OPERATING INSTRUCTIONS
Airflow direction control
Range
Vertical louver (three places)
Adjust the air flow direction properly otherwise, it might cause discomfort or uneven room temperatures. Adjust the horizontal louver using the remote controller. Adjust the vertical louver manually.
To set the vertical air flow(Up--Down) direction Perform this function while the unit is in operation. Use the remote controller to adjust the air flow direction. The horizontal louver can be moved at a range of 6 for each press, or swing up and down automatically depending on model. Please refer to the REMOTE CONTROLLER OPERATION MANUAL that come with your unit for details.
To set the horizontal air flow direction (left - right)
Move the vertical louver manually to adjust the air flow in the direction you prefer. IMPORTANT: Before adjusting the vertical louvers, the supply power must be disconnected to prevent electrical shock or injury. For some models, the vertical louver can be adjusted by using the remote controller. Please refer to the REMOTE CONTROLLER OPERATION MANUAL that comes with your unit for details.
O
Range
CAUTION
Do not operate the air conditioner for long periods with the air flow direction set downward in cooling or dehumidifying mode. Otherwise, condensation may occur on the surface of the horizontal louver causing moisture to drop on to the floor or on furnishings. Do not move the horizontal louver manually unless it is necessary. Always use the remote controller, where applicable. When the air conditioner is started immediately after it was stopped, the horizontal louver might not move for approximately 10 seconds. Open angle of the horizontal louver should not be set too small, as COOLING or HEATING performance may be impaired due to too restricted air flow area. Do not operate unit with horizontal louver in closed position. When the air conditioner is connected to power (initial power), the horizontal louver motor may generate a sound for 10 seconds, this is a normal occurance.

Operational modes
AUTO operation
When you set the air conditioner to AUTO mode, it will automatically select cooling, heating or fan only operation depending on what temperature you have set and the current room temperature. The air conditioner will control room temperature automatically around the temperature set point you selected. If the AUTO mode is uncomfortable, you can select desired conditions manually by changing the mode to cooling, heating, or fan only directly.

To achieve optimal performance, please note the following: Adjust the air flow direction correctly so that it is not directed on people, but rather in the room Adjust the temperature to achieve the highest comfort level. Do not adjust the unit to excessive temperature levels. Close doors and windows on COOL or HEAT modes, or performance may be reduced. Use TIMER ON button on the remote controller to select a time you want to start your air conditioner. Do not put any objects near air inlet or air outlet, as the efficiency of the air conditioner may be reduced and the air conditioner may stop running. Clean the air filter periodically, otherwise cooling or heating performance may be reduced. Do not operate unit with horizontal louver in the closed position.

CARE AND MAINTENANCE
Cleaning the Grille, Case and Remote Controller
NOTE: Supply power must be disconnectd before cleaning the indoor unit.
Turn the system off before cleaning. To clean, wipe with a soft, dry cloth. Do not use bleach or abrasives.
CAUTIONS
A cloth dampened with cold water may be used on the indoor unit if it is very dirty. Then dry it with a dry cloth after cleaning. Do not use a chemically treated cloth or duster to clean the unit. Do not use benzine, thinner, polishing powder, or similar solvents for cleaning. These may cause the plastic surface to crack or deform. Never use water hotter than 40 C to clean the front panel, it could cause deformation of discoloration.

Cleaning the air filter
Caution
Do not touch the metal parts of the unit when removing the filter. Injuries can occur when handling sharp metal edges. Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation, leading to possible electric shock. When cleaning the unit, first make sure that the power and circuit breaker are turned off.
A clogged air filter reduces the cooling efficiency of this unit. Please clean the filter once every 2 weeks.
1. Lift the indoor unit panel up to an angle until it stops with a clicking sound.
2. Hold the handle of the air filter and lift it up slightly to remove it from the filter holder, then pull it downwards.
3. Remove the AIR FILTER from the indoor unit. Once every two weeks,
clean the AIR FILTER with a vacuum cleaner or water, then dry it in cool place.

Frost may be generated on the outdoor unit during heat cycle when outdoor temperature is low and humidity is high, resulting in lower heating efficiency of the air conditioner. During this condition the air conditioner will stop heating operation and start defrosting automatically. Defrost time may vary from 4 to 10 minutes according to the outdoor temperature and the amount of frost build up on the outdoor unit.
2. A white mist coming out of the indoor unit A white mist may generate due to a large temperature difference between air inlet and air outlet on COO A white mist may generate due to moisture generated from defrosting process when the air conditioner restarts in HEAT mode operation after defrosting.
3. Typical sounds You may hear a low hissing sound when the compressor is running or has just stopped running. This sound is the sound of the refrigerant flowing or coming to a stop. You can also hear a low "squeak" sound when the compressor is running or has just stopped running. This is caused by heat expansion and cold contraction of the plastic parts in the unit

4. Dust is blown out from the indoor unit. This is a normal condition when the air conditioner has not been used for a long time or during first use of the unit, and an accumulation of dust has formed on the unit’s outlet. Cleaning dust off of the unit before operation may prevent this.
5. A peculiar smell comes out of the indoor unit. This is caused by the indoor unit giving off smells permeated from building material, from furniture, or smoke. However, a burning sme and call an authorized servicer if such smell exists.
6. Operating mode changes to fan only mode. When indoor temperature reaches the temperature set point on air conditioner, the compressor will stop automatically, and the air conditioner changes to FAN only mode. The compressor will start again when the indoor temperature rises in above the set point in COOL mode or falls in below the set point in HEAT mode.
The indoor or outdoor fan will stop running when defrosting.

Maintenance
If you plan to store the unit for a long time, perform the following: (1) Operate the fan for about half a day to dry the inside of the unit. (2) Stop the air conditioner and disconnect power. Remove the batteries from the remote controller. (3) The outdoor unit requires periodic maintenance and cleaning. Do not attempt to do this yourself. Contact an authorized servicer.
Checks before placing back into operation
Check that the wiring is not broken off or disconnected. Check that the air filter is installed. Check if the air outlet or inlet is blocked after the air conditioner has not been used for a long time.
