TUBING
Mount the self tapping saddle 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 EXCEED
LOCAL CODES AND ORDINANCES.
Select location on vertical surface of warm air plenum for mounting
