Safety
Precautions
Prior to Operation
Preparing for operation
1 Contact an installation specialist for installation.
2 Plug in the power plug properly.
3 Do not use a damaged or non-standard power cord.
4 Do not share the same outlet with other appliances.
5 Do not use an extension cord.
6 Do not start/stop operation by plugging/unplugging the power cord.
Usage
1 Being exposed to direct airflow for an extended period of time could be hazardous to your health. Do not
expose occupants, pets, or plants to direct airflow for extended periods of time.
2 Due to the possibility of oxygen deficiency, ventilate the room when used together with stoves or other
heating devices.
3 Do not use this air conditioner for non-specified special purposes (e.g. preserving precision devices,
food, pets, plants, and art objects). Usage in such a manner could harm such property.
Cleaning and maintenance
1 Do not touch the metal parts of the unit when removing the filter. Injuries can occur when handling sharp
metal edges.
2 Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation, leading
to possible electric shock.
3 When cleaning the unit, first make sure that the power and breaker are turned off. The fan rotates at a
very high speed during operation. There is a possibility of injury if the unit’s power is accidentally
triggered on while cleaning inner parts of the unit.

Step 2
Prepare the hole in the wall so that the bottom of the housing is well
supported, the top has minimum clearance and the air inlet louveres have
clearance as shown. Holes from the outside through to the cavity should
be sealed. The housing should slope down towards the rear by about 5mm
to allow water formed during operation to drain.

Common
Issues
Common Problems and Solutions
Before calling for service, please review the following list of common problems and solutions.
The air conditioner is operating normally when:
• You hear a pinging noise. This is caused by water being picked up by the condenser on rainy days or in highly
humid conditions. This feature is designed to help remove moisture in the air and improve cooling efficiency.
• You hear the thermostat click. This is caused by the compressor cycle starting and stopping.
• You see water dripping from the rear of the unit. Water may be collected in the base pan in highly humid
conditions or on rainy days. This water overflows and drips from the rear of the unit.
• You hear the fan running while the compressor is silent. This is a normal operational feature.
The air conditioner may be operating abnormally when:

wait 3 minutes to restart the air conditioner to
prevent the compressor from overloading.
■Air flow is restricted.
・Make sure there are no curtains, blinds,
furniture or other obstacles in front of the air
conditioner.
■ The THERMOSTAT may not be
set cool enough.
• Turn the knob to a higher setting. The highest
setting provides maximum cooling.
■The air filter is dirty.
• Clean the filter at least every 2 weeks. Refer to
the Care and Maintenance section of the
manual.
■The air conditioner was just
turned on.
・After the air conditioner is turned on, you need
to give the air conditioner some time to cool the
room.
■Cold air is escaping.
・Check for open furnace floor resisters and cold
air returns.
■Cooling coils are iced up.
・See “Ice appears on the air conditioner” below.
■The cooling coils are iced over.
・Ice may block the air flow and obstruct the air
conditioner from properly cooling the room. Set
the fan at MED or HIGH while setting the
thermostat at 1 or 2 until the ice melts.
• CLOSE the air conditioner vent.
