Lifting Instructions

Greenheck's Modular Small Cabinet Fan (MSCF) should be lifted by the factory supplied lifting
lugs or frame rails and a spreader bar to prevent damage from occurring to the equipment (see
figure 1). Avoid twisting or uneven lifting of equipment. Do not lift equipment by coil connections
or headers. The unit must remain upright during lifting. All access doors and panels must be
closed during lifting to avoid damage (see figure 1).
