6 . Maintenance
•
Batteries should be removed if the irrigation controller will not be
operated for a prolonged period.
•
A filter must be installed upstream to the solenoid valve. Clean the
filter once every few months. A clogged filter can be the source of
system malfunctions.
•
Under normal usage, batteries (Alkaline) will last for at least one year.
•
Do not run water through a line unless the solenoid is fitted on the
hydraulic valve.
•
Recommended water pressure range: 1-8 ATM (bar).
