5 MAINTENANCE
Remove batteries if the irrigation controller
will not be used for a prolonged period. The
controller contains an internal filter, which has
to be removed and cleaned every few months.
If the filter is not cleaned on a regular basis - it
could create problems. The life span of the
battery is at least one year.
