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 cooking appliance will be energized.  
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 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.  
Fig. 9 Ventilator Indicator  
and Warning Lights  
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: Griddle and fryer will not operate unless the fire suppression  
system is charged, and the ventilator section is operating .

GRIDDLE OPERATION  
CAUTION:  
HOT SURFACE  
PREPARING THE GRIDDLE SURFACE  
Exposed surfaces can be hot  
to the touch and may cause  
burns.  
1. SEASONING STANDARD GRIDDLES  
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.  
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.  
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.  
NOTE:  
Standard griddles must be  
seasoned after every cleaning.  
IMPORTANT:  
SCRATCHES WILL DAMAGE  
THE GRIDDLE SURFACE!  
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.  
DO NOT bang or tap pots,  
pans, spatulas or other metal  
utensils on the griddle surface  
as this may damage the  
chrome plating.  
2. CHROME PLATED GRIDDLES  
Because the microscopic pores in the griddle surface are filled by  
the chrome plating, no seasoning of the griddle surface is required.  
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.  
USING THE GRIDDLE  
1. 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.  
2. For standard griddles, keep the griddle surface clean and well oiled  
during use. Scrape cooking waste into the grease tray 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  
tray after preparing each order.  
DO NOT bang or tap pots, pans, spatulas or other metal utensils on  
the griddle surface as this may damage the chrome plating.

GENERAL OPERATIONAL NOTES  
CAUTION:  
Hot Surface  
DO NOT use sharp objects or metal implements to clean the heating  
elements.  
Exposed surfaces can be hot  
to the touch and may cause  
burns.  
DO use a plastic spatula or plastic scouring pad to remove burned-on  
food product.  
OPERATION  
Indicator  
Light  
Each heating element is controlled by an infinite switch  
temperature control:  
Temperature  
Control  
(Infinite

LOW thru 8 are temperature settings  
Switch)  
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.  
Fig. 11 Hotplate  
Temperature Control  
COOKING RECOMMENDATIONS:  
Save energy by turning the temperature control off any time the  
hotplate is not in use. Spiral 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.  
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.  
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.

DRAWER WARMER OPERATION (when provided)  
HEATING OPTIONS  
Exposed surfaces  
can be hot to the touch  
and may cause burns.  
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.  
Fig. 9 Roll Warmer  
Temperature Control  
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.  
NOTE:  
The chart below is intended  
as a guide ONLY. Your own  
experience with this  
appliance, type of foods and  
method of operation will  
enable you to determine the  
temperature control and air  
vent settings best suited to  
your operation.  
3. Dry heat:  
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.
