Remove the front panel, the electric parts appear at the
front side.
The power supply cables can be inserted into the pipe
holes. Be sure to fix the power cable with bundling band
sold on the market so that they do not make contact with
the compressor and the hot pipes.
To ensure good tensile strength, the electric cables must be
fastened using the cable-holder on the plate.
(Only for sizes 12 and 15 use the strain relief supplied with
the unit). See fig. 16 for power supply cabling.
The unit can be controlled and set via:
• User Comfort Interface wire control 33AW-CS1B
(Optional)
• Wire remote control 33AW-RC1 (Optional)
• Switches (not supplied)
For the electrical connections refer to Figure 17, while, for
use, refer to the relative manuals.
Wired control For installation of wired remote controller please refer to the control installation manual.
Size the cable, the cables must be H07 RN-F type.
According to the installation instructions, all devices for disconnection from the power supply
Power supply mains must have a contact opening (4 mm) to allow total disconnection according to the conditions
provided for the overvoltage class III.
To prevent any risk, the power cable must only be replaced by the technicians of the after-sales service.
For the 3Ph units be sure to attach the provided clamp filter (11) to the power supply wire in order
