4-5 AUTO RESTART FUNCTION
These models are equipped with an auto restart function. If you do not want to use
this function, please consult the service representative because the setting of the unit
needs to be changed.
When the indoor unit is controlled with the remote controller, the operation mode, the
set temperature, and the fan speed are memorized by the indoor electronic control P.C.
board. The auto restart function sets to work the moment the power has restored after
power failure, then, the unit will restart automatically. If the unit is operated in “I FEEL...”
or “AUTO” mode before power failure, the operation mode (COOL, DRY or HEAT) is not
stored in the memory. When the main power is turned on, the unit decides the operation
mode by the initial room temperature at restart and starts operation again.
Operation
1 If the main power (230V AC) has been cut, the operation settings remain.
2 When three minutes have passed after power was restored, the unit will restart
automatically according to the memory.
Notes:
The operation settings are memorized when 10 seconds have passed after the remote
controller was operated.
If the main power is turned off or a power failure occurs while AUTO START/STOP timer
is active, the timer setting is cancelled. As these models are equipped with an auto
restart function, the air conditioner starts operating with timer cancelled at the same
time that power is restored.
If the unit has been off with the remote controller before power failure, the auto restart
function does not work as the power button of the remote controller is off.
To prevent breaker off due to the rush of starting current, systematize other home
appliances not to turn on at the same time.
4-6 PIPE FORMING
Place the drain hose below the refrigerant piping.
Make sure that the drain hose is not heaved or snaked.
Do not pull the hose to apply the tape.
When the drain hose passes the room, be sure to wrap insulation material (obtainable
at a store) around it.
Wrap the felt tape 7 around the pipe and the drain hose, then put the pipe in the back
space of the indoor unit.
