1 IMPORTANT FACTS:
A Water storage capacity.
1.11
The SPU Mini has a usable water volume of approximately 2 litres; the length
of time the SPU takes to pressurise a system will be dependent on:-
The pressure differential between the cold fill and set pressures and also the
refill rate of the tank
1.12 Ensure the pumps are primed as described in the priming section before
starting, to avoid causing damage to the pump. See Section 6.20 Hydraulic
commissioning.
B Water temperature
This unit is designed to pump cold water only which should not exceed the
following values:
1.13 The maximum allowable water temperature is 23
1.14 The minimum allowable water temperature is 4
C Pipework - General
1.15 Do not drill holes or put fastenings into the SPU Mini tank, this will cause
leakage.
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 the unit. Do not secure pipework to the SPU Mini, this will cause
damage and possible leakage.
1.17 Flux: Solder joints must be completed and flux residues removed prior to SPU
Mini 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
1.20 DO NOT allow contact with oil or cellulose based paints, paint
1.21 DO NOT bend the flexible hose beyond 90
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.
E System filling
1.24 The SPU Mini is NOT DESIGNED TO FILL THE SYSTEM FROM EMPTY.
It is only intended to top up the system after occassional water leakage.
Systems should be filled via a dedicated filling loop.
READ BEFORE COMMENCING PUMP INSTALLATION
DO NOT introduce solder flux to flexible hose, tank, pump or any
parts manufactured from plastic.
