Prior to Operation
Prior to Operation
Preparing for Operation
1. Contact an installation specialist for installation.
2. Use a dedicated circuit breaker.
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). Such usage could damage the items.
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.

Care and Maintenance
Care and Maintenance
CAUTION
Before performing any maintenance, turn off the main power to the system.
You can do some of the periodic maintenance for your unit yourself; this includes cleaning air filters, cleaning unit
cabinet, clearing the condenser coil, and conducting a general unit inspection on a regular basis.
WARNING
Before removing access panels to service unit, disconnect power supply. Failure to disconnect power before attempting any
servicing can result in severe injury or death.
This product has anti-bacteria washable filters. It is very important to keep air filters clean in the central duct
system. Be sure to inspect them at least once each month when the system is in constant operation. (In new
buildings, check the filters every week for the first 4 weeks.)
Washable type filters can be cleaned by washing with a mild detergent and water. Ensure that the filters are
thoroughly dried before reinstalled them in the unit (or duct system).
Unfiltered air circulates through the unit's condenser coil and can cause the coil's surface to become clogged with
dust, dirt, etc.. To clean the coil, vertically (i.e., along the fins) stroke the coil surface with a soft bristled brush.
Keep all vegetation away from the condenser coil area.
Maintenance Performed by Serviceman-Cooling Season
To keep your unit operating safely and efficiently, the manufacturer recommends that a qualified serviceman
check the entire system at least once each year, or more frequently if conditions warrant. Your serviceman may
examine these areas of your unit:
1. Filters (for cleaning)
2. Motors and drive system components
3. Condenser coils (for cleaning)
4. Safety controls (for mechanical cleaning)
5. Electrical components and wiring (for possible replacement or connection tightness)
6. Condensate drain (for cleaning)
7. Inspect the unit duct connections to ensure they are physically sound and sealed to the unit casing.
8. Inspect the unit mounting support to see that it is sound.
9. Inspect the unit to ensure there is no obvious deterioration.
Maintenance Performed by Serviceman-Heating Season
Complete the unit inspections and service routines described below at the beginning of each heating season.
• Inspect the controller panel wiring to verify that all electrical connections are tight and that wire insulation is
intact.
Owner's Manual 25
Care and Maintenance
When the air conditioner is not going to be used for a long time.
When air conditioner is not going to be used for a long time.
1. Operate the air conditioner on air circulation mode for 2 to 3 hours.
• This will dry out the internal parts.
2. Turn off the circuit breaker.
CAUTION
Turn off the circuit breaker when the air conditioner is not going to be used for a long time. Dirt may collect and may cause a
fire.
When the air conditioner is to be used again.
1. Clean the air filter and re-install it in the indoor side.
On the fillter access panel at the left side of the unit, a “Filter access panel” label is attatched.
2. Check that the air inlet and outlet of the indoor/outdoor unit are not blocked.
Operation Tips
Do not overcool the room.
This is not good for your health and
wastes electricity.
Make sure that the doors
and windows are shut tight.
Avoid opening doors and windows
as much as possible to keep the
cool air in the room.
Keep blinds or curtains
closed.
Do not let direct sunshine enter the
room when the air conditioner is in
operation.
Clean the air filter regularly.
Blockages in the air filter reduce the
airflow and lower cooling and
dehumidifying effects.
Ventilate the room
occasionally.
Since windows are kept closed, it is
a good idea to open them and
ventilate the room now and then.
CAUTION
Before removing access panels to draw out air filters, disconnect power supply.
Since the fan rotates at high speed, it may cause a serious injury
❶ Clean at least once every month using a vacuum cleaner or washing with a neutral detergent in
lukewarm water.
❷ After washing with water, dry it well in the shade.
• Do not expose the air filter to direct sunlight or heat from a fire when drying it.
