Useful Tips

• BATTERY LIFE
  – Only use fresh long-lasting alkaline batteries
  – Do not use rechargeable batteries
  – Turn off the unit when not in use
  – Remove the batteries before storage
  – Moisture sensor uses more energy
  – Frequently watering schedules can cause the batteries to drain faster
• CLEANING YOUR TIMER
  Your timer should be cleaned periodically. From time to time, you may get sediment or dirt build-up in your timer. Follow the information below.
  1) Turn off your water faucet. Remove the timer from the faucet connection and your hose connections. Look at the filter washer at the faucet connection input. Check that the filter washer is clear of any built-up sediment.
  2) If the filter is dirty, remove the filter washer from the timer. Clean out the filter washer by placing it under running water.
  3) Turn the timer upside down and activate the MANUAL mode. This will open up the valves and allow you to run water into the output connectors.
  By doing this, you can see if there are any clogs in the water flow. Once you see the water flow is correct, deactivate the MANUAL mode.
  
• SEASONAL STORAGE
  Cold or freezing temperatures can damage the timer if still connected to the faucet. At the first forecast of frost, it is best to remove the timer from the faucet and place the timer indoors. (Coldwater, if left in the timer, will damage the timer from the ice formed).
  – Remove the batteries when the timer is placed in storage
  – Recycle used batteries, do not dispose of in the garbage
