Neglecting to clean the circuit board
and other electronic components in a
dusty environment can lead to a risk of
overheating and ignition.
6 - MAINTENANCE AND
TROUBLESHOOTING
In order to maintain efficiency and improve durability
it is advised that an annual maintenance check be
carried out by a qualified professional.
• Any work on the heat pump must be
carried out by a qualified professional.
• Observe all health and safety rules !
• Any work on the refrigerant circuit must be
carried out by a qualified professional with a
Category 1 certificate of aptitude.
• It is strictly prohibited to release refrigerant gas
into the atmosphere.
The refrigerant must be collected before any
work is carried out on the circuit.
• Switch off the heat pump water heater before
opening it.
• Wait for the fan to come to a complete stop
before starting work on the appliance.
•Do not get water on any of the electrical parts.
• The pressure limiting device must be operated
regularly to eliminate limescale and to check
for blockages.
• Check the condition of the corrosion-proof
anode at minimum once per year.
6.1 - Water circuit / Condensate
draining
To check that the condensates are draining correctly:
- Remove the upper cover (see § «Electrical connections»
procedure).
- Check for blockages in the drainage outlet.
- Clean the condensate recovery trough, where deposits
from the air intake may have gathered.
- Clean the flexible drainage hose.
The pressure limiting device must be switched on regularly to
eliminate limescale and to check for blockages.
Check that all hydraulic connections on the
heat pump water
heater
are watertight.
When draining the tank, ensure that there is a large enough air
inlet at the top to avoid any depression in the tank. The following
materials and products should be avoided:
- Brushes with steel bristles or pads
- Scouring powder
- Any bleach-based product or chlorinated derivative
In case of maintenance or if taking the
heat pump water
heater
out of service, please respect the environmental
protection regulations regarding recovery, recycling and disposal
of consumables and components.
The only maintenance work needed on the air intake circuit is to
clean the evaporator (at least once per year and dependent on
the quality of air intake).
If using air filters check if they are clean regularly. Clean and
replace if necessary.
The fan blades are sharp-edged and may cause injury; take care
not to damage or deform them.
6.2 - Air intake circuit
It is mandatory to periodically inspect for the cleanliness and the
absence of dust deposits on the electronic circuit board and the
electrical terminals:
• of the compressor;
• of the electrical resistance ;
• of the different condensers.
Verify the correct tightness of all lugs. Adapt the frequency
of inspection to the air quality. In a dusty environment more
frequent maintenance and inspection is necessary, at minimum 1
time per year.

The refrigerant circuit containing
flammable refrigerant complies with national
gas regulations.
→
In case of operating on the refrigerant circuit:
1) Secure the area you will be working in
2) Inform people of the potential danger
involved in the work
3) Check that the risk of inflammation is
minimised
4) Avoid working in a confined space; the area
must be sufficiently ventilated
5) Check the area with an appropriate leak
detector before and during the work
6) Place a CO
2
dry powder extinguisher near
the work area
The R290 refrigerant in the heat pump
circuit poses no risk to the environment,
but it is flammable.
→
The R290 refrigerant is odourless.
→
Do not damage the pipes in the refrigerant
circuit.
→
Do not handle a flame or any other flammable
source on the inside of the appliance.
→
If the refrigerant is leaking, unplug the
appliance, air out the room, and contact
customer service.
→
Do not use any mechanical means to speed
up the defrosting process.
→
Do not pierce or burn the appliance: in case
of intervention on the refrigerant circuit, the
refrigerant must be recovered.
