Mounting
1. Use the template (see
to cut the ceiling opening and determin-
ing the rod positions.
2. Install hanger bolts using 3/8" (10mm)
all-thread rod at the centers shown in
Table 3, Page 11.
3. Prepare the installation guides by fold-
ing the metal bracket by hand along the
perforations (Figure 7, Page 11).
4. Lift the cassette onto the hanging rods.
5. Level at the correct distance from the ceil-
ing with the aid of the installation guides
as shown in Figure 8, Page 12.
6. Secure the unit in position with locknuts
and washers on either side of the cassette
bracket.
7. Ensure threaded rod does not protrude
more than 2" (51mm) below the mount-
ing bracket (see Figure 9, Page 12).
NOTICE
If the ceiling is not level or even, it is
important that the cassette is installed
level to ensure correct pump operation
and to maintain fan clearances.
Place a carpenter's level on the unit.
A maximum slope of 1/8" (3mm) over
the length of the chassis toward the con-
densate drain is allowed.
Any slight discrepancy between the cas-
sette and ceiling will be taken up by the
fascia foam seal.
