Slit 4 mm Fig. 10-3-13 Left-hand connection with piping 2. Bend the connecting pipes so that they are positioned within 43 mm above the wall surface. If the connecting pipes are positioned more than 43 mm above the wall surface, the indoor unit may be unstable. [. . . ] Refer to the figure shown on the left. 13 TD sensor (Discharge pipe temperature sensor) · Attachment With its leads pointed upward, install the sensor onto the vertical straight pipe part of the discharge pipe. 14 TO sensor (Outside air temperature sensor) · Attachment Insert the outdoor air temperature sensor into the holder, and install the holder onto the heat exchanger. Detail A TS sensor Detail B TD sensor Arrow D TO sensor TO sensor holder 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. CAUTION 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. ­ 113 ­ No. 15 Part name Replacement of temperature sensor for servicing only Common service parts of sensor TO, TS, TE, TD Procedure 1) Cut the sensor 100 mm longer than old one.
