FILTER SEAL O-RING REPLACEMENT
Inspect the filter seal O-rings located at the base of the filter cap for cracking or tearing. Perform the
following procedure if the O-rings are cracked or torn.
If the cap seal O-ring is cracked or torn, replace the entire filter cap.
Caution:
Do not attempt to remove the cap seal O-ring.
1. Using a plastic or wooden utensil (toothpick is ideal), lift filter seal O-ring out of groove then roll
the O-ring off the edge of the filter cap base as in Figure 7-4.

2. Roll the new O-ring over the edge of the filter cap base until it is seated in the appropriate
groove.
3. Make sure that the new filter seal O-ring is seated properly and not twisted. Lubricate the new
filter seal O-ring as described in Section D.
Note:
Do not use the filter cap with only one filter seal O-ring installed. This may cause splashing
during the dispersion phase and produce an insufficient seal for proper operation.
