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.
