Replacing the filter drier
The filter drier removes the moisture and suspended
particulate matter from the refrigerant. It is recom-
mended to change the filter drier after the specified
duration of usage. Reusing saturated filter driers may
result in reduced recycling capability of the ACS 151.
Consequently, the purity level of the refrigerant to be
charged to the vehicle A/C system also reduces.
i
The filter drier needs to be replaced after every
60 kg of refrigerant is recovered. When it is time to
replace the filter drier, the message "
Replacement Due
" is displayed before starting
vehicle A/C service.
As soon as the warning message is displayed, contact
customer service for ordering a new filter drier.
i
When inserting the new filter drier, ensure that it is
installed in the correct position.
