From the shut-off valve, route a supply pipe to the valveinstallation site. For UV protection, use dark graySchedule 80 PVC on the inlet (pressurized) side of thevalve and all PVC pipe installed above ground. UseClass 200 PVC on the underground sprinkler lines.2. Flush the supply line thoroughly to remove all traces ofdirt and debris.3. Prepare two 1" slip/male thread adapters with three to fivecomplete wraps of PTFE tape, evenly covering the threads.CAUTION: Use only PTFE tape on threaded valveconnections. Pipe dope will damage plastic threads.4. Install the threaded adapters into the valve and tightensecurely. Using PVC primer and cement, install the valve tothe PVC pipe as shown in Figure 1.5. Route a multi-wire, direct-burial sprinkler valve cablefrom the sprinkler timer to the valve location. If the cablerun 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 fromeach valve solenoid to the white cable wire. This wire isdesignated as the valve common wire. Connect theremaining wire from the solenoid to one of the color-coded cable wires. Ensure all wire connections aresecure and waterproof.CAUTION: Use Toro Waterproof Wire Connectors(Model # 53687) or grease caps on all wire spliceconnections to prevent corrosion, connection failureand short circuit.7. At the sprinkler timer, connect the white common wire tothe output terminal labeled “C” or “COM.” Connect eachcolor-coded valve wire to the numbered outputterminals in the order you wish the valves to operateduring the automatic watering cycle.8. Open the shut-off valve from the water source.

(See Uniform Plumbing Code, Sec. 1007 [b].) It is advisable touse a regulator with any automatic valve to assure long life as well asuniform and controllable operation.Figure 2WaterproofConnectorModel #53687Valve Common WireMulti-wire Cable from TimerJar Top Anti-siphon Valve Models 53763 & 53764Installation and Operating Instructions
