evaporator fan section. A refrigerant sight glass and a filter drier are also con-

t a i n e d in this section. The fans draw ambient (outside) air through the compressor

section, over the condenser coil mounted in the condenser coil section, and exhaust

it to the outside. The sight glass provides a visual indication of the refrigerant

c h a r g e when the unit is operating. T h e filter drier removes foreign matter from the

liquid refrigerant as it passes through it.

Coil Section. The condenser coil is located in this section.

e. C o n d e n s e r

A m b i e n t (outside) air

is drawn from the compressor section by the condenser fans

i n t o and through the

condenser coil. T h i s action serves to change the refrigerant

f r o m a gaseous vapor

state into a liquid state.

f. C o m p r e s s o r S e c t i o n . The compressor section at the bottom of the five

s t a c k configuration, houses the motor compressor, magnetic starter and the high

p r e s s u r e cutout switch. The high pressure cutout switch stops the unit if the com-

p r e s s o r discharge pressure raises above 280 psig. Ambient (outside) air is drawn

i n t o and through the compressor section by the condenser fans mounted in the con-

denser fan section.
