SAFETY CONSIDERATIONS

Installation and servicing 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.

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.

CAUTION: Ensure voltage listed on unit data plate agrees with electrical supply provided for the unit.

Unit is shipped in the vertical discharge configuration. To convert to horizontal configuration, remove screws from hor- izontal duct opening covers and remove covers. Using the same screws, install covers on duct openings in basepan of unit with the insulation-side down. Seals around duct open- ings must be tight. See Fig. 1.

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. 2. Install insulation, cant strips, roofing felt, and counter flashing as shown. Duct- work must be attached to curb, not to unit. If electric control power is to be routed through the basepan, attach the acces- sory thru-the-bottom service connections to the roof curb in accordance with the accessory installation instructions. Con- nection 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. 2. 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. 3. Refer to Accessory Roof Curb Installation Instructions for additional information as required.

B. Alternate Unit Support

When the curb or adapter cannot be used, support unit with sleeper rails using unit curb or adapter support area. If sleepers cannot be used, support long sides of unit with a minimum of three 4-in. x 4-in. pads, 2 at the unit’s corners and one at the center of gravity. If more than 3 are used, equally space out pads along unit side.

C. Slab Mount (Horizontal Units Only)

Provide a level concrete slab that extends a minimum of 6 in. beyond unit cabinet. Install a 6-in. gravel apron in front of outdoor-coil air inlet to prevent grass and foliage from obstructing airflow.

NOTE: Horizontal units may be installed on a roof curb if required.

II. STEP 2 — FIELD FABRICATE DUCTWORK

On vertical discharge units, secure all ducts to roof curb and building structure. Do not connect ductwork to unit. For hori- zontal applications, field-supplied isolation flanges should be attached to horizontal discharge openings and all ductwork attached to the flanges. Insulate and weatherproof all exter- nal ductwork, joints, and roof openings with counter flashing and mastic in accordance with applicable codes.
