CHAPTER 1
INTRODUCTION
Section I. GENERAL INFORMATION
1-1. Scope.
This manual is issued for the use of personnel who have the responsibility for service, operation and maintenance of the
Air Conditioner, Compact, Vertical, Model F60T-2 and F60T-2A, manufactured by Keco Industries, Inc., Cincinnati, Ohio;
Model CV-60-5/6-08, manufactured by Unifab Industries, Inc., Red Lion, Pennsylvania. Chapters 1 through 3 provide
information required for set-up, operation and servicing of the equipment by the operator. Chapter 4 contains detailed
maintenance instructions for the use of unit maintenance personnel. Chapters 5 and 6 provide detailed instructions for
repair and replacement of components authorized at direct support and general support maintenance levels.
1-2. Purpose.
The air conditioner provides ventilation by either circulating inside air or a mixture of inside and outside air, and is
equipped to utilize air passed through a chemical biological-radiological (CBR) filtering system if required. The air con-
ditioner also provides 60,000 Btu/Hr of cooling or 49,000 Btu/Hr heating, both of which are thermostatically controlled to
maintain desired comfort levels. During cooling operation, a percentage of dehumidification also occurs, the amount de-
pending upon the degree of humidity present in the atmosphere.
1-3. Special Limitations on Equipment.
The air conditioner is designed to operate at all ambient temperatures between -50 (-45.6 ) and 120F (48.9 ) as

This does not necessarily mean that a desirable comfort level can be maintained at extreme temperatures, since the
comfort level is dependent upon the heat loss or heat gain of the space to be heated or cooled, and upon whether such
heat loss or gain is within the capacity of the air conditioner to supply. When the air conditioner is stopped while in the
cooling mode, a period of one minute should be allowed to elapse before attempting to re-start. This period will permit
pressures to equalize so that the compressor will not encounter high head-pressures.
1-4. Maintenance Forms and Records.
Department of the Army forms and procedures used for equipment maintenance will be those prescribed by DA Pam
738-750, The Army Maintenance Management System (TAMMS).
1-5. Reporting Equipment Improvement Recommendations.
Equipment Improvement Recommendations (EIR's) can and must be submitted by anyone who is aware of an unsatis-
factory condition with the equipment design or use. It is not necessary to show a new design or list a better way to per-
form a procedure, just simply tell why the design is unfavorable or why a procedure is difficult. EIR's may be submitted
on SF 368. Mail directly to AMSAT-I-MDO, U.S. Army Aviation and Troop Command, 4300 Goodfellow Blvd., St.
Louis, MO 63120-1798. A reply will be furnished to you.
1-6. Difference Between Models.
There is no difference between Keco Model F60T-2, F60T-2A and Unifab Industries, Model CV-60-5/6-08.
