INSTALLATION OF HUMBBSBP2017-A--
BYPASS HUMIDIFIER
Bryant’s HUMBBSBP2017-A-- bypass humidifier can be installed
on either the supply or return plenum of a forced air system. This
unit requires an external bypass duct between the supply- and
return-air ductwork.
It is recommended to install the humidifier where it can be easily
serviced. If this humidifier is installed with a central cooling
system the bypass duct must have a shutoff damper to close during
the cooling season. Always install humidifier downstream of an
electronic air cleaner.
