Setup Instructions
- Prepare the Faucet: Ensure your outdoor faucet (spigot) is clean and free of debris.
- Attach to Faucet: Screw the timer's female coupling onto your outdoor faucet. Hand-tighten firmly to prevent leaks. Do not overtighten.
- Attach Hose: Screw your garden hose onto the male coupling at the bottom of the timer. It is recommended to attach the hose to the timer first, then attach the timer to the faucet, to avoid damaging the plastic threads on the timer. Hand-tighten firmly.
- Check for Leaks: Turn on the faucet slowly and check all connections for leaks. If leaks occur, tighten slightly more.

Operating Instructions
- Set Watering Duration: Rotate the dial clockwise to your desired watering time, ranging from 1 to 120 minutes. The timer will begin immediately.
- Automatic Shut-off: The timer will automatically shut off the water flow once the set duration has elapsed.
- Continuous Flow (Manual ON): To allow continuous water flow without a timer, rotate the dial counter-clockwise to the "Manual ON" position. The timer mechanism may still tick for a few minutes in this mode.
- Adjusting Set Time: Once a watering time is set by turning the dial clockwise, you cannot shorten the duration by turning the dial counter-clockwise to a lesser time. The timer will complete the longest duration it was set to. To reset, you must let the current cycle complete or turn the faucet off.

Maintenance
- Cleaning: Periodically inspect the timer for dirt or mineral buildup, especially around the connections. Clean with a soft brush and water if necessary.
- Winter Storage: During freezing temperatures, disconnect the timer from the faucet and hose. Drain any remaining water and store the timer indoors to prevent damage from freezing.
- Gasket Inspection: Check the rubber gaskets inside the couplings for wear or damage. Replace if necessary to ensure a watertight seal.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Water does not shut off. | High or low water pressure; internal mechanism issue. | Ensure water pressure is within typical household range. If pressure is too high, consider installing a pressure reducer. If the issue persists, contact support. |
| Water leaks from connections. | Loose connections; worn or missing gaskets. | Hand-tighten connections firmly. Check and replace rubber gaskets if they are damaged or missing. |
| Water leaks from timer body. | Defective unit; internal damage. | Discontinue use and contact customer support for assistance. |
| Timer does not start. | Dial not set correctly; insufficient water flow. | Ensure the dial is turned past the '0' mark to a specific time setting. Verify the faucet is fully open. |
| Incompatible with UK hose fittings. | This timer uses US GHT (Garden Hose Thread) which is different from UK BSP (British Standard Pipe) thread. | A thread converter is required for compatibility with UK hose systems. |
