CHANGING THE FILTER-DRIER
The filter-drier is specially blended to remove maximum moisture, acid and
other contaminants. It will recycle about 300 pounds (136.36 kgs) of refriger-
ant before a replacement is needed. The unit keeps track of jobs and total
recycled refrigerant, and signals when it’s time to change the filter-drier.
If the CHANGE FILTER message comes on during a job, it’s best to complete
that job before changing the filter-drier. FILTER CHANGE will show on the
display until the filter has been replaced.
