1) Definition of OLP
(1) OLP (OVER LOAD PROTECTOR) is attached to the

Hermetic Compressor and protects the Motor by cutting
off current in Compressor Motor in case of over-rising
temperature by Bimetal in the OLP.

(2) When over-voltage flows to Compressor motor, the

Bimetal works by heating the heater inside the OLP, 
and the OLP protects Motor by cutting off current which
flows to the Compressor Motor.

2) Role of the OLP
(1) The OLP is attached to the Hermetic Compressor used

for the Refrigerator and Show Case and prevents the
Motor Coil from being started in the Compressor.

(2) Do not turn the Adjust Screw of the OLP in any way for

normal operation of the OLP.
