11.0 WINTERISATION PROCEDURE
WARNING
Isolate machine before opening! As heat pump embodies electrical and rotational equipment, it is recommended for your own safety that a
competent person carries out the following procedure.
Drain Down Procedure
ALL MODELS
Object
To provide frost protection
To eliminate corrosion problems
To inhibit electrical components
1.
Switch off electrical supply to heat pump.
2.
Remove external fuses and keep in safe place away from heat pump to
prevent accidental operation of heat pump.
3.
Ensure water circulation pump is switched off.
4.
Drain water from heat pump by:
a) drain valve if fitted.
b) disconnecting pipework to and from heat pump.
c) Note that where there is more than one condenser there will be
multiple drain down points, all of which need to be opened.
d) On PPT70, PPT90BMY and PPT140 drain condensers by
removing drain down cap.
Refer to installation drawings. (Replace cap when this has been
done).
N.B. If this procedure is not adopted and frost or corrosion damage results then the warranty will become invalid.
11.1 START UP PROCEDURE AFTER WINTERISATION
1.
Replace covers (if not fitted).
2.
Remove front grille — using softbrush clean finned surfaces of heat pump.
Replace panel.
3.
Remove plastic covers on water connections and reconnect water piping
or close drain valve.
4.
Start up water circulating pump and leave running for at least 1/4 hour to
establish flow and enable any air in system to escape.
5.
Replace fuses to heat pump circuit.
6.
Switch on heat pump.
ANY SIGNIFICANT PERIODS OF NON USE NEED TO BE RECORDED ON THE MACHINE RECORD LOG ON PAGE 51
SD566252 ISSUE 51
5.
Flush through water circuit in heat pump by using CLEAN TAP WATER
(NOT POOL WATER) via hose into outlet connection – run for 10 minutes
minimum; use spray nozzle if available.
6.
Allow to drain – fit plastic bags secured by elastic bands over water
connections.
7.
Uncover electrical enclosure (see page 11 fig.4) and liberally spray interior
of unit, with moisture repellant aerosol WD-40 or similar, reseal enclosure.
8.
If heat pump located outside, protect from weather by covering with
VENTILATED cover. Do not use plastic sheet as condensation can occur
within unit.
7.
Check control thermostat is set to required pool temperature.
8.
Check daily to ensure pool water is at the correct pH and has the correct
chemical balance. See section 3 Plumbing.
Note that the compressor will not start until after a delay of 12 hours. This
allows time for the compressor to warm up and prevents damage to the
refrigeration circuit.
