7 Maintenance and service
7.1 Overview: Maintenance and
service
The installer has to perform a yearly maintenance. You can find the
contact/helpdesk number via the user interface.
As end user, you have to:
▪ Keep the area around the unit clean.
▪ Keep the user interface clean with a soft damp cloth. Do NOT use
any detergents.
▪ Regularly check if the water pressure indicated on the gas boiler is
above 1 bar. Switch off the boiler to see the pressure on the main
display of the gas boiler. Ignore the error that appears on the user
interface. When you turn the gas boiler back on, the error will
disappear.
▪ Make sure that electricity and gas prices defined in the user
interface are up-to-date.
Refrigerant
This product contains fluorinated greenhouse gases. Do NOT vent
gases into the atmosphere.
Refrigerant type: R32
Global warming potential (GWP) value: 675
NOTICE
In Europe, the greenhouse gas emissions of the total
refrigerant charge in the system (expressed as tonnes CO
2
equivalent) is used to determine the maintenance intervals.
Follow the applicable legislation.
Formula to calculate the greenhouse gas emissions:
GWP value of the refrigerant × Total refrigerant charge [in
kg] / 1000
Please contact your installer for more information.
WARNING: FLAMMABLE MATERIAL
The refrigerant inside this unit is mildly flammable.
WARNING
The appliance shall be stored in a room without
continuously operating ignition sources (example: open
flames, an operating gas appliance or an operating electric
heater).
WARNING
▪ Do NOT pierce or burn refrigerant cycle parts.
▪ Do NOT use cleaning materials or means to accelerate
the defrosting process other than those recommended
by the manufacturer.
▪ Be aware that the refrigerant inside the system is
odourless.
WARNING
The refrigerant inside the unit is mildly flammable, but
normally does NOT leak. If the refrigerant leaks in the
room and comes in contact with fire from a burner, a
heater, or a cooker, this may result in fire, or the formation
of a harmful gas.
Turn off any combustible heating devices, ventilate the
room, and contact the dealer where you purchased the
unit.
Do NOT use the unit until a service person confirms that
the part from which the refrigerant leaked has been
repaired.

helpdesk number.
8 Troubleshooting
8.1 Symptom: You are feeling too cold
(hot) in your living room
Possible cause Corrective action
The desired room temperature is
too low (high). Increase (decrease) the desired
room temperature.
If the problem recurs daily, do
one of the following:
▪ Increase (decrease) the room
temperature preset value.
▪ Adjust the room temperature
schedule.
The desired room temperature
cannot be reached. Increase the desired leaving
water temperature in accordance
with the heat emitter type.
In case of third-party gas boiler:
The heat pump cannot reach the
desired room temperature, and
the gas boiler is not allowed to
work because of an installer
setting.
Ask your installer to increase the
equilibrium temperature [5‑01].
Note:
▪ When the outdoor temperature
is higher than the equilibrium
temperature [5‑01], the gas
boiler is not allowed to work.
▪ Do not set the equilibrium
temperature [5‑01] too high,
because this would result in
much
less heat pump
operation.
