ADJUSTMENT
1. COMPRESSOR (In A++ and A+ Models)
1) Role
The compressor intakes low temperature and low pressure
gas evaporated from E vaporator of the R efrigerator, and
condenses this gas to high temperature and high pressure
gas, and then plays delivering role to C ondenser.
2. PTC-STARTER (In A++ and A+ Models)
1) Composition of PTC-Starter
semiconductor starting device which uses ceramic
material and this material consists of B aTiO

.
(2) The higher the temperature is, the higher becomes the
resistance value. These features are used as starting
device for the Motor.
2) Role of PTC-Starter
(1) P TC is attached to Hermetic C ompressor used for
R efrigerator, S how C ase and starts Motor.
(2) C ompressor for household refrigerator applies to
single-phase induction Motor.

the above roles. S o, P TC is used as a motor starting
device.
2) Composition
The C ompressor is C omposed of C ompressor Apparatus
compressing gas, C ompressor Motor moving C ompressor
Apparatus and C ase protecting C ompressor Apparatus
and Motor. There is R elay Assembly (one set of
P TC S tarter and Over Load P rotector (OLP )) in
C ompressor. On the other hand, because the C ompressor
consists of 1/1000mm processing precision components
and is sealed after production in absence of dust or
humidity, deal and repair with care.
3) Note for Usage
(1) B e careful not to allow over-voltage and over-current.
(2) No S trike
If applying forcible power or strike (dropping or careless
dealing), poor operation and noise may occur.
(3) Use proper electric components appropriate to the
C ompressor.
(4) Note to K eep C ompressor.
If C ompressor gets wet in the rain and rust in the pin of
Hermetic Terminal, the result may be poor operation
and poor contact may cause.

4) Motor Restarting and PTC Cooling
C ompressor Motor operation, plug the power cord after
5 min. for pressure balance of R efrigerating C ycle and
P TC cooling.
(2) During normal operation of the C ompressor Motor, P TC
elements generate heat continuously. Therefore, if P TC
isn't cooled for a while after the power has been shut
5) Relation of PTC-Starter and OLP

times, P TC is cooled and C ompressor Motor performs
normal operation.
If OLP doesn't operate when P TC is not cooled,
C ompressor Motor is worn away and causes
OLP without fail.
6) Note to Use PTC-Starter
(1) B e careful not to allow over-voltage and over-current.
(2) No S trike
Don't apply a forcible power or strike.
(3) K eep apart from any liquid.
If liquid such as oil or water away enter the P TC , P TC
materials it may break due to insulation breakdown of
the material itself.
(4) Don't change P TC at your convenience.
Don't disassemble P TC and mold. If the exterior to the
P TC -starter is damaged, resistance value is altered
and it may cause poor starting of the compressor motor
