Operation
- About the operation method, refer to the operation manual that comes with each remote controller.
Operation mode select
Cool/DRY/Fan/Heat/Automatic (cool/heat)/Ventilation modes are available.
NOTE
- Heat and Automatic modes can not be available for cooling only units.
- Ventilation mode: only indicated on the following condition. Wired remote controller is used and LOSSNAY is connected.
- Automatic mode
- According to a set temperature, cooling operation starts if the room temperature is too hot and heating operation starts if the room temperature is too cold.
- During automatic operation, if the room temperature changes and remains 4° F [2 °C] or more above the set temperature for 15 minutes, the air conditioner switches to cooling mode. If the room temperature remains 4° F [2 °C] or more below the set temperature for 15 minutes, the air conditioner switches to heating mode.
Fan speed setting
NOTE
In the following cases, the actual fan speed generated by the unit will differ from the speed shown the remote controller display.
- When the unit is in STAND BY or DEFROST states.
- When the temperature of the heat exchanger is low in the heating mode. (e.g. immediately after heating operation starts)
- In HEAT mode, when room temperature is higher than the temperature setting.
- When the heater control mode is the factory setting and the heater is on, the fan will operate at high speed.
- When the unit is in DRY mode.
Ventilation
For LOSSNAY combination
The following 2 patterns of operation are available
- Run the ventilator together with the indoor unit.
- Run the ventilator independently.
NOTE
With some model configurations, the fan on the indoor unit may come on even when you set the ventilator to run independently.
NOTE
(for wireless RF thermostat):
- Running the ventilator independently is not available.
- No indication on the remote controller.
Timer
- Timer functions are different by each remote controller.
- For details on how to operate the remote controller, refer to the appropriate operation manual included with each remote controller.
Care and Cleaning
Cleaning the filters
- Clean the filters using a vacuum cleaner. If you do not have a vacuum cleaner, tap the filters against a solid object to knock off dirt and dust.
- If the filters are especially dirty, wash them in lukewarm water. Take care to rinse off any detergent thoroughly and allow the filters to dry completely before putting them back into the unit.
CAUTION
- Do not dry the filters in direct sunlight or by using a heat source, such as an electric heater: this may warp them.
- Do not wash the filters in hot water (above 122 °F [50 °C]), as this may warp them.
- Make sure that the air filters are always installed. Operating the unit without air filters can cause malfunction.
CAUTION
- Before you start cleaning, stop operation and turn OFF the power supply.
- Indoor units are equipped with filters to remove the dust of sucked-in air. Clean the filters using the methods shown in the following sketches.
Filter Removal
CAUTION
In removing the filter, precautions must be taken to protect your eyes from dust. Also, if you have to climb up on a stool to do the job, be careful not to fall. When the filter is removed, do not touch the metallic parts inside the indoor unit, otherwise injury may result.
Removal and replacement of filter
Unscrew the two thumb knobs on the panel stamped “filter” tilt forward and
pull the panel out. Grasp the edge of the filter and slide out. Re-install in
reverse. (see Fig A)
Troubleshooting
Having trouble?| Here is the solution. (Unit is operating
normally.)
---|---
Air conditioner does not heat or cool well.|
- Clean the filter. (Airflow is reduced when the filter is dirty or clogged.)
- Check the temperature adjustment and adjust the set temperature.
- Make sure that there is plenty of space around the outdoor unit. Is the indoor unit air intake or outlet blocked?
- Has a door or window been left open?
When heating operation starts, warm air does not blow from the indoor unit soon.|
- Warm air does not blow until the indoor unit has sufficiently warmed up.
During Heat mode, the air conditioner stops before the set room temperature is reached.|
- When the outdoor temperature is low and the humidity is high, frost may form on the outdoor unit. If this occurs, the outdoor unit performs a defrosting operation. Normal operation should begin after approximately 10 minutes.
Airflow direction changes during operation or airflow direction cannot be set.|
- During Heat mode, the vanes automatically move to the horizontal airflow direction when the airflow temperature is low or during defrosting mode.
When the airflow direction is changed, the vanes always move up and down past the set position before finally stopping at the position.|
- When the airflow direction is changed, the vanes move to the set position after detecting the base position.
A flowing water sound or occasional hissing sound is heard.|
- These sounds can be heard when refrigerant is flowing in the air conditioner or when the refrigerant flow is changing.
A cracking or creaking sound is heard.|
- These sounds can be heard when parts rub against each due to expansion and contraction from temperature changes.
The room has an unpleasant odor.|
- The indoor unit draws in air that contains gases produced from the walls, carpeting, and furniture as well as odors trapped in clothing, and then blows this air back into the room.
A white mist or vapor is emitted from the indoor unit.|
- If the indoor temperature and the humidity are high, this condition may occur when operation starts.
- During defrosting mode, cool airflow may blow down and appear like a mist.
Water or vapor is emitted from the outdoor unit.|
- During Cool mode, water may form and drip from the cool pipes and joints.
- During Heat mode, water may form and drip from the heat exchanger.
- During defrosting mode, water on the heat exchanger evaporates and water vapor may be emitted.
“ ” appears in the remote controller display.|
- During central control, “ ” appears in the remote controller display. and air conditioner operation cannot be started or stopped using the remote controller.

- When cooling operation stops, the drain pump operates and then stops. Wait approximately 5 minutes.
Noise is louder than specifications.|
- The indoor operation sound level is affected by the acoustics of the particular room as shown in the following table and will be higher than the noise specification, which was measured in anechoic room.
Nothing appears in the wireless remote controller display, the display is faint, or signals are not received by the indoor unit unless the remote controller is close.|
