Maintenance
The HY-5G Steamer is designed for minimum
maintenance, and no user adjustments should be
necessary. Certain parts may need replacement
after prolonged use. If there is a need for service,
only authorized Groen representatives should
perform the work.
Always supply water with a low mineral count that
meets the standards outlined in the Water Quality
and Treatment section of this manual.
If steam or condensate is seen leaking from around
the door, take the following steps:
1. Check the door gasket. Replace it if it is cracked
or split.
2. Inspect the cooking chamber drain to be sure it
is not blocked.
3. Adjust the door latch pin to allow for changes
that might occur as the gasket ages.
a. Loosen the lock nut at the base of the latch
pin, then turn the latch pin ¼ turn clockwise,
and tighten the lock nut.
b. After adjustment, run the unit to test for
further steam leakage.
c. If there is still leakage, repeat the
adjustment.
d. Continue adjusting the pin clockwise until the
door fits tightly enough to prevent leakage.
The hinge may also be adjusted.
