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 airow 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.
Use only genuine Wells replacement parts and lters, call
(314) 678-6314 or your authorized Wells service agent. Parts supplied
by others will void your warranty and may not provide safe operation.
Loss of airow through the old lter pack will soon cause a system
shut-down when the airow falls below minimum vapor capture levels.
KEEP SPARE FILTER PACKS ON HAND.
IMPORTANT: If you decide to “get the most” out of the old lter pack,
and continue to use it until a system shut-down happens, it is advisable
to have a fresh lter 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-lter and/or lter pack
(i.e. red SERVICE REQUIRED light is on), when the user fails to
have the proper replacement pre-lter and/or lter 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

This appliance conforms to NSF Standard 4 for sanitation only if
installed in accordance with the supplied Installation Instructions
And operated and maintained in accordance with the instructions
in this manual.

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 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 lter elements is
out of position. Check the GREASE BAFFLE,
PRE-FILTER and FILTER PACK for proper installation in their
respective positions. Grease bae 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
sucient 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 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 re
suppression system is charged, and the ventilator section is operating
