the mains water supply.
D Plumbing Installation Regulations
1.22 The plumbing installation must comply with the current water and building
regulations.
1.23 The plumbing installation must be installed by a qualified person.
