CAUTION: Use Toro Waterproof Wire Connectors (Model # 53687) or grease caps on all wire splice connections to prevent corrosion, connection failure and short circuit. 7. At the sprinkler timer, connect the white common wire to the output terminal labeled “C” or “COM.” Connect each color-coded valve wire to the numbered output terminals in the order you wish the valves to operate during the automatic watering cycle. 8. Open the shut-off valve from the water source. Test valve operation using the timer or manually at the valve. 6" (minimum) SCH 80 PVC Pipe From Water Source Slip x Male Thread PVC Adapters Manual Shut-Off Valve Use SCH 80 PVC Above Ground Class 200 PVC Underground Figure 1 Valve Installation Guidelines Ensure the following requirements, in addition to all local code requirements, are met when installing the Toro Jar Top Anti-Siphon Valve: • The installed height, measured from the valve base, must not be less than of 6" above the highest downstream outlet controlled by the valve. • The anti-siphon valve must not be subject to standing water which can rise to less than 6" from the base of the valve. • The anti-siphon valve must not be installed indoors (some spillage may occur) or in a valve box below ground level. • The installation site must be accessible to allow inspection and servicing. • Additional control valves must not be installed downstream of the antisiphon valve. • The anti-siphon valve must be installed vertically with the top of the anti-siphon cap level. • The valve must not be operated continuously for more than 12 hours in any 24-hour period. • Installing a manual shut-off valve between the main water supply and automatic valve or valve manifold is recommended for ease of valve maintenance and sprinkler system winterization. • Where local water pressure exceeds 70 psi, a pressure regulator should be used. (See Uniform Plumbing Code, Sec. 1007 [b].) It is advisable to use a regulator with any automatic valve to assure long life as well as uniform and controllable operation. Figure 2 Waterproof Connector Model #53687 Valve Common Wire Multi-wire Cable from Timer Jar Top Anti-siphon Valve Models 53763 & 53764 Installation and Operating Instructions Manual Operation Note: The valve can be manually operated using the external or internal bleed controls. Refer to Figure 3. Bleed Screw (external bleed): Turn the bleed screw counterclockwise one full turn or until water begins discharging past the bleed screw threads. Note: Removing the bleed screw is not required for manual operation, but can be removed to help flush debris from the upper diaphragm area. To close the valve, turn the bleed screw clockwise until it stops. Do not over-tighten! Bleed Handle (internal bleed): To open the valve, move the bleed handle coun terclockwise to the stop. The valve will open as discharge water is routed internally downstream. To close the valve, move the handle clockwise until resistance is felt. Do not over-tighten! Flow Control Adjustment The valve is set for maximum flow at the factory. If flow adjustment is required, use the following procedure: 1. While the valve is operating, use a small screwdriver to turn the flow control screw clockwise to decrease flow or counterclockwise to increase flow. Note: The flow control screw requires approximately seven turns to adjust from maximum to minimum flow. CAUTION: Do not use the flow control to shut off the valve. Do not force the flow control screw past the end of normal adjustment travel. Damage to the flow control components can occur. Figure 3 Bleed Screw Bleed Handle Flow Control Screw Maintenance Procedure The Toro Jar Top valve series features a threaded cap nut which enables the valve to be easily disassembled for maintenance. See Figure 4 for the following procedure. 1. Shut off the water supply and bleed pressure from the valve using the bleed screw. 2. Turn the cap nut (1) counterclockwise to remove. 3. Remove the cover assembly (2) by gripping the solenoid and gently rocking it back and forth until the assembly is loose and lifts off. 4. Remove the spring (3), diaphragm (4), and divider (5). 5....
