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 may 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 discharge configuration. To

convert to horizontal configuration, remove screws from side

duct opening 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. If gas or electrical connections

are to be routed through the curb, attach the accessory thru-

the-curb service connection plate to the roof curb in accor-

dance with the accessory installation instructions. Connec-

tions must be installed before unit is set on roof curb.

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

also result in air or water 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.

If gas or electrical connections are to be routed through the

bottom of the unit, attach accessory thru-the-bottom service

connections to the basepan in accordance with the accessory

installation instructions.

CAUTION: Ensure voltage listed on unit data plate

agrees with electrical supply provided for the unit.

WARNING: Disconnect gas piping from unit when

leak testing at pressure greater than

psig. Pres-

sures greater than

psig will cause gas valve damage

resulting in hazardous condition. If gas valve is ever

subjected to pressure greater than

psig, it must be

replaced before use. When pressure testing field-

supplied gas piping at pressures of

psig or less, a

unit connected to such piping must be isolated by man-

ually closing the gas valve(s).

WARNING: Before performing service or mainte-

nance operations on unit, turn off main power switch

to unit and install lockout tag. Electrical shock could

cause personal injury.
