PLAN THE WIRING
Interior Blower Installation
Exterior or In-Line Blower Installation
1. The Exterior or In Line Downdraft Blower system draws 6
AMPS and requires a 120 VAC, 60 Hz circuit.
2. The unit has a 18 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.
IMPORTANT - LOCATION OF ELECTRICAL OUTLET:
If Model DDEX30SS is being installed in a 30" wide
cabinet...
o r Model DDEX36SS is being installed in a 36" wide
cabinet...
o r Model DDEX48SS is being installed in a 48" wide
cabinet...
...the outlet cannot be located on the back
wall of cabinet.
In these cases, the width of the downdraft covers nearly
the entire width of the back wall of the cabinet. So you
must either:
• mount the electrical box to a side wall or cabinet floor
- at least 12 inches from the back wall.
• mount the electrical box to a wall stud behind the
cabinet - where it will not be covered by the down
draft. Then provide a clearance hole in the back wall
of the cabinet.
