Battery care and timer maintenance
• Make sure you use only new Alkaline batteries.
• Keep clear of dirt and debris which may block the ball valve and cause the set program to stop.
• Timer cannot be reassembled if taken apart. Disassembling will void any warranties.
• To prevent corrosion, always remove the batteries when the timer is not in use for long periods of time or when the battery is low.
• It is recommended that two new Alkaline batteries are installed if you are going away for an extended period of time to ensure a stable watering program.

TROUBLESHOOTING

• If batteries are running low, the valve will close automatically.
• Ensure that the Run Time is not set to OFF.
• Check that the Frequency selected is longer than the Run Time, e.g., do not set a 90 minutes Run Time and a 1-hour Frequency.
• Make sure the tap is turned on.
