t. Heater Assembly. The heater assembly (fig. 1-3) consists of six electrically operated CAL-ROD type heaters which
provide a total heating capacity of 10.5 kw or 35,000 BTU/hour. The heater assembly is mounted in the evaporator outlet
air stream so as to permit the evaporator fan to circulate ambient air over the heater assembly when the unit is in the
heating cycle. The heater assembly operates on 416-volt, 400-cycle, 3-phase power and consumes approximately 10.5
kw. The operation of the heater assembly is controlled by the return air thermostat and the setting of the controls on the
remote control box assembly.
u. Mist Eliminator. The mist eliminator (fig. 1-3) located between the evaporator assembly and the heater assembly,
is constructed of eight double layers of high tru-put herringbone mesh aluminum wire enclosed in a four by four mesh
aluminum wire cloth screen. The frame and drain channels are constructed of aluminum alloy. The mist eliminator
causes tiny water particles in the conditioned air stream (mist) to coalesce into water droplets sufficiently large to
precipitate within the mist eliminator. The precipitated water is collected in the mist eliminator drain channels; and then
flows into the air conditioner drain tube (fig. 1-3).
1-4. Identification and Tabulated Data
a. Identification. The air conditioner has five major identification plates (fig. 1-8). The U.S. Army plate (A) on the rear
of the air conditioner specifies the official nomenclature, including cooling capacity; Federal stock number; manufacturer,
part number, serial number and date; inspection date; and contract number and unit weight. The compressor motor
identification plate (B) located on top of the motor frame assembly specifies the manufacturer, part number, serial number,
stock number and Stratos part number; voltage, amperage, frequency and phase requirements; horsepower, and
rotational speed expressed in revolutions per minute. The compressor identification plate (C) on the upper face of the
compressor specifies the manufacturer, serial number and part number. The evaporator fan motor identification plate (D)
on top of the motor frame specifies the manufacturer, model number, serial number and frame number; voltages,
amperages, frequency and phase requirements; horsepower and duty ratings; and rotational speed expressed in
revolutions per minute. The condenser fan assembly identification plate (E) located on the fan shroud specifies the
evaporator manufacturer, model number, part number and aerial number; voltages, amperages, frequency and phase
requirements; horsepower and duty ratings, rotational speed expressed in revolutions per minute; and direction of fan
rotation and direction of air flow.
