• Before you contact your retailer, please carry out these few simple checks using the following
tables if a problem occurs.
• If the problem persists, contact your retailer.

5.1 I Appliance behaviour
The appliance
does not start
heang straight
away
• When the setpoint temperature is reached, the heat pump stops heang: the water temperature
is higher than or equal to the setpoint temperature.
• When the water ow rate is zero or is not enough, the heat pump stops: check that the water
is circulang correctly in the heat pump (see § “2.2 I Hydraulic connecons”) and that the
hydraulic connecons are correct.
• The heat pump stops when the outdoor temperature falls below -12 °C.
• It may be that the heat pump has detected an operang fault (see § “5.2 I Error code display”).
• If you have checked these points and the problem persists: contact your retailer.
The appliance
is discharging
water
• Oen called condensates, 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
damper the air, the more condensates your heat pump will produce (your appliance may drain
several litres of water per day). This water is recovered at the base of the heat pump and drained
by the condensate drainage elbow (see § “2.2 I Hydraulic connecons”).
• 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 lter pump to circulate water in the heat pump. If the water
connues to ow through the condensate drainage lines, there is a water leak in the heat pump:
contact your retailer.
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 defrost its evaporator, it will stop itself; this means that the
outdoor temperature is too low (below -12 °C).
The appliance is
"smoking"
• The appliance has come to the end of the defrost cycle; water has changed to gaseous state and
passes through the grid.
• If your heat pump is not in its defrost cycle, this is not normal. Switch o and disconnect the
heat pump immediately and contact your retailer.
The appliance is
not working
• When the setpoint temperature is reached, the heat pump stops heang: the water temperature
is higher than or equal to the setpoint temperature.
• When the water ow rate is zero or is not enough, the heat pump stops: check that the water is
circulang correctly in the heat pump (see § “3.2 I User interface presentaon”).
• The heat pump stops when the outdoor temperature falls below -12°C or rises above +40°C.
• It may be that the heat pump has detected an operang fault (see § “5.2 I Error code display”).
The appliance
is working
but the water
temperature
does not
increase
• Check that the automac lling valve is not stuck in open posion; this will keep supplying cold
water into the pool and will prevent the temperature from rising.
• There is too much heat loss: 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 eciency (see § “4.2 I Maintenance”).
• Check that the external environment is not hindering the heat pump (see § “❷ Installaon”).
• Check that the heat pump is the right size for this pool and its environment.
The fan is
running but
the compressor
stops from me
to me with no
error message
• If the outdoor temperature is low, the heat pump performs defrost cycles under normal
operaon.
• The heat pump is unable to capture enough calories as its evaporator is clogged with dirt. Clean
it to restore its performances (see § “4.2 I Maintenance”).
The appliance
trips the circuit
breaker
• Check that the circuit breaker is correctly dimensioned and that the cable secon used is
appropriate (see § “1.2 I Technical specicaons”).
• The supply voltage is too low: contact your electricity supplier.
