Keep this document close to the place where the boiler is
installed.
CAUTION
Use tools and pipe components especially designed
4
for use with R410A refrigerant.
Install the appliance on a solid, stable structure able
4
to bear its weight.
Use phosphorous-deoxidised copper for pipes
4
without welds and copper alloy to connect the pipes
carrying the refrigerant.
Use only R410A gas to fill the pipes with refrigerant.
4
Do not install the appliance in a place where it may
4
be exposed to steam, sulphuric gas or combustion,
an atmosphere with a high salt content, or which may
be covered by snow.
Ensure correct earthing.

Store the refrigeration connection pipes away from
4
dust and humidity (danger of damage to the
compressor) and cover both ends until the expansion
process is complete.
Do not use a load cylinder.

CAUTION
Activate the main switch at least 12 hours before the
4
appliance starts to function. Using the appliance just
after it is switched on may seriously damage the
internal parts.
When switching off the appliance, wait for at least 5
4
minutes of post-operation before deactivating the
main switch. Danger of breakdown or water leak.
CAUTION
In order to limit the risk of being scalded, the installation of
a thermostatic mixing valve on the domestic hot water flow
piping is compulsory.
Before carrying out any maintenance work requiring the
shutdown of the inside module, also cut the power supply
to the outside module to prevent any errors in
communication.
