Capacitor Capacitor
• The capacitor is used to improve the rota onal
power of the fan motor and compressor at
start up. The specifi ca on for each capacitor is
shown below.
Temperature Sensor
• Outlet temp sensor (TH1) is installed on top of
the evaporator, and detects evaporator outlet
temperature as a resistance value.
• Inlet temp sensor (TH2) is installed in front of
evaporator, and detects evaporator inlet tem-
perature as a resistance value.
• Ice temp sensor (TH3) is installed in the evaporator outlet piping, and detects
low temperature on the evaporator as a resistance value.
