XIII. HIGH-PRESSURE SWITCH
Located on the compressor hot gas line is a high-pressure
switch containing a Schrader core depressor. This switch
opens at 428 psig and closes at 320 psig. No adjustment is
necessary. Refer to Table 1.
XIV. LOSS OF CHARGE SWITCH
Located on the condenser liquid line is a low-pressure switch
which functions as a loss-of-charge switch. This switch con-
tains a Schrader core depressor. This switch opens at 7 psig
and closes at 22 psig. No adjustment is necessary. Refer to
Table 1.
XV. FREEZESTAT
Located on the “hair pin” end of the evaporator coil is a
bimetal temperature sensing switch. This switch protects
the evaporator coil from freeze-up due to lack of airflow. The
switch opens at 30 F and closes at 45 F. No adjustment is
necessary. Refer to Table 1.
