3. Determine the refrigerant volume based on
the following checks by looking through the
sight glass (inspection window) on the
receiver dryer.

This will make both high and low pressure
rise and exert a bad influence on the
pressure switch operation and the air
conditioning system.
(Figure (C): The refrigerant is insufficient.
Contact our authorized dealer/distributor for
recharge of the refrigerant.
