Followtheseinstallationinstructionscarefullyfortrouble-freeoperation.
Mostoperationproblemsarecausedbyimproperhoseinstallation.Alwaysensureanuphillflow
when installing the remote hose, and avoid kinks, sharp turns, or low spots that could restrict
the flow of steam into the injection nozzle or condensation back into the humidifier.
If the remote hose cannot be installed with an upward pitch of 2 in./ft., a wetted drip tee must
be installed. Failure to do so can result in back pressure on TrueSTEAM, which can lead to duct
nozzle water spitting or leaking gasket. Remote hose must be supported to prevent sagging or
low spots.
