Connecting Electric Control Wires Table 1 - Wire Sizing Chart

1.Route control wires to sprinkler location(s). Provide enough extra wire at sprinkler to allow for movement of sprinkler without straining wire connections. One common wire and one station

wire are required for each sprinkler. See Wire Sizing Chart, Table 1 for proper application.

2.Attach control wires to solenoid leads using an approved waterproof splicing method.

CAUTION

All wires must be waterproofed to prevent short circuit to ground and subsequent controller damage.

Connecting Hydraulic Control Tubing

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

Note: Leave an 18 inch service loop of tubing at each sprinkler to facilitate movement of sprinkler and service operations. Tubing runs in excess of 1,000 feet are not advisable due to delayed response time. The controller for hydraulic valve-in-head systems should never be located more than 25 feet below or more than 70 feet higher than the valves. Although there is no limit to the amount of hydraulic valve-in- head sprinklers controlled by one control station, practical experience suggests the maximum number of heads normally used is five.

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

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

4.Slide tube retainer over control tubing and attach tubing to adapter. Slide tube retainer over adapter area to secure tubing.

System Start-Up

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 feet per second. See Table 2 below.

1. Use jockey pump only to fill system at velocity fill rate of less than 2 feet per second.

WARNING

TO PREVENT PERSONAL INJURY, DO NOT STAND DIRECTLY OVER ANY COMMERCIAL OR LARGE TURF HEAD DURING FILL OR WHEN ACTIVATING MANUALLY AT THE HEAD.

2.Use quick coupler keys at all tees and greens with quick coupler valves to bleed air from system lines during filling process. Do not compress air and then relieve - bleed air while filling system.

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

CAUTION

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