5.7 Capacitor
• The capacitor is used to improve the rotational
power of the fan motors and compressor at
startup. The specification for each capacitor is
shown below.
5.8 Temperature Thermistor
• The evaporator inlet air thermistor (RTS) is
installed upstream of the evaporator, and
detects evaporator inlet temperature as a
resistance value.
• The freeze protection thermistor (CTS) is
installed in the evaporator outlet piping, and
detects low temperature on the evaporator as
a resistance value.
5.9 Drain Pump
• The drain pump evacuates evaporator
condensation accumulated in the drain pan.
The drain pump turns on when the compressor
turns on. The drain pump turns off when the
compressor turns off.
