INSTALL THE DUCTWORK
NOTE: To reduce the risk of fire, use only metal ductwork.
1. Decide where the ductwork will run between the hood and the
outside (Refer to Figure 1).
2. A straight, short duct run will allow the hood to perform most
efficiently.
3. Long duct runs, elbows, and transitions will reduce the performance
of the hood. Use as few of them as possible. Larger ducting may
be required for best performance with longer duct runs.
4. Install a roof or wall cap. Connect round metal ductwork to cap and
work back towards hood location. Use duct tape to seal the joints
between ductwork sections.

INSTALL THE HOOD
NOTE: the hood has to be installed, inside the cabinet, at minimum 1"
from the rear wall cabinet and at 3" from the front wall cabinet.
The internal height of cabinet has to be minimum 16" .
The hood should be mounted centered over the cook top burners.
1. Cut a hole in the bottom of the cabinet, using the dimensions shown
in Fig. 2.
2. Take off the (4) "A" screws and remove the metal grid (Fig. 3).
3. NOTE: For installations where the Power Pack is less than 30" above
cook top, it is recommended that the Power Pack be mounted into
a metal liner or non-combustible material. This will allow easier
cleaning and provide protection to the cabinetry (Fig.3A).
4. Insert the hood in the cabinet (Fig. 3) or metal liner (Fig. 3A) and
secure with the (4) "B" mounting sheet metal screws.
(Fig. 3 - wood bottom installation; recommended thickness 1/2"-
3/4").
(For alternate mounting, use machine screws with washers and
nuts. This alternate mounting method needs to be done prior to
installation of metal liner).
5. In the Non-Ducted Recirculation Configuration, install the Non-
ducted recirculation Filter before replacing the grid (see section
"Non-ducted recirculation filter installation").
6. Replace the grid after wiring is completed.

Ducted Configuration
1. Use 7" round metal duct to connect the discharge collar on the
hood to the ductwork above. An optional 7" round damper may be
used (purchased seperately).
2. Use duct tape to make all joints secure and air tight.
Non-Ducted Recirculation Configuration
1. Connect a 7" round metal duct to the discharge opening so that
the air is sent outside the cabinet and sent back into the room.

2. Use duct tape to make all joints secure and air tight.
NON-DUCTED RECIRCULATION
FILTER INSTALLATION
1. Remove the metal wires (Fig. 7) and discard them.
2. Install the Non-ducted recirculation Filter over the grease filter
and secure it with the metal wires supplied with the Non-ducted
recirculation Filter (Fig. 4).
WIRING
Note: This range hood must be properly grounded.
The unit should be installed by a qualified electrician in
accordance with all applicable national and local electrical codes.
Secure the conduit to the upper wiring hole through a conduit
connector.
Remove the (2) screws of the lateral wiring field cover and make
electrical connections. Connect both white leads to white supply lead
using suitable connector, connect black to black and green to green.
