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.
Open the front control panel to access the cooking appliance contactor.
Wire the cooking appliance control circuit to the terminal block per the
figure below.
NOTE: It is the responsibility of the electrical contractor to provide
suitable wiring, flexible or rigid conduit, and an appropriate strain relief.
Electrical Connection
NOTE: The hood requres a single phase (1ph), 208 or 240 volt, 15
amp suppy. When connecting line voltage to the unit's terminal block,
use a minimum of #12 gage copper wire only, suitable for 167°F (76°C)
ambient temperature.
Appliance Connections
All under hood appliances are required to be interlocked with the hood's
equipment cut-off circuit, through a customer supplied contactor. This
contactor must be a UL listed, definite purpose AC resistive air heating type,
suitable for the appliance load. Installation and connections shall be in
accordance with the National Electric Code NFPA 70. These connections
provide an automatic shutdown of the appliance when the hood is OFF, or in
