SUMMARY
•The units referred to within this manual conform with the protection requirements of Directives 89/336/EEC Electromagnetic Compatibility and 73/23/EEC Low Voltage.
•Operating conditions of units are as follows:
TEMPERATURE
OUTDOOR TEMPERATURE |
-2 TO 43°C (COOL) |
|
-10 TO 21°C (HEAT) |
|
|
ROOM TEMPERATURE |
18 TO 32°C (COOL) |
|
15 TO 29°C (HEAT) |
|
|
ROOM HUMIDITY |
LESS THAN 80% (COOL) |
|
|
Note 1: Cooling Capacity is based on the following temperature conditions:
Indoor air inlet temperature 27°C DB, 19°C WB.
Outdoor air inlet temperature 35°C DB.
Note 2: Heating Capacity is based on the following temperature conditions:
Indoor air inlet temperature 20°C DB.
Outdoor air inlet temperature 7°C DB, 6°C WB.

1.IMPORTANT NOTES
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.DeliveryTemperature 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.
