CORROSION PREVENTION AND CONTROL (CPC). Corrosion Prevention and Control of Army
materiel is a continuing concern. It is important that any water heater corrosion problems be reported so that
the problem can be corrected and improvements can be made to prevent the problem in the future. While
corrosion is typically associated with rusting of metals, it can also include deterioration of other materials, such
as rubber and plastic. Unusual cracking, softening, swelling, or breaking of these materials may be a corrosion
problem. If a corrosion problem is identified, it can be reported using SF 368, Product Quality Deficiency
Report. Use of key words such as "corrosion"'. "rust". "deterioration" or "cracking" will ensure that the
information is identified as a CPC problem. Send the form to: Commander, US Army Aviation and Troop
Command, Attn: AMSAT-I-MDO, 4300 Goodfellow Blvd., St. Louis, MO 63120-1798.
Section II. EQUIPMENT DESCRIPTION AND DATA
EQUIPMENT CHARACTERISTICS, CAPABILITIES, AND FEATURES.
The characteristics, capabilities and features described in this section apply to both
types of heaters unless otherwise indicated.
Characteristics, Capabilities and Features
Mounted on skid with forklift pockets
Provides 9 gallons of water per minute at 100°F
(37°C) temperature rise
Simple to set up, operate, and maintain
LOCATION AND DESCRIPTION OF MAJOR COMPONENTS. While the nomenclature of the
components for both types of heaters is similar, Figures 1-1 and 1-2 show the visual differences between the
M-80 and M-85 heaters, respectively.
Water Vessel. Contains water to be heated.
Temperature Limit Control Assembly. Consists of the operating and high limit controls. The operating
control regulates the burner to maintain water temperature between 100° and 210°F (370 and 980C). The high
limit control deactivates the fuel solenoid valve when water temperature exceeds 190°F (88°C).
