Introduction
The Orbit 58910 2-Outlet Programmable Digital Hose Watering Timer is designed to automate your watering schedule, providing efficient and convenient irrigation for your lawn and garden. This device connects directly to your outdoor hose faucet and allows you to set precise watering times, durations, and frequencies for two independent outlets. Its user-friendly interface and durable construction ensure reliable performance and water conservation.
Setup
1. Battery Installation
The timer requires two (2) AA alkaline batteries (not included). To install, locate the battery compartment on the back of the timer. Slide the battery cover off, insert the batteries according to the polarity indicators (+/-), and then replace the cover securely. The timer retains its program settings even when batteries are changed.
2. Connecting the Timer to Faucet
Before connecting, ensure the faucet is clean and free of debris. Thread the timer's swivel coupling onto your outdoor hose faucet. Hand-tighten until snug. Do not overtighten. The swivel coupling allows for easy and secure attachment without the need for tools.

The swivel coupling provides a quick and secure connection to your hose or faucet, and includes a mesh filter to prevent debris from entering the timer.
3. Connecting Hoses
Attach your garden hoses to the two independent outlets at the bottom of the timer. Hand-tighten each hose connection. Ensure all connections are secure to prevent leaks. Once connected, slowly turn on your faucet to full pressure.

Maintenance
Battery Replacement
When the battery indicator on the display shows low power, replace the batteries promptly to ensure continuous operation. Follow the battery installation steps outlined in the Setup section. The timer's program will be retained during battery replacement.
Cleaning the Filter
Periodically check the mesh filter located in the swivel coupling that connects to your faucet. If debris accumulates, remove the timer from the faucet, carefully remove the filter, rinse it under running water, and reinsert it. This helps maintain proper water flow and prevents clogging.
Winterization
Before the first frost, disconnect the timer from the faucet and hoses. Remove the batteries. Store the timer indoors in a dry, protected area where temperatures will not drop below freezing. Freezing water inside the timer can cause damage.
