Specifications

You should 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 counter clockwise. (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 which 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. Once the new filter-drier is correctly installed. 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 2 minutes, and shut

off. The display will show the message "CPL".

This procedure automatically resets the and filter-drier change counter for another 200

pounds of refrigerant.

Important:

Do not remove

the filter-drier

from its sealed

bag until you are

ready to use it.
