LOCATION AND DESCRIPTION
OF MAJOR COMPONENTS.
FABRIC COVER (1). Protects back or exposed side of the unit during periods of shut down. Must be rolled up
when operating in the cool mode or when fresh (outside) air is being used in any mode.
CONDITIONED AIR SUPPLY LOUVER (2). Provides directional control of conditioned air.
CONDITIONED AIR (EVAPORATOR) FANS (3). Draw the room or enclosure air in through the air filter and blow it
out over the heaters and evaporator (cooling) coil to supply conditioned air.
CONDITIONED AIR FAN MOTOR (4). Drives the conditioned air fans.
RETURN AIR LOUVER WITH FILTER CLAMPS (5). The recirculated air from the room or enclosure is drawn in
through this louver. The conditioned air filter, item 6, is mounted on clips on the inside of this louver.
CONDITIONED AIR FILTER (6). Filters room or enclosure air as it is recirculated.
RECTIFIER (7). Converts the transformer, item 8, output voltage from ac to dc for use in the control circuits.
TRANSFORMER (8). Reduces main line voltage down to control circuit voltage level.
GROUND CONNECTION POINT (9). Shelter or van electrical ground connection point.
INPUT POWER RECEPTACLE (PRIMARY LOCATION) (10). Connection point for main input power cable. See
item 15 for alternate receptacle.
CONTROL PANEL ASSEMBLY (11). Contains switches, controls and indicators for operating the air conditioner.
See items 12, 13 and 14 for a description of these switches controls and indicators.
ROTARY SWITCH (MODE SELECTOR) (12). Allows selection of unit operating mode.
POTENTIOMETER (TEMPERATURE CONTROL) (13). This control allows adjustment of the conditioned air
temperature while operating in the cool or heat modes.
LIGHT EMITTING DIODES (FAULT LIGHTS) (14). Help to indicate problem areas if the unit fails.
INPUT POWER RECEPTACLE (ALTERNATE LOCATION) (15). The main power cable may be connected here.
See item 10 for primary location. See installation instructions for switch-over instructions if this power receptacle is
CIRCUIT BREAKER (16). Located in the main electric line after the EMI filter. Provides circuit protection for the
REFRIGERANT SIGHT GLASS (17). Visually indicates the condition of the refrigerant flowing in the refrigerant
lines during cooling cycles when operating in the COOL mode.
HIGH REFRIGERANT PRESSURE CUTOUT SWITCH (18). This switch is factory set to shut the compressor off if
the refrigerant discharge line pressure rises to 470 to 490 psig (33.04 to 34.45 kg/cm2).
FRESH AIR VENTILATION GUARD (19). Screens and filters fresh air entering the unit.
CONDENSER GUARD (20). Protects the condenser from damage.
CHARGING VALVE, REFRIGERANT DISCHARGE LINE (HIGH PRESSURE) (21). Provides a connection point for
charging and checking discharge line pressure.
