Installation
Electrical
Cable type and sizing must be selected for the particular application and the electrical installation should conform
to the current local standards. All indoor and outdoor units are Single Phase.

Cables to the indoor unit should be routed through the ‘U’ shaped cut-out in the bottom of the removable air grille at the side of
the unit and into the rear of the electric box.

Cables to the outdoor unit should be routed under the plastic pipe / electrical connection cover on the end of the unit.

The interconnecting cable between the indoor and outdoor unit should be 3 core (2 core + E).

Connect the mains supply and interconnecting cables as per the wiring diagrams on page 20.
Access to the electrical terminals and components on the indoor unit is via the removable cover plate on the front of the unit. Removal of
the cover plate gives access to the outdoor unit contactor, the terminal block as well as the electronic controller and rocker switch
connections.
Important Note:
The mains electrical supply to the indoor unit must be via a suitably rated isolator and motor rated
circuit breaker or fuse. There is no isolator fitted to either the indoor or the outdoor unit. The rocker
switch on the front of the indoor unit is for isolating the indoor fan and electronic controller only.

the above values) and are not suitable for 60 Hz supplies.
