1 IMPORTANT FACTS:
READ BEFORE COMMENCING PUMP INSTALLATION
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
o
C (see Technical Section) .
1 .14 The minimum allowable water temperature is 4
o
C .
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
o
bends .
1 .19
DO NOT introduce solder flux to flexible hose, tank, pump or any
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 bend the flexible hose beyond 90
o
. It must be installed as
detailed,
DO NOT kink . See Installation Section 4 .15 .
D
Plumbing installation regulations
1 .22 The plumbing installation must comply with the current water and building
regulations .
