Auto Restart Function - Mitsubishi Electric MS-GA60VB Series Installation Manual

Be careful not to make mis-wiring.
Firmly tighten the terminal screws to prevent them from loosening.
After tightening, pull the wires lightly to confi rm that they do not move.
If the connecting wire is incorrectly connected to the terminal block, the unit does
not operate normally.
If an earth is incorrect, it may cause an electric shock.

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.
