CHANGING THE FILTER-DRIER
Change the filter-drier whenever refrigerant has been recovered from a burn-out
system or when the display shows the “CH-F” message (which means that the unit
has recovered 200 pounds of refrigerant since the last change). To change the filter/
drier follow these steps:
1. Press and hold SHIFT/RESET and then press FILTER. The compressor will
start and the display will show the messages “FIL” and “AUTOMATIC.”
2. The compressor will shut off when the vacuum switch trips, and the display
will show the messages “FIL” and “HOLD.”
3. Turn off the MAIN POWER switch and unplug the unit.
4. Remove the door access screws from the right side of the unit. Open the door.
5. Disconnect the hose from the top of the filter-drier, and unscrew the filter-
drier by rotating it counterclockwise. (You may need a 5/8" wrench to break
it loose.)
6. Open the new filter-drier, and generously lubricate the o-ring with vacuum
pump grease. Also lubricate the gasket in the end of the hose that connects to
the top of the filter-drier.
7. Replace the greased o-ring into the groove in the manifold. Screw the new
filter-drier into place. Reattach the hose with the greased gasket to the top of
the filter-drier.
8. Close the cabinet door, and replace the door access screws.
9. Turn on the MAIN POWER switch.
10. Press HOLD/CONT. The vacuum pump will start, the display will show the
messages “FIL AUTOMATIC,” the pump will run for about two minutes, and
then shut off. The display will show the message “CPL.”
This procedure automatically resets the filter-drier change counter for another 200
pounds of refrigerant.
CAUTION:
Do not remove
the new filter-
drier from its
sealed bag until
you are ready
to use it.
