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 condensate line trap and piping
8. Make electrical connections
9. Install other accessories
FRAME-MOUNTED INSTALLATION
Frame-mounted applications generally follow the sequence for
a curb installation. Adapt as required to suit specific installa-
tion plan.
Step 3 — Inspect Unit
Inspect unit for transportation damage. File any claim with
transportation agency.
Confirm before installation of unit that voltage, amperage and
circuit 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; see
Fig. 27. Do not remove carton until unit has been rigged and
locate in final position.
Step 4 — Provide Unit Support
ROOF CURB MOUNT
Accessory roof curb details and dimensions are shown in
Fig. 12-14. Assemble and install accessory roof curb in accor-
dance with instructions 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. 12-14. Improperly applied gasket can also result in air
leaks and poor unit performance.
Curb should be level. This is necessary for unit drain to func-
tion properly. Unit leveling tolerances are shown in Fig. 11.
Refer to Accessory Roof Curb Installation Instructions for ad-
ditional information as required.
Fig. 11 — Unit Leveling Tolerances
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 electric and control wiring is to be routed through the base-
pan, attach the accessory thru-the-base service connections to
the basepan in accordance with the accessory installation in-
structions.
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 ob-
structing 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, 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.
* Humidi-MiZer system is not available on 50TC*M models.
