NOTE:

-

If problem involving moisture in refrigerant circuit only occurs after a lengthy operating period or only infrequently (low pressure drops below
specification and evaporator ices up), it is sufficient to replace the dryer in the receiver Adjust quantity of refrigerant oil. Refrigerant circuit is then
to be evacuated for at least 3 hours.

-

It is not initially necessary to flush the refrigerant circuit with compressed air and nitrogen when this problem occurs since normally, there is only a
small quantity of moisture in the system which can be removed by lengthy evacuation.

-

With this malfunction, evaporator may ice up although quantity of refrigerant in circuit is 0K.
