Connecting Electric Control Wires

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.

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.
