Safety Summary
Read this section before using the air conditioners and operate it correctly. Pay special attention to signs of “Warning” and “Danger” as incorrect installation may cause injuries and
hazards, precautions during installation are listed below. Items that may cause hazards and danger are listed based on their situations. Regardless of their severity, please pay attention to items listed in either column and follow relevant instructions. Be sure to keep this manual and placed in a clearly visible place.

About Installation and Electrical Works
Installation work must be done by the dealer or qualified person. Water leakage, electric shock, fire, or unit fall may occur if you install the unit by yourself.
Danger Electrical works must be done by qualified person. Please note that self-setup could easily cause electric shock if the construction is not completely.

Precaution Before Using

Operating
Do not operate switches with wet hands, it may cause electric shock.

Do not use flammable materials in the room when air conditioner is operating. Spray paint and other flammable and volatile oil (including oil) may cause fires.

Do not set burner at the place where the air conditioner wind can directly reach, it may cause incomplete combustion.

Do not let cold air blow on the body directly for a long time, it is bad for the health.

If the unit and burner operate simultaneously, ventilation is needed, otherwise it will cause oxygen shortage.
If earth leakage breaker (ELB) or fuse is often activated, please stop the system, and Danger contact your service contractor.

always ventilation

When abnormal conditions occur (for example: burning smell), cut off the power to stop the unit immediately. To avoid electric shock and fire hazard, please contact the dealer.
Refrigerant (Fluorocarbon) for this unit is incombustible, non-toxic, and odorless. However, if the refrigerant is leaked and is contacted with fire, toxic gas will generate. Also, because the fluorocarbon is heavier than air, the floor surface will be filled with it, which could cause suffocation.
If refrigerant leakage occurs, please turn OFF the appliance and open the windows, extinguish the fire immediately and contact the dealer.
Do not insert fingers or sticks into air inlet or outlet grille into the unit while the air outlet grille is removed. The high-speed fan can cause injury.

Troubleshooting

This is Not Abnormal Situation

Cause

The LCD goes off.

Stop running

Reset the unit.

Micro-computer is active to protect the air conditioner from electromagnetic wave.
Power failure.
If power failed for only about 2 seconds, air conditioner will restart automatically.

White mist

At restaurants or kitchen. Dry operation

The performance of heat exchanger might degrade and cause the white mist because of the oil on heat exchangerfins.
Install the filter in the air panel.
Due to the blowing out temperature is too low. Please change operation status.
