Important: Read all of the instructions before installing the Pump Start Relay. Follow all local wiring codes and requirements. Have a
qualified electrician install the relay if there are any questions about the requirements for proper installation.
1. Selecting a Location
Turn off the power at the main circuit breaker panel, and attach an appropriate safety lockout device. The
pump may require at dedicated circuit. Do not have the pump and sprinkler controller on the same circuit.
Determine the desired location for the Pump Start Relay box. It should be mounted 5 feet away from the sprin-
kler controller. The sprinkler controller should be mounted at least 12 feet away from the pump. To help pre-
vent overheating the Pump Start Relay box should not be mounted in direct sunlight.
2. Attaching the bracket
Attach the mounting clips to the back of the relay box using the screws included. (See Illustration 1)
3. Connecting the Wires
Remove the relay box cover. Unscrew the four screws located on the corners of the box.
Determine the desired location for the incoming AC power wires, the location for the wires to the pump, and
the location for the wires to the timer.
Use a screwdriver and hammer to remove the desired conduit knockout plugs.
Attach the relay box to the wall using either the mounting template or the corner holes with the No. 8 screws.
Use expanding anchors in plaster or masonry. Up to six screws can be used for mounting the relay box. (See
Illustration 1)
Attach the appropriate conduit fittings to the box (Follow local code requirements).
Run the AC wires of AWG 12 with a temperature rating of 155º F/68º C into the relay box and connect them
to the appropriate relay wires. The wires are labeled "power in" from main power source, and "power out" to
pump (refer to diagram on housing unit). Use the wire nuts provided to make the connection. Make sure
there is no bare wire exposed. Connect the ground wires. (See Illustration 2)
Run the sprinkler controller wires of AWG 16-24 (155º F/68º C) into the box and connect them to the relay
wires labeled 24V. Use wire nuts to make the connections.
Re-inspect each connection to ensure the wires are properly connected.

4. Re-install the box cover
Tighten the screws until they are snug, but do not over tighten or the screws may break.
5. Connect the sprinkler controller
Connect the sprinkler controller wires to the controller by connecting one wire to the terminal labeled
"Pump" or "Master Valve". The other wire should be connected to the terminal label "Com" or "Common".
6. Test the System
Turn the power back on and test the system.

Warning! Always shut off the power supply before opening the relay box cover! Never open the relay box cover when it is raining! Do
not exceed the maximum recommended voltage or horsepower rating (2HP at 240V, or 1HP at 120V)! Do not exceed the coil maximum
recommended voltage of 30 VAC!
