TUBING
Mount the self tapping saddle valve or code valve on either a cold
or a hot water pipe. A side or top mount is best to avoid clogging
from pipe sediment. Connect 1/4" O.D. tubing to the saddle valve.
Copper tubing requires a brass compression nut and brass sleeve.
Plastic tubing requires a brass insert inside the tubing, a plastic
sleeve on the outside with a brass compression nut.
NOTE: DO NOT USE PLASTIC TUBING ON HOT WATER OR IN
CONTACT WITH ANY HOT PLENUM SURFACE OR DUCT.
INSTALLATION OF THIS SADDLE VALVE MUST MEET OR
