INSTALLATION & SER VICE INSTRUCTIONS 690 Series Rotary Sprinkler

Features

• Positive Spring Retraction - Pulls nozzle and cap down out of the way of people and turf maintenance equipment.

• Three Nozzle Sizes - Multiple nozzle sizes provide 45.1 to 82.2 GPM flow and produce watering radii from 78 to 108 feet.

• Long Life Gear Drive - Gear drive mechanism is vacuum-packed with lubricant and isolated from water stream for long, trouble-free life.

• Valve-In-Head Models - Permits head-by-head control to customize turf watering for various topography and soil conditions. Multi-cycle for wind or runoff problems, frost control and dew removal without low-head drainage. Available for hydraulic normally open or 24 Volt electric systems.

• Sprinkler Operating Mode - Electric valve-in-head models have three modes of operation; AUTO, ON and OFF. Mode is set using a selector tool inserted through the sprinkler body flange.

• Built-in Check Valve - Check-o-matic sprinklers utilize a check valve in the sprinkler base to prevent seepage from low area heads after valve closure. Check valve will hold up to 35 feet of elevation differential.

• Two-Speed / 60°-120° Models - Provides for more even precipitation. Runs at half speed in non-overlapping areas.

• Two-Speed / 180° Models - Provides for more even precipitation where only a selected area is covered by an overlap, such as is found on greens. Runs at half speed in non-overlapping areas.

• Serviceability - All internal parts of the sprinkler are accessible through the top of the sprinkler body .

Installation Procedure

To assure maximum performance from your 690 Series Rotary Sprinklers, read these instructions completely prior to installing or servicing the sprinkler.

Construct Swing Joints

1. Construct triple swing joints for each sprinkler as shown in Figure 1.Use PVC or ABS pipe nipple for sprinkler connection.

Note: On sites where the possibility of heavy equipment rolling over a sprinkler exists, the swing joint will flex preventing damage to the lateral or main lines. On a new installation in raw ground where the sprinklers are to be initially installed above the finished grade and lowered when new turf is established, the swing joint allows sprinkler repositioning without changing risers. This is a common and practical procedure which eliminates the problem of dirt being accidentally introduced into the lateral lines when a riser is changed.

2. Flush lines thoroughly prior to installing sprinkler.

3. Apply Teflon tape on riser threads. Install sprinkler to riser and tighten.

CAUTION Use only Teflon™ tape on riser threads. Use of pipe dope or other types of sealing compounds can cause deterioration of sprinkler body threads.

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 r uns 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-inhead 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.

Two-Speed Sprinkler Alignment - Models 696 and 698

There are two types of full circle sprinklers which have special arcs of slower then regular speed. Alignment of the heads is critical for proper performance. The model 696 sprinkler is a two-speed head with two 60° and two 120° arcs of speed. A red button on the drive assembly indicates it is a two-speed 60°–120° head and acts as a pointer toward the center of the fairway or the next head in the row of sprinklers. The model 698 sprinkler is a two-speed head with two 180° arcs of speed. A yellow button on the drive assembly indicates it is a two-speed 180° head and also indicates the center of the regular speed side. Align the sprinkler so the button points toward the center of the overlapped area of coverage. When a nozzle assembly is changed on either the 696 or 698 head, the main nozzle must be aligned with the small boss on the bull gear of the drive assembly.

Back Nozzle Alignment

When replacing the back nozzle, align it so the nozzles are vertical and the ramp is parallel to the ground. Use a 5/8 in. wrench to remove and align the back nozzle. See example at right.

Pilot Valve Operation

The main function of the pilot valve is to control the operation of the main valve located in the base of the sprinkler body. The main valve is operated by the release of water metered through the pilot valve when it is activated either manually or automatically by the 24 VAC coil assembly.

Another important function of the pilot valve is to regulate the water pressure to the sprinkler nozzle. Pressure regulation compensates for large variations within the system and maintains a constant pressure for optimum sprinkler operation. The 690 series pilot valve is factory set to regulate at 80 or 100 PSI depending on sprinkler model.

Sprinkler operation mode is set using a Toro Selector Tool (P/N 995-15) inserted through the body flange onto the pilot valve D shaped selector-cam. The "AUTO" mode permits automatic operation from the system controller. The "ON" mode opens the main valve for manual operation and "OFF" mode prevents the main valve from opening.

System Troubleshooting

Pilot Valve

Possible equipment failures with causes and corrective action are listed below.

PROBLEM POSSIBLE CAUSE – CORRECTIVE ACTION

1. Sprinkler will not turn on (a) No 24 VAC to coil assembly - Measure voltage with DVM. Check wiring and controller program - Refer to Controller Operating Instructions.

(b) Selector cam in "OFF" position - Set to "AUTO" position. (c) Debris in pilot valve assembly - Disassemble and remove all debris (See

Servicing Pilot Valve page 8.)

2. Sprinkler will not shut off (a) Constant 24 VAC from controller - Check for voltage using a DVM. If voltage is present, disconnect wire. If sprinkler closes, service controller. Refer to Controller Service Manual.

(b) Selector cam in manual "ON" position - Set to "AUTO" or "OFF" position. (c) Debris in pilot valve assembly - Disassemble and remove all debris (See

Servicing Pilot Valve page 8.)
