Important Notes - Toshiba RAV-362BH-PE Service Manual

a. Refer to Service Manual, File No. A90-9503 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 the electrical phases. If the red LED on
the remote controller does not flash when the system is switched 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 Sensor (T.D. Sensor)
An additional sensor is fitted to this unit to prevent the compressor from overheating. During abnormal
conditions the following fault codes may appear:
Fault Code "1E" – Indicates a Refrigerant Gas Leak.
Fault Code "19" – Indicates T.D. sensor open circuit or short circuit.
e. Special Refrigerant Reclaim Procedure for Scroll Compressors
When the refrigerant charge is reclaimed only from the discharge side of Scroll Compressor, it is possible
that the suction side of 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 suction sides of the outdoor
unit to avoid this possible problem.
