Installing Heat Sink Insert:
If the heat sink insert moves or shifts during seal removal, remove and replace
with a new insert to prevent leakage.

2. Place seal plate face down on bench and use a short length of 1/2”
(13 mm) pipe to push insert out of seal.
3. Remove O-Ring from insert cavity in seal plate and discard.
NOTICE: Do not scratch O-Ring seat in seal plate.
Installation:
1. Clean heat sink insert cavity in seal plate, including O-Ring seat (step in
seal plate cavity - Figure 7).
2. Lubricate new O-Ring with petroleum jelly and insert into seat in seal plate
