PHSAE SEQUENCER The unit with Scroll Compressor can only rotate in one direction. For this reason, a protective device (phase sequencer) is fitted to prevent incorrect wiring of the electrical phases. When the three phases are not connected correctly, the phase sequencer operates, and the unit will not start. This devise is located in the control box of the outdoor unit.

SPECIAL PRECAUTIONS WHEN DEALING WITH REFRIGERANT R410A UNIT 1) WHAT IS NEW REFRIGERANT R410A? R410A is a new HFC refrigerant which does not damage the ozone layer. The working pressure of this new refrigerant is 1.6 times higher than conventional refrigerant (R22), thus proper installation / servicing is essential.
Page 29
d) When charging R410A, ensure that only liquid is being withdrawn from the cylinder or can. This is to ensure that only the original composition of R410A is being delivered into the system. The liquid composition can be different from the vapor composition. Dip-pipe Invert cylinder without dip-pipe...

10. SERVICING AND MAINTENANCE Warning: Disconnect from main supply before servicing the air conditioner. The unit is designed to give long life operation with minimum maintenance required. However, it should be regularly checked and the following items should be given due attention. Components Maintenance Procedure Recommended Schedule...
FOR ALC OUTDOOR MODELS The design of the ALC outdoor series allows servicing to be carried out readily and easily. The removal of the top side, front and back panel make almost every part accessible. Under normal circumstances, these outdoor units only require a check and cleaning of air intake coil surface once quarterly.
11. TROUBLESHOOTING When a malfunction of the air conditioner unit is detected, immediately switch off the main power supply before proceeding with the following troubleshooting procedures. The following are common fault conditions and simple troubleshooting tips. If any other fault conditions which are not listed occur, contact your nearest local dealer.

DIAGNOSTIC GUIDELINES By means of pressure readings: Data Pressure Probable cause Circuit High side • 1. Overcharged with refrigerant. Low side 2. Non-condensable gases in refrigerant circuit (e.g. air) • 3. Obstructed air-intake / discharge. 4. Hot air short circuiting in outdoor unit. High side •...
Page 111
BY MEANS OF DIAGNOSTIC FLOW CHART : Generally, there are two kinds of problems, i.e. starting failure and insufficient cooling/heating. “Starting failure” is caused by electrical defect while improper application or defects in refrigerant circuit causes “Insufficient cooling / heating”. i) Diagnosis of Electric Circuit The most common causes of air conditioner failure to “start”...
Page 112
ii ) Diagnosis of Refrigerant Circuit / Application There might be some causes where the unit starts running but does not perform satisfactorily, i.e. insufficient cooling. Judgement could be made by measuring temperature difference of indoor unit’s intake and discharge air as well as running current.
