3. Thermistor (liquid pipe/gas pipe temperature detection)
4. Pressure sensor
*Special care must be taken when replacing heavy parts.
Work procedure Explanatory figure
(1) Remove the service panel.
1) For TH11, TH12, and TH15, refer to 1. 1)-2).
2) For TH16, refer to (1)-1.2.3. (GA type only)
(2) Remove the lead wire of the piping sensor from the
control board.
1) TH11,TH12 (CN10)
2) TH15,TH16 (CN11)
(3) Pull out the temperature sensor from the tempera-
ture sensor housing, and replace the temperature
sensor with the new one.
(4) Connect the lead wire of the temperature sensor se-
curely on the control board.
Work procedure Explanatory figure
(1) Remove the service panel.
1) For the pressure sensors PS1 and PS3, refer to 1. 1)-2).
(2) Remove the pressure sensor connector in trouble
from the control board, and insulate the connector.
1) Liquid-side pressure sensor (CNP1)
2) Intermediate-part pressure sensor (CNP3)
(3) Attach a new pressure sensor to the place which is
shown in the figure, and insert the connector to the
control board.
When gas leaks from the pressure sensor, repair the
leak, and follow the instructions above if required.
