• Ensure that the drain trap is properly water-sealed.
- If the drain trap is modified, or is not water-sealed, the trap will not function
and a water leak may occur. Inject water into the hose during the periodic
check (six-monthly) to check water-sealing.
Warning:
For the operation with outdoor air, outdoor air may be directly supplied into
the room depending on the operation status. Control the room temperature
carefully.
Warning:
• Do not splash water over the unit and do not touch the unit with wet
hands. An electric shock may result.
• Do not spray combustible gas close to the unit. Fire may result.
• Do not place a gas heater or any other open-flame appliance where it will
be exposed to the air discharged from the unit. Incomplete combustion
may result.
• Never open the panel, except authorized technician. Rotating or high
voltage parts can cause injuries.
Warning:
• Do not remove the front panel or the fan guard from the outdoor unit
when it is running. You could be injured if you touch rotating, hot or high-
voltage parts.
• Never insert fingers, sticks etc. into the intakes or outlets, otherwise
injury may result, since the fan inside the unit rotates at high speed.
Exercise particular care when children are present.
• If you detect odd smells, stop using the unit, turn off the power switch
and consult your dealer. Otherwise, a breakdown, electric shock or fire
may result.
• When you notice exceptionally abnormal noise or vibration, stop
operation, turn off the power switch, and contact your dealer.

Caution:
• Do not direct the airflow at plants or caged pets.
• Ventilate the room frequently. If the unit is operated continuously in a
closed room for a long period of time, the air will become stale.

In case of failure

Warning:
• Never remodel the unit. Consult your dealer for any repair service.
Improper repair work can result in water leakage, electric shock, fire, etc.
• If the remote controller displays an error indication, the unit does not run,
or there is any abnormality, stop operation and contact your dealer.
Leaving the unit as it is under such conditions can result in fire or failure.
• If the power breaker is frequently activated, get in touch with your dealer.
Leaving it as it is can result in fire or failure.
• If the refrigeration gas blows out or leaks, stop the operation of the unit,
thoroughly ventilate the room, and contact your dealer. Leaving the unit
as it is can result in accidents due to oxygen deficiency.
When the unit is not to be used for a long time
• If the unit is not to be used for a long time due to a seasonal change, etc.,
run it for 4 - 5 hours with the air blowing until the inside is completely dry.
Failing to do so can result in the growth of unhygienic, unhealthy mold in
scattered areas throughout the room.
• When it is not to be used for an extended time, keep the [power supply]
turned OFF.
If the power supply is kept on, several watts or several tens of watts will
be wasted. Also, the accumulation of dust, etc., can result in fire.
• Keep the power switched ON for more than 12 hours before starting
operation. Do not turn the power supply OFF during seasons of heavy
use. Doing so can result in failure.

1.3. Disposing of the Unit

Warning:
When you need to dispose of the unit, consult your dealer. If pipes are
removed incorrectly, refrigerant (fluorocarbon gas) may blow out and come
into contact with your skin, causing injury. Releasing refrigerant into the
atmosphere also damages the environment.
