Since R407C is a ternary mixture, charging must take place exclusively with liquid refrigerant to ensure
the correct percentages of the three constituents.
Introduce refrigerant through the inlet in the liquid line.
A unit that was originally charged with R407C in the factory must not be charged with R22 or other
refrigerants without the written authorisation of factory
9.9 Environmental protection
The law implementing the regulations (reg. EEC 2037/00) which govern the use of ozone-depleting substances and
greenhouse gases bans the dispersal of refrigerant gases in the environment and requires whoever is in their
possession to recover them and, at the end of their useful life, either to return them to the dealer or take them to a
suitable waste disposal facility.
The refrigerant HFC R407C is not harmful to the ozone layer but is included among the substances responsible for the
greenhouse effect and thus falls within the scope of the aforesaid regulations.
Therefore, special care should be taken when carrying out maintenance work to minimise refrigerant
leaks.
10 Starting-Up Instructions for INNOV@DM-R Air-Conditioning Units
10.1 Starting operation
Before starting the unit, turn the main switch on, select the operating mode desired from the control panel and press the
”On” button on the control panel.
If the unit fails to start up, check if the service thermostat has been set according to the nominal values
provided.
You should not disconnect the unit from the power supply during periods when it is inoperative but
only when it is to be taken out of service for a prolonged period (e.g. at the end of the season).
10.2 Checks during operation
D
Check the phase sequence relay on the control board to verify whether the phases occur in the correct sequence: if
they do not, disconnect the unit from power supply and invert two phases of the incoming three-pole cable.
Never
attempt to modify internal electrical connections: any undue modifications will immediately invalidate the
warranty.
