5.3 - 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 vertical position of the domestic
hot water heat pump 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.
• The oor must be able to support the weight of the domestic hot
water heat pump (weight of the domestic hot water heat pump
lled with water 250 L= 335 kg).
5.2- Air connection
The appliance is designed for use with indoor air.
It can be ducted to indoor air, provided the following requirements
are met :
- Air temperature between 5°C and 35°C;
- Ø160mm insulated duct;
- Total length of duct < 6 metres round trip
(with one elbow = one metre).
Failure to comply with these recommendations will invalidate the
manufacturer’s warranty.
Mounted without a duct, the device must be installed in a room not
heated (minimum 20m3) isolated from neighboring heated rooms.
• If the free height under the ceiling is less than 60cm above the water
heater, it is recommended to install an elbow at the air outlet and
orient it to the rear or to the sides.
• The thermodynamic water heater allows the recovery of the heat
coming from the ground of an unheated, semi-buried room such
as than the workchop or the garage.
• The thermodynamic water heater allows dehumidication and
cooling of rooms such as laundry rooms or cellars.
It is forbidden to duct the appliance to
outside air!
• The following materials should be used for the
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 flush 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 maximum temperature of domestic hot water at the tap points
must never exceed 50°C for the toilet and 60°C for other uses. Install
adequate thermostatic mixers to avoid burn hazards.
• 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).

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.
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.

5.4 - Condensates drainage
The cooling of the air circulating in the evaporator can lead to the formation of condensate, the quantity of which varies according to the level
of humidity in the air.
Condensate must be evacuated via a drain pipe at the rear of the appliance to a waste water drain.
To ensure correct drainage, the following points must be observed:
• Drainage must be via a siphon (the hose must not be used as a siphon) to the waste water system ;
• Fill the siphon with water ;
• The drain pipe must be immersed in the water in the siphon ;
• A minimum 3° slope must be maintained ;
• It is forbidden to bend the hose ;
• Do not connect to a nipple.
The siphon is essential, as if it is connected directly to the waste water, rising sewage can damage the
appliance’s refrigeration circuit!

• 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 domestic hot water heat pump operates primarily with the
heat pump as long as the air intake temperature remains in the
authorised range from +5°C à +35°C. Outside of this range, the
electrical back-up ensures the heating of domestic hot water.
Deterioration risk: the water tank must
be lled before the appliance is switched
on or connected to a power supply.
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 domestic
hot water heat pump has a comfort function,
p
which increases
the heating capacity when there is less than 1/3 of the tank’s volume
left at over 38°C.
If more domestic hot water is required from time to time, the
domestic hot water heat pump 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 as the
required temperature is reached (
for example: 50°C ).
From time to time, check that there are no alerts (in case of an alert,
please refer to § «Error messages»).

7.1 - 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 domestic hot water
heat pump are watertight.
If the corrosion-proof anode is in a poor
state of repair it will shorten the lifespan
of the appliance and render the warranty
null and void.
The primary corrosion-proof anode ensures the protection of the
tank, it must be inspected at regular intervals (at minimum once per
year) after the initial set-up of the domestic hot water heat pump.
Check the magnesium anode by measuring the current:
• Disconnect the anode cable from the earth terminal.
• Measure the current between the anode cable and the earth
terminal.
If the current is greater than 0.3mA, the anode is operational; if the current is less than 0.3mA, visually check the anode:
- Remove the plastic cover.
- Partially drain the appliance below the height of the anode.
- Remove the anode.
- Check the diameter of the anode at the narrowest point. This diameter must be greater than 15mm (the initial diameter of the anode
being 33mm).
- If the diameter is less than 15mm, replace the anode.
- Remove any deposits from the thread.
- Ret the anode.
- Rewire the anode.
- Ret the plastic cover.

7.4 - Drainage
When draining the tank, ensure that there is a sucient air intake at
a high point of the tank so as to avoid any depressions in the tank.
Materials and products to avoid:
- brushes with steel bristles and steel wool pads
- scouring powder
- all bleach based or chloride products
1) Switch o the power supply.
2) Shut o the cold water inlet valve on the safety group and ensure
there is an air intake valve on a high point of the appliance.
3) Open the hot water valves.
4) Set the safety group to the drainage position.
7.5 - Modication
Any modication of the appliance is prohibited. Any replacement
of components must be done by a professional with original parts
from the manufacturer.
7.6 - Decommissioning
In the event of a prolonged absence with the power supply to the
housing and the product disconnected, ask a qualied professional
to drain the product or protect it from freezing.
Under no circumstances should potential ignition sources be used
for the detection or detection of refrigerant leaks. A halogen are
(or other detector using an open ame) shall not be used.
• Electronic leak detectors may be used to detect refrigerant leaks,
but for ammable refrigerants, sensitivity may not be adequate or
may require recalibration.
• Ensure that the detector is not a potential ignition source and is
suitable for the refrigerant used. Leak detection equipment must be
set to a percentage of the lower ammability limit of the refrigerant
and must be calibrated for the refrigerant used. The value of 25%
of the lower ammable limit is used as the maximum.
• Liquid leak detectors are also suitable for use with most refrigerants
but the use of chlorine-containing detergents should be avoided
as chlorine can react with the refrigerant and corrode copper from
the piping.
• If a leak is suspected, all open flames must be suppressed /
extinguished.
7.6.1 - Leak detection
• When opening the refrigeration circuit to perform repairs - or for
any other purpose - conventional procedures must be used.
• For ammable refrigerants, it is important to use best practice as
ammability must be considered.
• The following procedure must be followed :
- Remove the refrigerant ;
- Purge the circuit with inert gas ;
- Evacuate to the atmosphere;
- Purge with inert gas ;
- Open the circuit by cutting or brazing.
• Refrigerant must be recovered in a suitable recovery bottle.
• The system must be purged with nitrogen without oxygen.
• This process may need to be repeated several times. Compressed
air or oxygen should not be used to purge refrigerant systems.
• The purge of refrigerants must be performed by breaking the
vacuum in the system with nitrogen without oxygen: By lling
up until the working pressure is reached, an evacuation to the
atmosphere, and nally by vacuum pulling.
• This process must be repeated until there is no more refrigerant
in the circuit.
• When the last oxygen-free nitrogen charge is used, the circuit must
be brought to atmospheric pressure to allow intervention.
• Ensure that the vacuum pump outlet is not near potential ignition
sources and that ventilation is available.
7.6.2 - Removal and evacuation
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.
7.2 - Air intake circuit
Neglecting to clean the circuit board and
other electronic components in a dusty
environment can lead to a risk of overheating
and ignition.
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.
• Check that the wiring is not subject to wear, corrosion, excessive
pressure, vibration, contact with sharp edges or any other adverse
eects due to its environment.
• Maintenance must also take into account the eects of long-term
continuous vibration from components such as the compressor
and fan.
7.3 - Electrical maintenance

When transferring refrigerant into the recovery bottles, ensure that
only the appropriate bottles are used. Make sure you have enough
bottles to recover the entire system load. All cylinders used are
dedicated to the refrigerant recovered and labeled for it (i.e., special
cylinders for refrigerant recovery). Cylinders must be complete with
pressure relief valve, associated shut-o valves and in good working
condition. Empty recovery cylinders are evacuated and, if possible,
cooled prior to recovery.
• Recovery equipment must be in good working order with all
instructions at hand and must be suitable for recovery of all
refrigerants including, where applicable, ammable refrigerants.
In addition, a set of calibrated scales must be available and in good
working order.
• Hoses must be complete with leak-free disconnects and in good
condition. Before using the recovery machine, verify that it is in
good working order, has been properly maintained and that all
associated electrical components are sealed to prevent ignition in
the event of a refrigerant leak. Consult the manufacturer if in doubt.
• The recovered refrigerant must be returned to the supplier in the
appropriate recovery bottle and the transfer note lled in correctly.
Do not mix refrigerants in recovery units and especially not in
recovery bottles.
• If compressors or compressor oils need to be replaced, make sure
they have been vacuum pulled to an acceptable level to ensure
they are not left in the ammable refrigerant lubricant. Vacuum
pulling must be done before the compressor is returned to the
supplier. Only electric heating of the compressor body should be
used to accelerate this process. When oil is drained from a system,
it must be done safely.
7.6.5 - Recovery
• The product must be labelled indicating that it has been taken out
of service and emptied of the refrigerant.
• The label must be dated and signed.
• Ensure that there are labels on the product indicating that it
contains a ammable refrigerant.
Entrust the disposal of the packaging to the installer who installed
the product.
The above symbol requires:
- Do not dispose of the product with the household waste.
- Dispose of the product at a collection point for used electrical
and electronic equipment.
7.7.6 - Recycling and Disposal
• Ensure that contamination of dierent refrigerants does not occur
when using charging equipment. Hoses or lines should be as short
as possible to minimize the amount of refrigerant they contain.
• Cylinders must be held in an appropriate position according to
instructions.
• Make sure the refrigeration system is grounded before charging
the system with refrigerant.
• Label the system when the load is complete (if not already done).
• Extreme precautions must be taken to not overload the
refrigeration system.
• Before recharging the system, it must be pressure tested with the
appropriate purge gas.
• The system must undergo a leak test at the end of the load but
before commissioning. Another follow-up leak test must be
performed before leaving the site.
7.6.3 - Charging process
• Before performing this procedure, it is essential that the technician
knows the product and all its specicities.
• It is recommended to use best practices to ensure that all
refrigerants are safely recovered. Before the task is performed,
an oil and refrigerant sample must be taken in case an analysis is
required before recycling the recovered refrigerant. It is essential
that a power supply is available before the intervention begins.
a) Familiarize yourself with the product and how it works
b) Electrically isolate the system.
c) Before attempting the procedure, ensure that:
- mechanical handling equipment is diponible, if necessary, for the
handling of refrigerant cylinders ;
- all personal protective equipment is available and used correctly ;
- the recovery process is being overridden at all times by a competent
person.
- recovery equipment and cylinders comply with appropriate
standards.
d) Perform a «pump down» on the appliance where possible.
e) If it is not possible to vacuum, make a manifold so that the
refrigerant can be removed from various parts of the system.
f) Make sure the recovery bottle is on the scale before the start of
uid recovery.
g) Start the recovery group and operate it according to the
instructions.
h) Do not overll bottles (no more than 80% in volume of liquid
charge).
i) Do not exceed the maximum operating pressure of the cylinder,
even temporarily.
j) Once the cylinders have been lled correctly and the process
completed, ensure that the cylinders and product are removed
from the site quickly and that all isolation valves on the product(s)
are closed.
k) Refrigerant must not be loaded into another refrigeration system
unless cleaned and veried.
