Select location on vertical surface of warm air plenum for
mounting humidifier. Stick mounting template in place
making sure the template is level. Do not install humidifier
where the blanked off ends of a cooling coil will restrict air
flow to the humidifier.

Center punch the four side mounting holes on the template
and drill with an 1/8" drill bit. Cut out center section of
template. Remove the template and insert the four sheet
metal screws until the heads project about 1/8".

COPPER
TUBING

Install evaporator plates in pan. Insert the humidifier in the
plenum such that the four screws project through the keyhole
slots. Slide the humidifier down level and tighten four screws.

PLASTIC
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.
