• Do not stand on, or place any items on the unit.
• 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.
Caution:
• Do not use any sharp object to push the buttons, as this may damage the
remote controller.
• Never block or cover the indoor or outdoor unit’s intakes or outlets.
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.
• If you detect odd smells, stop using the unit, turn off the power switch and
consult your dealer.
• This air conditioner is NOT intended for use by children or infirm persons
without supervisions.
• Young children should be supervised to ensure that they do not play with
the air conditioner.
Disposing of the unit
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.

Caution:
• Always turn off the power, first on the remote controller and then the main

switch, before cleaning or servicing the unit.
• When installing or removing the filter or the intake grille, do not stand on an
unsteady surface. You may fall and injure yourself. Be also careful not to let
dust fall into your eyes.
Dirty or clogged filters block the airflow and reduce efficiency. Very dirty filters can
damage the air-conditioner itself.

3.1. Cleaning the filters and the indoor unit
Cleaning the filters
• Clean the filters using a vacuum cleaner. If y ou do not hav e a v acuum 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 120°F), as this may warp them.
• Make sure that the air filters are always installed. Operating the unit without
air filters can cause malfunction.
Cleaning the indoor unit
• Wipe the outside of the unit with a clean, dry, soft cloth.
• Clean off any oil stains or finger marks using a neutral household detergent (such
as dishwashing liquid or laundry detergent).
Caution:
Never use gasoline, benzene, thinner, scouring powder or any type of nonneutral detergent, as these substances may damage the unit’s case.

4. Troubleshooting
Before you call out a repair man, check the following table to see whether there is a simple solution to your problem.
Problem
Unit will not start.
Unit discharges air well, but fails to cool
or heat the room well.
Unit does not start immediately.
Unit stops soon after starting.
Pilot lamp does not turn on even when the
POWER ON/OFF button is pressed.
Remote controller shows that the unit is
operating.
Remote controller shows that the unit is
operating.
Remote controller check display reads
“CHECK P6” or “CHECK P8”.
Display reading
Cause
Main power switch is turned off.
Main power fuse has blown.
Outdoor unit’s ground fault break er is open.
A power cut has occurred (see NOTE be-
low).
Improper temperature setting - e.g. you
have selected COOL mode, but the desired
temperature setting is higher than the current room temperature.
Filters are clogged.
Outdoor unit’s intake or outlet is obstructed.
A door or window has been left open.
Unit is waiting three minutes before restart-
ing.
Indoor or outdoor unit’s intake or outlet is
obstructed.
Filters are clogged.
Solution
Turn main power on. Then press the
POWER ON/OFF button to turn the unit
on.
Replace the fuse.
Reset the ground fault breaker.
Wait until power is restored, then press
the POWER ON/OFF button to turn the
unit on.
Check the set temperature on the remote
controller and the actual intake air temperature. Use the COOLER and
WARMER buttons to set the temperature
as described in “Selecting a temperature”
on page 3.
Clean the filter and resume operation.
See “Cleaning the filters and the indoor
unit” on page 5.
Remove the obstruction.
Shut door or window.
Wait until the unit restarts automatically .
The compressor may hesitate resuming
because a three-minute resume prevention circuit is incorporated in the outdoor
unit for protection of the compressor.
Remove obstruction and restart the unit.
Remove the obstruction. Clean the filter
and resume operation.
NOTE: After a power cut, the unit will not restart automatically. You will have to restart it by pressing the POWER - ON/OFF button on the remote controller.
Wired remote controllers
In any of the following cases, turn off the main power switch and contact your local dealer for service:
• “CHECK” followed by “P1”, “P2”, “P3”, “P4”, “P5”, “P7” or “CENTRALLY CONTROLLED” is displayed on the control panel.
