Contact your reseller or a qualified technician
High pressure
fault
• Water and air mixture passing
in the appliance,
• Unsatisfactory water flow,
• Blocked flow controller
• Clogged or blocked heat
exchanger
• Water temperature too high
(32°C maximum)
• Check the pool hydraulic circuit
• Increase the flow-rate using the by-pass, check
that the pool filter is not clogged)
• Check the flow-rate controller
• Clean the exchanger
• If the defect persists, contact an approved
technician
• Wait for the temperature to drop

• Air temperature too low
• The ventilator is out of order
• The evaporator is dirty
• Wrong value provided by the
air or deicing sensor
• Wait for the temperature to come within the
operating range
• Contact your reseller or a qualified technician

5.2 Appliance malfunctions
Malfunction
Possible causes
Solutions
The appliance is out
of order
• No display
• The pool temperature is above the
set point temperature
• There is a message on the screen
• Water flow absent or incorrect
• The air temperature is too low
• Check the power supply voltage and fuse F1
• Increase the set point temperature
• Check the meaning of the message in §5.1
• Check the water flow (by-pass, filtering)
• Wait until the air temperature returns to within the
operating range
The appliance is
working but the
water temperature
does not rise
• Insufficient filtering time
• Usage period not compliant
• The heat pump is undersized
• The automatic pool filling is blocked
in the open position
• The heat insulated cover is not used
• The evaporator is dirty
• The appliance is incorrectly located
• There is a message on the screen
• Switch the filtering to manual 24h/24 for the
temperature rise
• Check that the outside temperature is compliant
with the operating range (see §1.3)
• Check the heat pump specifications for the pool
• Check that automatic filling is in working order
• Position the heat insulated cover
• Clean the evaporator (see §4.1)
• The appliance must be installed outside.
• Check that there are no obstacles at less than 3
metres from the blower, and 0.50 metres behind
the heat pump (see §2)
• Check the meaning of the message §5.1
The ventilator is
running but the
compressor stops
from time to time
without any error
messages
• The heat pump occasionally performs
defrosting cycles
• The evaporator is dirty
• Normal if the outside temperature is less than 12°C
• Clean the evaporator
The heat pump is
tripping the circuit
breaker
• The circuit breaker is incorrectly or
wrongly sized
• The cable size is undersized
• The supply voltage is too low
• Check the circuit breaker (see § 2.4.3)
• Check the cable size (see §2.4.3)
• Contact your electricity supplier
