Enter the Serial No. for a New Filter-Drier
The numerical keys on the keypad include
an alphabet that is used to enter the serial
number code for the new filter-drier. The
procedure is similar to text messaging. For
example,
To enter an “A”:
Press the 2 key once
to see the “2” on the
digital display; press
the 2 key again to
display the “A” .
To enter a “C”:
Press the 2 key once
to see the “2” on the
digital display; press
the 2 key three more
times to see the “C”
on the display.
After the appropriate letter is shown on the
display, pause for a moment until the cursor
moves to the next position.
Replace the Filter-Drier
The filter-drier is designed to trap acid and
particulates, and to remove water from refrigerant.
To meet the SAE J-2788 mandate for adequate
moisture and contaminant removal, the filter-
drier must be replaced after 150 lbs. (68 kg) of
refrigerant has been filtered.
Therefore, you no longer have a choice—the
filter-drier must be replaced. The unit gives a
warning when 100 lbs. of the filter capacity has
been used; the unit locks down when the 150
lb. filter capacity has been reached and will no
longer function. For this reason, always have a
spare Robinair No. 34724 filter-drier on hand.

drier has already been used in this unit.
