• 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 mani- fold 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.

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 5- 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 6- Ensure the end of the supply line is dry and free of burrs. Cement the manifold to the main line.

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. If no leaks occur after pressurization, begin connecting the sprinkler zone piping using 1" class 200 PVC pipe.
