Usable on Code. The usable on code appears in the lower left corner of the description column heading.
Usable on codes are shown as UOC: in the description column (justified left) on the first line applicable item description
nomenclature. Uncoded items are applicable to all models. Identification of the usable on codes used in this RPSTL are:
Note: Parts coded 27Z are designed to be interchangeable with the older units. Order parts coded 27Z for all
units after existing stock is exhausted.
Note: For a combined narrative-RPSTL manual associated publications shall not be included.
Associated Publications. The publications listed below pertains to the Field Deployable Environmental
Control Unit and its components:
Operator, Unit, Direct Support and General Support Maintenance Manual
Fabrication Instructions. Bulk materials required to manufacture items are listed in the bulk material functional
group of this RPSTL. Part numbers for bulk materials are also referenced in the description column of the line item entry
for the item to be manufactured/fabricated. Detailed fabrication instructions for items source coded to be manufactured or
fabricated are found in TM 9-4120-411-14.
Assembly Instructions. Detailed assembly instructions for items source coded to be assembled from
component spare/repair parts are found in TM 9-4120-411-14. Items that make up the assembly are listed immediately
following the assembly item entry or reference is made to an applicable item.
Kits. Line item entries for repair part kits appears in a group in Section II (refer to Table of Contents).
Index Numbers. Items which have the word BULK in the figure column, will have an index number shown in
the item number column. This index number is a cross-reference between the National Stock Number/Part Number index
and the bulk material list in section II.
Illustrations - Listing. Illustrations in this RPSTL containing parts authorized at unit, direct support and general
support are identical to those published in TM 9-4120-411-14. Only those parts coded O, F or H in the third position of the
SMR code are listed in the tabular listing in section II; therefore, there may be a break in the item number sequence. Only
illustrations containing unit, direct support and general support authorized items appear in this RPSTL.
National Stock Numbers. National Stock Numbers (NSNs) that are missing from P source coded items have
been applied for and will be added to this TM by future change/revision when they are entered in the Army Master Data
File (AMDF). Until the NSNs are established and published, submit exception requisitions to: Commander, U.S. Army
Communications-Electronics Command and Fort Monmouth, ATTN: AMSEL-LC-MM, Fort Monmouth, NJ 07703-5007 for
the part required to support your equipment.
HOW TO LOCATE REPAIR PARTS
When National Stock Numbers or part numbers are not known:
First. Using the table of contents, determine the assembly group or subassembly group to which the
item belongs. This is necessary since figures are prepared for assembly groups and subassembly groups, and listings
are divided into the same groups.
Second. Find the figure covering the assembly group or subassembly group to which the item belongs.
