1 Safety
1.1 Safety
Danger
This appliance can be used by children aged from
8 years and above and persons with reduced
physical, sensory or mental capabilities or lack of
experience and knowledge if they have been
given supervision or instruction concerning use of
the appliance in a safe way and understand the
hazards involved. Children shall not play with the
appliance. Cleaning and user maintenance
should not be carried out by children without adult
supervision.
1.1.1
Installation
Ensure sufficient space is available to allow correct
installation of the appliance.
See
Position of the appliance section (Installation and
Service Manual).
1.1.2
Water connections
The appliance is intended to be permanently
connected to the water mains.
Maximum / minimum water inlet pressure:
See
Technical specifications section.
The safety valve (not supplied) must be regularly
operated in order to remove limescale deposits and
ensure that it is not blocked.
Draining: shut off the domestic cold water inlet. Open
a hot water tap in the installation and then open the
drain valve on the cold water inlet. When the water
stops flowing, the appliance has been drained.
A pressure reducer (not provided) is necessary when
the supply pressure exceeds 80% of the calibration of
the safety valve or safety unit and it must be located
upstream of the appliance.
As water may flow out of the discharge pipe on the
pressure limiter device, the discharge pipe must be
kept clear and open.
1 Safety
4 300026515 - v10 - 28082018
Connect the pressure limiter device to a drain pipe,
kept open to the air, in a frost-free environment, and
at a continuous downward gradient.
1.1.3 Electrical connections
A disconnection device must be fitted to the
permanent pipes in accordance with installation rules.
If the power cable is damaged, it must be replaced by
the manufacturer, its after sales service or persons
with similar qualifications in order to obviate any
danger.
This appliance must not be powered through an
external switch, such as a timer, or be connected to a
circuit which is regularly switched on and off by the
electricity provider.
Install the appliance in accordance with national rules
on electrical installation.
The control panel for the appliance must remain
switched on to ensure that the impressed current
anode can operate. Failure to comply with this
instruction may cause deterioration to the water
heater tank and cancel its warranty.
Wiring diagram:

Others
Danger
If flue gas is released or there is a refrigerant
leak:
Do not use a naked flame, do not smoke, do not
operate electrical contacts or switches (doorbell,
light, motor, lift, etc.).
Open the windows.

Avoid contact with the refrigerant. Danger of
frost injuries.
Locate the probable leak and seal it
immediately.
Warning
According to the appliance settings:
Do not touch the refrigerant connection pipes
with bare hands when the appliance is
operating. Risk of scalding.
Caution
Do not neglect to service the appliance.
In order to limit the risk of being scalded, a
thermostatic mixing valve must be installed on
the domestic hot water flow pipes.

4.3 Operating principle
The thermodynamic water heater uses unheated ambient air or outdoor air
to prepare domestic hot water.
The refrigerant circuit is a closed circuit in which the R-134a refrigerant
plays the role of an energy carrier.
The heat from the intake air is transferred to the refrigerant in the finned
heat exchanger at a low evaporation temperature.
The refrigerant is drawn in, in vapour form, by a compressor which raises it
to a higher pressure and temperature and sends it to the condenser. In the
condenser, the heat extracted in the evaporator and some of the energy
absorbed by the compressor are released into the water.
The refrigerant is depressurised in the thermostatic expansion valve and
then cooled. The refrigerant can again extract the heat contained in the
intake air from the evaporator.

The air taken in must in no circumstances be dusty.
Adequate thermal insulation in relation to adjacent living spaces
is recommended.
Temperature of the ambient air or of the air taken in by the heat
pump for optimum running: 10 to 35 °C.
Install the appliance in a dry, frost-free room at a minimum temperature
of 7 °C.
Install the appliance on a flat, solid surface.
Install the appliance on a base frame. The base frame must be able to
support the load sufficiently at all times.

1 Garage Unheated room.
Enables recovery of the free energy released by your vehicle's engine when switched off af
ter use or by household appliances in operation.
2 Via outside air Connection to the outside air may lead to overconsumption of electricity if the outside air
temperature falls outside the operating range.
Minimum distance to be observed for the ducts if intake and backflow are done on the same
façade: 700 mm.
Important
Risk of inconvenience in Eco operating mode: the immersion heater never
switches on. In addition, when the outdoor temperature is low, the output
of the thermodynamic water heater is reduced. The domestic hot water
set point temperature is not reached.
3 Habitable room Can obtain free heat from the garage.
4 Laundry room Unheated room.
Enables the dehumidification of the room and recovery of the energy wasted by washing
machines and tumble dryers.
5 Via crawl space
Connection to the crawl space is possible if the volume is greater than 30 m
3
.
The crawl space must be frost-free (temperature > 1 °C)
Important
If the crawl space is poorly insulated, thermal losses from the home will
be greater.
Position of the appliance in a cupboard
1 With EH434 (reduced elbow kit): 800 mm x 800 mm - ducted
installation
2 With EH77 or EH273: 1100 mm x 1100 mm - ducted installation
Be sure to make the air duct connections absolutely leak proof.
We strongly recommend installing the control system in the living room.
