period allows the indoor unit’s heat- exchanger to perform before emitting warm air. During defrosting (see page 13), the heating mode will be temporarily interrupted. DEFROST will be shown on the remote
controller display.
Cooling Always set the temperature lower than the current room temperature. If it is set higher than the current room temperature,
the unit will not enter the cooling mode and only the fan will operate.

Fan The room temperature cannot be adjusted in the FAN mode. (The room temperature is not displayed on the remote control-
ler.)

CARE AND MAINTENANCE

CAUTION!

Before cleaning the unit, be sure to stop the unit and disconnect the power supply. Turn off the electrical breaker. A fan operates at high speed inside the unit, and personal injury could result.

Installing the Air Filter

Be sure the filter is always installed in the inlet air grille of the indoor unit. Filters can be purchased through your local dealer.

Cleaning the Air Filter

If dirt is allowed to collect in the air filter, the airflow will be reduced, leading to reduced performance, and increased operation noise. Be sure to clean the filters regularly.
How to Cleaning

Use a vacuum cleaner to remove dust and dirt from the air filter, or wash in a synthetic detergent. After washing, dry in a shaded place, then reinstall.

When used for extended periods, the unit may accumulate dirt inside, reducing its performance. We recommend that the unit be inspected regularly, in addition to your own cleaning and care. For more information, consult authorized service personnel.
When cleaning the unit’s body, do not use water hotter than 40 °C, harsh abrasive cleansers, or volatile agents like benzene or thinner.

OPERATION DETAILS

Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle). Please read and understand the following details regarding this air conditioner.

Operation and Performance

  • Heating Performance
    This air conditioner uses a heat pump which absorbs heat from outside air and brings it indoors. As a result, its heating performance is reduced as the temperature of outside air drops. If you find that insufficient room heat is produced, we recommend that you use the air conditioner together with other heating appliances.
    Heat-pump type air conditioners use warm-air recirculation to warm your entire room. As a result, some time will be required after starting operation until your entire room becomes warm.

  • When Indoor and Outdoor Temperatures are High
    When both indoor and outdoor temperatures are high during use of the heating mode, the outdoor unit’s fan may stop at times.

  • Microcomputer-controlled Automatic Defrosting
    When the outside temperature is low and the humidity high, frost will collect on the outside unit, reducing heater efficiency. When this happens, the computer will automatically start the defrost cycle. During the defrost cycle, the indoor fan will shutdown and DEFROST will be displayed on the remote controller. It will take anywhere from 4 to 15 minutes before the air conditioner starts up again.
    Low Ambient Cooling
    When the outdoor temperature drops, the outdoor unit’s fans may switch to Low Speed, or one of the fans may stop intermittently.

AUTO Restart
In Event of Power Interruption Should the power supply to the air conditioner be inter-
rupted by a power failure, the air conditioner will restart automatically in the previously selected mode once the power is restored.
Temperature and Humidity Range

Use of other electrical appliances (electric shaver, etc.) or nearby use of a wireless radio transmitter may cause the air conditioner to malfunction. In this event, temporarily turn off the circuit breaker turn it on again and then use the remote controller to resume operation.

WARNING!

In the event of a malfunction (burning smell, etc.), immediately stop operation, turn off the electrical breaker, and consult authorized service personnel. Merely turning off the unit’s power switch will not completely disconnect the unit from the power source. Always be sure to turn off the electrical breaker to ensure that power is completely off.

Before requesting service, perform the following checks:

NORMAL FUNCTION

Symptom Noise is heard:

Problem

See Page

During operation and immediately after stopping the unit, the sound of water flowing in the air conditioner’s piping may be — heard. Also, noise may be particularly noticeable for about 2 to 3 minutes after starting operation (sound of coolant flowing).

  • During Heating operation, a sizzling sound may be heard occa-
    sional. This sound is produced by the Automatic Defrosting op- 13 eration.

Smells:

Some smell may be emitted from the indoor unit. This smell is the result of room smells (furniture, tobacco, etc.) which have — been taken into the air conditioner.

Mist or steam are emitted:

During Cooling, a thin mist may be seen emitted from the indoor unit. This results from the sudden Cooling of room air by the air — emitted from the air conditioner, resulting in condensation and misting.

  • During Heating operation, the outdoor unit’s fan may stop, and steam may be seen rising from the unit. This is due to Automatic 13 Defrosting operation.

Air flow is stops:

  • When Heating operation is started, fan is temporarily stop, to allow internal parts to warm up.

  • During Heating operation, if the room temperature rises above — the thermostat setting, the indoor and the outdoor unit will stop. If you wish to warm the room further, set the thermostat for a higher setting.

  • During Heating operation, the unit will temporarily stop operation (between 2 and 16 minutes) as the Automatic Defrosting mode operates. During Automatic Defrosting operation, DEFROST will 13 be shown on the remote controller display.

The fan may stop when the unit is monitoring the room’s tem-

perature.
