SECTION IX
MAINTENANCE AND SPARE PARTS
Maintenance
The HydroRanger I requires no maintenance, however a program of periodic checks
would be beneficial.
The enclosure and circuit boards should be cleaned if necessary, but only when the
power is disconnected at the main breaker and using a vacuum cleaner and a clean,
dry paint brush. Check all electrical contacts in the HydroRanger I enclosure as well as
those in junction boxes, for corrosion and arcing.
If the HydroRanger I is mounted in dusty or oily environment, make sure that the
programmer and front cover is kept clean, otherwise it may impede the infrared signal
transmission required for programming.
It is also a good idea to periodically check the face of the transducer. It should be free
of material build-up corrosion or deformation.
