OPERATION
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 filters are sensed as being in position and
not clogged, the cooking appliance will be energized.
During normal operation, the
VENTILATOR POWER light will be
the only light glowing on the upper control panel.
2. If the amber CHECK FILTER light glows, one or more filter
elements is out of position. Check the GREASE BAFFLE,
PRE-FILTER and FILTER PACK for proper installation in their
respective positions. Grease baffle and filter pack position are
sensed by mechanical switches. Pre-filter position is sensed by a
vacuum switch.
3. When the amber REPLACE PRE-FILTER light glows, the pre-filter
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 filter pack is nearing the end of its service life.
Replace the FILTER PACK.
Note: The REPLACE PRE-FILTER and REPLACE FILTER PACK
lights are a warning that the indicated filter 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 filters 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-filter or filter pack (or both) is clogged and can no longer pass
sufficient air to allow further operation. The ventilator fan continues
to run, but the cooking appliance is shut down until the underlying
clogged filter situation has been corrected. This can occur when
neither
CHANGE...FILTER indicator light is lit, if both pre-filter and
filter pack are marginal. Replacing both the pre-filter and the filter
pack will remedy the situation.
Note:
Replacing the pre-filter, even though not very dirty, will often
extend the service life of the more expensive filter pack.
Reset the unit by turning the
VENTILATOR 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 PO WER switch to OFF , then back ON .
NOTE: Griddle and fryer will not operate unless the fire suppression
system is charged, and the ventilator section is operating .
