CAUTION:
HOT SURFACE
Exposed surfaces can be hot
to the touch and may cause
burns.
VENTILATOR OPERATION
1. Press the VENTILATOR POWER switch to ON. The green
VENTILATOR POWER light will glow and the blower fan will start.
After a short time, if all lters are sensed as being in position and
not clogged, the cooking appliance will be energized. The roll
warmer is energized at all times.
During normal operation, the VENTILA
TOR POWER light will be
the only light glowing on the upper control panel.
2. If the amber CHECK FILTER light glows, one or more lter elements is
out of position. Check the GREASE BAFFLE,
PRE-FILTER and FILTER PACK for proper installation in their
respective positions. Grease bafe and lter pack position are sensed
by mechanical switches. Pre-lter position is sensed by a
vacuum switch.
3.
When the amber REPLACE PRE-FILTER light glows, the pre-lter
is nearing the end of its service life. Replace the disposable PRE-
FILTER ELEMENT.
4.
When the amber REPLACE FILTER PACK light illuminates, the
HEPA / Charcoal lter pack is nearing the end of its service life.
Replace the lter pack.
Note:
The REPLACE PRE-FILTER and REPLACE FILTER PACK
lights are a warning that the indicated lter is near the end of its
service life. The appliance will continue to operate for a period of
time after the light glows to allow continued operation through a
peak period. However, the indicated lters must be replaced within
a reasonably short time period or they will clog and shut down
electrical power to the cooking appliance . The ventilator blower
will continue to run.
5.
When the red SERVICE REQUIRED light glows, either the
pre-lter or lter pack (or both) is clogged and can no longer pass
sufcient air to allow further operation. The ventilator fan continues
to run, but the cooking appliance is shut down until the underlying
clogged lter situation has been corrected. This can occur when
neither CHANGE...FILTER indicator light is lit, if both pre-lter and lter
pack are marginal. Replacing both the pre-lter and the lter pack
will remedy the situation.
NOTE: Replacing the pre-lter, even though not very dirty, will often
extend the service life of the more expensive lter pack.
Reset the unit by turning the VENTILA
TOR POWER switch to OFF,
then back ON.
6. A failure of incoming electrical power will cause a shut down of
the unit. After power is restored, reset the unit by turning the
VENTILATOR POWER switch to OFF, then back ON.
NOTE: Oven, griddle and hotplate will not operate unless the re
suppression system is charged, and the ventilator section is operating
