resistance value. These features are used as starting
device for the Motor.

PTC isn't cooled and a resistance value grows. As a result,
current can't flow to the sub- coil and the Motor can't operate

PTC is cooled and Compressor Motor performs normal

After the starting is over, the current in subcoil is cut off. The
proper features of PTC play all the above roles. So, PTC is
used as a motor starting device.

6) Note to Use PTC-Starter
(1) Be careful not to allow over-voltage and over-current.
(2) No Strike

4) Motor Restarting and PTC Cooling
(1) For restarting after power off during normal
Compressor Motor operation plug the power cord
Don't apply a forcible power or strike.
(3) Keep apart from any liquid.
