6 Removing Inlet Air Thermistor
a. The inlet air thermistor is fixed to the receiver PCB holder cover under the electrical box.
Its wire runs the back of the receiver PCB holder and enters into the electrical box from the opening for wires on
the bottom of the electrical box. Detach two catches on the back of the receiver PCB holder cover to dismount
the holder cover. Remove the thermistor fixed into two grooves on the receiver PCB holder cover.
b. When to attach inlet air thermistor, take the reverse steps of it. Care to not get the wire caught between the
receiver PCB holder cover and the receiver PCB holder. The risk runs of wire disconnection.
c. After attaching the thermistor, clamp the wiring for the expansion valve, freeze protection thermistor, gas pipe
thermistor and inlet air thermistor with 1 plastic band.
