SLAB MOUNT (HORIZONTAL UNITS ONLY) —
Provide a level concrete slab that extends a minimum of 6 in. (150
mm) beyond unit cabinet. Install a gravel apron in front of con-
denser coil air inlet to prevent grass and foliage from obstructing
airflow.
NOTE: Horizontal units may be installed on a roof curb if re-
quired.
ALTERNATE UNIT SUPPORT (IN LIEU OF CURB OR
SLAB MOUNT) — A non-combustible sleeper rail can be used
in the unit curb support area. If sleeper rails cannot be used, sup-
port the long sides of the unit with a minimum of 3 equally spaced
4-in. x 4-in. (102 mm x 102 mm) pads on each side.
Step 5 — Field Fabricate Ductwork
NOTE: Cabinet return-air static pressure (a negative condition)
shall not exceed 0.35 in. wg (87 Pa) with economizer or
0.45 in. wg (112 Pa) without economizer.
For vertical ducted applications, secure all ducts to roof curb
and building structure. Do not connect ductwork to unit.
Fabricate supply ductwork so that the cross sectional dimen-
sions are equal to or greater than the unit supply duct opening di-
mensions for the first 18 in. (458 mm) of duct length from the unit
basepan.
Insulate and weatherproof all external ductwork, joints, and
roof openings with counter flashing and mastic in accordance with
applicable codes.
Ducts passing through unconditioned spaces must be insulated
and covered with a vapor barrier.
If a plenum return is used on a vertical unit, the return should
be ducted through the roof deck to comply with applicable fire
codes.
A minimum clearance is not required around ductwork.
Step 6 — Rig and Place Unit —
Keep unit upright and do
not drop. Spreader bars are required for 08-14 size units; size 16
units do not require spreader bars. Rollers may be used to move
unit across a roof. Level by using unit frame as a reference. See
Table 2 and Fig. 10 for additional information.
Lifting holes are provided in base rails as shown in Fig. 10. Re-
fer to rigging instructions on unit.
Rigging materials under unit (cardboard or wood to prevent
base pan damage) must be removed PRIOR to placing the unit on
the roof curb.
When using the standard side drain connection, ensure the red
plug in the alternate bottom connection is tight. Do this before
setting the unit in place. The red drain pan can be tightened with a
1 /
2
-in. square socket drive extension. For further details see Step
11 — Install External Condensate Trap and Line on page 24.
Before setting the unit onto the curb, recheck gasketing on
curb.
NOTES:
1. SPREADER BARS REQUIRED FOR SIZES 08-14 — Top damage will occur if spreader bars are not used. Not required for size 16.
2. Dimensions in () are in millimeters.
3. Hook rigging shackles through holes in base rail, as shown in detail “A.” Holes in base rails are centered around the unit center of gravity. Use wooden
top to prevent rigging straps from damaging unit.
