The unit must be mounted level. DO NOT mount the unit on a
slope. The drain pan has a built-in slope to ensure proper drainage.
Mounting the unit on a slope may result in improper drainage. For
threaded rod suspension see Fig. 5. Field-furnished and installed
accessories such as ductwork, mixing boxes, economizers, damp-
ers, etc. must be independently supported or suspended and must
not rely on the unit for support.

TOTAL WEIGHT UNIT CORRECTION FACTOR (LB)
See Fig. 6 and 7 for 8-row water-filled coils and double wall con-
struction (see Table 1). For a different number of rows, total unit
weight can be determined by:
1. Identify the size of unit and number of rows
2. From Fig. 6 or 7, identify the total weight of the unit
3. From Table 1, identify the correction factor and deduct this
factor from the total weight.
See Fig. 6 and 7 for operating weight information. Weight infor-
mation is based on 8-row water-filled coils and double wall cabi-
net construction. For a different coil and cabinet options, use the
weight correction factor table.
Table 1 — Total Unit Weight Adjustment
NOTES:
1. Unit weights (shown in pounds), ± 10%, are based on the largest
water-filled coil.
2. The operating weight information is based on 8-row water-filled
coils and double wall cabinet construction. For a different coil and
cabinet options, use the weight adjustment table.
