Connecting Hydraulic Control Tubing (Hydraulic Models Only)

1.Route control tubing from the controller to the sprinkler location(s).

Note: Leave an 18" (45.7 cm) service loop of tubing at each sprinkler to facilitate movement of sprinkler and service operations. Refer to Table 2 for tubing run length and sprinkler elevation information.

2.Flush tubing thoroughly to remove all air and debris.

3.Remove the tube retainer and poly cap from the tubing adapter at the base of the sprinkler.

*• All hydraulic connections on Toro valves are 1⁄4" insert type.

•Control line pressure must be equal to or greater than mainline pressure.

•Control line pressure range is 40 to 150 PSI.

4.Slide the tube retainer over the end of the control tubing and attach tubing to adapter.

5.Slide tube retainer over the adapter area to secure tubing.

System Start Up _________________________________________________________________

WARNING

NEVER STAND OR LEAN OVER THE SPRINKLER WHILE THE IRRIGATION SYSTEM IS BEING FILLED, DURING MANUAL OR AUTOMATIC OPERATION OR WHEN PERFORMING SPRINKLER SERVICE PROCEDURES. DIRECT CONTACT WITH IRRIGATION SPRAY, A FAILED OR IMPROPERLY INSTALLED SPRINKLER CONNECTION OR SPRINKLER COMPONENTS FORCIBLY EJECTED UPWARD UNDER PRESSURE CAN CAUSE SERIUS INJURY.

The following is a recommended procedure that will protect system components during system start-up. The procedure is based on a velocity fill rate of less than 2' (0.61 m) per second. See Table 3 below.

1. Use jockey pump only to fill the system at a velocity fill rate of less than 2' (0.61 m) per second.

CAUTION: Failure to comply with recommended fill rate will increase line pressure resulting in a water hammer effect that could damage sprinklers and piping components.

2.Use quick coupler keys at all tees and greens with quick coupler valves to bleed air from the system lines during the filling process. For best results, do not compress air and then relieve it – bleed the air continuously while filling the system.

3.After water has filled all lines and all air is removed, remove the quick coupler keys.
