Calorex Pro-Pac 45 - WINTERISATION PROCEDURE; START UP PROCEDURE AFTER WINTERISATION

11.1 START UP PROCEDURE AFTER WINTERISATION
1. Replace covers (if not fitted).
2. Remove front grille — using sobrush 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.
7. Check control ermostat is set to required pool temperature.
8. Check daily to ensure pool water is at e correct pH and has e correct
chemical balance. See section 3 Plumbing.
Note at e compressor will not start until aer a delay of 12 hours. This
allows time for e compressor to warm up and prevents damage to e
refrigeration circuit.
11.0 WINTERISATION PROCEDURE
WARNING
Isolate machine before opening! As heat pump embodies electrical and rotational equipment, it is recommended for your own safety at a
competent person carries out e 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 at where ere is more an one condenser ere 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 is has been
done).
5. Flush rough 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, wi moisture repellant aerosol WD-40 or similar, reseal enclosure.
8. If heat pump located outside, protect from weaer by covering wi
VENTILATED cover. Do not use plastic sheet as condensation can occur
wiin unit.
N.B. If is procedure is not adopted and frost or corrosion damage results en e warranty will become invalid.
