3. Open one of the sprinkler heads manually to release pressure from the lines.

To disconnect electrical power:

1. Find the circuit breaker controlling your irrigation system.
2. Switch the breaker to the off position.
3. Verify power is disconnected using a non-contact voltage tester near the timer box.

Wait several minutes after turning off power to allow any stored energy in capacitors to dissipate. Never handle electrical components while standing in water or with wet hands.

Removing the Old Timer

With utilities safely shut off, proceed to remove the existing timer. This step requires careful attention to preserve wire integrity for reconnection.

1. Remove the lid from the valve box.
2. Locate the terminal block where wires connect to the old timer.
3. Take a detailed photo of the current wiring arrangement.
4. Loosen the terminal screws securing each wire.
5. Gently pull wires free from their terminals.
6. Remove mounting hardware holding the old timer in place.
7. Extract the entire old timer unit from the box.

Handle wires delicately to avoid nicking or cutting them. If any wire appears damaged, plan to replace that section during installation.

Preparing the Valve Box

Before installing the new sprinkler timer Orbit unit, ensure the valve box is clean and dry. Moisture inside the enclosure can cause short circuits or corrosion over time.

1. Inspect the interior walls of the valve box for cracks or damage.
