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.

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.
4Install the appliance according to national regulations
on electrical installation.
4Wiring diagram: ¼See chapter Electrical principle
diagram (Installation and Service Manual).
4Connecting the appliance to the mains electricity:
¼See chapter Electrical connections (Installation
and Service Manual).
4Fuse type and calibre: ¼See chapter Electrical
connections (Installation and Service Manual).

3. Switch the appliance off.
4. Avoid contact with the refrigerant. Danger of
frost injuries.
5. Trace possible leaks and seal them
immediately.
WARNING
Depending on the settings of the appliance:
4Do not touch the refrigeration connection
pipes with your bare hands while the
appliance is running. Risk of being burnt.
CAUTION
4Do not neglect to service the appliance.
4In order to limit the risk of being scalded, the
installation of a thermostatic mixing valve on
the domestic hot water flow piping is
compulsory.
