Air Conditioner Operations And Performance - Toshiba RAS-18UFHP-ES Owner's Manual

AIR CONDITIONER OPERATIONS AND PERFORMANCE

Three-minute protection feature
A protection feature prevents the air conditioner from being activated for approximately 3 minutes when it is
restarted immediately after operation or when the power supply switch is set to on. This will protect the machine.
Heating characteristics
Preheating operation
The air conditioner will not deliver warm air immediately after it is started.
Warm air flows out after approximately 5 minutes when the indoor heat exchanger warms up.
(The PRE.DEF lamp is on during this intervals indicating the preheating operation.)
Warm air control
When the room temperature reaches the set temperature, the fan indoor speed is automatically reduced to
prevent a cold draft.
At this time, the outdoor unit will stop.
Defrosting
If the outdoor unit is frosted during heating operation, defrosting is started automatically (for approximately 5 to
10 minutes) to maintain the heating effect, and the PRE.DEF lamp is on.
• The fans in both the indoor and outdoor units stop during the defrost operation.
• During defrost operation, defrosted water is drained from the bottom plate of the outdoor unit.
Heating capacity
In the heating operation, heat is absorbed from outdoors and released into the room. That is called the heat
pump system. When the outdoor temperature is too low, to use another heating apparatus in combination with
the air conditioner is recommended.
Consideration for accumulated snow
Select the position for the outdoor unit where it will not be subjected to snow drifts, accumulation of leaves or
other seasonal debris. It is important that the air flow of the outdoor unit is not impeded as this will result in
reduced heating or cooling performance. During the heating mode, and at sub-zero temperatures, the water
drained off the outdoor unit as a result of the automatic defrost may accumulate and freeze. It is important that
adequate drainage or a soak-way is provided.
Power failure
Power failure during operation will stop the unit completely.
• The OPERATION lamp (green) on the indoor unit will start flashing when power is restored.
• To restart operation, push the START/STOP button on the remote control.
• Lightning or a car wireless telephone operating nearby may cause the unit to malfunction. Turn the power
supply switch to off and then to on. Push the START/STOP button on the remote control to restart.
Air conditioner operating conditions
For proper performance, operate the air conditioner under the following temperature conditions:
Cooling operation
Heating operation
Dry operation
If the air conditioner is used in conditions other than above, safety protection features may come into operation.
