Operations and Performance IN Toshiba Air Conditioner Indoor Unit

Check before running

Check whether the earth wire is cut or disconnected.
Check whether the air filter is installed.
Turn on the circuit breaker 12 hours or more before starting operation.

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 ON / OFF 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 ON / OFF button on the remote controller to restart.

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.

Protective device

Stops operation when the air-conditioner is overloaded.
If the protective device is activated, the unit stops running, and the operation indicator and check indicator on the remote controller blink.

If the protective device is activated

Turn off the circuit breaker and perform a checkup. Continued running may cause a malfunction.
Check whether the air filter is installed. If not, the heat exchanger may be clogged with dust and water leakage may occur.

During cooling

The air intake or discharge of the outdoor unit is clogged.
Strong wind continuously blows against the discharge of the outdoor unit.

During heating

The air filter is clogged with a large amount of dust.
The air intake or discharge of the indoor unit is clogged.

Do not turn off the circuit breaker

During the air-conditioning season, leave the circuit breaker turned on, and use the ON / OFF key on the remote controller.

Attention to snowfall and freeze on the outdoor unit

In snowy areas, the air intake and air discharge 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 operation	Outdoor temperature : –15 °C to 43 °C (Dry bulb temp.)
	Room temperature : 21 °C to 32 °C (Dry bulb temp.), 15 °C to 24 °C (Wet bulb 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.
Heating operation	Outdoor temperature : –15 °C to 15 °C (Wet bulb temp.)
Heating operation	Room temperature : 15 °C to 28 °C (Dry bulb temp.)

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