Electric
Shock hazard
All servicing requiring
access to non-insulated
electrical components
must be performed by a
factory authorized technician.
DO NOT open any access
panel which requires the
use of tools. Failure to
follow this warning can
result in severe electrical
shock.

CAUTION:
Risk of
Damage
DO NOT connect or
energize this appliance
until all installation
instructions are read and
followed. Damage to the
appliance will result if
these instructions are not
followed.

NOTE: Fire suppression system and all associated components must
only be serviced by an authorized Ansul® Distributor. All setup,
charging, repair and/or adjustment of the fire suppression system must
be performed by an Authorized Ansul® Distributor ONLY.
IMPORTANT: If a remote pull station is installed, both rear casters (9)
must be replaced with legs to deter moving the unit. MOVING AN
APPLIANCE WITH A REMOTE PULL STATION WILL DISCHARGE
THE FIRE SUPPRESSION SYSTEM.
This Ventless Cooking System™ is designed to help reduce odor
emissions, but will not completely eliminate cooking odors. Air
exchange at the installation site must comply with the requirements of
the local jurisdictional authority. To ensure that odors do not build-up,
recommended minimum air exchange is 300 - 400 cfm of outside air
into and out of the area where the unit is used. Recommend use of
wall fan (GRAINGER # 4C707) and wall switch (Grainger #4C254), to
be supplied by user.
This appliance is intended for use in commercial establishments
only.
This appliance is intended to prepare food for human consumption.
No other use is recommended or authorized by the manufacturer or its
agents.
Operators of this appliance must be familiar with the appliance use,
limitations and associated restrictions. Operating instructions must be
read and understood by all persons using or installing this appliance.
Cleanliness of this appliance is essential to good sanitation. Read and
follow all included cleaning instructions and schedules to ensure the
safety of the food product.
Disconnect this appliance from electrical power before performing any
maintenance or servicing.
Do not splash or pour water on, in or over any exposed element,
control, control panel or wiring.

appliance has American sizes on all hardware.

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
cooktop 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
in factory certified applications.

OPERATION
CAUTION:

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 cooktop 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.

Hot Surface
Exposed surfaces can be hot
to the touch and may cause
burns.

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 cooktop. 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 cooktop 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.

Temperature Control

IMPORTANT:
The dial markings are an
INDICATION of temperature
only. The temperature of the
food product depends on
many factors, including the
size, shape and material of
the food container, and the
quantity and consistency of
the food
product.

HOTPLATE COOKTOP OPERATION
GENERAL OPERATIONAL NOTES
Carefully read the description of the hotplate operation on the
specification sheet.
DO NOT attempt to perform any maintenance or service unless the
hotplate is disconnected from electrical power.
DO turn the circuit breaker for the hotplate off before cleaning,
servicing or performing any maintenance.
DO NOT use sharp objects or metal implements to clean the heating
elements.
DO use a plastic spatula or plastic scouring pad to remove burned-on
food product.
OPERATION
Each heating element is controlled by an infinite switch
temperature control:
OFF removes power from the element
LOW thru 8 are temperature settings
Higher numbers indicate higher temperatures
There is a continuous range of settings between LOW and HI
HI is a continuous ON setting
The indicator light will glow any time the temperature control is on.
On ceramic cooktops, the HOT SURFACE indicator will glow any time
the control is on, or the surface is above 150ºF.
Cooking Recommendations:
Save energy by turning the temperature control off any time the
hotplate is not in use. The coil-type and ceramic heating elements will
provide full heat within 30 seconds, while solid plate heating elements
will reach full heat within 2 minutes, making it unnecessary to leave the
unit on during intermittent use.
Each heating element can hold up to a 16 quart pot or pan. For
efficient heating of food product, pots and pans should be no more than
10” in diameter.
Maximize the efficiency of solid elements and ceramic cooktops by
using flat-bottom pots and pans.
Stir thick liquids frequently to maintain a consistent temperature.

HEATING OPTIONS
1. Moist heat with Humitrol Rack:
a. MOIST operation prevents food from drying out as moisture, as
well as heat, is applied to the warming chamber.
b. To set for MOIST operation, remove Humitrol Rack from
bottom of drawer insert pan and carefully pour approximately 2
quarts of water (½” depth) into the pan. Reinstall rack.
c. The Humitrol Rack decreases the sloshing effect of the water
in the pan when the drawer is opened. When the drawer is
closed, the Humitrol Rack allows steam to rise through the
stored product in the drawer.
d. Place the food directly on the rack. The rack is designed to
support the food off of the steam vents, where water droplets
may form.
e. Check the water level in the pan periodically, and add water
when necessary.
f. Set the front air vent between fully closed and half-open.
Actual setting will depend upon the type and amount of product
stored in the drawer, the temperature setting, and the
frequency with which the drawer is opened.
2. Moist heat with pans:
a. This Wells warmer is designed to accommodate any
combination of standard-size, steam table pans.
b. Place a small amount of water in drawer pan. Place pans in
drawer pan.
c. Check the water level in the pan periodically, and add water
when necessary.
3. Dry heat:
a. For some applications, you may want to store previously
prepared foods in a dry-heat environment. To do so, place the
food directly into the empty (i.e. no water) drawer pan.

Exposed surfaces
can be hot to the touch
and may cause burns.
