PLAN THE WIRING
1. This downdraft blower using the Flex Blower (purchase
separately) draws 3.0 Amps and requires a 120 VAC, 60 Hz
circuit. If using a remote blower (purchase separately), the
system draws 6.0 Amps (max.) and requires a 120 VAC, 60
Hz circuit.
2. The unit has a 30 in. long power cord with a 3-pronged plug.
Plan to provide a grounded outlet in a location which will allow
the unit’s power cord to reach.
3. Install electrical box according to local codes.
PREPARE THE DOWNDRAFT
Installations ducting through front panel opening only:
1. Place the downdraft on its back on a table or flat work surface.
2. Remove the HEX NUTS to remove the FRONT PANEL COVER.

PLAN CABINET CUTOUTS
!
CAUTION: BEFORE CUTTING HOLE IN CABINET
FOR DUCTWORK, check for interference with floor
joists, wall studs, electrical wiring, or plumbing.
Use the dimensions in the above illustration to help plan how and
where to provide duct access through your cabinet. Generally, 1-7/8"
x 19" rectangular duct will be used through left, right, and back of
cabinet - while 8" round duct will be used through cabinet floor.
For left, right, or rear exhaust:
Allow at least 18" for transition and elbow or blower.
For left / right exhaust:
A 30" deep cabinet is recommended to align properly with flex
blower. Flex blower can be mounted to rear cabinet wall or to a
platform / frame (not provided) on the base of the cabinet floor.
(See flex blower instructions).
Cabinet depths of 24" to 30" are required - depending on the
type of cooking appliance.
