1. The Model 570 may be installed on either the supply or return
plenum of a forced air handling system. Select a location for
the humidifier that allows for service and maintenance. Cut
out a rectangle 8-7/8” wide by 9 1/2“ tall. Extend horizontal
centerline of cut out to the adjacent plenum. Cut a 6” hole
10” to 15” from side of humidifier, on cabinet centerline, using
connecting collar as guide. The bypass is reversible and can
be mounted on the right or left side of the humidifier.
2. The humidifier is self retaining. Slide the top side in first,
then slide the chassis down. Level the chassis and install
center screws. If the by-pass pipe installs to opposite
side of chassis, bend clip on chassis, remove side panel,
and reinstall panel to opposite side of chassis. Install the
remaining four corner screws.
3. Connect the by-pass pipe to collar and humidifier cabinet.
Using holes at top and bottom of side panel discharge, pierce
two self tapping screws through by-pass pipe.
