1-10. Location and Description of Major Components.

CONDITIONED AIR DISCHARGE GRILLE (1). Adjustable louvers allow directional control of conditioned air

INTAKE (RETURN) AIR GRILLES (2). Adjustable louvers allow control of outside (fresh) and return (from enclosure) air.

JUNCTION BOX NUMBER ONE (3). Contains circuit breaker (CB) relays (K1, K2, K7, K8 and K9) and terminal boards

(TB1 and TB2).

CONDENSATE WATER DRIP PAN AND DRAIN TRAP (4). The drip pan is located directly below the evaporator coil and

mist eliminator and is built into the casing. Its purpose is to collect condensate that drips off the evaporator coil and mist

eliminator during cooling operations. Condensate water then flows through tubing to the drain trap located inside the

lower front of the cabinet. The drain trap has a check valve that prevents air flow between the condenser and evaporator

sections through drain tubing.

COMPRESSOR (5). Pumps refrigerant through the system during cooling operations.

JUNCTION BOX NUMBER TWO (6). Contains fuses (F1, F2 and F3), transformer (T), relays (K6 and K10), rectifier (CR),

and filters (FL1, FL2, FL3 and FL4).

NOTE

The control panel is shown in its location when the air conditioner is installed as a

self-contained unit. The control panel is designed so that it may be removed from

the cabinet and installed in a remote location. See installation instructions (para

CONTROL PANEL (7) Contains a live position mode selector switch(s) and a temperature control thermostat (S1).
