Checking; Overwintering - Zodiac PF 11M Installation Instructions Manual

 switch on the electrical supply to the heat pump,
When the regulator is first switched on, the following information messages appear: "REXX"
then "MAPX".
 if the heat pump is in stand-by:
seconds and then the water temperature is displayed.

=> If the pool requires heating, the indicator
heat pump compressor + fan start up at the same time.
 during the first 5 minutes of compressor and fan operation, the 3 coloured bars located left of the
display blink
through the heat pump is: too low
(red bar).
 if the regulator detects that the flow-rate is too low or too high, valve 5 (or 3 if 5 is not present)
must be adjusted until the green middle bar lights up.
During this adjustment phase, wait 30 seconds after each valve position change as the
regulator response time is not instantaneous.
Once the pool has attained the required temperature, the heat pump switches off
automatically (indicators
 in case of mains power failure, when the power supply is restored, the heat pump starts up after a
time period of 2 minutes.
 when the ambient temperature is between 5 and 12 °C, the heat pump may start a defrost cycle
(indicators and
defrost the evaporator with the ambient air. Once the end of defrost cycle has been detected, The
compressor and fan restart after a time period of 2 to 5 minutes (varies according to the compressor
stoppage time).

1.5.4 Checking

The heat pump must switch off when filtering is stopped or valve 2 (or 4 if present) is closed.

1.5.5 Overwintering

Wintering is essential, on pain of the condenser freezing, and this case is not covered
by the warranty.
 switch the regulator to "stand-by" mode by pressing and holding for 3 seconds on
then appears on the screen for 5 seconds before a small red dot appears
If the indicator
With the priority heating function connected, the filter remains on for 2 minutes, after switching
the heat pump to "stand-by" (outside the programmed filter periods).
If a heat pump defrost cycle is in progress: the fan remains on until the end of this
cycle.
 open the valve 1,
 close valves 2 and 3, and open valves 4 and 5 (if present),
 ensure that no water is flowing through the heat pump,
 drain the water condenser (risk of freezing) by removing the two pool water inlet and outlet
connections at the back of the heat pump,
 in the case of a full winterizing of the pool: connect the inlet and outlet connections "lightly" without
tightening (one turn) in order to avoid foreign bodies entering into the condenser,
 in the case of winterizing the heat pump alone: do not reconnect the inlet and outlet connectors,
instead place two stops (supplied) on the condenser water inlet and outlet.
 cover the heat pump with a micro-breathing overwintering cover (optional accessory, see §3.2).
To avoid damaging the appliance with condensation, do not cover it hermetically.
