Cleanliness of this appliance is essential to good sanitation. Read and
follow all included cleaning instructions and schedules to ensure the
safety of the food product.

DO NOT submerge pre-lter or lter pack in water. Water will destroy
the lters leading to equipment shut-down.

Use only genuine Wells replacement parts and lters,

call [phone] or your authorized Wells service agent. Parts
supplied by others will void your warranty and may not provide safe
operation.

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-lter 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.

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

NOTE:

The GREASE BAFFLE
and FILTER PACK activate
mechanical switches, and
the PRE-FILTER activates a
vacuum switch, to verify that

the lter elements are in their
proper positions. All lter

elements must be properly

installed or the cooking

appliances will not be
energized. Also, the CHECK
FILTERS indicator will light.

IMPORTANT:

The lter hook prevents the
pre-lter 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.

Use only genuine Wells

replacement parts and lters,

call [phone] or your
authorized Wells service
agent. Parts supplied by
others will void your warranty
and may not provide safe
operation.

FILTERS INSTALLATION

1. FILTER PACK: Ships installed in the hood. If the lter pack is not in

position, the CHECK FILTERS indicator will light.
If the FILTER PACK becomes clogged, the REPLACE FILTER PACK
indicator will glow.

To install the FILTER PACK: Position the lter pack with the
charcoal portion UP. Slide the lter pack toward the rear of the unit
until it contacts the guides on the back panel. Push the lter pack UP
into the upper opening until it rests rmly against the lter pack seal.

When up in position, holder clips can be snapped over wall ledge on
each side. To remove FILTER PACK: Grasp both holder clips and pull

inward until the clips clear the sidewall ledge. Then, pull the lter pack

down and out.

2. PRE-FILTER: The PRE-FILTER ships in the FILTER FRAME. If the

PRE-lter is not in position, or if the PRE-FILTER is not in the FILTER

FRAME, the CHECK FILTERS indicator will light. If the PRE-FILTER
becomes clogged, the REPLACE PRE-FILTER indicator will glow.

To install the PRE-FILTER: Pay attention to the air ow markings. The

AIR FLOW arrow will point away from the installer. Slide the assembly

up into the front opening, behind the upper lter rail. While pressing

slightly against the bottom of the assembly, pull the FILTER HANDLE
toward you so as to engage the FILTER HOOK over the lip of the top

lter rail. Then lower and seat the assembly into the top indentation of
the lower lter rail.

3. GREASE BAFFLE: If the GREASE BAFFLE is not in place, the
CHECK FILTERS indicator will glow.

To install the GREASE BAFFLE: Slide the grease bafe up into the
indentation of the upper lter rail, then lower and seat it into the bottom
indentation of the lower lter rail. Pull toward you and downward to

verify the GREASE BAFFLE is properly seated in the lower frame rail.
