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.

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.

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 use of this equipment with any Wells Manufacturing product other than

in factory certied applications.

2. Install the GREASE CUP on the right side of the unit, directly

below the grease trough.

OVEN RACK INSTALLATION

1. Install fan bafe. Use care around the fan. The blades are sharp.

2. Install one rack support on the fan bafe, and one rack support on

the left wall of the oven cavity.

3. Install racks as needed for the product being prepared.

OPERATION

VENTILATOR OPERATION

1. Press the VENTILATOR POWER switch to ON. The green VENTILATOR POWER light will glow and the blower fan will start.

After a short time, if all lters are sensed as being in position and not clogged, the cooking appliance will be energized. During normal

operation, the VENTILATOR POWER light will be the only light glowing on the upper control panel.

2. If the amber CHECK FILTER light glows, one or more lter elements is out of position. Check the GREASE BAFFLE, PRE-

FILTER and FILTER PACK for proper installation in their respective

positions. Grease bafe and lter pack position are sensed by mechanical switches. Pre-lter position is sensed by a vacuum

switch.

3. When the amber REPLACE PRE-FILTER light glows, the pre-lter

is nearing the end of its service life. Replace the disposable PREFILTER ELEMENT.

4. When the amber REPLACE FILTER PACK light illuminates, the

HEPA / Charcoal lter pack is nearing the end of its service life. Replace the lter pack.

Note: The REPLACE PRE-FILTER and REPLACE FILTER PACK

lights are a warning that the indicated lter 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 lters must be replaced within a

reasonably short time period or they will clog and shut down electrical

power to the cooking appliance . The ventilator blower will continue to

run.

5. When the red SERVICE REQUIRED light glows, either the pre-lter or lter pack (or both) is clogged and can no longer pass sufcient air

to allow further operation. The ventilator fan continues to run, but

the cooking appliance is shut down until the underlying clogged lter

situation has been corrected. This can occur when neither CHANGE...

FILTER indicator light is lit, if both pre-lter and lter pack are marginal. Replacing both the pre-lter and the lter pack will remedy the

situation.

Note: Replacing the pre-lter, even though not very dirty, will often

extend the service life of the more expensive lter 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 unit. After power is restored, reset the unit by turning the VENTILATOR POWER switch to OFF, then back ON.

NOTE: Oven, griddle and hotplate will not operate unless the re

suppression system is charged, and the ventilator section is operating.

CAUTION:

HOT SURFACE

Exposed surfaces can be hot to the touch and may cause burns.
