Standard Specification for Dehumidifier, Shipboard, Mechanically Refrigerated, Self-Contained

ABSTRACT
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.
SCOPE
1.1 This specification covers self-contained dehumidifiers using hermetic refrigerant motor-compressors.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.3 The following safety hazards caveat pertains only to the test methods portion, Section 11, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3.1.4 Additions to the specification and supplementary requirements, if required.
4. Materials and Manufacture
4.1 In addition to the requirements cited in this specification, the dehumidifiers covered by this specification shall be designed,
constructed, assembled, and tested to comply with UL 474, UL 984, and ASHRAE Standard 15. In the event of differences between
any of the requirements of this specification and those of other referenced documents, the requirements of this specification shall
govern. The manufacturer shall certify compliance with the above standards for equipment furnished and shall be cited in the UL
Electrical Appliance and Utilization Equipment product directories.
4.2 The dehumidifier shall consist of a motor-compressor, condensing unit, dehumidifying coil, air-circulating fan, and
accessories, all enclosed within a metal cabinet. The dehumidifier shall be complete, self-contained with the refrigeration
equipment dehydrated, and charged with the necessary operating quantity of refrigerant and oil. Each unit shall be ready for
operation after removal of shipping protection, opening of valves where provided, and connection to electric power.
4.3 The motor-compressor shall be of the hermetic type and shall consist of a compressor and motor enclosed in a gastight shell.
The hermetic compressor unit shall conform to UL 984 and shall be at least ⁄6 hp. Equipment shall operate on 115-V, single-phase,
60-cycle alternating current. The unit shall be protected against overload by a thermal protector built into the motor. The thermal
protection shall be either the manual or automatic reset type.
4.4 Piping necessary for the satisfactory operation of the equipment shall be provided by the manufacturer. Tubing shall be made
of copper in accordance with Specification B280. Piping connections shall be arranged in such a manner so as not to impair the
vibration-isolation properties of absorption-type mounts, where such mounts are provided. Piping shall be securely supported to
minimize strain and vibration. Piping connections shall not be made of soft solder.
4.5 Materials used in the manufacture of the equipment shall be corrosion-resistant or treated to resist corrosion. The method
of manufacture shall not impair physical, structural, or corrosion-resistant properties of the components. Materials, coatings, and
paint systems shall satisfactorily pass the applicable salt spray and humidity test specified in this specification.
4.6 Bolts, nuts, studs, pins, screws, and such other fastenings or fittings shall be of a corrosion-resisting material, or of a material
treated in a manner to render it adequately resistant to corrosion. Screws exposed in final assembly shall be corrosion-resisting
material.
4.7 Similar parts, including repair parts, or corresponding apparatus furnished on the same contract or order, or built to the same
drawings, shall be strictly interchangeable without the necessity of further machining or hand fitting of any kind.
4.8 A plastic or other chemically inert container shall be provided for collecting the condensate. The container shall be of a size
and configuration that will fit within the cabinet enclosure. The container shall be provided with baffles to prevent the overflow
or spilling of water and shall be readily removable from the dehumidifier cabinet. A male fitting shall be provided from the
container for connection of a 0.375-in. (10-mm) inside diameter flexible rubber tubing for draining the condensate (wall thickness
0.125 in. (3 mm)). The rubber tubing will not be required to be furnished by the contractor.
4.9 Provision shall be made in the frame to permit securing the cabinet to any appropriate surface.
4.10 Identification plates shall be of a nonferrous metal or corrosion-resisting steel and shall conform to UL 474.

6.1.5 Each master drawing shall show outline, mounting, attachment, and connection dimensions, including methods and sizes
of fastenings and clearances for installation and servicing, plus supplementary data as necessary to permit installation without
suppliers assistance. The drawing shall illustrate design, construction, operation (or function), and identity of parts. Where
F1075 − 97 (2014)
acceptance tests are required, the tests shall be identified, and approval authority and date shall be noted on the drawing.
Subassembly drawings shall be provided to supplement master drawings where desirable.
6.2 Schematic Drawings:
6.2.1 Schematic drawings shall be provided that include all mechanical, piping and electrical circuits, and connections.
6.2.2 All symbols used for equipment components or parts shall be given a piece number and identified in the list of materials
