PRECAUTIONS AND GENERAL INFORMATION (continued)
OPERATIONAL NOTES:
REPLACE PREFILTER and REPLACE FILTER PACK indicator lights
provide a timely warning that a system shut-down is imminent.
The actual time between the indicator light coming on and the loss of
cooking appliance power will depend upon the cooking conditions.
Anytime a dirty PRE-FILTER is replaced, the system airflow will
increase. If the condition of the FILTER PACK is marginal, the
REPLACE FILTER PACK light could then come on. If this happens,
a fresh FILTER PACK must be installed within a reasonably short time.
Loss of airflow through the old filter pack will soon cause a system
shut-down when the airflow falls below minimum vapor capture levels.
KEEP A SPARE FILTER PACK ON HAND.
IMPORTANT: If you decide to “get the most” out of the old filter pack,
and continue to use it until a system shut-down happens, it is advisable
to have a fresh filter pack readily at hand, and have someone available
who is capable of replacing it. Otherwise, you may experience an
extended down time, with consequent associated loss of business.
The manufacturer assumes no liability for loss of business due to
a system shutdown caused by a dirty pre-filter and/or filter pack
(i.e. red SERVICE REQUIRED light is on), when the user fails to
have the proper replacement pre-filter and/or filter pack on hand.
The Ventless Cooking System™ hood is designed as part of a WELLS
cooking appliance only. No other use of this product is authorized by
the manufacturer or its agents. Wells Mfg. assumes no liability for the
use of this equipment with products by any other manufacturer’s, or for
use of this equipment with any Wells Manufacturing product other than

OPERATION
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 POWER switch to OFF, then back ON.
NOTE: Oven, griddle and hotplate will not operate unless the fire
suppression system is charged, and the ventilator section is operating .
CAUTION:

which control based on electrical current draw, not the actual
temperature of the hotplate surface.
2. Settings are OFF to
HIGH.
3. The associated
indicator will glow
when the switch is in
any position other
than OFF.
4. When set to HIGH, the
hotplate element can
reach maximum
temperature in
approximately 10
minutes.
5. Once liquid begins to boil, reduce the setting to minimize power
consumption and increase the useful life of the elements.
