This specification covers the performance requirements and corresponding test procedures for self-contained shipboard dehumidifiers that use hermetic refrigerant motor-compressors. The components of the dehumidifier, including the motor-compressor, condensing unit, dehumidifying coil, air-circulating fan, and accessories, shall all be enclosed within a metal cabinet. Dehumidifiers shall be evaluated by design capacity test, overload test, inclination test, and corrosion resistance test, and should operate satisfactorily as specified. Requirements for design documentation, schematic drawings, and manufacturer's manual are also considered.
