15 Roof urb Installation Rigging Provisions for forks have been included in the unit base frame. No other fork locations are approved. Unit must be lifted by the four lifting holes located at the base frame corners. Lifting cables should be attached to the unit with shackles. The distance between the crane hook and the top of the unit must not be less than 60. Two spreader bars must span over the unit to prevent damage to the cabinet by the lift cables. Spreader bars must be of sufficient length so that cables do not come in contact with the unit during transport. Remove wood struts mounted beneath unit base frame before setting unit on roof curb. These struts are intended to protect unit base frame from fork lift damage. To remove the struts, extract the sheet metal retainers and pull the struts through the base of the unit. Refer to rigging label on the unit. Important: If using bottom discharge with roof curb, duct-work should be attached to the curb prior to installing the unit. Ductwork dimensions are shown in Roof urb Installation Instructions Manual. Refer to the Roof urb Installation A Instructions for proper curb installation. urbing must be installed in compliance with the National Roofing ontractors Association Manual. 30 Y RETURN Return Lower unit carefully onto roof mounting EVAPAT Evaporator oil OIL curb. While rigging the unit, the center of OMPRESS ompressor 1 1 gravity will cause the condenser end to G be lower than the supply air end. OMPRESS ompressor 2 2 Bring condenser end of unit into alignment SUPPLY Supply with the curb. With condenser end of the unit resting on curb member and using curb as a fulcrum, lower opposite end of the unit until entire unit is seated on the curb. When a rectangular cantilever curb B 49 X is used, take care to center the unit. heck for proper alignment and orientation of supply and return openings with duct. orner & enter-of-gravity Locations D Weight Types 7½-Ton Weights (lbs) 8½-Ton & 10-Ton Weights (lbs) Weight A Weight B Weight Weight D Shipping Weight Operating Weight To assist in determining rigging requirements, unit weights are shown to the right.

Proper unit installation requires that the roof curb be firmly and permanently attached to the roof structure. heck for adequate fastening method prior to setting the unit on the curb. Full perimeter roof curbs are available from the factory and are shipped unassembled. The installing contractor is responsible for field assembly, squaring, leveling, and mounting on the roof structure. All required hardware necessary for the assembly of the sheet metal curb is included in the curb accessory package. Determine sufficient structural support before locating and mounting the curb and package unit. Duct-work must be constructed using industry guidelines. The duct-work must be placed into the roof curb before mounting the package unit. Our full perimeter curbs include duct connection frames to be assembled with the curb. antilevered-type curbs are not available from the factory. ontractor furnishes curb insulation, cant strips, flashing, and general roofing material. Support curbs on parallel sides with roof 53¼ 1⅝ ¾ members. To prevent damage to the unit, the roof members cannot penetrate supply and return duct openings. Note: The unit and curb accessories are designed to allow vertical duct installation before unit placement. Duct installation after unit placement is not recommended. See the manual shipped with the roof curb for assembly and installation instructions. 1⅜ Top View Power and Low-Voltage Block Locations 16 SS-IGG7
