be connected to the cooking
appliance contactor, the
control circuit of which is

appliances will provide no
protection in the event of a
fire, nor will cooking vapors
and odors be contained in
the event of ventilator hood
malfunction.

The ground lug of this
appliance must be connected
to a suitable building ground.

Contact a licensed electrician
to install and connect electrical
power to the appliance.
IMPORTANT:
Damage due to being

ELECTRICAL INSTALLATION

Refer to the nameplate on the ventilator. Verify ELECTRICAL
SERVICE POWER. Voltage and phase must match the nameplate
specifications, and available electrical service amperage must meet or
exceed the listed amperage. Refer to specifications listed on page 1
of this manual.
The ground lug of this ventilator must be connected to a suitable
building ground.
Remove the lower rear panel to access the cooking appliance
contactor and building alarm relay. Remove the appropriate knockout,
then wire the cooking appliance to the LOAD side of the contactor.
NOTE: If the provided power cord is not used, it is the responsibility
of the electrical contractor to provide suitable wiring, flexible or ridgid
conduit, and an appropriate strain relief.
The cooking appliance under the ventilator hood must be connected
to the LOAD side of the cooking appliance contactor, located in the
electrical connection box. The contactor functions control the cooking
applance in the event of ventilator malfunction or appliance fire.
The ventilator provides a dry contact relay connection for a building fire
management system. This pilot-duty relay may be required by local
fire codes, however, Wells Manufacturing strongly recommends that
such system be properly utilized in any case.
The alarm relay is activated by the Ansul® fire detection system. If the
installation includes a building alarm system, connect to either the N.O.
or N.C. contacts of the relay (as required by the building alarm system).
The ventilator will operate properly, and the control relay will be
energized, only when:
1. The VENTILATOR POWER SWITCH is "ON".
2. The Ansul® Fire Suppression System is charged and armed.
3. The grease baffle and filter pack are in position and serviceable,
and the ventilator pressure sensing system is satisfied.
