HEATER ELEMENTS (1). Consists of six electrical resistance heaters mounted directly

behind the evaporator coil. The heater elements provide two ranges of heating.

E V A P O R A T O R COIL (2). Heat is absorbed from the air passing over the evaporator coil

by the refrigerant passing through it. This action serves to cool the air as it

flows through the evaporator coil.

T E M P E R A T U R E BULB (3). Senses air temperature over the evaporator coil to maintain

an even temperature of cooling air into the conditioned area.

E V A P O R A T O R FAN (4). The evaporator fan draws air through an air filter, over the

evaporator coil, and exhausts it into the conditioned area.

C O N T R O L PANEL (5). The control panel contains the manual thermostat control, the

fan speed switch, and selector switch for controlling cooling or heating tempera-

t u r e , fan speed, and mode of operation.

C O M P R E S S O R (6). A hermetically sealed electric motor driven compressor is used for

pumping refrigerant through the system.
