HIGH PRESSURE SWITCH: The high pressure switch opens when the discharge line
pressure rises to 470 to 490 psig (33.041 to 34.447 kg/ cm2) to stop the compressor. This switch must
be manually reset after the line pressure drops to 320 psig (22.50 kg/ cm2).
AIR FILTER AND GRILLE: The air filter removes dirt and dust from the air that is to be
conditioned. The air falter is located behind the grille.
SENSING BULB: The sensing bulb senses the air temperature in the evaporator section to
maintain an even temperature of cooling air into the conditioned area.
