SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment can
be hazardous due to system pressure and electrical compo-
nents. Only trained and qualified service personnel should
install, repair, or service air-conditioning equipment.

Untrained personnel can perform basic maintenance func-
tions of cleaning coils and filters and replacing filters. All
other operations should be performed by trained service per-
sonnel. When working on air-conditioning equipment,
observe precautions in the literature, tags and labels
attached to the unit, and other safety precautions that apply.

Follow all safety codes. Wear safety glasses and work gloves.
Use quenching cloth for unbrazing operations. Have fire
extinguishers available for all brazing operations.

INSTALLATION

Unit is shipped in the vertical duct configuration. To convert to
horizontal configuration, remove screws from side duct open-
ing covers and remove covers. Using the same screws, install
covers on vertical duct openings with the insulation-side down.
Seals around duct openings must be tight. See Fig. 2.

Confirm before installation of unit that voltage, amperage
and circuit protection requirements listed on unit data plate
agree with power supply provided.

I. STEP 1 — PROVIDE UNIT SUPPORT

A. Roof Curb

Assemble and install accessory roof curb in accordance with
instructions shipped with curb. See Fig. 3. Install insulation,
cant strips, roofing felt, and counter flashing as shown. Duct-
work must be attached to curb, not to the unit. The accessory
thru-the-bottom 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-supplied

-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-bottom service con-
nections to the basepan in accordance with the accessory
installation instructions.

IMPORTANT:

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. 3. Improperly applied gasket can
result in air leaks and poor unit performance.

Curb should be level. Unit leveling tolerances are shown in
Fig. 4. This is necessary for unit drain to function properly.
Refer to Accessory Roof Curb Installation Instructions for
additional information as required.

WARNING:

Disconnect gas piping from unit when

leak testing at pressure greater than

1

/

2

psig. Pres-

sures greater than

1

/

2

psig will cause gas valve damage

resulting in hazardous condition. If gas valve is sub-
jected to pressure greater than

1

/

2

psig, it must be

replaced before use. When pressure testing field-
supplied gas piping at pressures of

1

/

2

psig or less, a

unit connected to such piping must be isolated by man-
ually closing the gas valve.

WARNING:

Before performing service or mainte-

nance operations on unit, turn off main power switch
to unit and install a lockout tag. Electrical shock could
cause personal injury.

CAUTION:

Ensure voltage listed on unit data plate

agrees with electrical supply provided for the unit.
