Installation Procedure

CAUTION: When assembling the Drip Zone Valve Kit components, use just 11⁄2 to 2 turns of Teflon tape on male threads. Never use pipe dope.

To achieve a leak-free thread connection, turn the male fitting until it is finger tight, then add one or two more turns. Over-tightening can cause splitting and failure of the female threads.

Important: Ensure the Y-Filter, Jar Top Valve and Pressure Regulator are installed in the correct flow orientation. Flow direction arrows are provided on each component. Refer to Figure 1 and Figure 2.

1.	Using the Close Nipple, install the Ball Valve to the Jar
	Top Valve inlet.
