7.1 Preparing the installation site
Do NOT install the unit in places often used as work place. In case of construction
works (e.g. grinding works) where a lot of dust is created, the unit MUST be
covered.
Choose an installation location with sufficient space for carrying the unit in and out
of the site.
NOTICE
This unit is designed for operation on 2 temperature zones:
▪ underfloor heating in the main zone, this is the zone with the lowest water
temperature,
▪ radiators in the additional zone, this is the zone with the highest water
temperature.
WARNING
The appliance shall be stored in a room without continuously operating ignition
sources (example: open flames, an operating gas appliance or an operating electric
heater).
WARNING
DO NOT reuse refrigerant piping that has been used with any other refrigerant.
Replace the refrigerant pipes or clean thoroughly.
