❹ Troubleshooti ng
• Before you contact your reseller, please carry out these few simple checks using the following
tables if a problem occurs.
• If the problem conti nues contact your reseller.

4.1 I Device behaviour
The device does
not start heati ng
straight away
•
On start-up, the device remains "paused" for 3 minutes before it starts operati ng.
•
When the setpoint temperature is reached, the heat pump stops heati ng: the water temperature
is higher than or equal to the setpoint temperature.
•
When the water fl ow rate is zero or is not enough, the heat pump stops: check that the water
is circulati ng correctly in the heat pump (see § “2.5 I Presentati on of the menu”) and that the
hydraulic connecti ons are correct.
•
The heat pump stops when the outside temperature drops below 5 °C for standard models or
-8 °C for reversible models.
•
It may be that the heat pump has detected an operati ng fault (see § “4.2 I Error code display”).
•
If you have checked these points and the problem persists: contact your reseller.
The device is
draining water
•
Oft en called condensati on. This water is the moisture contained in the air which condenses
on contact with certain cold mechanisms in the heat pump, especially on the evaporator. The
more damp the air, the more condensati on your heat pump will produce (your device may drain
several litres of water per day). This water is retrieved by the base of the heat pump and drained
through the holes.
•
To check that the water is not coming from a leak in the pool circuit on the heat pump, shut
down the heat pump and run the fi ltrati on pump for the water to circulate in the heat pump. If
the water conti nues to fl ow through the condensati on drains, there is a water leak in the heat
pump; contact your reseller.
The evaporator is
iced over
•
Your heat pump will soon switch to its defrost cycle to melt the ice.
•
If your heat pump cannot manage to deice its evaporator, it will stop itself; this means that the
outdoor temperature is too low (below -5 °C for standard models, -8°C for reversible models).
The device is
"smoking"
• This may occur when it is in a defrost cycle and the water is converted to gas.
•
If your heat pump is not in its defrost cycle, this is not normal. Switch off and disconnect the
heat pump immediately and contact your reseller.
The device is not
working
•
If there is no display, check the supply voltage and the F1 fuse.
•
When the setpoint temperature is reached, the heat pump stops heati ng: the water temperature
is higher than or equal to the setpoint temperature.
•
When the water fl ow rate is zero or is not enough, the heat pump stops: check that the water is
circulati ng correctly in the heat pump (see § “2.5 I Presentati on of the menu”).
•
The heat pump stops when the outside temperature drops below 5 °C for standard models or
-8 °C for reversible models.
•
It may be that the heat pump has detected an operati ng fault (see § “4.2 I Error code display”).
The device is
working but
the water
temperature
does not increase
•
It may be that the heat pump has detected an operati ng fault (see § “4.2 I Error code display”).
•
Check that the automati c fi lling valve is not stuck in open positi on; this will keep supplying cold
water into the pool and will prevent the temperature from rising.
• There is too much heat loss as the air is cool. Install a heat insulated cover on your pool.
•
The heat pump is unable to capture enough calories as its evaporator is clogged with dirt. Clean
it to restore its performances (see § “3.2 I Maintenance”).
•
Check that the external environment is not hindering the heat pump (see § “❶ Installati on”).
•
Check that the heat pump is the right size for this pool and its environment.
The venti lator
is running but
the compressor
stops from ti me
to ti me with no
error message
• If the outdoor temperature is low, the heat pump will perform defrost cycles.
•
The heat pump is unable to capture enough calories as its evaporator is clogged with dirt. Clean
it to restore its performances (see § “3.2 I Maintenance”).
The device
trips the circuit
breaker
•
Check that the circuit breaker is correctly dimensioned and that the cable secti on used is
the right one (see § “5.2 I Technical specifi cati ons”).
•
The supply voltage is too low; contact your electricity supplier.
•
On the Z300 M5, MD5, M7, PM3051, PM3052, PM3061, EverFirst 11M, 11MD and 13M models,
the voltage may drop when the compressor starts; install a progressive starter.
•
The VA varistor(s) may be damaged; replace them.
