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 anti- siphon 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.

Installation Procedure

1.From the shut-off valve, route a supply pipe to the valve installation site. For UV protection, use dark gray Schedule 80 PVC on the inlet (pressurized) side of the valve and all PVC pipe installed above ground. Use Class 200 PVC on the underground sprinkler lines.

2.Flush the supply line thoroughly to remove all traces of dirt and debris.

3.Prepare two 1" slip/male thread adapters with three to five complete wraps of PTFE tape, evenly covering the threads.

CAUTION: Use only PTFE tape on threaded valve connections. Pipe dope will damage plastic threads.

4.Install the threaded adapters into the valve and tighten securely. Using PVC primer and cement, install the valve to the PVC pipe as shown in Figure 1.

5.Route a multi-wire, direct-burial sprinkler valve cable from the sprinkler timer to the valve location. If the cable run is less than 800', 18-gauge wire is sufficient. For dis- tances from 800'–2000', 14-gauge wire is recommended.

6.Using wire splice connectors, attach either wire from each valve solenoid to the white cable wire. This wire is designated as the valve common wire. Connect the remaining wire from the solenoid to one of the color- coded cable wires. Ensure all wire connections are

secure and waterproof.

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.
