1. Select location on vertical surface of warm or return air
plenum for mounting humidifier. Tape mounting template
in place making sure the template is level. Do not install
humidifier or 7" 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 7” circle 10” to 15” from side of humidifier, on cabinet

down. Level chassis and install two center screws. If bypass
pipe installs to opposite side of chassis, bend clip on side
discharge, remove side discharge, and reinstall discharge to
opposite side of chassis. Install remaining six screws. Insert
