M504 p/n 2M-303903 Owners Manual WV-4H Ventless Hotplate Cooktop

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.
