Ventless Hood System Introduction

Specific Precautions

Carbon monoxide poisoning will result from using this hood with any appliance
that utilizes combustible fuel. Use only electrical appliances with this hood.

In the event of an appliance fire, serious injury, property damage or death could
occur if the appliance is not properly secured to the hood. A restraining device
has been provided to assure that the appliance remains in the proper position
under the hood during normal operation. DO NOT REMOVE THE

RESTRAINING DEVICE!

Hood failure could result if the hood is operated without the grease baffle and
particle/odor filter installed. This is a special filter designed for this application
only; other filters will not work properly. Use only a BKI particle/odor filter.

Ventless Hood System Introduction

Approvals Information

Failure to adhere to building, fire and electrical codes during installation of this
unit could result in death, serious injury or property damage. The authority having
jurisdiction, such as the local building inspector or fire marshal, should be
consulted prior to installation to insure compliance with applicable codes.

In the event of an appliance fire, serious injury, property damage or death could
occur if the appliance is powered from a source other than the hood. The cooking
appliance used under this hood MUST receive its input power from the hood.
Electricity is automatically removed from the hood and the appliance when the
Fire Extinguishing System is activated.

In the event of an appliance fire, serious injury, property damage or death could
occur if the remote pull station is not properly installed. The remote pull is to be
clearly marked, located in a path of exit or egress and must comply with
applicable codes.

It is the responsibility of the owner to verify that the cooking appliance is eligible
for use with this hood.

This filter hood is an ETL Listed ductless hood for use with Listed commercial
cooking appliances only (griddle or fryer).

Fusible Links

• Fusible links to be UL Listed, 165° F., load rating 3-45 lbs.

Pressure/Open Fryers

• Pressure fryers acceptable for use with this hood shall be constructed such that when the lid is
released or unlatched it shall spring to the fully open position within four seconds. Fully open is
defined as vertical, upright position (80° or more) from the closed position. The lid must open
without operator or electrical assistance, toward the back of the hood.

• The lid of the pressure fryer, when it is open, shall not block fire-extinguishing nozzle from the vat.

• The lid of a pressure fryer should be checked for proper operation at least once a month. If the lid

fails to fully open when unlatched or released, it should be repaired immediately by factory
authorized service personnel. Do not operate a fryer with a defective lid opening mechanism.

• Fryers with lids (other than pressure fryers) shall be operated only with the lid removed. Lids may
be used for covering the vat when power to the cooking appliance and hood has been turned off.

Sandwich Grills

• Sandwich grills acceptable for use with this hood shall be used such that when the lid is either
fully open, released, or unlatched it shall spring to the fully open position. Fully open is defined as
vertical, upright position (80° or more) from the closed position. The lid must open toward the
back of the hood. The lid of a sandwich grill, when open shall not block fire extinguishing nozzles
from the cooking surface.

Ventless Hood System Operation

Operation

Principle of Operation

A blower inside the ventless hood draws cooking vapors through a grease baffle. Inside the baffle, the air
reverses direction two times capturing particles of moisture, grease, and dirt. Material collecting on the
baffle drains into the condensation trough located below the baffle. After air passes through the baffle, it
then enters a specially designed, high efficiency particle/odor filter where any particles that may have
passed through the baffle are trapped. A charcoal filter contained in this particle/odor filter helps to
remove cooking odors from the air. The filtered air then passes through the blower and is returned to the
room.

Preparation

The following conditions must be met for the Filter Hood to function:

• The particle/odor filter must be installed.

• The grease baffle must be installed.

• The filter door must be shut.

• The fire extinguisher system must be active.

• Power must be supplied to the hood.

• The fire damper must be open with link installed (see page 10).

Start-Up

To start the Filter Hood, press and hold the “START” button for three seconds. This is to insure that the
unit has achieved sufficient vacuum for the sensor to determine that the hood is in operation.
