Please conduct the overall periodic inspections preferably semiannually or at least annually in con-
junction with the below operation check.
Periodic inspections item
• Please carry out the periodic inspections and cleaning because mechanical error can occur when
the sensors or pit are clogged up by trash, foreign materials and mosses. Also, when cleaning the
sensor, wipe out using a soft cloth dipped in water.
• When trash, sand and snow are accumulated on the float sensor, please remove them at times
because the water line comes down and the sensitivity changes.
• Please check that there is no cable breakage or wiring trouble (loosening of the screw), then carry
out the operation check.
