replacement after prolonged use. If there is a need
for service, only Groen personnel or authorized
Groen representatives should perform the work.
If steam or condensate is seen leaking from around
the door, take the following steps:
1. Check the door gasket. Use a 2" strip of paper
closed in between the door and the gasket. If the
paper is not snugly held in place, adjust the latch
pin as indicated in Step #3. Replace the gasket
if it is cracked or split.
2. Inspect the cooking chamber drain to be sure it
is not blocked.
3. Adjust the latch pin as follows:
a. Loosen the lock nut at the base of the latch
pin, and turn the latch pin ¼ turn clockwise.
Re-tighten the lock nut.
b. After adjustment, run the unit to test for
further steam leaks.
c. If there is still leakage, repeat the
adjustment.
d. Continue adjusting the pin clockwise until the
door fits tightly enough to prevent leaks.
