Cabinet Installation
The hood can be installed under a cabinet by supporting 
the hood from the top.
Note:
The cabinet must be structurally joined to the wall studs to 
support the weight of this hood.
Figure 14 shows the (4) screw holes labeled “K” used for 
mounting the hood to the bottom of the cabinet. Make sure 
both knockouts have been removed.
1.
In the base of the cabinet, drill 1/8” (3mm) tap holes 
(Dimension A in Figure 14 and in Table 2,). Screw in 
(4) 1" (25mm) screws (provided with hood) leaving 1/4” 
(6mm) exposed to hang hood on.
2.
If the hood is installed for vertical discharge, use 
Figure 14 to create clearance holes for passage of the 
transition and conduit (see Dimension B in Figure 8 
and in  Table 2 on the current page).
3.
For horizontal discharge, use Figure 9 on page 8  for 
the geometry of the cutout required for clearance of the 
transition.
4.
Hang hood from screws and tighten securely.
5.
From inside of hood, insert screws supplied. Drill 
through holes, use 5/8” (16mm) screws supplied, (1) on 
each side and (4) along the front, into bottom of the 
cabinet. See screw holes labeled "L" in Figure 14.

 ventilation hoods. All blower models 
1.
The blower is attached to the hood using weld studs 
provided on the mounting plate.
2.
Figure 15 shows the weld studs in location B for 
horizontal (rear) discharge. Attach (4) nuts (included 
with hood) to the weld studs. For vertical discharge, 
attach nuts to studs at the top of the mounting plate. 
3.
Guide the motor mounting plate over the studs and 
tighten nuts to secure the blower to the hood.
