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 the TechAssist team on +44 (0) 800 31 969 80.
C Pipework - General
1.16 Secure pipework: Ensure pipework to and from pump is independently
supported & clipped to prevent forces being transferred to inlet and outlet
branches of pump.
1.17 Flux: Solder joints must be completed and flux residues removed prior to
pump installation (flux damage will void any warranty).
1.18 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
1.19
DO NOT introduce solder flux to flexible hoses, pumps or pump parts
manufactured from plastic.
1.20 DO NOT allow contact with oil or cellulose based paints, paint thinners
or strippers, acid based descalents or aggressive cleaning agents.
1.21
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.
1.22
DO NOT bend the flexible hoses beyond 30
straight as possible.
1.23
DO NOT connect this pump to the mains water supply.
1.24
DO NOT stress the inlets/outlets of the pump from the misalignment of
hoses/pipework.
D 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.
E Pressure vessel
1.27 Pressure vessel is charged at the factory see Section 6 - Maintenance for
details.
