Sharp edges and coil surfaces are potential injury hazard. Avoid from contact with them. Caution

If the condensing unit is operated in an atmosphere containing oils (including machine oils), salt (coastal area), sulphide gas (near hot spring, oil refinery plant), such as substances may lead to failure of the unit.

Recommended fuse A 15 20 Refrigerant Piping

When the piping length becomes too long, both the capacity and reliability drop. As the number of bend increases, system piping resistance to the refrigerant flow increases, thus lowering the cooling capacity, and as the result the compressor may become defective. Always choose the shortest path and follow the recommendation as tabulated below:

Additional Charge The refrigerant gas is charged in the outdoor unit and if the piping length is 7.5m, additional charge of the refrigerant after vacuuming is not necessary. When the piping length is more than 7.5m, additional charge (g) per additional 1m length as tabulated. R410A – Heatpump/Cooling

Diagnosis Step 1. Hold down ON TIMER CANCEL button or OFF TIMER CANCEL button for 5 seconds, a “ ”

indication flashes on the temperature display section. 2. Press 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 button 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 1. Remove battery from remote controller 2. Replace battery again into remote controller 3. Press Mode & ON/OFF buttons together 4. Press Mode button to 5:00 5. Press ON/OFF once 6. Repeat the fault diagnosis steps by wireless handset GS02 �
