Section 7 Component Check Procedures
FILTER-DRIERS
Function
To remove moister and particulates from the refrigerant.
This will prevent premature failure of the compressor and
blocking of restrictor devices.
Specification
The size of the filter-drier is important due to a critical
refrigerant charge. Using an improperly sized filter- drier
will cause the refrigeration system to be improperly
charged with refrigerant.
Driers are covered as a warranty part. The drier must be
replaced any time the system is opened for repairs. Refer
to the parts manual for the recommended OEM field
replacement drier.
Check Procedure
The drier should not alter the temperature of the
refrigerant. Compare the temperature of the copper pipe
either side of the filter/drier, they should be the same.
If there is a temperature drop that indicates a partial
blockage of the filter/drier and it should be replaced.
