7. Maintenance, Troubleshooting and Repairs
• Batteries should be removed if the irrigation controller is not going to be used for a
lengthy period. The programs will disappear when removing batteries. Again reprogram
the controller.
• A filter must be installed upstream of the valve or system of valves and cleaned every
few months. Operation without a filter is liable to lead to malfunctions.
• Under normal usage, batteries (Alkaline) last at least a year.
• Do not run water through an irrigation line unless a solenoid is fitted on the hydraulic
valve.
• Recommended water pressure: 1-8 ATM (bar).
