Maintenance Features

• Filter Cleaning: Clean the filter regularly and replace it when worn to extend the timer's working life.
• Winter Storage: Remove batteries during winter months. Drain the timer and store it indoors to avoid freezing.
• Installation: Do not use tools to install the timer; tighten by hand only to prevent damage.
• Leak Prevention: Ensure the timer is firmly attached to the tap and hose, using a rubber washer and thread sealing tape if necessary, to prevent leakage.
• General Care: Do not subject the product to extreme force or shock.
• Battery Type: Use brand new alkaline batteries. Rechargeable and carbon batteries have a short and unstable battery life.
• Water Output: If Zone 1 and Zone 2 are switched on at the same time, the water output will be different.

Troubleshooting

• The water inlet leaks:
  • Possible reasons: No filter or filter not placed horizontally; tap not standard 3/4".
  • Possible solutions: Add a filter and ensure horizontal placement; ensure tap is 3/4"; reinforce with raw rubber wrap; use tape.
• The water won't stop/flow out:
  • Possible reasons: Valve blockage; low water pressure; incorrect installation.
  • Possible solutions: Check water pressure; check timer installation; wash the rubber filter.
• Short battery life:
  • Possible reasons: Mixed use of old and new batteries; use of carbon or rechargeable batteries.
  • Possible solutions: Use brand new alkaline batteries. Rechargeable and carbon batteries have short, unstable life; use alkaline batteries instead.
