Interconnection cable
In addition to the power supply cable, a cable must be provided for
the interconnection between the condensing unit and the switch box
of the air conditioning unit.
The cable must be of the type H05VV-U5X1.5 and must be
connected to terminals 1, 3, 4, 5 and 6 of the condensing unit as

Refer to the manual supplied with the air conditioning unit for the
connections at the switch box side.
HOW TO CONTINUE
After installation and connection of both the condensing unit and the
air conditioner, the complete system should be checked and tested
as described in “Checks before initial start-up” in the operation
manual supplied with the condensing unit.
Fill out the brief operation instructions form and fix it visibly near the
operating site of the refrigeration system.
