STEP 3 Slide the cabinet into the hole far enough to allow the guide-channel of the sill plate to contact the inside wall surface
(See Figure 15).
STEP 4 Drill three (3) 5/32" diameter pilot holes through holes in sill-plate into the framing and install three (3) #12 x 2" long screws
(Item #4) (See Figure15).
Instructions for mounting sleeve with slope must be observed to
prevent entry of water into room. Potential property damage can
occur if instructions are not followed.
Figure 15
NOTE: ALTERNATE FASTENERS WHICH MAY BE USED FOR SECURING THE SILL PLATE IN THE WALL, AND THE SUPPORT BRACKETS
TO THE OUTSIDE WALL ARE NOT FURNISHED, BUT ARE AVAILABLE AT A LOCAL HARDWARE STORE.
STEP 5 Drill two (2) 5/32" (4 mm) dia. pilot holes in each side at the locations shown (Figure 15) and install four (4) #12 x 2" screws
(Item #4). If the hole construction in Step 2 provides a sturdy mount with solid vertical studs, no support brackets are
required. The installation must support the weight of the unit plus an additional weight of 400 pounds (185 kg) on the rear of
the cabinet. The support brackets may be used for through-the-wall installations as shown in (Figure 15), for additional support.
STEP 6 If desired, trim around the cabinet on the room side with a suitable frame molding furnished by the installer (See Figure 15).
