Filter Change
The filter is designed to trap acid and particu-
lates, and to remove water from refrigerant.
To meet the mandate for adequate moisture
and contaminant removal, the filter must be
replaced after 150 kg (331 lbs.) of refrigerant
has been filtered.
The machine gives a warning when 125 kg
(276 lbs.) of the filter capacity has been used;
the machine locks down when the 150 kg
(331 lb.) filter capacity has been reached and
will no longer function.
Check Remaining Filter Capacity

Menu or when the machine prompts. The
machine displays

using the machine.
