specialized cable. 

(3) After connecting the power cord, please affix the electric box cover properly. 

(4) Never fail to comply with the nitrogen charge requirements.Charge nitrogen when welding pipes. 

(5) Never short-circuit or cancel the pressure switch to prevent unit damage.   

(6) Connect the wired controller before energization; otherwise wired controller could be damaged. 

(7) Before using the unit, please check if the piping and wiring are correct to avoid water leakage, refrigerant leakage, 
electric shock, or fire etc.. 

(8) Do not insert fingers or objects into air outlet/inlet grille. 

(9) Open the door and window and keep good ventilation in the room to avoid oxygen deficit when the gas/oil heating 
equipment is used. 

(10) Never start up or shut off the air conditioner by plugging or unplugging the power cord. 

(11) Let the unit run for at least five minutes after startup; otherwise it will affect oil return of the compressor. 

(12) Do not allow children operate this unit. 

(13) Do not operate this unit with wet hands. 

(14) Turn off the unit or cut off the power supply before cleaning, otherwise electric shock or injury may occur. 

(15) Never spray or flush water towards unit, otherwise malfunction or electric shock may occur. 

(16) Do not expose the unit to the wet or corrosive circumstances. 

(17) Under cooling mode, please don't set the room temperature too low. Keep the temperature difference between indoor 
and outdoor unit within 5°C (9°F). 

(18) User is not allowed to repair the unit. Faulty service may cause electric shock or fire. Please contact a qualified service

Faulty installation may result in water leakage, electric shock or fire etc.. 

(21) Be sure to use the appropriate accessories and parts to prevent the water leakage, electric shock and fire      accidents. 

(22) Make sure the unit can be grounded properly and securely to avoid electric shock. Please do not connect the ground 
wire to gas pipe, water pipe, lightning rod or telephone line.   

(23) Connect power to the unit 8 hours before operation. Do not cut off the power when it will not be used for a short period 
of time, i.e. overnight (to protect the compressor).   

(24) If refrigerant leakage occurs during installation, please ventilate immediately. Toxic gas will resuslt if the refrigerant gas 
meets spark or open flame. 

(25) Volatile liquid, such as paint thinner or gasoline will damage the unit appearance.Only use soft cloth with a little mild
