AIR CONDITIONER OPERATIONS AND PERFORMANCE

3 minutes protection function

3-minutes protection function prevents the air conditioner from starting for initial 3 minutes after the main power switch/circuit breaker is turned on for re-starting the air conditioner.

Power failure

Power failure during operation will stop the unit completely.

To restart the operation, push the START/STOP button on the remote controller.

Lightning or a wireless car telephone operating nearby may cause the unit to malfunction. Turn off the main power switch or circuit breaker and then turn them on again. Push the START/STOP button on the remote controller to restart.

Heating characteristics

Preheating operation

The air conditioner will not deliver warm air immediately after it is turned on. Warm air will start to flow out after approximately 5 minutes when the indoor heat exchanger warmed up.

Warm air control (In heating operation)

When the room temperature reaches the set temperature, the fan speed is automatically reduced to prevent to blow cold draft. At this time, the outdoor unit will stop.

Defrosting operation

If the outdoor unit is frosted during the heating operation, defrosting starts automatically (for approximately 2 to 10 minutes) to maintain the heating capacity.

The fans in both indoor and outdoor units will stop during the defrosting operation.

During the defrosting operation, the defrosted water will be drained from the bottom plate of the outdoor unit.

Heating capacity

In the heating operation, the heat is absorbed from the outside and brought into the room. This way of heating is called heat pump system. When the outside temperature is too low, it is recommended to use another heating apparatus in combination with the air conditioner.

Attention to snowfall and freeze on the outdoor unit

In snowy areas, the air inlet and air outlet of the outdoor unit are often covered with snow or frozen up. If snow or freeze on the outdoor unit is left as it is, it may cause machine failure or poor warming.

In cold areas, pay attention to the drain hose so that it perfectly drains water without water remaining inside for freeze prevention. If water freezes in the drain hose or inside the outdoor unit, it may cause machine failure or poor warming.

Air conditioner operating conditions

For proper performance, operate the air conditioner under the following temperature conditions:

Cooling

Outdoor temperature

: –5°C to 43°C

operation

 

 

Room temperature

: 21°C to 32°C (Dry valve temp.), 15°C to 24°C (Wet valve temp.)

 

 

 

 

CAUTION Room relative humidity – less than 80 %. If the air conditioner operates

 

in excess of this figure, the surface of the air conditioner may cause dewing.

Dry operation

Outdoor temperature

: 15°C to 43°C (Maximum suction air temp. 46°C)

 

 

 

 

Room temperature

: 17°C to 32°C

 

 

 

Heating

Outdoor temperature

: –15°C to 15°C (Wet valve temp.)

operation

 

 

Room temperature

: 15°C to 28°C (Dry valve temp.)

 

 

 

 

If air conditioner is used outside of the above conditions, safety protection may work.
