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 shall not be made by children
without supervision.
1.1.1. Installation
4Allow the space necessary for the correct installation of
the appliance:
¼See chapter Positioning of the appliance
(Installation and Service Manual).
1.1.2. Hydraulic connections
4The appliance is intended to be connected
permanently to the mains water supply.
4Maximum / minimum water pressure at the inlet:
¼See chapter Technical specifications.
4The pressure limiter device must be started up
regularly in order to remove any limescale deposits and
check that it is not blocked.
4Draining: Turn off the domestic cold water inlet. Open
a hot water tap in the system and then open the safety
unit valve. When the water stops flowing, the appliance
has been drained.

619/01/2015 - 300026515-001-05

4A pressure reducer (not provided) is necessary when
the mains pressure exceeds 80% of the calibration of
the safety valve or unit. It will be installed upstream of
the appliance.
4As water may run out of the discharge pipe on the
pressure limiter device, the discharge pipe must be
kept open to the open air.
4Connect the pressure limiter device to a drainage pipe,
kept in the open air, in a frost-free environment, on a
continuous downward slope.
1.1.3. Electrical connections
4Allowance must be made for a means of disconnection
in the fixed pipes in accordance with the regulations on
installations.
4If the mains power lead is damaged it must be replaced
by the original manufacturer, the manufacturer’s dealer
or another competent person to prevent hazardous
situations.
4This appliance must not be powered via an external
switch such as a timer or be connected to a circuit that
is regularly switched on and off by the electricity
supplier.

4.3 Operating principle
The thermodynamic DHW tank uses unheated ambient air or outside
air to prepare DHW.
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 sucked in by a compressor in vapour form, 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.
