Installation Instructions
Place the water diaphragm spring in the center of the stainless steel cup located on the underside of the PVK-1 top. The magnet in the top will hold the spring upright. Install the metal orifice plate on top of the spring and verify that the spring remains vertical.
Next, place the rubber diaphragm into the valve base and ensure it is properly seated in the opening. The pneumatic top is now ready to be installed onto the valve base. The pneumatic top may be oriented in any direction.
Align the mounting holes, then insert the screw with the lock washer and secure it with the nut. Tighten all hardware securely.
The valve base includes a directional arrow indicating water flow. Ensure the arrow points toward the tee or elbow supplying water to the bubbler or showerhead.
