OPERATION

About AUTO CHANGEOVER Operation

AUTO: ● When AUTO CHANGEOVER operation first selected, the fan will oper-

ate at very low speed for about one minute, during which time the unit detects the room conditions and selects the proper operating mode.

If the differance between thermostat setting and actual room temperature is more than +4 °F → Cooling

If the difference between thermostat setting and actual room temperature is within ±4 °F → Monitor operation If the difference between thermostat setting and actual room temperature is more than –4 °F → Heating operation

● When the air conditioner has adjusted your room’s temperature to near the thermostat setting, it will begin monitor operation. In the monitor operation mode, the fan will operate at low speed. If the room temperature subsequently changes, the air conditioner will once again select the appropriate operation (Heating, Cooling) to adjust the temperature to the value set in the thermostat.

(The monitor operation range is ±4 °F relative to the thermostat setting.)

● If the mode automatically selected by the unit is not what you wish, select one of the mode operation (HEAT, COOL, DRY, FAN).

About Mode Operation

Heating: ● Use to warm your room.

● When Heating mode is selected, the air conditioner will operate at very low fan speed for about 3 to 5 minutes, after which it will switch to the selected fan setting. This period of time is provided to allow the indoor unit to warm up before begin full operation.

● When the room temperature is very low, frost may form on the outside unit, and its performance may be reduced. In order to remove such frost, the unit will automatically enter the defrost cycle from time to time. During Automatic Defrosting operation, the OPERATION indicator lamp (red) will flash, and the heat operation will be interrupted.

Cooling: ● Use to cool your room. Dry: ● Use for gently cooling while dehumidifying your room.

● You cannot heat the room during Dry mode.

● During Dry mode, the unit will operate at low speed; in order to adjust

room humidity, the indoor unit’s fan may stop from time to time. Also, the fan may operate at very low speed when adjusting room humidity.

● The fan speed cannot be changed manually when Dry mode has been selected.

Fan: ● Use to circulate the air throughout your room.

During Heating mode:

Set the thermostat to a temperature setting that is higher than the current room temperature. The Heating mode will not operate if the thermostat is set lower than the actual room temperature.

During Cooling/Dry mode:

Set the thermostat to a temperature setting that is lower than the current room temperature. The Cooling and Dry modes will not operate if the thermostat is set higher than the actual room temperature (in Cooling mode, the fan alone will operate).

Each time the button is pressed, the air direction range will change as follows:

2 3 4 5 6 7

Types of Air flow Direction Setting:

1,2,3 : During Cooling / Dry modes 4,5,6,7 : During Heating mode 1,2,3,4,5,6,7 : During Fan mode

The remote Control Unit’s display does not change.

● Use the air direction adjustments within the ranges shown above.

● The vertical airflow direction is set automatically as shown, in accordance with

the type of operation selected.

During Cooling / Dry / Fan mode : Horizontal flow 1 During Heating mode : Downward flow 7

● During AUTO mode operation, for the first minute after beginning operation, airflow will be horizontal 1; the air direction cannot be adjusted during this period.

DANGER!

● Never place fingers or foreign objects inside the outlet ports, since the internal fan operates at high speed and could cause personal injury.

● Always use the remote control unit’s SET button to adjust the vertical airflow louvers. Attempting to move them manually could result in improper operation; in this case, stop operation and restart. The louvers should begin to operate properly again.

● During Cooling and Dry modes, do not move the vertical air direcion louvers outside their proper operating range for the mode (1 - 3) and into the fan region (4 - 7) ; using the louvers in the fan region will cause moisture to condense near the air outlet, and water may drop onto the floor. During the Cooling / Dry modes, if the louvers are operated outside the range 1 - 3 for more than 30 minutes, they will automatically return to position 3 range.

● When used in a room with infants, children, elderly or sick persons, the air direction and room temperature should be considered carefully when making settings.

TROUBLESHOOTING

WARNING!

Before requesting service, perform the following checks:

NORMAL

FUNCTION

Doesn’t operate immediately:

Noise is heard:

Smells:

Mist or steam are emitted:

Airflow is weak or stops:

Water is produced from the outdoor unit:

In the event of a malfunction (burning smell, etc.), immediately stop operation, disconnect the Power Supply Plug, 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 disconnect the Power Supply Plug or turn off your circuit breaker to ensure that power is completely off.

Symptom

● If the unit is stopped and then immediately started again, the compressor will not operate for about 3 minutes, in order to prevent fuse blowouts. Whenever the Power Supply Plug is disconnected and then re-

●

connected to a power outlet, the protection circuit will operate for about 3 minutes, preventing unit operation during that period.

● 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 operation, a slight squeaking sound may be heard. This is the result of minute expansion and contraction of the front cover due to temperature changes.

During Heating operation, a sizzling sound may be heard occasional.

●

This sound is produced by the Automatic Defrosting operation.

● 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.

● During Cooling or Dry operation, 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 Defrosting operation.

● When Heating operation is started, fan speed is temporarily very low, to allow internal parts to warm up.

● During Heating operation, if the room temperature rises above the thermostat setting, the outdoor unit will stop, and the indoor unit will operate at very low fan speed. 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 7 and 15 minutes) as the Automatic Defrosting mode operates. During Automatic Defrosting operation, the OPERATION indicator lamp will flash.

● The fan may operate at very low speed during Dry operation or when the unit is monitoring the room’s temperature.

● During SUPER QUIET operation, the fan will operate at very low speed.

● In the monitor AUTO operation, the fan will operate at very low speed.

● During Heating operation, water may be produced from the outdoor unit due to Automatic Defrosting operation.

TROUBLESHOOTING

Symptom

CHECK ONCE

If the problem persists after performing these checks, or if you notice burning smells, or the TIMER indicator lamp (Fig. 3 6) flashes, immediately stop operation, disconnect the Power Supply Plug, and consult authorized service personnel.

Doesn’t operate at all:

Poor Cooling or Heating performance:

The unit operates differently from the Remote Control Unit’s setting:

● Is the Power Supply Plug disconnected its outlet?

● Has there been a power failure?

● Has a fuse blown out, or a circuit breaker been tripped?

● Is the timer operating?

● Is the air filter dirty?

● Air the air conditioner’s intake grille or outlet port blocked?

● Did you adjust the room temperature settings (thermostat)

correctly?

● Is there a window or door open?

OPERATING TIPS

Operation and Performance

Heating Performance

● This air conditioner operates on the heat-pump principle, absorbing heat from outdoor air and transferring that heat indoors. As a result, the operating performance is reduced as outdoor air temperature drops. If you feel that insufficient heating performance is being produced, we recommend you use this air conditioner in conjunction with another kind of heating appliance.

● Heat-pump air conditioners heat your entire room by recirculating air throughout the room, with the result that some time may be required after first starting the air conditioner until the room is heated.

AUTO Restart

In Event of Power Interruption

● The air conditioner power has been interrupted by a power failure. The air conditioner will then restart automatically in its previous mode when the power is restored.

● Operated by setting before the power failure.

Microcomputer-controlled Automatic Defrosting

● When using the Heating mode under conditions of low outdoor temperature and high humidity, frost may form on the outdoor unit, resulting in reduced operating performance.

In order to prevent this kind of reduced performance, this unit is equipped with a Microcomputer-controlled Automatic Defrosting function. If frost forms, the air conditioner will temporarily stop, and the defrosting circuit will operate briefly (for about 7-15 minutes).

During Automatic Defrosting operation, the OPERATION indicator lamp (red) will flash.

●

If a power failure occurs during TIMER operation, the timer will be reset and the unit will begin (or stop) operation at the new time setting. In the event that this (kind of timer fault occurs the TIMER Indicator Lamp will flash (see Page. 3)).

● 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 disconnect the Power Supply Plug, reconnect it, and then use the Remote Control Unit to resume operation.
