1 IMPORTANT FACTS:
A Water storage capacity .
1 .11
The APU Midi has a usable water volume of approximately 8 litres; the length
of time the APU 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 shaft seal . See Section 6 .26 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 APU Midi 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 APU Midi, this will cause
damage and possible leakage .
1 .17 Flux: Solder joints must be completed and flux residues removed prior to APU
Midi 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 hose, tank, pump or any
1 .20 DO NOT allow contact with oil or cellulose based paints, paint
