Installation precautions
CAUTION:
• The valve can be damaged if improper sweating (soldering) is used with the union
connection. Before sweating the union connection to the valve, remove the union nut
and O-ring from the valve body, then sweat the union tailpiece with union nut into place.
• Make sure that all connecting pipe work is water tight.
NOTICE:
• The valve body may be damaged if you overtighten when using PTFE pipe compound
or PTFE tape on pipe threads.
• Avoid damaging the valve operating mechanism by using too much joint compound.
Apply compound sparingly to male threads only.
Install NPT connection
1. Apply pipe compound conservatively to male connecting fittings only.
NOTICE:
Do not overtighten when using Teflon
® impregnated pipe compound and Teflon tape
on pipe threads. Doing so may damage the valve body.
2. Check connections for leaks.

CAUTION:
• Heat associated with the use of silver solder may damage valve components and void
the product warranty. Do not use silver solder.
