Lifting Instructions
Greenheck’s Low-Profile Fan Coil (LFC) should be
lifted by the factory supplied lifting lugs or frame rails
and a spreader bar (by others) 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.
