Setup and Installation
Follow these steps to properly set up your RAINPOINT 3 Zone Water Timer:
- Battery Installation: The timer requires 4 AA alkaline batteries (not included). Open the battery compartment on the back of the unit, insert the batteries according to the polarity markings, and securely close the compartment. The compartment is designed with a silicone seal for waterproofing.
- Check Water Inlet Filter: Ensure the water inlet filter is clean and properly seated to prevent impurities from entering and blocking the valve.
- Install on Faucet: Wrap Teflon tape (included) around the threads of your outdoor faucet. Attach the timer to the faucet, ensuring it is hand-tight only to prevent leaks. Position the timer vertically so the water outlets face downwards to prevent rainwater infiltration. If faucet threads cannot be tightened, add a rubber washer to avoid leakage.
- Connect Hoses: Attach your garden hoses or drip irrigation pipes to the three brass outlets at the bottom of the timer. Ensure these connections are also hand-tight and secure.

Maintenance
- Clean Water Inlet Filter: Regularly check and clean the mesh filter inside the water inlet to prevent debris from clogging the timer and affecting water flow.

- Winter Storage: During freezing temperatures, remove the timer from the faucet and store it indoors to prevent damage.
Troubleshooting
- No Water Flow: Check if the faucet is fully open, the water inlet filter is clean, and the batteries are charged. Ensure a watering program is active or manual watering is initiated correctly.
- Leakage: Ensure all connections (faucet to timer, timer to hoses) are tight and properly sealed with rubber washers and Teflon tape. Check for cracks or damage to the unit or hoses.
- Timer Not Responding: Replace batteries if the low battery indicator is on or if the display is dim. If issues persist, try resetting the timer by removing batteries for a few minutes and reinserting them.
