1 READ BEFORE COMMENCING PUMP INSTALLATION
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
o C.
1.14 The minimum allowable water temperature is 4 o C.
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 o bends.
1.18 DO NOT introduce solder flux to 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 unless pump in suction lift
application.
1.21 DO NOT connect this pump to the mains water supply.
D. Plumbing & Electrical Installation Regulations
1.22 The plumbing installation must comply with “The Water Supply (Water Fittings)
Regulations 1999” and “BS 6700” building regulations.
1.23 The plumbing installation must be installed by a qualified person.
1.24 The electrical installation must be carried out in accordance with the current
