IMPORTANT : * The fi gures shown in the table are for information purpose only. They should be checked
and selected to comply with the local/national codes of regulations. This is also subject to the type of installation and conductors used.
** The appropriate voltage range should be checked with label data on the unit.

switch with a minimum 3mm contact gap and fuse/circuit breaker as recommended in the fixed installation circuit.
• All wires must be fi rmly connected.
• All wires must not touch the refrigerant piping, compressor or any moving parts of the fan motor.
• The connecting wires between the indoor unit and the outdoor unit must be clamped on the wire clamps.
• The power supply cord must be equivalent to H07RN-F (245IEC57) which is the minimum requirement.

A5LCY_(i) Application Information
Refrigerant Piping
Piping Length and Elevation
If the pipe is too long, both the capacity and reliability of the unit will drop. As the number of bends increases, resistance to the fl ow of refrigerant system increases, thus lowering cooling capacity. As a result, the compressor may become defective. Always choose the shortest path and follow the recommendations as tabulated below:

(After Extended Shutdown)
• Inspect thoroughly and clean indoor and outdoor units.
• Clean or replace air fi lters.
• Clean condensates drain line.
• Clean clogged indoor and outdoor coils.
• Check fan imbalance before operation.
• Tighten all wiring connections and panels.
• Check for refrigerant leakage.
Outdoor Models
The design of the A5LCY outdoor series allows servicing to be carried out easily. The removal of the top, front and side panels makes almost every part accessible. Under normal circumstances, these outdoor units only require a check and cleaning of air intake coil surface once every 3 months. However, if a unit is installed in areas subjected to much oil mist and dust, the coils must be regularly cleaned by qualifi ed Air Conditioner Service Technicians to ensure suffi cient heat exchange and proper operation. Otherwise, the systems life span may be shortened.
Caution
• Do not charge OXYGEN, ACETYLENE OR OTHER FLAMMABLE and poisonous gases into the unit when performing a leakage test or an airtight test. These gases could cause severe explosion and damage if exposed to high temperature and pressure.
• It is recommended that only nitrogen or refrigerant be charged when performing the leakage or airtight test.

Troubleshooting
Fault Condition
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. DO NOT attempt to troubleshoot the unit by yourself.
No Fault conditions Possible causes / corrective actions
1 The air conditioner unit will not resume after
power failure.
2 The airfl ow is too slow or room cannot be
cooled suffi ciently.
3 Discharge airfl ow has bad odor. • Cigarettes, smoke particles, perfume and
4 Condensation on the front air grille of the indoor
unit.
5 Water fl owing out from the air conditioner. • Switch off the unit and contact your nearest
6 Hissing airfl ow sound from the air conditioner
unit during operation.
7 The wireless controller display is dim. • The batteries are discharged.
8 Compressor operates continuously. • Dirty air fi lter. Clean the air fi lter.
9 No cool air comes out during cooling cycle, or
no hot air comes out during heating cycle.
10 On heating cycle, warm air does not come out. • Unit is in defrost mode. Heating operation will
• The auto restart function is not functioning. Please turn on the unit with the wireless / wired controller.
• The air fi lter is dirty.
• The doors and windows are opened.
• The air suction and discharge of both indoor and outdoor units are clogged or blocked.
• The regulated temperature or temperature setting is not low enough.
others, which might have adhered onto the coil, may cause odor.
• Contact your nearest dealer.
• This is caused by air humidity after an extended period of operation.
• The set temperature is too low. Increase the temperature setting and operate the unit at high fan speed.

• Liquid refrigerant fl owing into the evaporator coil.
• The batteries are not correctly inserted.
• The assembly is not good.

Heat Pump Unit
The table shows the LED indicator lights for the air conditioner unit under normal operation and fault conditions. The LED indicator lights are located at the side of the air conditioner unit.The heat pump units are equipped with an “auto” mode sensor whereby it will provide reasonable room temperature by switching automatically to either “cool” or “heat” mode according to the temperature set by the user.

Diagnosis Step
1. Hold down ON TIMER CANCEL button or OFF TIMER CANCEL button for 5 seconds, a “ ” indication
fl ashes on the temperature display section.
2. Press ON TIMER CANCEL or OFF TIMER CANCEL repeatedly until indoor buzzer produces a long beep. This indicates the error code, refers to Error Codes table and is displayed on the temperature display section.
3. A short beep or two consecutive beeps indicate non-corresponding error codes.
4. To cancel the error code display, hold down ON TIMER CANCEL or OFF TIMER CANCEL button for 5 seconds. Alternatively, the code display will cancel itself if the button is not pressed for 1 minute.
Error Code Diagnosis by Unit Last State Memory Using Wireless Handset
1. Remove battery from wireless handset.
2. Wait for the display to fi nally go off (as this handset uses very small amount of power, hence it takes
longer for the memory to reset).
3. Replace battery again and immediately (before display comes back on the LCD screen), press on Mode
and ON/OFF buttons together until you see “00” is being displayed.
4. Press Mode button to 5:00.
5. Press ON/OFF button once.
6. After that, remove battery from wireless handset and wait until the display has gone off. Then, replace
battery again into the handset.
7. Finally, repeat the fault diagnosis steps by wireless handset GS02 above.
