PRECAUTIONS AND GENERAL INFORMATION (continued)

Fig. 4 Ventilator
Warning
Indicators

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.

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: Griddle and fryer will not operate unless the fire suppression
system is charged, and the ventilator section is operating .

OPERATION (continued)

GRIDDLE OPERATION

PREPARING THE GRIDDLE SURFACE

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.

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.

CAUTION:

HOT SURFACE

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

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.

Fig. 11 Hotplate
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.

GENERAL OPERATIONAL NOTES

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.

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.

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.

OPERATION (continued)

DRAWER WARMER OPERATION (when provided)

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:
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.

CAUTION:
