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 airow 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 airow through the old lter pack will soon cause a system shut-down when the airow 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. 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.

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 certied applications.

through an Authorized Wells Service Agency. See page 25.

2. The FIRE SUPPRESSION SYSTEM is comprised of a

pressurized cartridge & container of liquid re suppressant, with

associated plumbing and controls. It utilizes factory installed FUSIBLE LINKS for automatic actuation, and a factory installed MANUAL PULL STATION for manual actuation. Two NOZZLES are used

to disperse the liquid re

suppression media.

3. When the re suppression

system activates, the

re suppression media

is discharged, both the

cooking appliance and

the ventilator are deenergized, and a buzzer will sound continuously.

The re suppression media

will form an emulsion designed to both smother

and cool the re.

the lter elements are in their

proper positions.

All lter elements must be

properly installed or the

cooktop will not be energized.

Also, the CHECK FILTERS indicator will light.

IMPORTANT:

The lter hook prevents the

PRE-FILTER from being drawn in during operation. After installation, press against the top

of the lter frame to verify proper engagement of the lter hook over the lip of the top lter rail.

IMPORTANT:

Protect the surface of ceramic

cooktops from damage in the event a lter is accidentally

dropped. Use only genuine Wells 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.

OPERATION

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 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.

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 bafe 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 PREFILTER 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 cooktop. 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 sufcient air to allow further operation. The ventilator fan continues to run, but the cooktop 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.

CAUTION:

HOT SURFACE

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

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

specication 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 innite 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

efcient heating of food product, pots and pans should be no more than 10” in diameter.

Maximize the efciency of solid elements and ceramic cooktops by using at-bottom pots and pans.

Stir thick liquids frequently to maintain a consistent temperature.

DRAWER WARMER OPERATION

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.

CAUTION:

HOT SURFACE

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