Part name
TE sensor (outdoor heat exchanging temperature sensor)
• Attachment
With the sensor leads pointing in the direction shown in the
figure, install the sensor onto the straight pipe part of the
condenser output pipe.
TS sensor (Suction pipe temperature sensor)
• Attachment
With its leads pointing downward, point the sensor in the
direction of the packed valve, and install it onto the straight
pipe part of the suction pipe.
TD sensor (Discharge pipe temperature sensor)
• Attachment
With its leads pointed downward, install the sensor facing dowmward onto the vertical straight pipe
part of the discharge pipe.
TO sensor (Outside air temperature sensor)
• Attachment
Insert the outdoor air temperature sensor into the holder, and install the holder onto the heat exchanger.
TGa/TGb sensor (Gas side pipe temperature sensor)
• Attachment
With its leads pointing downward, point the sensor in the direction of the front cabinet, and install
the sensor onto the straight pipe part of gas side pipe. Match the sensor protective tube colors with
the pipe marking colors and install the sensors. TGa is yellow, and TGb is red.
CAUTION
During the installation work (and on its completion), take care not to damage the coverings
of the sensor leads on the edges of the metal plates or other parts. It is dangerous for these
coverings to be damaged since damage may cause electric shocks and/or a fire.
After replacing the parts, check whether the positions where the sensors were installed are the
proper positions as instructed. The product will not be controlled properly and trouble will result
if the sensors have not been installed in their proper positions.
Procedure
Remarks
• Shown in the above figure is the
model M14GAV-E.
• The sensor mounting positions in
the model M18GAV-E are all the
same with the sole exception of the
TE sensor. Refer to the figure
shown on the left.
