4.2.3- Piping accessories
4.3 - Hydraulic connections
• A new pressure-relief valve (not included) must be installed and
set to 6 bars on the domestic cold water supply of the appliance.
We would recommend a membrane valve.
The membrane valve system must conform to national and
domestic standards and regulations in eect.
• The pressure-relief valve should be installed as close as possible
to the appliance’s cold water inlet and the water ow should
never be hampered by any accessory (valve, pressure-
reducer, etc...)
• The pressure-relief valve drainage outlet must be installed in a
frost-free place, in a downward-sloping position.
• The pressure-relief valve drainage outlet should be sized
according to building regulations and must never be obstructed.
It should be connected to a vertical draining pipe, using a funnel
which allows an open space of at least 20mm and which is at
least equal in diameter to the appliance’s piping connection.
• If the pressure of the domestic cold water supply is higher than 5
bars, a pressure-reducer should be installed above the pressure-
relief valve near the starting point of the installation (a pressure
of 4-5 bars is recommended).
• It is advised to t a shut-o valve above the pressure-relief valve.
• For installations equipped with:
- piping of a small diameter
- ceramic plate valves
A domestic water expansion vessel, or anti-hammer valves
which are adapted to the installation should be installed as close
as possible to the shut-o valve.
• The following materials should be used for the
The vertical position of the heat pump
water heater must be strictly respected.
If not, there is a risk of condensates
leaking and resulting in a water leak at
the base of the appliance.
• Use the anchoring point at the bottom of the tank to x the
appliance to the oor, using the metal tab (pre-assembled under
the foot) and an ØM8 screw which can be then dowelled into
the ground (see Rep.).

If any of these points have been neglected
or if the water quality did not allow correct
treatment within the legal framework the
warranty will be null and void.
Use of a recirculation pump should be
avoided. Recirculating can cause a lack
of hot water and overconsumption of
energy. If using a recirculation pump, the piping
should be insulated and the pump should be
controlled by a timer or another system which
will prevent domestic hot water from circulating
continuously.
domestic hot water circuit:
- copper
- stainless steel
- brass
- plastic
If the materials used in the domestic hot water
circuit are incompatible, corrosion damage may
occur.
Consequently, the appliance should always be connected to copper
domestic hot water pipes with a cast-iron or steel link, or with
dielectric connections (not supplied) to avoid an iron/copper
galvanic bridge.
• Thoroughly ush the supply line piping before connecting the
appliance to the domestic installation so as not to introduce any
particles, metallic or other, into the appliance.
• Respect the standards in eect in the country of use, notably
hydraulic regulations and pressure safety regulations.
• The appliance must operate with water between 12oF and 30oF.
With particularly hard water (TH>25oF) it is advised to use a water
softener.
• If any of these points have been neglected the warranty will be
null and void (values given are for water at a temperature of
20oC). (See DTU-60-1 for more information).

To access the electrical connections hub:
• Remove the cover and the shell.
• Remove the cover of the appliance by removing the screws which
x the shell onto the lower part of the appliance.
• Remove the black protective cover from the electronics board.
The power supply should comply with all regulations in eect in
the country of installation, as well as the NFC 15-100 standard.
A method of disconnection which ensures total power-cut in
Category III conditions should be installed in xed piping in
compliance with the installation rules.
• an 8A all-pole circuit breaker with a minimum 3mm
contact opening.
• a protective 8A circuit breaker with a 30mA dierential.
If the power supply cable is damaged it must be replaced by the
manufacturer, their customer service technicians, or by a qualied
technician to avoid any risk of injury or danger.
4.5 - Electrical connections
4.5.1 - External control
Only a dry contact, voltage-free, external
connection may be used. Otherwise you
risk damage to the electronics board.
Do not connect the heat pump water
heater to wiring from an older water
heater using the peak/o-peak hours contact.
The heat pump water heater must always be
connected to a power supply.
Peak/o-peak control can be managed through
programming or though an independent cable.
Grounding is obligatory.
Power supply is managed through a 230V single-
phase and grounding cable.
The heat pump water heater can be used to continuously
ventilate a room even if the heating cycle is complete.
To stop the fan from operating, connect a timer on a moisture
sensor. Use the same procedure as for the timer switch, but
connect the 2-wire cable to «Input 2» on the electronics board.
- Switch open = the fan will not operate
- Switch closed = the fan will operate
• Set the regulator to «External control ventilation mode» : fan
mode 3.
4.5.1.2 - Controlled ventilation
4.5.1.1 - Peak/o-peak hours contact
To prevent the electrical back-up from running during peak
hours, connect the dry contact originating from the electricity
counter, to terminal 1.
- Switch open = Back-up not allowed to run
- Switch closed = Back-up allowed to run
By choosing load shedding level 0 or 1 (see § «Load shedding»),
you stop the electrical back-up alone from running (load
shedding =1) or the heat pump and the electrical back-up from
running (load shedding = 0).
• Pass a 0,75mm² 2-wire cable with metal tips through a cable
gland at the back of the appliance and bring the end of the
cable around to the electronics board. The other end of the cable
should be connected to the timer switch.
• Insert the 2-wire cable through a grommet from the electronics
box.
• Connect the 2-wire cable to «Input 1» indicated on the electonics
board, having already removed the existing red bridge.
4.5.1.3 - Electricity provider contact
To program the operation of the heat pump water heater during
peak/o-peak hours, it is not necessary to connect the dry contact
to the electricity counter.
It is possible to program scheduled operating times for the heat
pump water heater or of the electrical back-up from the control
panel (see §3.8 Programming).
It is possible to connect the dry contact from the electricity
counter to the heat pump water heater without programming
from the control panel.
- Switch open = Load shedding
- Switch closed = Normal functioning
The level of load shedding can be chosen from the control panel
of the appliance (see § 5.9.2.4 Load shedding).
By default the electrical resistance does not operate during peak
hours. .
It is not advised to operate the heat

4.5.1.4 - Connection to the photovoltaic function (PV)
This function enables the
appliance to operate in auto-
production mode, which
means that it will use the
energy produced by the PV
function to supply the heat
pump as well as the electrical
back-up, and to heat the water
in the tank.
The connection is made
between the energy manager
electrical box (not supplied)
and connectors 1 and 2 on the electronics board.
• Remove the protective casing.
• Remove the black cover from the electronics board.
• Connect the PV function cable to connector 1 on the electronics board.
• If the PV function regulator has two control contacts, connect them to connectors 1 and
2 on the electronics board. See § « Electrical box electrical diagram » in the appendix. .
• Terminal 1: a low level of electrical energy is produced by the PV function.
• Terminal 2: a high level of electrical energy is produced by the PV function.
Energy manager
dry contact
CAUTION: Connectors 1 and 2 are for DRY CONTACTS ONLY. They must NEVER be connected to 230V.
Deterioration risk: the water tank must be
lled before the appliance is switched on
or connected to a power supply.
5.1 - Control panel
5 - SET-UP AND USE
• Leave the appliance unplugged.
• Open the hot water outlet which is located the highest on the
appliance.
• Open the cold water inlet on the pressure-relief valve.
• Fill the tank until water is coming out of the highest outlet.
• Close the hot water outlet.
Before turning the appliance on, ensure that the entire circuit is
watertight.
The heat pump water heater operates primarily with the
heat pump as long as the air intake temperature remains in
the authorised range from -7°C à +35°C. Outside of this range, the
electrical back-up ensures the heating of domestic hot water.
The temperature of the domestic hot water provided by the heat
pump is adjustable up to 60°C.
In the case of high domestic hot water consumption, the heat
pump water heater has a comfort function, t°C mini which
increases the heating capacity when there is less than 1/3 of
the tank’s volume left at over 38°C (see § «t°c mini -minimum
temperature-»). There is also a setting to activate the electrical
back-up if the heating time is too long (see § « max time»).
If more domestic hot water is required from time to time, the heat
pump water heater has a « boost» function (activated by the user)
which ensures that the water heats to the desired temperature
( for example: 50°C ) quickly with the help of the heat pump and
electrical back-up, This function is deactivated as soon

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 eciency and improve durability
it is advised that an annual maintenance check be
carried out by a qualied professional.
• Any work on the heat pump must be
carried out by a qualied professional.
• Observe all health and safety rules !
• Any work on the refrigerant circuit must be
carried out by a qualied professional with a
Category 1 certicate 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 o 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 exible 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 lters 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 dierent 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.
6.3 - Electrical maintenance
