8.1 Refrigerant filter replacement:
This unit is equipped with an electronic system that is capable of automatically performing all the phases required for filter repla-
cement, ensuring full safety for the operator without the help of technical staff.
When the filter counter has reached a calculated value of refrigerant recovered from vehicles, a message prompting the operator
to replace the filter is displayed for a few seconds upon activation. Before proceeding, new filter must be obtained through CTR’s
commercial network.
- Always replace filter each time the “Replace filter” message is displayed.
- Use only dedicated original spare parts. There are no compatible filters on the market.
- The “Replace filters” message warns you when the filters need to be replaced, but does not in any way lock
unit operation
. If you ignore the “Replace filters” message and continue using the unit, you may irreparably
compromise proper functioning of the unit and invalidate the warranty due to improper use
.
- Ensure that the used oil container is empty.
- Select “SERVICE” in the main menu.
- Move the cursor to “REPLACE FILTERS”.
- Close the HP and LP valves as shown on the display.

Press the “OK” button. The electronic system activates a procedure to release pressure from the filter and, when this has been
done, the message “REPLACE FILTERS” will be shown on the display. Do not switch the unit off
.
