SECTION II UNIT OPERATION
Water Level
Output
Basic Operation
Installation, Operation, & Maintenance Manual
Controlled humidication requires a very precise control
system. The 6000 utilizes a solid state control to monitor
performance and maintain humidity. The humidier evaluates
the operation and alerts the operator to problem conditions
and prevents undesirable operation.
On initial start-up or a call for humidity, the humidier will
attempt to ll to its full load amp rating. The unit will not
necessarily have a full cylinder of water. Water level depends
on the conductivity of the water. The more conductive the
water, the more current that can be passed through the same
volume of water.
If the water is not conductive enough to allow the unit
to reach full load amps (full capacity) on the initial ll, the
cylinder full light will indicate a full cylinder condition. The
unit will operate in this mode with repetitive ll and boil cycles
until the unit has concentrated enough minerals in the water
to reach the rated amp level.
Once full load amp (FLA) has been reached, the ll valve will
shut off. The unit will now compare the rate of change of amp
draw to a time cycle.
If the water in the cylinder is mineral laden and hence very
conductive, a drain cycle will be initiated.
After the drain cycle and/or the time cycle is completed, the
unit will rell and start the process over.
These cycles will repeat until:
•The call for humidity is satised.
•The cylinder is used up.
•A fault condition occurs.
On initial start-up, if the water is not conductive enough for
the unit to reach FLA, the water will stop lling when the
water reaches the cylinder full electrode. Once the unit has
entered a cylinder full condition it will operate with ll and
boil cycles only. By eliminating the drain cycle, the water
conductivity will be increased by producing pure steam and
leaving the minerals behind. The increased mineral levels
will raise the conductivity allowing the humidier to draw
sufcient amperage to achieve FLA. Normal operation will
then commence.
As the electrodes in the cylinder are coated with minerals,
the water level will slowly increase to the cylinder full level.
Concentration of coating on electrodes will no longer allow
the unit to reach FLA. After a period of time, the unit will
display the red “Service” light indicating the need to change
the cylinder.

Installation, Operation, & Maintenance Manual
Plumbing
To make the necessary connections for water ll and drain, the
following steps are required: (refer to Figure 3 for locations)
1. Install external shutoff valve between the water supply and
the humidier for ease in servicing the unit.
2. Connect water supply to the 1/4’ compression tting on the
bottom of the cabinet.
CAUTION!
Do not use reverse osmosis or demineralized water
treatment without rst consulting the factory. This
water may not be sufciently conductive to allow proper
operation. Consult factory if water is outside the range of
allowable conductivities. Do not use hot water.
3. Connect the 3/4” tube from the accessory pack to the drain
reservoir. Cut the tube to the length necessary to reach the
drain.
4. Insert the other end of the tube into a minimum 6” vertical
length of the 1-1/4” minimum I.D. drain line. The balance of
the drain line should be 1” I.D. minimum with a minimum
1/8” per foot slope. (See Figure 3.)
WARNING!
If the drain line is exposed, it is recommended that it be
insulated for safety. Do not use PVC drain line unless
“Drain Tempering” is enabled.
NOTE:
Inlet water pressure must be in the range of 20-100
psig. Consult the factory if you are outside this range.
Softened water may be used but requires that the low
drain threshold be adjusted. Drain water can be tempered
to lower its temperature.
Steam Distribution
The 6000 Series Steam Humidier with the built-in blower pack
should be mounted a minimum of 18” from the ceiling. There
should also be 5 feet of horizontal clearance in front of the unit
to prevent steam from condensing on obstructions (See Figure
1). There is an adjustable louver to adjust the direction of the
steam plume.
WARNING!
Do not adjust this louver to extreme angles as it will
restrict the airow causing condensation to form around
the steam distribution manifold.
WARNING!
Locate away from areas where people can walk into the
steam path.
Wiring
All eld wiring should be routed up through the knockout in the
bottom panel or in the back of the unit.

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 humidier is properly mounted and level.
2. Check that the water ll 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-offdrain” 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 ll valve energizes
and water begins to ll 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 humidier lls to “cylinder full”
(approximately 1.5” from the top of the cylinder), or that
the amperage reaches the data plate maximum and the ll
valve de-energizes.
8. All units are equipped with a drain tempering feature which
mixes cold ll water with the hot drain water to protect
drain piping. Depending on your ll water pressure, some
adjustment of the ll 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 humidier 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 airow may allow humidity to collect in areas
causing condensation.

NOTE:
If upon initial start-up of this humidier 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 breaker, obtain some Alka-Seltzer tablets and crumble 1/2 of
one tablet (Alka-Seltzer) into the grey ll 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 replacement 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%.

Installation, Operation, & Maintenance Manual
Maintenance
To maintain output, the water level in the cylinder will slowly
move upwards, exposing new electrode to the water as the
electrodes become coated with minerals. Eventually, all of the
usable electrode surfaces will be coated and the cylinder will be
full of water. At this point, the output will begin to drop and the red
“service” light will come on. The unit will shutdown. This indicates
the need to change the cylinder, typically 500-2000 hours of
operation, depending on the quality of the ll water supply.
To replace the cylinder
1. Drain cylinder completely using the ‘on-off- drain” switch.
2. Turn off power to the unit at the external disconnect.
Disconnect electrode power wires (#38 & #39) and
cylinder full electrode wire (#29) from the cylinder. These
connections are 1/4” quick connects. (See Figure 6B, 6C,
& 6D.)
3. Disconnect 1” hose at top of cylinder.
4. Remove cylinder, clean out the drain cup and insert the new
cylinder. Be sure that “o” ring is in place on the cylinder ll/
drain port prior to installation. (See Figure 6A.) New o-ring
is included with each replacement cylinder.
5. Clean and check both the ll and drain valves while servicing
the unit.
6. Check the strainer. If it is dirty or restricting the waterreplace it.
7. Install cylinder in unit by pushing downward with a slight
twisting motion, while ensuring proper orientation of cylinder
within cabinet.
8. Reconnect electrode power wires (#38 & #39) and cylinder
full electrode, wire (#29). Make sure that all electrical
connections are securely tightened. (See Figures 6B, 6C,
& 6D.)
9. Follow cold start-up instructions on page 8. Monitor amp
draw for several cycles. .
Extended Shutdown
Always drain cylinder completely if unit will be off for an extended
period of time. This will preserve the life of the cylinder.

SECTION V TROUBLESHOOTING GUIDE
All Herrtronic 6000 Series Humidiers are manufactured under
strict quality control and are subjected to a complete operational
test before shipment. All circuit board adjustments are made at
the factory and should not be adjusted beyond the guidelines
set in this troubleshooting guide without rst consulting a factory
representative. The following information is for your help and
reference. If you still experience difculty after trying these
remedies, contact your TRION/HERRMIDIFIER representative.
WARNING!
The Herrtronic 6000 Series Electronic Steam Humidier
cabinet was designed to house and shield the
components from outside interference. Absolutely
NO other components may be mounted inside or be
electrically tapped into the humidier without TRION/
HERRMIDIFIER’s express written permission. Failure to
heed this warning will void your warranty.
TEST POINTS
Each circuit board (See Figure 7) features three test points to
aid in the troubleshooting process. Each of these test points
works on a 0-4 VDC scale. “0 VDC” = 0%. “4 VDC” = 100%.
All readings are between the test point and ground (Molex J1,
terminal 11 [far right of molex connector, wire #11).
Test Point #1:
Provides exact reading of drain threshold setting.
Test Point #2:
Provides circuit board reference voltage. Should always
read 4 VDC +/-2%.
Test Point #3:
Provides actual percentage of output. For example, a unit
running at 80% of maximum output would have a Test Point #3
to ground reading of 3.2 VDC.
Maximum Capacity Setpoint
The potentiometer labeled “R39” located in the top left-hand
corner of the board allows adjustment of the unit’s capacity in
the range of 50-100% of maximum.

Unit Detected Faults: (Red Service Light is ON)
Problem / Symptom Probable Cause Reason - Correction
Overcurrent
The alarm condition occurs when an
overcurrent situation (>138% of rated
current) has occurred and the humidier
has shut down to prevent any damage.
This alarm indicates that there has been
a signicant reduction in resistance between the main legs of the supply power
and the humidier has been shut down to
prevent damage and should be serviced
before it is restarted. Overcurrent LED
CR 17 (Figure 7) is illuminated.
End of Cylinder
This alarm condition occurs if the humidi-
er is unable to reach full output over a 6
hour timeframe. It is constantly switching
between “ll” and “cylinder full” modes.
This alarm indicates a need to change
the cylinder, that the water supply is low
in conductivity, or that a foaming condition exists:
Fill System Fault
This alarm condition occurs when the ll
valve has been energized for a 6 hour
timeframe. The humidier has been
shutdown to prevent any damage.
Dead short between electrodes. Replace the steam cylinder. Check re-
sistance between electrodes with power
“off”
Restricted or blocked drain. Clean and inspect drain system.
Restricted ll system Clean and inspect the ll system. Check
for restriction or loss of supply pressure.
Incoming water conductivity is outside
the range of normal circuit board settings.
Check amp draw to unit during start-up.
If amp draw greatly exceeds rated amp
draw, the drain threshold pot, labeled
“% adj.” (R18), must be increased 2% to
increase the frequency and duration of
drains to reduce the conductivity inside
the cylinder.
End of cylinder life – Cylinder life is
typically between 500 and 2000 hours,
depending on incoming water supply.
If incoming water supply is less than 100
micromho, the unit may not be able to
pass the rated current through the water.
Foaming condition exists. Flush and ll the steam cylinder several
Loss of or restricted water supply Check ll system.
Leaking drain system. Check drain system.
Defective drain valve. Repair and replace as required.
Defective ll valve. Repair and replace as required.
Consult the factory for options.
Manually drain the unit and restart.
For emergency use, you may restart the
humidier with the capacity setpoint,
R39, at a lower level to allow operation
until a replacement steam cylinder can
be obtained. To clear the fault, turn the
main disconnect to the unit “off” and then
back “on”.
See – NON-FAULT ACTIVATED PROB-
LEMS GUIDE – “Unit lls to the cylinder
full condition and remains cold”
times and restart. If it persists, you must
lter or treat the water to remove the
foaming agent. See circuit board settings
on previous page if supply water is softened. See NON – FAULT ACTIVATED
PROBLEMS GUIDE – “Water foaming
inside the cylinder”
NOTE: The three fault conditions outlined above will cause the humidier to shut down and the service light on the front
of the unit to illuminate. To clear these faults, the main power must be turned “off” and back “on” again.

operate. Power lamp is “off”.
Unit turned “on”. Contactor pulled
in, but no water is entering the
cylinder.
Excessive arcing in cylinder Check drain valve and ensure that when it activates it drains freely. Clean if necessary.
Unit lls to the cylinder full condition and remains cold.
Unit turned on and cycles for a
short period of time. Then it stops
in the middle of a ll cycle and
won’t reset until boiling stops.
Check the wiring at the 24 VAC breaker for a short or loose connection.
Disconnect the contactor coil from the circuit and repeat. If 24 volt breaker doesn’t blow,
replace the contactor.
Replace the main circuit board.
Disconnect ll valve from electrical circuit. If circuit breaker doesn’t trip, replace the ll
valve.
Replace the main circuit board
Disconnect drain valve from electrical circuit. If circuit breaker doesn’t trip, replace the drain
valve.
Remove the drain valve and ensure that it is clean and free of any obstructing mineral
deposits.
Replace the main circuit board.
Check power supply.
Check circuit breaker.
Check connector J1 on the circuit board and ensure that it is plugged into the circuit board
properly and that no wires are loose.
Ensure that there is 24 VAC between pole #9 and #11 connector J1. If not, check wiring.
Check door interlock.
Check external shutoff valves and open if closed.
Check strainer and ll valve for clogs. Turn adjusting screw (Figure 5, page 8).
Check ll valve coil to determine if it is receiving 24 VAC. If so, replace the valve.
Check for break in wiring.
Replace valve if defective.
Check water supply. If it is softened, increase the drain threshold pot, “% adj.” (R18), up to
92% at 3.68VDC. (See Figure 7, page 11.)
Use high conductivity settings if water supply is very hard, >750 micromho.
Unit lling slower or at the same rate as the water is boiling, causing over concentration and
foaming. Check restriction in ll line. Adjust the metering ll valve to allow greater ow of
water. (See Figure 5.)
Have water analyzed. If iron content is greater than .1 mg/liter, a lter will have to be used.
Consult factory with water analysis
Check between Test Point #3 and ground with a multimeter set on VDC scale. Conrm the
circuit board is seeing low current ow (<2.8 VDC). Proceed to next step.
If on initial ll, unit reaches less than 70% of rated capacity (2.8 VDC on Test Point #3),
adjust the drain threshold pot, “% adj.” (R18), down 2-3%. Manually drain the unit down
completely and add ½ Alka Seltzer tablet via the ll tee(GT-120). Restart the unit while
monitoring the amp draw. Fill unit ¼ full and turn “off” for several minutes to allow tablets to
dissolve. Restart unit. If amperage rises rapidly, it may be necessary to dilute the water. If
amperage rises slowly, add another Alka-Seltzer tablet.
Check that drain valve is sealing properly.
Check the water conductivity and consult the factory.
Check cylinder ll interface connections.
Check cylinder connections. (See Figures 6A-6D, page 10.)
Check items in next troubleshooting tip concerning foaming.
Check amperage between cylinder full electrode and cylinder full interface terminal #1. If it
is greater than 7.0 mA AC, take a ll water sample and consult the factory.

Problem/Symptom Reason - Correction
Water “foaming” inside the cylinder.
Cylinder lls and overows Check cylinder wiring. (See Figures 6A-6D, page 10.)
Unit turned on, lls to full amp
draw, stops lling, and after a
delay, the circuit breaker trips and
the service light comes on.
Unit cycle “on” and “off” rapidly Check location and setting of high limit humidistat
Cabinet leaks Check for loose connections
Check drain valve and ensure that water drains freely. If necessary, clean or replace valve if
defective.
Check water supply. If it is commercially softened, either increase the drain threshold (R18)
to 92% or reconnect the unit to raw water. Drain and restart the unit. If the unit is connected to a hot water line, reconnect to the cold water line. (3.68VDC)
If steam line is hard copper, drain cylinder and test unit operation disconnected from steam
line to ensure ux from solder joints is not causing foaming.
Observe the ll tee(GT-120). If water is going down the overow and the water level is low:
Check to ensure that static pressure in the duct is not forcing water down the overow
instead of allowing water to enter the cylinder.
Adjust the ll metering valve to regulate the water ow to the cylinder. (Figure 5.)
Unit lling slower or at the same rate as it is boiling off, causing over concentration and
foaming. Fill rate must be increased. Open metering valve.
If the ll valve is already fully open, get a water analysis and consult the factory.
Check wiring of cylinder full interface.
If more than 1.9 mA AC is passing between the cylinder full electrode and interface terminal #1, and when placing multimeter between terminal #3 and ground yields approximately
negative 11 VDC, replace the interface.
Replace the circuit board.
Consult the factory after obtaining a water analysis
Use the “On-Off Drain” switch to drain the cylinder. Turn the capacity adjustment pot(R39)
on the main circuit board to 80% and restart the humidier. (3.2VDC)
Check the drain valve and clean or replace if necessary.
If the drain valve doesn’t come on before the service light illuminates, replace the main
circuit board.
