INSTALLER: PLEASE FILL OUT AND MAIL GUARANTEE CARD AFTER INSTALLATION
IS COMPLETE. LEAVE INSTALLATION INSTRUCTIONS WITH HOME OWNER
PRECAUTION: The installer should be an experienced service technician. Disconnect electrical power before
beginning installation. Do not install where temperatures fall below 32 degrees F or where plenum temperatures
exceed 200 degrees F. When wiring into a multi-speed blower circuit see Step 7D.
INSTALLATION: The humidifier may be mounted with
the 6" outlet to the right or left by inverting the cabinet and
reversing the positions of the distributor trough and drain
pan. The humidifier may be mounted on the warm or
return air plenum with equal efficiency.
See Typical Installations.
ADDITIONAL MATERIALS THAT MAY BE NECESSARY:
1. 1/4" diameter plastic supply tubing or 1/4" copper
supply tubing for hot water applications
2. 6" diameter galvanized by-pass pipe
3. electrical wire and wire nuts
4. air pressure switch (G.F. Model #12500 suggested)

Select location on vertical surface of warm or return air plenum for
mounting humidifier. For plenum sizes 9 1/2" to 15" use 1040AD adapter
plate and five screws, 3 screws in top (supplied with DM model only).
Stick mounting template in place making 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, using connecting collar
as guide.

Cut out center section of template and 6" hole. Hang humidifier cabinet
and insert remaining four screws. Tighten all 8 screws. Install
connecting collar after drilling 1/8" holes for screws. Connect by-pass
pipe to collar and humidifier cabinet. Using holes at top and bottom of
humidifier bypass opening drill 2---1/8" holes through bypass pipe and
screw by-pass pipe to humidifier cabinet.

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.
