Start-Up
After total installation is complete, the Herrmidicool system
is ready to start. Refer back to the Start-Up Checklist prior to
Start-Up below.
I
MPORTANT: Before scheduling factory start-up, please
have any issues relating to the “Check List” resolved.
If additional trips are required, additional start-up money
will be required!
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.
Control Mode:
• Mode 1 (On/Off) – Turn the dial to the Off position or
its lowest setting
• Mode 2 (Proportional) – Set the controller to send the
lowest signal in the range (i.e. 0 VDC in a direct
0-10VDC range).
• Mode 3 (P + I) – Set the “control setpoint” through
Menu 2 at least 11% below the “Control RH” display
in Menu 1.
3. Set the high limit to its highest setting (all control modes).
4. Set Control input to get the Herrmidicool System to
attempt 100% capacity as follows:
• Mode 1 (On/Off) – Turn to full “On” or highest
number possible.
• Mode 2 (Proportional) – set controller to send a
full signal (i.e. 10 VDC in a direct 0-10 VDC output
range).
• Mode 3 (P + I) – Set “Control Setpoint” through Menu
2 20% above “Control RH” as displayed in Menu 1.
5. 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 sufficient air pressure, the
water solenoid will open.
6. With individual air and water valves at atomizing heads
closed, blow out the air and water lines through the hose
bibs.
7. A factory-trained technician will complete the balance of
the start-up.
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 the orifice.
• 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.
Diagnostics
The Herrmidicool humidifier includes built-in diagnostics ca-
pability to identify potential problems, protect the system, and
minimize service/repair time. Should the system detect a criti-
cal condition, a “fault” warning will be displayed on the LCD.
Certain faults prompt immediate system shutdown to protect
the unit or ductwork. Other faults allow the unit to continue to
operate but alert the operator to potential problems that require
maintenance. Other faults, which are designed for initial system
tune-up or preventative maintenance, are classified as “non-in-
dicating.” These faults are viewed by pressing the “fault” key on
the control panel. The table reflects all of the faults the system
is capable of detecting. Please note, however, that certain faults
are unique to certain control modes or networked systems and
are only visible where applicable.
During operation, when an “indicating” fault occurs, the word
FAULT will be visible in the lower right hand section of the LCD.
The red fault light will also be illuminated.
If an “indicating” fault has been detected or a preventative check
is being performed, follow this procedure to determine the cause
of the fault:
1. The LCD must be in the MAIN MENU to access diagnos-
tics. Press “FAULT” key to determine the type of fault.
2. Press the up arrow to determine if there is more than one
fault.
3. If possible, correct the condition causing the fault signal or
plan corrective action.
4. Press “ENTER” to clear the fault signal from the display.
When “ENTER” is pressed, all faults registered in the unit
will be cleared. If the condition causing the fault is not cor-
rected, another fault signal will occur.
5. Under normal operating conditions, pressing the “FAULT”
button will prompt the following display:
NO FAULTS PRESENT
