1. IMPORTANT NOTES
a. Refer to Service Manual, File No. A90-9504 for details of indoor units and control circuits.
b. Reverse Phase Protector
The Scroll Compressor used in this unit can only rotate in one direction. For this reason a protective
device ( Reverse Phase Protector ) is fitted to prevent incorrect wiring of electrical phases. If the red LED
on the remote controller does not flash when the system is switch on, then the wiring to the outdoor unit
should be checked to ensure that the three phases are wired in the correct sequence.
c. Inner Overload Relay
If the Inner Overload Relay operates, the Magnetic contactor will remain energised, but the compressor
will stop. In this event fault Code '09' will appear on the Remote Controller.
d. Delivery Temperature Thermostat.
In the unlikely event of a gas leak a bi-metal thermostat is fitted to this unit to prevent the compressor from
overheating. During such abnormal conditions, the thermostat operates and power to the indoor unit and
remote controller is disconnected.
e. Special Refrigerant Reclaim Procedure for Scroll Compressors
When the refrigerant charge is reclaimed only from the discharge side of the Scroll Compressor, it is
possible that the suction side of the compressor remains pressurised. If a brazing torch is applied to the
suction side the pressurised refrigerant and oil mixture could ignite.
THIS COULD RESULT IN A FIRE AND / OR SEVERE PERSONAL INJURY.
The refrigerant gas MUST be reclaimed simultaneously from the discharge and the suction sides of the
outdoor unit to avoid this potential problem.
