Resumen del manual
Where local water pressure exceeds 70 psi, a presure 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. Valve Specifications: Operating Pressure: 20–150 PSI Flow Range: 0.25–30 GPM Solenoid: 24 V a.c., 60 Hz (nominal) 19 V a.c., 60 Hz (minimum) Inrush: 0.40 amps, 9.6 VA @ 24 V a.c., 60 Hz Holding: 0.20 amps, 4.8 VA @ 24 V a.c., 60 Hz Friction Loss: GPM Flow 0.25 5 10 15 20 30 PSI Loss 2.0 3.5 4.0 3.0 3.3 6.2 Installation Procedure Note: To ensure ease of installation and optimum valve performance, please read through the following instructions completely before starting the installation procedure. Step 1- Route 1" schedule 40 PVC pipe from the backflow preventer or system shut-off device to the valve location. Flush the supply line thoroughly! Caution: Dirt, rocks and debris entering the valve can damage the valve and/or cause the valve to malfunction. Step 2- The instructions and illustrations on the next page provide the most commonly recommended methods of installing in-line valves in a manifold arrangement. Use the appropriate step-by-step instruction for the valve model being installed.

B 1" In-line Valve Models 53707 and 53709 53707 53709 • Model 53707 Installation (Figure 1) Step 1- Cut a 4" length of 1" schedule 40 PVC pipe for each valve. Step 2-Using PVC primer and cement, assemble the pipe section to the valve inlet and tee fitting, aligning the tee perpendicular to the valve. Repeat this procedure for each valve in the manifold. Note: The last valve in the manifold can be connected with a 90° elbow instead of a tee. However, if future expansion of the sprinkler system is expected, use the tee fitting and a 4" section of 1" schedule 40 PVC pipe capped on the end. This enables the main line to be easily connected to additional downstream valves. Step 3- Using 4" sections of 1" schedule 40 PVC pipe, connect the valve assemblies together to create the manifold, making sure the valves are aligned during assembly. Step 4- Ensure the end of the supply line is dry and free of burrs. Cement the manifold to the main line. Step 5- Allow the cemented connections to cure for a minimum of one hour (or per the cement manufacturer’s directions) before applying water pressure. If no leaks occur after pressurization, begin connecting the sprinkler zone piping using 1" class 200 PVC pipe. • Model 53709 Installation (Figure 2) Step 1- Apply three complete wraps of PTFE tape to the slip/thread adapters. Caution: Use only PTFE tape on threaded connections. Pipe dope and other types of pipe thread sealants can damage plastic threads. Step 2- Install a slip/thread adapter into each end of the valve and tighten securely. Step 3- Cut a 4" length of 1" schedule 40 PVC pipe for each valve. Step 4- Using PVC primer and cement, assemble the valve and PVC components as shown, aligning the tee fitting perpendicular to the valve. Repeat this procedure for each valve in the manifold. Note: The last valve in the manifold can be connected with a 90° elbow instead of a tee. However, if future expansion of the sprinkler system is expected, use the tee fitting and a 4" section of 1" schedule 40 PVC pipe capped on the end. This enables the main line to be easily connected to additional downstream valves.

Step 7- Allow the cemented connections to cure for a minimum of one hour (or per the cement manufacturer’s directions) before applying water pressure.
