Safety Precautions

WARNING

※Before the cleaning of the air conditioner, it must be shut down and the electricity must be cut off for more than 5 minutes, otherwise there might be the risk of electric shocks.
※Do not use gasoline, benzene, thinner or any other chemicals, or any liquid insecticide on the air conditioner, as these substances may cause flaking off of the paint, cracking or deformation of plastic parts.
※Never attempt to clean the unit by pouring water directly over any of the surface areas, as this will cause deterioration of electrical components and wiring insulation.

Clean the unit

When the unit is contaminated, clean it gently with a wrung towel using tepid water below 40°C (104°F).

Clean the Air Filter

1. Remove the air filter

Take out the upper air filter and the lower air filter.

* When the water level of the bottom tray reaches predetermined level, the digital display area shows "P1" and the WATER FULL indicator light illuminates.

Carefully move the unit to a drain location, remove the bottom drain plug and let the water drain away. Reinstall the bottom drain plug and restart the machine until the P1 symbol disappears. If the error repeats, call for service.

NOTE: Be sure to reinstall the bottom drain plug before using the unit.

Installation

Safety Precautions

Install the exhaust duct into the wall

1. Prepare a hole in the wall. Install the wall exhaust adaptor onto the wall by using 4 expansion screw sleeve and type C screws, be sure to fix thoroughly.
2. Connect the exhaust duct to wall exhaust adaptor.(Fig.G)

Note: 1. The duct can be compressed to 270mm minimum and extended to 1500mm maximum. It is better to keep the duct length to a minimum length. 2. Stretching or bending the duct excessively will affect the cooling efficiency. (As the following fig. Shows)

Water drainage

* During dehumidifying mode, remove the upper drain plug from the back of the unit. Attach the drain hose to the hole. Place the other end of the hose in the drainage way or other drain areas.

⚠ WARNING

Failure to follow the below precaution could result in electrical shock, fire or personal injury.

2. Do not use an extension cord or plug adaptor with this unit.

∅ CAUTION

• Don't apply the cold air to the body for a long time. It will deteriorate your physical conditions and cause health problems.
• Don't block air inlet or air outlet, otherwise, the cooling capacity will be weakened, even cause system stop operating.
• Close the windows and doors, otherwise, the cooling capacity will be weakened.
• If the air filter is very dirty, the cooling capacity will be weakened. Please clean the air filter regularly.

Notices for R410A models

Refrigerant leakage contributes to climate change. Refrigerant with lower global warming potential (GWP) would contribute less to global warming than a refrigerant with higher GWP, if leaked to the atmosphere. This appliance contains a refrigerant fluid with a GWP equal to [2088]. This means that if 1 kg of this refrigerant fluid would be leaked to the atmosphere, the impact on global warming would be [2088] times higher than 1 kg of CO₂, over a period of 100 years. Never try to interfere with the refrigerant circuit yourself or disassemble the product yourself and always ask a professiona.
