Air Conditioner Operations And Performance - Toshiba RAS-M10GDCV-E Owner's Manual

AIR CONDITIONER OPERATIONS AND PERFORMANCE

3-minutes protection function
3-minutes protection function prevents the air conditioner from starting for about 3 minutes just after the power
main switch/circuit breaker is turned on for re-starting the air conditioner.
Power failure
Power failure during operation will stop the unit completely.
• The OPERATION lamp on the indoor unit will start flashing when power is restored. (1 Hz)
• To restart the operation, push the START/STOP button on the remote controller.
• Lightning or a car wireless telephone operating nearby may cause the unit to malfunction. Turn off the power
main switch or circuit breaker and then to on them again. Push the START/STOP button on the remote
controller to restart.
Priority of Operation Types
Use the air conditioners by matching operation mode of the units in each room.
• For the indoor units in each room, different operation mode such as COOL and HEAT, DRY and HEAT
cannot be operated.
If operation type in a room differs from one in another room, priority is given to the
operation type in the room where operation has started previously.
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 warms up.
Warm air control
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 is started automatically (for approximately
5 to 10 minutes) to maintain the heating capacity.
• The fans in both of the 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 released 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 careful attention to the drain hose so that it perfectly drains water out 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.
