Replacing the Battery

• The battery will maintain your program in case of an AC

• Battery should last approximately one year

• Open by sliding the battery tray out to the right

• Insert one CR2032 battery into the compartment with

• Slide back into place.

A weak or missing battery can cause the time, date, and

program to be erased after a power failure. If this happens,

you will need to install a fully charged battery and reprogram

Tip: Replace battery every year, to avoid loss of programming

Note:A battery alone will not operate the valves in your

sprinkling system. The sprinkler timer has a built-in transformer

that must be connected to an AC line voltage source.

Orbit sprinkler valves are designed for automated irrigation systems and are controlled by a computerized timer box. Manual operation is also possible when it is necessary to test the valves after repairs have been made or for sprinkler maintenance checks. Because the normal irrigation cycle may occur when you're not home, manual operation gives you the chance to make sure everything is working smoothly. The valves can be operated manually from the timer box or while standing at the valve.

From the Timer Box

Turn the dial to the 'Auto' position and press the 'Manual' key to test the valves on Easy Dial and Easy Set Orbit timers. Each valve will be activated in sequence for the duration it is set for. To test a single valve, use the arrow keys to navigate to the desired zone and press the '+/-' keys to set the duration of the test.
Turn the dial to the 'Auto' position and move the slide switch for the desired valve up to the 'Manual On' position to test valves on Orbit's 'Individual Station Slide' timers. To test all the valves in sequence, simply press the 'Manual' key and press 'Enter.'
Check to make sure the selected valves come on as they are activated manually. If a valve does not come on, check the wiring and the solenoid to find the problem.
Press 'Clear' to stop the manual watering cycle at any time, or slide the the switch to the 'Manual Off' position for the 'Individual Station Slide' models. If a valve does not shut off, debris inside of it is likely causing the problem. Unscrew the solenoid and the lid of the valve, remove the internal parts and rinse them off. Reassemble the valve and test it again.

From the Valve

Rotate the solenoid a half turn counterclockwise to activate the valve manually, if it is a model with a lever marked 'on/off' at the base of the solenoid. The solenoid is the cylindrical device on top of the valve. If the solenoid does not have an 'on/off' lever, rotate the bleed screw counterclockwise a half turn to activate the valve. This is a black plastic screw in the top of the valve below the solenoid.
Watch to see which irrigation zone comes on. If nothing happens and water cannot be heard running through the valve, there is a problem with the water supply. Find the master valve that supplies water to all the individual valves and turn it on.
Observe each sprinkler in the zone to see if it sprays in the right direction. To adjust the direction of spray, grasp the extended riser and rotate it to spray where needed. If the spray distance is incorrect, adjust it with the screw on top of the sprinkler head -- clockwise reduces the spray and counterclockwise increases the spray

Tip

For greater flexibility and convenience, use Orbit's remote control timer system. With the touch of a button, the valves can be activated from anywhere in the yard.
