Select location on vertical surface of warm or return air plenum for
mounting humidifier and tape mounting template. Make sure the
template is level. Do not install humidifier or 6" bypass pipe where the
blanked off ends of a cooling coil will restrict air flow to the humidifier.
Extend horizontal centerline from template to the adjacent plenum.
Scribe 6” circle 10” to 15” from side of humidifier, on cabinet centerline.

Start the three initial mounting screws. Mount humidifier cabinet in
level position and tighten screws. Install six additional screws at top
and sides of cabinet.

Cut 6” hole and install connecting collar, 6” elbow and by-pass pipe
(not supplied). USE UNCRIMPED END IN HUMIDIFIER CABINET.
Connect by-pass pipe to collar and humidifier cabinet. Using holes
at top and bottom of humidifier bypass opening, screw by-pass pipe
to humidifier cabinet. Install bypass cover by placing the tab of the
bypass cover marked "TOP" behind the top flange of the humidifier
cabinet, push up on the bottom clip until it clears the opening of the
humidifier cabinet then push in on the bottom of the bypass cover.

NOTE: If furnace is used for summer cooling, install inline
damper in by-pass pipe.

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.
