reduced physical, sensory or mental capacity, or those inexperienced or not
understanding this manual unless they have received prior instruction or
supervision from someone responsible for their safety, about the use of the
appliance.
Children must be supervised to ensure they do not play with the appliance.
This appliance may be used by children of 8 years or over, and by people of
reduced physical, sensory or mental capacity, or those inexperienced or
ignorant if they are properly supervised or if they have been given
instructions about the safe use of the appliance, and made aware of the
associated risks. Children must not play with the appliance. Children must
not clean or maintain the appliance without supervision.
INSTALLATION
WARNING: Product heavy, handle with care:
1/Install the appliance in a frost-free room. The warranty does not cover
destruction of the appliance through excess pressure caused by a blockage in
the safety valve.
2/Ensure that the wall on which it is mounted can support the weight of the
appliance filled with water.
3/If the appliance has to be installed in a room or location with an ambient
temperature always above 35°C, this room must be ventilated.
4/Place the appliance in an accessible place.
5/Refer to the installation diagrams.
The size of space needed for the
appliance to be correctly installed
is specified in the chapter installation.
It is mandatory for the water heater
to be fixed to the floor using the
fixing attachment provided.
The user keep this manual

WARNINGS
WATER CONNECTION
A new safety unit must be installed at the intake to the water heater, in a
frost-free environment, with dimensions of 3/4" and with pressure of 7 bar -
0.7 MPa, compliant with local regulations in force.
A pressure reducer (not supplied) is needed when pressure is more than 5
bar (0.5 MPa) and it will be placed on the main supply.
Connect the safety unit to a drain pipe kept in the open air, in a frost-free
environment, with a permanent downward gradient, to remove any
expansion water from the heating process, or drainage water from the waterheater.
The operating pressure of the heat exchanger circuit must not exceed 3 bar -
0.3 Mpa, and its temperature must not be higher than 85°C.
ELECTRIC CABLING
Before removing the cover, always make sure that the power is turned off, to
prevent any risk of injury or electric shock.
There must be an omni-polar power cut-off (circuit-breaker or fuse) fitted
upstream of the electrical installation, compliant with local rules in force
(30mA differential circuit-breaker). The system must be earthed. A special
terminal, marked , is provided for the purpose.
French law strictly forbids connection of a product fitted with a cable and
plug.
MAINTENANCE - REPAIR
Drainage: Cut the power and cold water supplies, open the hot water valves
then operate the safety unit's drain valve.
The drainage device has a pressure limiting device that must be operated
regularly to remove any scale deposits and check it is not blocked.
If the power cable is damaged, the manufacturer, the after-sales service or
similarly qualified people must replace it, for safety's sake.
This manual is also available from the customer service department (contact
details shown on appliance).

Overview Installation Operation Maintenance Warranty
Description
1. Important recommendations
1.1. Safety directives
Installation and commissioning work on thermodynamic water-heaters may pose hazards because of highpressure and live electrical parts.
Thermodynamic water heaters must be installed, brought into service and maintained by trained and
qualified personnel only.
1.2. Transport and storage
The product may be turned through 90° on one side. The side permitted is
shown clearly on an information label placed on the product packaging. The
product must not be turned on the other sides. An inclination indicator is used
to check that the product has been transported and handled in accordance
with our recommendations. We recommend you should be careful to respect
these instructions. Our commercial warranty will not apply if the inclination
indicator is red. We will not be responsible for any fault in the product
resulting from transport or handling of the product in a way that does not
comply with our recommendations.
2. Content of package

3. Transport
The product integrates several handles to
facilitate handling to the installation site.
To transport the boiler to the installation
site, always use the lower grips and top
handles as shown.
4. Working principles
The heat pump water heater uses unheated air to heat
domestic hot water.
The coolant in the heat pump sets up a thermodynamic
cycle which allows the energy from the unheated ambient
air or the outside air to be transferred to the water in the
cylinder.
The air is passed through the device by a fan, ventilating the
various components including the evaporator.
As it passes through the evaporator, the coolant evaporates
and conveys calories to the intake air.
The compressor compresses the coolant causing its
temperature to rise.
This heat is transmitted by the condenser to the domestic
water stored in the cylinder.
The coolant expands in the thermostatic expansion valve
and cools down. It is then once again ready to receive heat
in the evaporator.
The colder the air, the harder it is to withdraw calories from
it. Similarly, the higher the hot water setting, the harder it is
for the heat pump to return the calories withdrawn
Observe the recommendations and handling on the packaging of the water heater.
