CS-MC12DKV CU-2C24DKV

Outdoor Unit
To protect compressor from reverse
rotation when there is a instantaneous
power failure.
60 Sec. Forced Operation Control
Once the compressor is activated, it
does not stop within the first 60 sec.
However, it stops immediately when
received stop signal from remote control.
Overload Protector
2-stage OLP to protect the compressor.
Overload Protector will trip when
Temperature of compressor increases
to 120 C.
High temperature or high current flows
to compressor.
