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 SPARE FILTER PACKS 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.

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 co oktop. The ventilator blo wer 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 furthe r ope ration. 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 a nd 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 exp en sive 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

504 p/n 303903 opM WV-4H Ventless Hotplate Cooktop

unit. After power is restored, reset the unit by turning the VENTILATOR POWER switch to OFF, then back ON.

Fig. 10 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.

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 tempe rature 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.

OPERATION (continued)

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:
