Operation GBF-2-GVH Ventless Fryer
When the [WASH/CHECK] lights turn ON , the E.A.C. Filter system has entered an alarm state and has stopped
functioning. After approximately two (2) minutes, a beeping tone alarm will begin to sound and shortly thereafter,
the [APPLIANCE POWERED] light will turn OFF and power to both Fryers’ heating elements will be shutdown.
The following steps may be tried in an attempt to clear the alarm:
1. Turn
OFF Hood Power Switch.
2. Remove the E.A.C. Cell and clean as described in Section 5.02.4.2 .
3. Inspect the Filter Cell for broken or missing ionizer wires, bent fins, or other damage. Ionizer wires are
replaceable (P/N 21153) ; bent fins may be straightened by hand. An excessively damaged Cell (broken
insulators, broken frame, etc.) will need to be replaced.
4. Inspect the Filter Contact Board inside Hood. Clean any grease accumulation away with a mild degreaser
solution (Simple Green) and dry thoroughly.
5. Replace Filter Cell ( see Section 5.02.2.3 ) and restart Hood. If the condition persist, contact a qualified service
technician and have the system evaluated and repaired.
