A.3.1 FEATURES

� Indoor (Main) Unit In case of PCH-P3GAH

1. AIR OUTLETNew PCH series models have 1 air outlet (auto vane switching of horizontal air flow / down flow by switched by autovane) instead of 2 (horizontal,and down flows).

2. EASY TO CLEAN ; FLOCKLESS VANEWith our original air current control mechanism, a flocklessvane is newly adapted.The flockless vane prevents the condensation on the vane.By changing the vane to the flockless type, the unit can becleaned much easier with mild household detergent.

3. NEW MATERIALS FOR BETTER OIL RESISTANCEWe have changed the materials of grille, filer, fan and fan casing from ABS toP.P. (polypropylene) for better oil resistance. As a result, oil crazing is cut inhaif.

4. SIMPLIFIED INSTALLATION WORK (DIRECT SUSPENDING METHOD)Simplified the installation work by changing the suspending method to the direct suspending method. (suspending the unitdirectly from the suspension fixture)In this way, the unit can be attached to the suspension fixture without removing the installation parts off (Only the sidecover is removed). This method is much simpler than the “One-time installation method”.

PCA-P2/P2.5/P3/P4/P5/P6GAPCH-P2/P2.5/P3/P4/P5/P6GAH[for wired remote controller]

Problem

Unit does not cool or heat very well.

The unit stops operating before arriv-ing at the set temperature in the heat-ing mode.

The air flow direction suddenlychanges.

A white mist is expelled from the in-door unit.

The indicators of the remote control-ler do not light up when operated.

Problem

CENTRALLY CONTROLLED is dis-played in the remote controller.

The start and stop functions are notavailable just after restarting the unit.

“H0” is displayed in the remote con-troller.

An error code is displayed in the re-mote controller.The operating display of the wirelessremote controller’s receiver is flash-ing.

Solution

The start and stop functions of the re-mote controller are not available whenthe CENTRALLY CONTROLLEDmessage is lit.

Wait about three minutes (operationhas stopped to prevent damage to theair conditioner).

An automatic startup test is being per-formed (will last for about two minutes).

A self-diagnostic function is being per-formed to preserve the air conditioner.∗ Do not attempt to make repairs your-

self. Turn the main switch off andcontact the dealer from whom youbought the air conditioner. Providehim or her with the name of the unitand the information displayed in theremote controller.

Solution

Clean the filter.

Frost forms when the outdoor tempera-ture is low and humidity is high. Wait forabout 10 minutes for the frost to melt.

After one hour of cooling-mode opera-tion with the air flow in a downward di-rection, the unit will automaticallychange to the “Horizontal air flow” mode.

When the unit is in the heating or de-frosting mode, it will automaticallychange to the “Horizontal air flow mode”.

This may occur just after the unit isturned on when a high level of humid-ity is present in the room.

Turn on the power switch. “ · ” will bedisplayed.

[for wireless remote controller (option)]

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 remotecontroller.

If none of the above apply, turn the main switch off and contact the dealer from whom you bought the air-conditioner, telling him the model name and the natureof the problem. Do not try to fix the unit yourself.

In any of the following cases, turn off the main power switch and contact your local dealer for service:• The operation lamp (on the main unit) flashes.• 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.

The following do not indicate any malfunction:Odours: smells such as tobacco or cosmetic odours may persist after they have been sucked into the unit.Sound of liquid flowing inside indoor unit: this can occur during or after operation and is simply the sound of refrigerant being circulated inside the unit.Ticking sound coming from indoor unit: this can occur when cooling or heating has just begun or has just stopped. It is caused by the indoor unit shrinking orexpanding slightly due to the change in temperature.The message “CENTRALLY CONTROLLED” appearing on the LCD panel: from time to time, this message may come up on the LCD panel. This does not indicateany malfunction.

Problem

Unit does not operate at all.

Problem

Unit does not start immediately.

Solution

Wait until the unit restarts automatically.The compressor may hesitate resum-ing because a three-minute resumeprevention circuit is incorporated in theoutdoor unit for protection of the com-pressor.

Solution

Turn main power on. Then press thePOWER ON/OFF button to turn theunit on.

Wait until power is restored, then pressthe POWER ON/OFF button to turn theunit on.
