INSTALLATION

Step 1 — Provide Unit Support

ROOF CURB — Assemble and install accessory roof curb in accordance with instructions shipped with this accessory. Accessory roof curb and information required to field fabricate a roof curb are shown in Fig. 1 and 2. Install insulation, cant strips, roofing and flashing as shown. Ductwork can be installed to roof curb before unit is set in place. Curb should be level. Unit leveling toler ance is ± l/16in. per linear ft in any direction. This is

necessary to permit unit drain to function properly. Refer to Accessory Roof Curb Installation Instructions for additional information as required.

ALTERNATE UNIT SUPPORT — When the curb cannot be used, support unit with sleepers using unit curb

support area. If sleepers cannot be used, support long

sides of unit with a minimum of 3 equally spaced 4-in. x 4-in. pads on each side.

Step 2 — Rig and Place Unit — Inspect unit for

transportation damage. File any claim with transporta

tion agency. Do not drop unit, keep upright. Use spreader

bars over unit to prevent sling or cable damage. Rollers

may be used to move unit across a roof Level by using unit frame as a reference; leveling tolerance is ± 1/16 in. per linear ft in any direction. See Fig. 3 for additional information. Unit weight is shown in Table 1.

Four lifting holes are provided in ends of unit base rails

as shown in Fig. 3. Refer to rigging instructions on unit.

POSITIONING — Provide clearance around and above unit for airflow, safety and service access (Fig. 4).

Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

Do not install unit in an indoor location. Do not locate unit air inlets near exhaust vents or other sources of contaminated air.

Although unit is weatherproof, guard against water from higher level runoff and overhangs.

ROOF MOUNT — Check building codes for weight dis

tribution requirements. Unit weight is shown in Table 1.

NOTE: Rig by inserting hooks into unit base rails as shown. Main tain a distance of 120 m. (3048 mm) from top of unit to eyehook. Use corner post from packaging to protect coil of unit from damage by rigging cable Use bumper boards for spreader bars.

CAUTION!

All panels must be in place when rigging.
