2.1 Dimensions
2.2 - Placement
2.2.1 - Air Intake
2.2.2 - Positioning
To be considered when choosing the final placement:
• D.W.H.P must not be installed outdoor
• D.W.H.P must be installed in a room outdoor from frost. Also, the temperature of the air taken in must
range between -5°C and 35°C. When the temperature is below -5°C or above 35°C, the water is no
longer heated by the heat pump, but by the electrical backup.
• inlate air must be clear of any pollution, and dust.
• The air taken in must not originate from a heated room.
• The device must not be placed in a room which risks explosion due to gases, vapours or dust and
must not intake air from rooms with the same risks.
• The floor must be able to support the weight of the device (weight of D.W.H.P when full = approx.440kg)
• Position D.W.H.P and adjust the stands in such a way that it is level. A slight inclination to the right of
the device (1° max.) is acceptable.

2.5 - Plumbing connections
• It is mandatory to install a new pressure-relief valve (not included) set to 7 bars on the domestic cold water
supply of the device. Membrane type valve are recommended.
This pressure-relief valve must conform to the domestic standard.
• The pressure-relief valve must be installed as close as possible to the cold water inlet of the device and the
passage of water must never be hindered by any accessory (valve, pressure controller, etc...)
• The drain outlet of the pressure-relief valve must be sized following the requirements of construction
standard and must never be blocked. It must be connected by use of a funnel, allowing a minimum
20mm open space, to a vertical draining pipe of a diameter equal to the piping connection of the device.
• The drain outlet of the pressure-relief valve must be installed in a frost-free place and pointing downward.
• If the pressure of the domestic cold water supply is higher than 5 bars, install a pressure reducer above the
pressure-relief valve at the beginning of the installation (a pressure of 4 to 5 bars is recommended).
• It is advised to install a shut-off valve above the pressure-relief valve.
• In cases of installations equipped with
- piping of a small diameter
- ceramic plate valves
it is necessary to install, as close as possible to the shut-off valves, a domestic expansion vessel adapted to
the installation.
• For the domestic hot water circuit, use the following materials:
- copper
- galvanised steel
- brass
Depending on materials used in the hot water circuit, incompatibilities could result in damage due
to corrosion.

In consequence, the connection of the device to the copper piping of the domestic hot water should
ALWAYS be carried out via a cast iron fitting, or steel, or with the help of dielectric connections (not
included) which will help to avoid any iron/copper galvanic bridge.
• Rinse the supply line piping before attaching it to the domestic installation of the device in order to avoid
the introduction of any particles, metallic or other.
• Respect the current standard in the country of use,notably those that concern domestic and pressure safety
conditions.
• The maximum temperature of the domestic hot water at delivering points should never surpass 50°C for the
toilet and 60°C for other uses. Install thermostatic mixing valves adequate enough to avoid any burn risks.
• In regions where the water contains high levels of limestone (TH > 20°F), it is recommended to treat water
with a softener. Softened water should conform to the criteria defined by the country’s norms.
• In all cases, softened or not, the latter should conform to the country’s hot water additional clause norms
concerning:
- chloride levels
- resistivity (between 2200 and 4500 ohm/cm)
- 12°F < TH < 30°F
- …
The warranty does not apply if these points are neglected or if the water
quality did not allow the correct treatment in the legal framework.
N.B. :
• Domestic hot water cycling loop: in order to save energy,it is recommended not to use domestic
hot water recycling.When a recycling line is attached to the hot water distribution systen, foresee
the possibility of a shut-off mechanism (valve or faucet) in order to limit useless energy loss. The
connection of the recycling line is carried out in funtion of need (with a timing command).

2.7.2 Ventilation controled
D.W.H.P can be used to permanently ventilate a room . This ventilation can be used to renew the air. In this case,
the connection of a humidity sensor (entry 2) allows to activate the operation of the ventilator in function to the
ambiant humidity. In all cases, the ventilator always operates with the heat pump.
• swith open = the ventilator does not operate
• switch closed = the ventilator operates
Set the regulator to mode “Ventilation with external control” (“PAR.05” set to mode 3 – see section “PAR.05
– Ventilation mode”)
3 - SETUP AND USE
Ensure the sealing and tightness of the entire circuit.
D.W.H.P functions with the heat pump as long as the temperature of the air taken in remains with the range
of -7°C to +35°C. Outside of this range, the electrical backup ensures the heating of domestic hot water.
The temperature of domestic hot water supplied by the heat pump is adjustable to 60°C. In function of the
volume of consumed water and to ensure savings, it is recommended to limit the temperature of domestic
hot water to a lower temperature.
In case of high domestic hot water consumption, D.W.H.P possesses a comfort function that increases the
heating capacity when there remains only 1/3 of the volume of the tank above 38°C (see section “PAR.10
– Minimum temperature”°.
In instances where there is a need for high amounts of domestic hot water, D.W.H.P possesses a “boost”
function (activated by the user) which ensures the quick heating of water to the desired temperature (50°C
for example) with the help of the heat pump and the electrical backup. This function is deactivated as
soon as the desired temperature is achieved (e.g. 50°C).
Periodically verify for alarms (in case of alarm, see section “Error message”).
