Section II EQUIPMENT DESCRIPTION
1-7. EQUIPMENT CHARACTERISTICS, CAPABILITIES, AND FEATURES.
a. The Model F18T-MPI Air Conditioner is designed to circulate, filter, and cool or heat air in the room or enclosure
in which it is installed.
b. The Model F18T-MPI has the capability of providing a maximum of 18,000 BTU/HR of cooling or 12,000
BTU/HR of heating. It is designed to automatically maintain the air in the room or enclosure at the desired temperature
selected on the control panel.
c. The unit is self-contained in a single cabinet that is ideally suited for van or shelter type installations. The only
external requirements are a source of 208 volt ac, 3 phase, 50/60 or 400 hertz input power, a suitable ground and an
entry to a suitable drain. The drain must be lower than the base of the cabinet, in its operating location, for disposal of
condensate waste water. It is designed to operate in almost any environmental condition from arctic to tropic and is fully
portable for movement from one location to another.
d. The primary installation requirement is that the exhaust air from the compressor/condenser section must be
vented to the outside atmosphere. This subject is fully covered in the installation instructions contained in Chapter 4,
"Unit Maintenance Instructions." e. When using this equipment in a secure area, caution must be exercised in meeting
the established electromagnetic radiation standards. These standards may limit the use of the equipment's remote
capability and require additional shielding for the ducts.
1-8. LOCATION AND DESCRIPTION OF MAJOR COMPONENTS.
CONDITIONED AIR (EVAPORATOR) FAN (1). Draws the room or enclosure air in through the air filter and blows it out
over the heaters and evaporator (cooling) coil to supply conditioned air.
HEATER ELEMENTS (2). Consists of six heating elements. The bank of heater elements warms the air from the
conditioned space as needed.
MIST ELIMINATOR (3). The purpose of the mist eliminator is to trap droplets of condensed water from the evaporator
coil, so that they will not be blown into the conditioned air space.
