Ground Level Preinstallation Details The ductwork must be placed into the roof curb before mounting the package unit. The unit should be set on a solid, level foundation, preferably a concrete slab at least 4" (10.2 cm) thick. The slab should be Roof Curb G 2009 ENV3 above ground level and surrounded by a graveled area for good drainage. Any slab used as a unit's foundation should not adjoin the building, since it is possible that sound and vibration may be transmitted to the structure. Rooftop Preinstallation Details Check that the roof is weathertight and allows proper drainage of condensation. Use steel or treated wood beams as unit support for load distribution. NOTE: To ensure proper condensate drainage, the unit must be installed in a level position. To avoid possible property damage or personal injury, the roof must have sufficient structural strength to carry the weight of the unit(s) and snow or water loads as required by local codes. Consult a structural engineer to determine the weight capabilities of the roof. The unit may be installed directly on wood floors or on Class A, Class B, or Class C roof covering material. To avoid possible personal injury, a safe, flat surface for service personnel should be provided. Rooftop Installation Roof Curb Installations Only Minimum Clearances NOTES: The unit is designed to be located outside the building with an Sufficient structural support must be determined prior to unobstructed condenser air inlet and discharge. Additionally, the locating and mounting the curb and package unit. unit must be situated to permit access for service and installation. Curb insulation, cant strips, flashing and general roofing material are furnished by the contractor. Condenser air enters from 3 sides. Air discharges upward from the top of the unit. Refrigerant gauge connections are made on Curbing must be installed in compliance with the National the right-hand side of the unit as you face the compressor Roofing Contractors Association Manual. compartment. Construct ductwork using current industry guidelines. Electrical connections can be made on the right-hand side of the unit. The best and most common application is for the unit to be located 10" (25.4 cm) from the wall (4" [10.2 cm] minimum) with the connection side facing the wall. This close-to-the-wall application minimizes exposed wiring. Close-to-the-wall application assures free, unobstructed air to the other 2 sides. In more confined application spaces, such as corners, provide a minimum 10" (25.4 cm) clearance on all air inlet sides. Allow 18" (45.7 cm) minimum for service access to the compressor compartment and controls. The top of the unit should be completely unobstructed. If the unit is to be located under an overhang, there should be a minimum of 36" (91.4 cm) clearance and provisions made to deflect the warm discharge air out from under the overhang. 3
