2.7.4 - Electric connection
Before connecting the air conditioner, make sure that:
a. The power supply voltage and frequency values respect that specified on the appliance data
plate.
b. The power supply line has an effective earth connection and it is correctly dimensioned for
maximum absorption of the climate control unit.
c. to select the minimum section of the power supply cable, refer to the table below.
advised cables:
- Indoor unit power cable:
H05VV-F or H05V2V2-F
- Outdoor unit power cable:
H07RN-F or H05RN-F
- Cable for the signal: H07RN-F
The dimension of the power cable,
signal cable, of the fuse and of the
switches must be determined by the
maximum current absorbed by the unit. The maximum current is indicated on the
technical data label located on the side of the unit.
A suitable omnipolar disconnection device must be envisioned on the appliance
mains electric power supply, in compliance with the national installation rules.
It must be checked that the electric power supply has an effective earth and suitable
protections against overloads and/or short circuits.
The use of a ceramic fuse of the characteristics shown in the table is advised (or
other devices with the same functions).
The connection to the mains power supply must be made by the installation
technician (excluding mobile appliances, for which fixed installation by qualified
personnel is not required) in compliance with the regulations in force.
BEFORE MAKING THE ELECTRIC CONNECTION, MAKE SURE THAT THE UP-
STREAM ISOLATING SWITCH IS AT "0" (OFF) AND THE PROTECTIONS OF THE
INDOOR AND OUTDOOR UNITS ARE POSITIONED CORRECTLY.
d. Connect the power supply cable terminals (32) (not supplied) to the terminal board (28) positioned in
the outdoor unit electric connections compartment.
e. Before re-installing the protection of the electric connections, fix the power supply cable via the relevant
cable tie (31), positioned in proximity of the outdoor unit terminal board (28).
2.7.5 - Delivery of the system
When all checks and controls regarding the correct operation of the plant have been completed, the installation
technician must illustrate the following to the purchaser:
- the basic operational features,
- the plant switch-on and switch-off instructions,
- the normal use of the remote control,
- the first practical advice for routine maintenance and cleaning.
