POSSIBLE
POINT
If any low spots are present in the vapor line or the unit is
mounted higher than the dispersion system, a condensate
trap must be mounted at the lowest point in the line. This will
act to remove any pooled condensate from the steam line
and prevent spitting in the duct.
ELECTRICAL
WARNING
Open all disconnect switches before installing the unit.
Failure to do so could result in personal injury or death from
electrical shock.
Ensure that adequate service is available to carry 125% of
the rated unit amperage. Field wiring of the main power
supply is connected directly to the main power contactor
located inside the right side electrical compartment. Please
refer to the wiring diagram appropriate for the model
Herrmersion you have. A separate grounding lug is provided
for the ground wire. This is also located inside the right side
electrical compartment. Install short circuit & over-current
protection in accordance with the National Electric Code,
State, and local electrical codes.

A wiring diagram is located inside the control cabinet. The
wiring between the control cabinet and the humidifier unit
must be 105 °C rated wire. Use copper conductors only.
Please refer to the Control section in this manual for
information regarding electrical connections to be made
directly to the control system.
NOTE: Only qualified electrical personnel should perform
installation and start-up procedures.
WARNING
Open all disconnect switches before installing the unit.
Failure to do so could result in personal injury or death from
electrical shock.
The following pages contain unit wiring diagrams. Please
identify the applicable wiring diagram primarily by the number
of heating elements present on your unit. Refer to the chart
above. Units designed for 30 lbs/hr of steam output will have
2 heating elements, units designed for 45 lbs/hr of steam
output will have 3 heating elements and units designed for
90 lbs/hr of steam output will have 6 heating elements. The
only other difference between these diagrams pertains to the
control transformer. Please identify the appropriate wiring
diagram for your unit on the following pages.
