I. INTRODUCTION
The Herrmidicool system is an in-duct air/water atomization
system designed to introduce atomized water into the
airstream. The unit uses a native BACnet controller that
responds to an analog 0-5 VDC demand signal to start the
humidication process. An input for proving airow prior to
starting the system is provided as well as alarm indication.
The touchscreen display allows the operator to interact with
the system. Network communications are available to allow
system monitoring and control.
II. OPERATIONAL CHARACTERISTICS
Upon an increase in demand signal above 20%, the controls
will energize the compressed air solenoid valve. An air
pressure switch will close if sufcient air pressure is present
to allow for proper atomization. When the air pressure switch
contacts close, the water solenoid valve will energize and
atomization will begin. Each nozzle is equipped with a clean
out pin that helps keep the water orice clear of mineral build-
up each time the nozzle is cycled. Periodically, the controls
will de-energize the water solenoid valve in order to actuate
the clean-out pin to keep the water orice clear. During
operation if the air proving switch contacts open, the system
will stop. If the system on/off switch is opened the system
will stop. See the Controls section for additional details.
Allowable Operating Conditions
Ambient Temperature: 40°-120°F (4°-50°C)
Ambient Relative Humidity: 0% - 90%
Line Voltage: -15% to +10% Nominal
Frequency: 50/60 Hz
Supply Air Pressure: 60-200 psig
Supply Air Quality: Filter clean and dry to 35°F dewpoint.
Supply Water Temperature: 40°-100°F (4°-38°C)
Supply Water Pressure: 50-100 psig
Supply Water TDS less than 50 ppm: Consult Factory
with water analysis and application data prior to selecting
equipment.
NOTE: If units are mounted in outdoor enclosures, conditions
inside enclosure must be maintained as listed above.
III. MOUNTING
The Herrmidicool system consists of two basic components:
the control cabinet and the atomizing-head manifold
assembly. The control cabinet should be mounted so that the
water outlet of the control cabinet is level or below the water
manifold in the air handler. Air vents must be mounted on
any loops necessary to connect the cabinet to the manifolds.
Minimum Cabinet Clearances:
Top: 1” Bottom: 12”
Sides: 2” Front: 4”
32” Working Area Clearance
Hang the cabinet on the wall or unistrut mounting frame.
Two keyhole slots and two additional mounting holes are
provided. Be sure the unit is level and mounted directly
to the wall to wood studs as least 2” thick (or equivalent).
The atomizing head manifolds consisting of air manifolds,
atomizing heads, water manifold and unistrut brackets are to
be located as shown on specic layout drawings with each
job. Typically, a “unistrut” style mounting structure is eld
fabricated to support the atomizing manifold.
Manifold Installation:
1. Install the air/water manifolds per the layout drawing
included with this package.
2. Use only copper, plastic or stainless steel piping as
specied in your print package.
3. Keep runs between control cabinets and heads as short
as possible.
4. Piping runs between control cabinets and manifolds
should be as direct as possible. If loops are unavoidable,
automatic air vents must be supplied and installed.
IV. PLUMBING
Each cabinet has an air inlet, water inlet, air outlet(s), water
outlet(s) and a drain. All air connections are ½” and all water
connections, including drain, are ½”.
1. Drain loop must extend 3” above highest location of
heads or water outlet port on cabinet. This loop allows water
pressure to be relieved on system shutdown.
2. Piping from control cabinet to manifolds without draining
should be ¾” for the air and ½” for the water piping unless
otherwise shown on your job specic drawings provided for
your project.

Herrmidicool

www.trioniaq.com
NOTE:
Inlet water pressure must be in range of 50-100 psig. Consult
the factory if you are outside this range.
Supply Power
1. Supply power of 120 VAC, 5 amps is required.
2. Field wiring of the main power supply is connected directly
to the line power-lter in the control cabinet. A ground lug is
provided for the ground wire.
3. Install external overcurrent protection and provide wiring
in accordance with the NEC, state and local codes.
4. Power supply must be “clean;” free of spikes, surges and
sags; +10%, -15% of nominal. Ground should be true earth
ground.
V. CONTROLS
Controls may be supplied by the factory or others. The following
information applies to all controls factory supplied or furnished by
others. All external electrical control circuits are to be connected
to the unit using the terminal strip located in the electrical
compartment. Field wiring from humidistat to humidier and
between safety devices, such as high limit humidistat and air
proving switches, should be 18 AWG stranded or 20 AWG solid
wire. Wall devices should be mounted at a height similar to
that of a typical thermostat and should be located in an area
that will provide good representation of the overall space being
humidied. Do not mount wall devices directly in the air stream
of a supply grille or room distribution unit.
Duct control devices should be mounted in a location where
the humidity and temperature are uniform, usually the return
duct.
Duct high limit devices should be mounted downstream of the
evaporative surface far enough that under normal conditions
in the air stream, the water has been completely evaporated,
typically 10 ft. The device should be located such that it can
sense humidied air as it approaches saturation. Do not
mount in dead air spaces such as inside of comers.
Air proving devices should be mounted so that they sense
airow (or the absence of it). Wire the device so that it closes
when airow is present and will open when there is no airow.
The purpose of the device is to prove that airow is present
before mist is distributed into the duct.
Your application specic wiring diagram, included with this
package will detail exact led wiring connection points for
your unit.
Control Circuit Connections
On/Off (OPTIONAL – Limited Application)
1. Control Input - Unit will operate with any two-position
device. Demand for humidity will close the contact.
2. Limit Input - Unit will operate with any two-position device.
The humidistat contact will open on humidity rise.
VI. CONTROL BOARD OPERATION
The Herrmidicool system is equipped with a native BACnet
controller. When power is applied to the system, the display
turns on and displays the STANDBY screen (shown below).
The STANDBY screen displays System Enable Staus
(enabled or disabled), the System Output, and the cumulative
hours of runtime. The number indicated represents the total
number of hours that the system solenoid valves have been
energized and spraying water for humidication.
Touching the screen anywhere will take you to the HOME
screen (shown below).
The HOME screen is a gateway to other screens. The
system may be Enabled or Disabled by touching the box next
to System Enable Status. A window will pop-up and the user
can make their selection. Upon being enabled, the system
will respond to increases or decreases in the Demand Input
WARNING
Do not mount any controls inside the unit or tap power
from any location in the unit, except as stated in these
instructions. Do not place objects near the cabinet.
Do not attach to dry wall without studs.
CAUTION
Any minerals that are in the water will be injected into
the airstream. Your application/process may require
some means of air or water ltration to complete a
successful application. Consult the factory if you
should have any questions. Softening the water
only increases the TDS level.

(0-5 VDC). When the demand is greater than 20% (1 VDC),
the system will enable the compressed air solenoid valve;
starting the system. On any screen, the user may return
to the HOME screen by touching the house pictured in the
upper left of the screen.
The STATUS, PARAMETERS, & ALARM, screens are
described below.
The STATUS screen (shown above) displays the state of
the inputs and outputs. The demand Input displays the
percentage of demand being supplied to the controller input.
This screen will show the user the status of the inputs and
ouputs.
The PARAMETERS screen (shown above) allows the user
to change the way the system works regarding nozzle
cleanout. If enabled, at the interval set by the parameter,
the water solenoid will de-energize for the duration set by
the Cleanout Duration parameter. If Nozzle Cleanout is
disabled, the system will operate continuously whenever
there is a demand input.
The ALARM screen (not shown) allows the user to check the
status of active alarms and alarm history. Whenever the red
exclamation point is shown on the screen, there is an active
alarm. If the exclamation point is gray, there are no active
alarms. The user may go to the alarm screen at any time
to check the history of alarms that have returned to normal
conditions.
There are two possible alarm conditions that may present
themselves during operation. They are the Air Proving Switch
and the Compressed Air Pressure Switch. After a demand
is present and the unit attempts to start, if either of these two
switch inputs fails to close, the unit will shut down and an
alarm will be present. Once the condition is corrected, the
unit will commence normal operation automatically.
The SETUP and MODULE STATUS screens are gateways to
lower level settings that should only be adjusted by a system
administrator. CHANGING SOME OF THESE SETTINGS
MAY RENDER THE FACTORY WARRANTY VOID
When touching SETUP or MODULE STATUS, the
administrator will be prompted for a password. Enter 2222 to
log in to the controller. Network settings, date and time may
be adjusted via the SETUP screen. The MODULE STATUS
screen should not be used without the direction of the factory.
The CLOCKSET screen allows the date, time, and daylight
savings time details to be programmed into the controller.
Unless the date & time are set, the controller will report
incorrectly on the ALARM screen.
VII. START-UP CHECKLIST
This Check List is intended to highlight critical installation
points. A poor installation frequently results in start-up
difculties, and always results in less than ideal operation of
the humidier.
1. Insure all valves and valve cocks through the system
(especially at every head) are shut-off.
2. Electric power is connected to the control cabinet per the
diagram.
3. All sensors, airow switches and external inputs are
connected to the cabinet.
4. Air compressor is primed, oiled and air supply is
connected to the cabinet.
5. Air supply line has been purged and blown down to
remove any installation dirt.
6. Air supply line has been charged, leak tested and has a
minimum of 60 psi pressure to the cabinet.
7. Water supply is connected to the cabinet and has been
purged and blown down to remove installation dirt.
8. Water supply is charged and leak tested and has a
minimum of 50 psi pressure at the cabinet.
9. Drain loop has been connected to the bottom of the
cabinet and has been plumbed to an open drain.
10. Drain piping is installed with a loop a minimum of 3”
above atomizing heads and all piping after the cabinet.
11. All water piping from the cabinet to the manifolds is level
and without loops or automatic oat type air vents have
been installed at high points to remove trapped air.
12. Air handler is completely operational and has been

VIII. START-UP
After all checklist items are completed (and the total
installation is complete) the Herrmidicool system is ready to
start. Refer back to the Start-Up Checklist prior to Start-Up
below.
IMPORTANT:
Before scheduling factory start-up, please have any issues
relating to the “Check List” resolved. If additional trips are
required, additional start-up costs will be incurred!
1. Blow out air and water lines to the control cabinet.
2. Set all controls to their lowest setting (control and limit if
applicable). This allows the system to be turned “on” without
the atomization process being started.
3. Once the units get the signal to run and unit is turned
“on,” the air solenoid will energize within 5 seconds. Once
the air pressure switch detects sufcient air pressure, the
water solenoid will open.
4. With individual air and water valves at atomizing heads
closed, blow out the air and water lines through the hose
bibs.
5. A factory-trained technician will complete the balance of
the start-up.
If used, blowdown tanks, air vent check valve assemblies,
and balancing air regulators are installed as shown on the
installation layout drawing provided with this manual.
Call your local TRION/HERRMIDIFIER representative to
schedule a trouble-free start-up. Minimum two week notice
is required.
IX. ATOMIZING HEAD OPERATION
The HERRMIDIFIER atomizing heads operate with the
water pressure higher than the air pressure. As air enters the
atomizing head, it ows in a centrifugal motion inside the air
nozzle and outside of the water nozzle. As the water enters
the atomizing head, it creates pressure against the diaphragm
and compresses the spring located on the opposite side of
the diaphragm. The motion of the diaphragm pulls the water
seat away from the bottom of the water nozzle allowing water
to ow through the water nozzle. As the water exits the water
nozzle, it become atomized by the compresses air inside the
air nozzle and exits the atomizing head as a ne spray.
X. PRESSURE SETTINGS
IMPORTANT: The air and water pressures to the atomizing
head should only be adjusted when the humidier is at full
output. In other words, when the modulating water valve is
100% open the controls are calling for maximum capacity.
Do not attempt to adjust the air and water pressure settings
at any other time. The instructions below assume that the
atomizing heads are installed at the same elevation as the
water control section. Adjustment from this standard must be
made to compensate for any elevation differences between
the water control section and the atomizing head manifold.
1. Set the air pressure at 30 psig.
2. Set the water pressure at 33-38 psig according to the
atomizing head capacity as listed below:
a. 6 lb/hr. 34.5 psig
b. 8 lb/hr. 38 psig
c. 10 lb/hr. 33 psig
d. 12 lb/hr. 34.5 psig
e. 15 lb/hr. 37 psig
The water pressure settings listed above will allow the
atomizing heads to perform at their rated capacity (lb/hr.).
It may be desired to deviate slightly (1-2 psig) from the
standard settings in order to enhance performance. Slightly
lower water pressures will result in a ner atomized spray
(smaller droplet size). Be aware that any adjustments such
as this will also reduce the rated capacity of the heads. Use
caution accordingly.
XI. MAINTENANCE
• Air Compressor – follow manufacturer’s recommended
instructions.
• Atomizing Heads – clean dust and debris from outside of
heads as required. If raw water is used, we recommend
removing the atomizing nozzles and strainer screens once
a year for disassembly and cleaning. DO NOT use a wire or
other foreign object to clean nozzle as this could ruin orice.
• Air & Water Lines – blow out once a year. Check joints for
leaks once a year.
• Strainers on air/water control sections should be cleaned
once a year.
• Sensors/transmitters should be checked once per year
• Solenoid valves should be checked once a year for proper
operation and closure.
XII. EXTENDED SHUTDOWN
After an extended shutdown, air and water lines should be
blown out prior to resuming normal operation
XIII. ATOMIZING HEAD ADJUSTMENT
The atomizing heads are factory adjusted and tested. Typically,
no adjustment is required unless the atomizing heads have
been disassembled for maintenance. Do not adjust individual
atomizing heads to reduce capacity or enhance performance.
This is done only by changing the operating pressures for the
entire system.
1. Turn the Herrmidicool System on to full output and check
that the air and water pressures are correct.
2. Remove the cap from the back of the atomizing head.
3. Using a screwdriver, slowly turn the spring tension nut
clockwise until the atomizing heads stops spraying.
4. Note the position of the spring tension nut.
5. Back the spring tension nut out two full turns
counterclockwise.
6. If head is not spraying at start of procedure, back out spring
tension nut until head starts to spray and then begin step 3.

XIV. NOZZLE TROUBLESHOOTING
A. Heavy spray pattern (droplets too large)
1. All heads – This is caused by incorrect air and water
pressure settings. Review settings and adjust as required.
Never allow air pressure to exceed the water pressure.
2. Individual Heads – These heads are not getting enough
air for one of the following reasons:
a. Foreign matter may be clogging the screen (AH-21) in
the air strainer union of the head. Clean or replace it.
b. One or more of the heads may have been improperly
adjusted or the individual shut-off valve may be throttled.
No valves should ever be throttled. Readjust if necessary.
c. Water nozzle (AH-942) orice may have been enlarged
due to bent cleaning needle. Replace parts as required.
d. Atomizer nozzle (AH-941) orice may have been
enlarged due to improper cleaning or dirty air. Replace
part as required. Standard air orice sizes for the various
heads are as follows.
6 lbs/hr 0.95 mm
8 lbs/hr 1.10 mm
10 lbs/hr 1.15 mm
12 lbs/hr 1.35 mm
15 lbs/hr 1.45 mm
B. Spray pattern too light at full capacity
1. All heads – This is caused by incorrect air and water
pressure settings. Review settings and adjust as required.
Never allow air pressure to exceed the water pressure.
2. Individual heads – These heads are not getting enough
water for one of the following reasons:
a. One or more of the heads may have been improperly
adjusted or the individual shut-off valve may be throttled.
No valves should ever be throttled.
b. Foreign matter may be restricting water ow in the
water nozzle (AH-942). Turn off the air and water valves
at the head.
Remove the atomizer nozzle and water nozzle. Blow
water nozzle with air. Do not use wire or other hard
object that will score the inside of the nozzle.
C. Sputtering heads – air pressure at the atomizing heads
exceeds water pressure.
1. Adjust air and water pressures to correct operating
pressures.
2. Normally open drain solenoid on water control section
may have a malfunction allowing water to leak into drain
line during operation. Solenoid valve seat may have
foreign matter under the seat causing it to leak. Solenoid
may have defective seat.
D. Inoperative heads (all heads)
1. The atomizing heads may be shutdown because the
system controls and setpoints are satised.
2. If the desired RH level has not been achieved, check
calibration of the controls and adjust as required.
3. Air and water supply valves are not open.
4. No supply air pressure. If supply valves are open and
the gauges indicate no air pressure, check compressed
air source.
5. No power to the air and water solenoid valves. Check
controls and control cabinet fuses.
Individual heads
6. Be sure air and water valves to the atomizing heads
are open.
7. Possible defective parts inside atomizing head. Shut-off
air and water valves to the head and remove head from the
system. Disassemble and examine internal parts. Repair
and reassemble as required. Rebuilding kits are available
from your local TRION/HERRMIDIFIER representative.
Perform a complete restart and readjustment of the
atomizing head upon reassembly and repair.
