THE FIRE SUPPRESSION SYSTEM.

This Ventless Cooking System™ is designed to help reduce odor
emissions, but will not completely eliminate cooking odors. Air
exchange at the installation site must comply with the requirements of
the local jurisdictional authority. To ensure that odors do not build-up,
recommended minimum air exchange is 300 - 400 cfm of outside air
into and out of the area where the unit is used.

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
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.
