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 the humidifier, which can
lead to duct nozzle water spitting or
leaking gasket. Remote hose must be
supported to prevent sagging or low
spots.

Choose a location for the humidifier and the
remote duct nozzle (see remote installs on
page 8).
It should have access for:
• Remote hose installation. Steam hose
must be installed with 2 in./ft. pitch on a
continuous uphill slope.
• Drain. Allow a continuous downslope to the
drain.
• Cold water line.
• Electrical circuit rated to your humidifier
(see circuit ratings on page 10).

When remote mounting
, also follow these critical
steps in sizing the proper humidifier:
The 6-gallon model can be remotely mounted up to
15 feet if insulating the steam distribution tube
The 9- and 12-gallon models can be remotely mount-
ed up to 20 feet.
Ensure at least 2 in. per foot slope if installing the
remote hose horizontally.
