Control Circuit Connections
WARNING!
Do not install any controls inside the Herrtronic 6000
cabinet. Installations of any extraneous devices inside
the electrical compartment may cause erratic behavior of
the circuitry and will VOID the warranty.
The 6000 units with built-in blowers require no external control
wiring since the humidistat is built-in.
SECTION IV OPERATING INSTRUCTIONS
Start-up Instructions
1.
Check that the humidifier is properly mounted and level.
2.
Check that the water fill and drain are properly connected.
3. Check that the correct voltage and amperage service are
supplied.
4. With power off, double check all electrical connections and
plumbing connections to ensure that they did not loosen
during shipment.
5. With the “on-off-drain” switch in the “off” position, and the
control humidistat at its lowest setting, turn on the main
disconnect. The contactor should remain deenergized
and the power light should remain “off”. Place the “on-off-
drain” switch in the “on” position and the power light should
illuminate.
6. Turn the control humidistat up to its highest setting. The
contactor should pull in.
7.
After approximately a 5 second delay, the fill valve energizes
and water begins to fill the cylinder to the preset amp level
or cylinder full condition, depending on the incoming water
supply. When starting up the unit, it is best to put an amp
clamp on the power leg that passes through the toroid
transformer. Ensure that the humidifier fills to “cylinder full”
(approximately 1.5” from the top of the cylinder), or that
the amperage reaches the data plate maximum and the fill
valve de-energizes.
NOTE:
If upon initial start-up of this humidifier the cylinder is
slow in heating and/or the service light continues to come
on, drain the cylinder to 1/4 full. Turn off power at break
-
er, obtain some Alka-Seltzer tablets and crumble 1/2 of
one tablet (Alka-Seltzer) into the grey fill tee. Change the
middle blue dial on the left side of the circuit board, R18,
from 90% to 87%. Then turn the breaker on and run the
unit. If you have had to use these this step on a 240V unit
(6000-2,4), it is advisable that you order a GT-176-1 re
-
placement cylinder rather than the standard replacement
cylinder in the future so this procedure will not need to
be repeated. Upon receipt of the GT-176-1 cylinder, adjust
the dial, R18, on the circuit board back to 90%.

8. All units are equipped with a drain tempering feature which
mixes cold fill water with the hot drain water to protect
drain piping. Depending on your fill water pressure, some
adjustment of the fill metering valve may be necessary to
ensure drain water of less than 140°F. (See Figure 5.) To
deactivate, remove diode from socket CRI8 from circuit
board. (See Figure 7.)
9. Reset control humidistat to its desired settings. Typical
control humidistat settings are 30-40%.
NOTE:
The capacity of the humidifier can be adjusted between
50% and 100% of the maximum level by adjusting the
capacity adjustment potentiometer (labeled R39) on the
main circuit board. All units are set from the factory to
produce 4 lbs/hr. If the psychrometric conditions permit,
the 6000—2 may be increased to 8 lbs/hr by adjusting
R39 from 50% to 100% capacity. Refer to Figure 7.
CAUTION!
Inadequate airflow may allow humidity to collect in areas
causing condensation.
