review this checklist to ensure proper installation of the
product. Failure to follow the recommendations listed
below could result in failure or damage to the
humidifier or microprocessor.

the control cabinet door. Return all information to
the control cabinet after installation.
q Position the control cabinet so that it is in sight of
the humidifier tank.

from the control cabinet to the humidifier is 15
m or less.
q Connect an approved electric earth ground to the
earth ground lug in the control cabinet.

near the line voltage section of the control cabinet
or in the same conduit as line voltage wires.
q Never use shielded cable for water level probe
wiring.
q Attach the heater/machine ground lug in the
junction box, on the humidifier, to the subpanel
machine ground lug with the appropriate wire,
sized according to local regulations.
