follow this warning can  
result in severe electrical  
shock.  
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.  
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

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  
in factory certified applications.

CAUTION:  
VENTILATOR OPERATION  
Hot Surface  
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 griddle will be energized. The roll warmer is  
energized at all times.  
Exposed surfaces can be hot  
to the touch and may cause  
burns.  
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 griddle. 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 griddle 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.

OPERATION (continued)  
CAUTION:  
GRIDDLE OPERATION  
Hot Surface  
PREPARING THE GRIDDLE SURFACE  
1. SEASONING STANDARD GRIDDLES  
a. Preheat the griddle surface to 375ºF (191ºC).  
b. Spread a light film of cooking oil over the entire griddle surface  
c. Allow the oil film to cook in for approximately 2 minutes, or until  
it smokes.  
Exposed surfaces  
can be hot to the touch  
and may cause burns.  
As manufactured, the steel  
surface of your Wells griddle  
has microscopic pores. It is  
important to fill these pores  
with oil in order to provide a  
hard, non-stick cooking  
surface.  
d. Wipe the griddle surface with a clean damp cloth until all oil is  
removed.  
e. For new griddles, repeat this procedure 2-3 times until the  
griddle has a slick, clean surface.  
2. CHROME PLATED GRIDDLES  
a. Thoroughly clean the griddle surface using a soft clean cloth  
and a small amount of mild detergent.  
b. Rinse and dry thoroughly after cleaning.  
c. The griddle is now ready to use.  
Because the microscopic  
pores in the griddle surface  
are filled by the chrome  
USING THE GRIDDLE  
plating, no seasoning of the  
griddle surface is required.  
1. Check the chart below for recommended cooking temperatures.  
Turn the temperature control knob to the desired temperature.  
The indicator light will glow while the griddle is heating. When  
the indicator light first goes out, the griddle is ready to use.  
IMPORTANT: SCRATCHES  
WILL DAMAGE THE  
SURFACE OF CHROME  
GRIDDLES!  
DO NOT use anything on this  
griddle that could scratch the  
surface.  
DO NOT clean chrome  
surface with griddle bricks,  
pumice stone or abrasive  
cleansers.  
2. For standard griddles, keep the griddle surface clean and well  
oiled during use. Scrape cooking waste into the grease trough  
frequently during use. Occasionally brush or spray a light coat of  
cooking oil on the griddle surface in order to maintain the non-stick  
surface.  
3. For chrome plated griddles, scrape cooking waste into the grease  
trough after preparing each order.  
DO NOT bang or tap pots,  
pans, spatulas or other metal  
utensils on chromed griddle  
surface as this may damage  
the chrome plating.

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.
