Jackson Dishmachine Component - Manual (Page 3)

6. Your repair kit comes with a new plunger. Examine the old one
and ensure that the mating surface is not damaged or cut. Also
inspect the rubber seal on the top of the plunger to ensure it is in
good condition and not torn.
7. If any of these conditions are present, replace the old plunger
with the new one from your kit. Verify that the new plunger is also
free from defects. If it is not, contact Jackson Technical Service
immediately.
8. The plunger should drop into the vacuum breaker and seat.
Ensure it is not flipped upside down (the orange seal ring should
be up towards the top of the vacuum breaker).
9. Pick up the cap and examine it. With a soft towel, remove any
grit, grime or debris that may have gotten caught in the threads of
both the cap retainer or the vacuum breaker body. There is an O-
ring that should be present on the cap retainer as well. Regardless
of the condition of the plunger, this O-ring should be replaced once
the cap is removed. Using a small flathead screwdriver, remove the
old O-ring.
10. With the new O-ring in place, screw the cap back on the vacu-
um breaker body. The cap needs to only be hand tight (snug).
AFTER MAINTENANCE ACTIONS
1. Reconnect the incoming water (if disconnected) and
turn on. Then restore power to the unit. Run the unit for at least 10
minutes to ensure there are no leaks. If any problems arise you
can contact Jackson Technical Service.
