DEDICATED MONITORING

INSTALLATION OPTIONS FOR THE MODEL 300

Model 65

Dedicated monitoring

and control of the

humidier from the

living space.

Disclaimer:

• Using multiple discharge registers may lead to unequal humidity levels.

Air ow favors the path of least resistance, so shorter, straighter duct runs will receive more

humidied air than runs that are longer and have more bends or transitions. Over time,

humidity will equalize throughout the living space.

• Discharge registers should be placed on an interior wall.

The unit can be mounted off the joists or in between joists which

are spaced at least 14.5” apart. Hard duct or ex duct can be used.

The sound of the unit decreases when using ex duct.
