1. To connect the indoor unit with the outdoor unit
use the following electrical cables, protected for
outdoor use:
Cooling and heating model:
Multiple wire cable (220 - 240V, 50Hz)
2
5 wires x 1.5 mm
2
2 wires x 0.5 mm - for low voltage
(supplied with the unit).
Cooling only models:
Multiple wire cable (220 - 240V, 50Hz)
2
4 wires x 1.5 mm
2. Prepare the multiple wire (7) cable ends for
connection as shown in Fig 18.
3. Connect the cable ends to the terminals of
the indoor and outdoor units, as shown in
Fig 20.
4. Shape a loop and connect the yellow/green
ground wire (2) to ground terminal screw of
the indoor unit, as shown in Fig 20.
NOTE: For multi split and cooling only
units skip steps 5, 6, 7 and 9.
5. Prepare the twin wore cable end for connection
as shown in Fig 19.
6. Disconnect the resistor (5) from the indoor unit
twin wire cable (3) and connect the twin wire
cable (6) connector instead.
7. Connect the other end of the twin wire cable
(6) to the outdoor unit twin wire terminal (9).
8. Secure the multiple wire power cable with the
cable clamps.
9. Fasten the twin wire cable to the power cable
with cable ties.
