ROOF MOUNT
Check building codes for weight distribution requirements. Unit
operating weights are shown in Table 2.
Step 2 — Plan for Sequence of Unit Installation
The support method used for this unit will dictate different se-
quences for the steps of unit installation. For example, on curb-
mounted units, some accessories must be installed on the unit be-
fore the unit is placed on the curb. Review the following for rec-
ommended sequences for installation steps:
CURB-MOUNTED INSTALLATION
1. Install curb
2. Install field-fabricated ductwork inside curb
3. Install accessory thru-base service connection package
(affects curb and unit) (refer to accessory installation
instructions for details)
4. Prepare bottom condensate drain connection to suit
planned condensate line routing (refer to Install External
Condensate Trap and Line on page 15 for details)
5. Rig and place unit
6. Install outdoor air hood
7. Install flue hood
8. Install gas piping
9. Install condensate line trap and piping
10. Make electrical connections
11. Install other accessories
PAD-MOUNTED INSTALLATION
1. Prepare pad and unit supports
2. Check and tighten the bottom condensate drain connection
plug
3. Rig and place unit
4. Convert unit to side duct connection arrangement
5. Install field-fabricated ductwork at unit duct openings
6. Install outdoor air hood
7. Install flue hood
8. Install gas piping
9. Install condensate line trap and piping
10. Make electrical connections
11. Install other accessories
FRAME-MOUNTED INSTALLATION
Frame-mounted applications generally follow the sequence for a
curb installation. Adapt the sequence as required to suit specific
installation plan.
Step 3 — Inspect Unit
Inspect unit for transportation damage. File any claim with trans-
portation agency.
Confirm before installation of unit that voltage, amperage and cir-
cuit protection requirements listed on unit data plate agree with
power supply provided.
On units with hinged panel option, check to be sure all latches are
snug and in closed position.
Locate the carton containing the outside air hood parts. Do
not remove carton until unit has been rigged and located in fi-
nal position.
Step 4 — Provide Unit Support
ROOF CURB MOUNT
Accessory roof curb details and dimensions are shown in Fig. 4.
Assemble and install accessory roof curb in accordance with in-
structions shipped with the curb.
NOTE: The gasketing of the unit to the roof curb is critical for a
watertight seal. Install gasket supplied with the roof curb as shown
in Fig. 4. Improperly applied gasket can also result in air leaks and
poor unit performance.
Curb should be level. This is necessary for unit drain to function
properly. Unit leveling tolerances are shown in Fig. 5. Refer to
Accessory Roof Curb Installation Instructions for additional infor-
mation as required.
Install insulation, cant strips, roofing felt, and counter flashing as
shown. Ductwork must be attached to curb and not to the unit. The
accessory thru-the-base power and gas connection package must
be installed before the unit is set on the roof curb. If field-installed
thru-the-roof curb gas connections are desired, use factory-sup-
plied 1 /
2
-in. pipe coupling and gas plate assembly to mount the
thru-the-roof curb connection to the roof curb. Gas connections
and power connections to the unit must be field-installed after the
unit is installed on the roof curb.
If electric and control wiring is to be routed through the basepan,
attach the accessory thru-the-base service connections to the base-
pan in accordance with the accessory installation instructions.
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 condenser coil air inlet to prevent grass and foliage from
obstructing airflow.
NOTE: Horizontal units may be installed on a roof curb if
required.
ALTERNATE UNIT SUPPORT (IN LIEU OF CURB OR
SLAB MOUNT)
A non-combustible sleeper rail can be used in the unit curb sup-
port area. If sleeper rails cannot be used, support 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.
