• 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.

2.5. Adjusting airflow direction

The vertical air vane helps select the vertical direction of the airflow.
1 Press AIR DISCHARGE button to select the vertical airflow direction.

• Each time you press the button, the option changes are displayed on the remote
controller, as shown below.

A (swing) → B → C → D → E → A

• In cooling/drying mode with the fan speed set to LOW, every press on the button
will change the direction in the order of A, B, D, A. (C can not be set)

• If D or E is set, the angle will automatically revert to B after one hour of operation.
(Do not use D and E too often in cooling/drying mode with the fan speed set to
LOW, or condensation or dripping can occur.)
F “AUTO RETURN” should be displayed.

• When the angle setting is C in cooling mode, switching the fan speed from HIGH
to LOW will cause the angle to revert to B automatically.

• The airflow direction can not be set with UP/DOWN while the SWING setting is being used.

• The arrow indicators are alternately displayed when the air sweep is in operation,

however they are not displayed when the air sweep is not in operation.

• The left/right guide vanes of PC(H) series and the guide vane of the PK(H) serises
can be changed manually.

■ PCH/PC Series

■ PKH/PK Series

Caution:

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

B

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.

■ PLH/PL Series

Intake grille removal

• Pull the knob on the intake grille in the direction indicated by the arrow and it

should open.

• Unhook the hinges to remove the intake grille from the grille.

Filter removal

• Open the intake grille.

• Release the knob on the center edge of the intake grille and pull the filter forward

to remove the filter.

3.1. Cleaning the filters and the indoor unit

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 dir ty, 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.

Display reading

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”.

Main power switch is turned off.

Main power fuse has blown.

Outdoor unit’s ground fault breaker is open.

A power cut has occurred (see NOTE be­low).

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 restart­ing.

Indoor or outdoor unit’s intake or outlet is
obstructed.

Filters are clogged.

Cause

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.

• The switches do not work properly.

• The circuit breaker trips frequently (or the fuse blows frequently).

• Water has accidentally been splashed into the unit.

• Water leaks from the unit.

• Something is accidentally dropped into the air-conditioner.

• An unusual noise is heard during operation.

Warning:
If the air conditioner operates but does not cool or heat (depending on model) the room, consult your dealer since there may be a refrigerant leak.
Be sure to ask the service representative whether there is refrigerant leakage or not when repairs are carried out.
The refrigerant charged in the air conditioner is safe. Refrigerant normally does not leak, however, if refrigerant gas leaks indoors, and comes into contact with the
fire of a fan heater, space heater, stove, etc., harmful substances will be generated.
