HRJ 100 Installation Instructions

Installation #

1. Attach the Valves #

After flushing lines, install the valve to the manifold with an adapter or nipple. DO NOT OVERTIGHTEN. Do not use pipe dope. Use thread seal tape (Teflon tape) only. Note arrow for water flow direction. Valves have tapered fittings and therefore require seven to eight turns of thread seal tape to prevent leaking and to guard against the connections bottoming out. To prevent possible leaking, make sure that the manifold and pipe are properly aligned.

2. Attach Sprinkler Lines #

Attach sprinkler lines to the valve with an adapter.

RECOMMENDATION: Use the Hydro-Rain HRM Union Manifold fittings to make the valve easier to service or for future manifold modifications.

3. Run the Wire #

With the power turned off, connect the valves to the Hydro-Rain® controller (or any other controller that uses a UL-approved 24-volt Class 2 transformer as a power source). Use a multi-colored, multi-strand approved jacketed sprinkler wire. Be sure the wire has at least one more strand than the number of
valves in the manifold. Run the wire to the valves (usually in the same trench as the sprinkler pipe).

RECOMMENDATION: Use a piece of PVC pipe as a protective covering for sprinkler wire in areas of frequent digging.

RECOMMENDATION: Use a B-hyve Pro connected controller for enhanced control and monitoring of your system.

4. Attach the Wire #

Attach a colored wire to one valve wire on the solenoid and the white common wire to the other wire on the solenoid. It doesn’t matter which solenoid wire you use as the common. Attach the colored wires to the corresponding zone terminal in the timer and the common wire to the common connection in the timer. Use standard 20 gauge sprinkler wire for distances less than 800 feet (244 m). Use 18 gauge wire for distances over 800 feet (244 m). Use a Hydro-Rain Speed-Seal or grease cap and wire nut at each valve connection, and at any splices made along the sprinkler wire.

5. Close the Sprinkler Valves #

Turn the manual bleed lever clockwise until closed. When the water is turned on, the valve will remain closed.

6. Test the System #

After all pipes and fittings have been installed, turn the water supply on and check for leaks with the valves closed.

7. Open the Valves #

Turn the manual bleed lever/screw counterclockwise to manually open the valve. Then close the manual bleed lever/screw to shut the valve off.

The system is now ready to be controlled electrically from the controller or manually by opening the manual lever/screw.

  1. Always check local codes before installing any sprinkler system.
  2. Arrow indicates the direction of water flow.
  3. If static water pressure exceeds 80 psi (5.5 bars), a pressure regulator should be used.
