PRECAUTIONS AND GENERAL INFORMATION

DANGER:BURN HAZARD

Contact with hot oil will cause severe burns. Always wear protective clothing and heat
resistant gloves when operating the fryer or filtering the oil.

WARNING: ELECTRIC SHOCK HAZARD

All servicing requiring access to non-insulated components must be performed by
qualified service personnel. DO NOT open any access panel that requires the use of
tools. Failure to heed this warning may result in severe electric shock.

CAUTION: BURN HAZARD

Contact with hot oil may cause burns.

line on frypot.

CAUTION:

RISK OF

DO NOT connect or

until all installation
instructions are read and
followed. Damage to the
appliance will result if
these instructions are not
followed.

NOTE: 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.

IMPORTANT:

DO NOT submerge pre-filter
or filter pack in water.

DAMAGE

NOTE: Fire suppression system and all associated components must

only be serviced by an authorized Ansul® Distributor. All setup,
charging, repair and/or adjustment of the fire suppression system must
be performed by an Authorized Ansul® Distributor ONLY.

IMPORTANT: If a remote pull station is installed, both rear casters (9)
must be replaced with legs to deter moving the unit. MOVING AN
APPLIANCE WITH A REMOTE PULL STATION WILL DISCHARGE
THE FIRE SUPPRESSION SYSTEM.

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 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
fryer appliance only. No other use of this product is recommended or

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.
