CHANGING THE FILTER-DRIER
The filter-drier is specially blended to remove maximum moisture, acid, and
other contaminants. It will recycle about 300 pounds (136.07 kg) of refrigerant
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.
1. 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.
CAUTION! To prevent damage to the unit, the filter change
process should not be done with the unit connected to the
vehicle. Disconnect the unit by closing the service coupler valves
and disconnecting the high- and low-side hoses from the vehicle.
2. Select MAIN MENU , then press SCROLL MENU .
3. Press the FILTER CHANGE function key.
4. Press the START key. The unit will run to clear the filter-drier.
5. When clearing is complete, follow the on-screen prompts.
6. Turn the unit OFF, and disconnect the power cord from the power outlet.
WARNING
To prevent an electrical shock, disconnect the unit from the
power source before making repairs or replacements to
components.
7. Open the unit’s front panel, remove the old filter-drier, and replace it with
a new one. Hand tighten the new filter. Dispose of the used filter-drier
following current local, state, and federal laws.
8. Close the front panel door.
9. Plug the power cord into an appropriate power supply. Turn ON the main
power switch. The display will show the FILTER CHANGE mode. Follow
the on-screen prompts.
10. Press the START key. The unit will run briefly to pull an internal vacuum,
removing any air that entered the system during the changeover.
11. Press MAIN MENU to exit when the process is complete.
