WARNING!!
PLEASE TAKE NOTE OF THE FOLLOWING
1. BEFORE STARTING
PLEASE READ THIS GUIDE ENTIRELY BEFORE BEGINNING INSTALLATION
ALSO, READ SUPPLEMENTAL INFORMATION RELATING TO OPTIONAL CONTROL EQUIPMENT
CRANKCASE OIL PLUG
The pump module crankcase vent has been plugged to prevent accidental oil leakage during shipment. Remove
the plug and replace with the supplied vent cap before operating pump unit. Failure to do so will cause oil leaks.
OIL LEVEL
Check that the oil level appears 1/2 way in the sight gauge or within range on the dipstick in the pump head.
INLET WATER SUPPLY PRESSURE.
When the pump module is running, it must be supplied with an inlet water supply of
NEVER LESS THAN 20 P.S.I. (1.40 BAR) AND NEVER MORE THAN 90 P.S.I. (6.20BAR)
•INLET WATER SUPPLY PRESSURE SHOULD BE STEADY AND SHOULD NOT BE ALLOWED TO FLUCTUATE OUTSIDE OF THESE
RANGES.FAILURE TO DO SO CAN RESULT IN DAMAGE TO EQUIPMENT AND IS NOT COVERED BY WARRANTY.
•IF WATER PRESSURE DROPS BELOW 20 PSI, THE PUMP WILL SHUT OFF AND THE FAULT LIGHT WILL COME ON. SEE SECTION
9SYSTEM OPERATION FOR FUTHER INFORMATION.
OIL CHANGE INTERVAL
The crankcase oil must be changed after the first 50 hours of operation and from then on, once every 500 hours.
•SYNTHETIC 75W-90 GEAR OIL IS RECOMMENDED FOR ALL APPLICATIONS (MOBILE ONE OR EQUAL)
•SECONDARY CHOICE SYNTHETIC 15W-50 MOTOR OIL MAY BE USED FOR ALL APPLICATIONS (MOBILE ONE OR EQUAL)
HIGH PRESSURE FITTINGS
The system operates at 1,000 P.S.I. (70 bar) and should always be shut down when working on fittings or manifold
line. Extreme caution should always be exercised when working with high pressure water. Always wear safety glass
when working around fog equipment.
INLET WATER SUPPLY PLUMBING MATERIAL
Only rated and approved brass fittings or stainless steel fittings should be used to make plumbing connections. The
use of galvanized or steel pipe fittings can cause system failure, nozzle blockage and pump damage.
FLUSHING THE SYSTEM
Before pressurizing the system, flush all plumbing and atomization lines thoroughly to purge any residual debris.
Please refer to the startup section 7 of this manual.
TEFLON TAPE
When using Teflon tape on NPT threads, leave 1 or 2 of the starting threads showing. This will prevent pieces of
Teflon tape from entering the system, which could cause blockage or damage.

IBEX 8 Nozzle SMALL FRAME_June 2020 June 20 Page 6 of 41
WATER QUALITY
2. WATER QUALITY
To obtain the best performance, special consideration should be given to the quality of water used in a MicroCool fog
system. For more information about Water Quality, consult a MicroCool specialist.
MicroCoolIS NOT RESPONSIBLE FOR NOZZLE BLOCKAGE DUE TO POOR WATER QUALITY.
TOTAL DISSOLVED SOLIDS COUNT
Water with total dissolved solids (TDS) counts of greater than 500 parts per million (PPM); water with high calcium
and magnesium carbonate levels, or water with pH levels below 6.7 and above 7.5 may not be satisfactory and could
lead to excessive nozzle blockage and the need for nozzle maintenance.
WATER ANALYSIS
If there is any doubt about water quality, a water analysis is recommended. Of major interest is the water’s Langelier
Saturation Index (SLI) together with other items such as hardness and TDS. A slightly negative, or neutral, Langelier
index is preferred, whereas a positive index may indicate a tendency to form calcium carbonate deposits in the lines
and nozzles.If using city water, an analysis should be available from the city/town water department. If in any doubt,
please contact your MicroCool representative for further information.
WATER TREATMENT
Generally speaking, most municipal water is suitable for atomization. Well water, river water and the like should be
tested before atomizing. If an analysis indicates any unusually high levels of undesirables’ proper treatments are
available. MicroCoolcan supply a variety of water treatment systems. Please contact MicroCoolfor further
details.
ULTRAVIOLET WATER PURIFIERS
Optional ULTRAVIOLET high intensity light purifiers can also be installed on the inlet water supply to sterilize the
system water. By bombarding the water with UV light, dangerous pathogens, spores and germs are destroyed. UV
systems must be regularly serviced to maintain the correct high intensity output.
REVERSE OSMOSIS WATER TREATMENT
MicroCool offers optional comprehensive reverse osmosis packages for all applications. Units are available for large
scale industrial as well as domestic installations.
Reverse Osmosis units incorporate a semi-permeable membrane that micro-filters the water to 0.0001 microns
removing bacteria, viruses, aqueous salts and metal ions. By eliminating these from the supply water, MicroCool
ensures that clean, hygienic water is used in each system. Clean water will also reduce nozzle blockage, foul odors
and white “chalky” deposits on material close to the fog spray.
MicroCool reverse osmosis systems are designed specifically for each application. Please consult with MicroCool
specialists for more details.

IBEX 8 Nozzle SMALL FRAME_June 2020 June 20 Page 7 of 41
3. INSTALLATION OF THE PUMP MODULE
Installation Procedure:
•Determine pump module location
•Identify water supply/connection for the system
•Determine routing of the high pressure manifold from the pump.
•Establish drainage location from the pump.
•Verify correct electrical power supply to the pump.
•Determine all of the above for optional Equipment - Zone Controllers, Temperature/Humidity Controllers, Reverse
Osmosis, UV sterilizers, etc...
POSITIONING THE PUMP MODULE
The pump module requires a flat level surface. Position selection will largely depend on
the availability of power and water, but remember the points outlined on the previous
pages as the terms of the pump warranty depend upon it.
A concrete floor or a concrete slab is ideal. Attach the supplied adjustable feet and plugs
to the legs of the pump as shown in the photograph (right). Using a level, make sure that
the IBEX unit sits as level and plumb as possible.
WATER SUPPLY AND CONNECTION
The water supply should be capable of 1.5 times the maximum flow of the pump as shown in the table below.
Pump Model & Flow

IBEX 3000 (2.50gpm)
3.75
14.25

Correct water pressure and flow rate are essential to pump operation. All pump modules require a minimum of 20
P.S.I. (1.40 BAR) and a maximum of 90 P.S.I. (6.20 BAR) while in operation. The pressure should always be constant
and not fluctuate outside these ranges, especially on system start up. All pump modules are equipped with a low
pressure inlet water fault delay timer, which allows small drops in pressure, but will ultimately “fault off” if low pressure
is present for more than a few seconds.
Ensure that either copper or PVC pipe is used to provide the
correct water supply to the IBEX unit. Never use steel or
galvanized steel fittings. Always use the largest diameter pipe
practical.
DRAINAGE FROM THE PUMP
After the pump module shuts down, the water remaining in the manifold lines will drain out through the pump module
and through the end of the atomization lines on some lines. Ensure that the drain outlet is routed to a suitable
drainage point to avoid flooding.A 6 foot (1.8 M) low pressure drain tube is provided for this purpose. This hose
can be extended as necessary.

IBEX 8 Nozzle SMALL FRAME_June 2020 June 20 Page 8 of 41
4. PUMP MODULE POWER SUPPLY
After all water and plumbing connections have been completed, a licensed, qualified electrician should connect the power
supply to the pump. It is important to follow the National Electrical Code (NEC), as well as any local codes to ensure a
safe installation.
CAUTION!
If the pump unit will be powerd by a generator at any time, a properly sized line reactor needs to be installed prior to
the pump unit to eliminate voltage spikes. If this is not done, the Variable Frequency Drive (VFD) & procesor could
be damaged and warranty may be voided.
INSURE ELECTRICAL SPECIFICATION
Establish that the circuit to be used to power the pump module is of the same electrical specification as the pump
module. The IBEX electrical specification can be found on the serial number label or from the electrical wiring
diagram adhered to the inside cover of the electrical enclosure on the pump module.
4.2.1 The circuit to the pump module must be dedicated and properly sized to carry the electrical load placed upon
it by the pump motor. Please refer to the MicroCoolEngineering Manual or electrical data plate on the
motor to determine the amperage draw of the Ibex pump module.
4.2.2 The power supply to the pump module must be hard wired directly to a fused disconnect box. If the power
supply cannot be directly wired to a disconnect box, then it should be hard wired, using a junction box, into a
suitable circuit with a disconnect box located elsewhere. This applies to either single phase or three phase
applications.
4.2.3 After verifying all of the above, power should be taken from the disconnect box/junction box to the terminal
strip located inside the electrical enclosure mounted on the pump module. We recommended that the correct
sized wiring be in conduit (preferably liquid tight); make the final connection to the high voltage terminal strip.
ELECTRICAL CONTROLS
The high voltage motor electrical supply must be connected to the pump module inside the control box. The low
voltage control wiring must also be connected inside the control box. We recommend that a LICENSED
ELECTRICIAN IS USED FOR ELECTRICAL CONNECTIONS.
ELECTRICAL CONNECTIONS/ HIGH VOLTAGE
Open front cover to connect the high voltage wiring to pump controls. Connect high voltage to TB1(terminal block
1) electrical strip in the control box. There is a conduit connector provided for connecting conduit to the side of the
control box.

External (remote) start connections must be made to TB1 Terminals 1 & 2. Note that this connection is powered by
a 24V DC voltage from the pump controller. Adequate care must be taken NOT to connect a different or separate
power supply to these terminals as serious damage could occur. If in doubt – please contact the factory for a
suitable relay or conditioner.
WARNING: The control box is completely wired for immediate operation. After high voltage wiring is connected
and the unit is supplied with proper water pressure, pressing F1 will immediately
activate the pump operation.
5. Standard wiring diagrams for MicroCoolIBEX pump modules
An as-built wiring diagram has been added to the back of this manual.
6. Principle of the VFD system on the IBEX pump unit
VARIABLE FREQUENCY DRIVE
6.1.1 A VFD (Variable Frequency Drive) controls the speed of the electrical motor (and subsequently the pump
head) by changing the Frequency (Hertz). The IBEX pump module has a Pressure Transducer unit mounted on the
high-pressure (discharge) side of the pump that transmits the water pressure back to the control unit.
6.1.2 The controller is pre-set to maintain a pressure of 1,000 psi (70 Bar) at the discharge of the pump.
6.1.3 As the water flow rate of the system changes (for example with more or less nozzles in operation) the
controller will increase or decrease the motor speed to maintain the required pressure (1,000 psi / 70 Bar).

IBEX 8 Nozzle SMALL FRAME_June 2020 June 20 Page 10 of 41
The controller is capable of increasing the speed (frequency) to a maximum of 50 Hz. The rate of change is
governed by programming within the drive to reduce motor, pump, and equipment wear.
6.1.4 The minimum speed of the motor is also regulated by the controller. At very low rpm, the pump may be
moving too slowly to adequately distribute the oil in the pump reservoir. Damage to the pump may occur.
The minimum speed (frequency) is set at 15 Hz to protect the pump unit from oil starvation.
6.1.5 For more details on the VFD drive, the readings and fault status, refer to the WEG Drive supplement at the
end of this manual.
7. MicroCool IBEX - STARTING THE SYSTEM
START UP
7.1.1 Install UV bulb prior to start up. (If UV is provided)
7.1.2 The system must be primed and flushed before pressurization.
This removes any contaminants such as dirt, brass filings or
Teflon tape that have found their way into the system.
7.1.3 Turn on the water supply to the pump module. The inlet or low
pressure gauge should read at the very least 20 PSI (1.4 BAR)
indicated by the green area of the dial. If the water pressure is
not sufficient, do not try to start the pump. The water pressure
problem must be corrected first.
7.1.4 To prime the pump module turn on the power supply to the IBEX module, open the electrical enclosure,
switch the circuit breaker to the on position. Once the VFD indicates “RDY” and the PLC is illuminated,
press F3 and F4 simultaneously. This will start the prime sequence of 30 seconds. The pump is now ready
to be started.
7.1.5 To start the IBEX module press F1 (run in Manual). The pump module will now run, there must be between
20 PSI (1.4 BAR) and 90 PSI (6.2 BAR) of pressure available to the pump at all times. Note-should the
water pressure drop below the factory preset of 20 PSI, there is a 3 second delay before the system goes to
“FAULT”. Refer to section 9 to reset.
7.1.6 The pump motor RPM will ramp (increase) up to the maximum speed (50 Hz) to fill the system. Do not worry
if the pressure does NOT reach 1,000 PSI (70 BAR) at this time (during flush sequence).
7.1.7 Let the module run for 2-3 minutes making sure that there is a good flow of water running out the end of the
atomization lines. Lines may have to be flushed in groups, with larger systems, to ensure adequate system
flush.
7.1.8 When finished flushing, press F3 (Stop) to stop the pump module.
7.1.9 The system is now flushed and ready for the pressurization procedure.

IBEX 8 Nozzle SMALL FRAME_June 2020 June 20 Page 11 of 41
8. PRESSURIZING THE SYSTEM
8.1 ABOUT PRESSURE REGULATOR
The regulator is set as a safety valve should the system pressure exceed IBEX: 1,100 PSI (75.8 Bar). At
extremely low flow, the regulator will bypass water back into the pump head as the VFD drive has
reached its minimum Frequency (Hertz).
8.2 PROCEDURE TO RESET THE PRESSURE REGULATOR
ABOUT THE PRESSURE REGULATOR: ADJUSTMENTS SHOULD NOT BE MADE TO REGULATOR. ONLY
FOLLOW THIS RESET PROCEDURE IF REGULATOR IS REPLACED OR WHEN REPLACING PUMP HEAD.
Safety glasses must be worn when adjusting pressure. Always keep guards and covers in place.
NEVER DISASSEMBLE THE REGULATOR UNDER PRESSURE!!!
If for any reason the regulator is adjusted, or changed, follow this procedure to reset the correct adjustment.
1.
Press F3 (IBEX) to turn off the pump.
2.
Turn off the electrical supply at the disconnect switch to electrically isolate the pump.
3.
Locate the pressure transducer and unplug the electrical lead by squeezing the clip.
4.
Restore the power and start the unit by pressing F1.
5.
Adjust the regulator by turning*clockwise or counter-clockwise until the pressure gauge indicates 1,100 psi
(75.8 Bar) for IBEX. When the pressure is steady at 1,100 make sure that the “Jam Nut” is tightened to lock
the adjustment in position. [*Clockwise: increase pressure. Counterclockwise: decrease pressure.]
6.
Press F3(IBEX) or F2(FOCUS) to stop pump, shut off power. Plug electrical lead back into transducer,
restore electrical power.
7.

Drain/Pressure Relief Valve Time
The drain/pressure relief valve time is the time setting that determines how long the drain valve remains open after
pump unit shuts down. This valve can be used to only relive the nozzle line pressure or relieve the nozzle line
pressure and drain the system. If only pressure relief is required then a short time of 10 – 15 seconds is adequate, if
the system is required to drain completely then a longer time setting would be required, depending on the system
size and length of manifold lines.

3. To enable the cycle timer feature the “CYCLE” “Switch=off” needs to be set to “Switch=on.
4. “CYCLE T” settings are represented as “TH” as on time and “TL” as off time.
5. The cycle/pulse feature will cycle/pulse the pump module while operating in “Auto”
CAUTION-do not set the off cycle time shorter than 1 minute in order to avoid motor heating.
Disabling F1 “Manual Run
If the system includes zone controllers or zone valves, and is run in Auto, F1 should be disabled. By
disabling F1, the pump system has to be started and stopped by a remote input from a zone controller, or
another control device, and the pump would be in “Auto Ready” (press F2).
WARNING, operating the pump unit in F1 “Manual Run” with zone controllers or zone valves installed in the
system, could cause the pump to dead-head resulting in damage to the pump unit that would not be
covered under warrantee.
1. F1 disable is located in “Set Param” and is labeled as “F1 DISAB” the default setting is off. The soft key
settings represent:
a. Off = F1 is enabled
b. On = F1 is disabled
2. To access, enable and set F1 operation, follow the steps in 9.2 “Setting Axillary Parameters”

Setting Internal Temperature and Humidity Controls (Optional Upgrade)
1. If this upgrade was ordered with the system, temperature and humidity control will be available in
the controller.
2. To access, enable and set the temperature and humidity control, follow the steps in "Setting
Auxiliary Parameters”
3. To enable the temperature and humidity control, “TEMP & HUM” switch needs to be set from
“Switch=off” to “Switch=on”.
4. “HUMID SP” represents the humidity set point. To enter the set point, set the “off=**” to required
humidity level and set “on=**” to 0%. Example: if required humidity set point is 35%, set “off= 35”
and “on= 0”.
5. “TEMP SP” represents temperature set point, to enter the set point, set the “off=**” to required
temperature level in F°/C° and set “on=**” to at least 3° points above “off=**” setting. The difference
between the on and off setting is the hysteresis or dead band. Example: if required temperature set
point is 75°F with a 3°F dead band set “off=75” and “on=78”.
6. The temperature and humidity outputs are in series, so both the temperature and humidity contacts
needs to be closed for the system to run.
7. To view current temperature and humidity levels and set points, press “F4” once. The display will
revert back to the operation screen after 30 seconds.
Setting for Humidity control only:
1. Set the temperature set point to 33°F/0°C “off=33°F/1°C” and “on=34°F/1°C”. (This forces the temp
contact.)
2. Set the humidity set point to desired humidity to be maintained as described above.
3. The controller will start the pump system when the humidity drops below the set point.
Setting for Temperature control only:
1. Set the humidity set point to 100%. (This forces the humidity contact).
2. Set the temperature set point to the desired temperature to be maintained as described above.
3. The controller will start the pump system when the Temperature drops below the set point.
Setting for Humidity control with Temperature override:
1. Set the humidity set point to desired humidity to be controlled as described above.
2. Set the temperature set point to desired temperature, not to go below as described above.
3. The controller will start the pump system when the humidity drops below the humidity set point, but
will stop the pump if the temperature drops below temperature set point.
Setting for Temperature control with Humidity override:
Set the temperature set point to desired temperature as described above.
Set the humidity set point to humidity level not to exceed as described above.
The controller will start the pump system when the temperature rises above the set point, but will shut the
pump system off when the humidity set point is reached.
To view the VFD fault code:
All 380V to 575V IBEX pump units are installed with a panel door disconnect. In order to view status
information on the VFD display, it is necessary to defeat the door switch mechanism, and to open the
door in the ON position.
CAUTION! Opening the panel door in this manner does not remove power
from the internal electrical circuits.

1. First turn the black panel latch counter clockwise to release.
2. Using a flat screw driver turn the black screw release counter clockwise
about 1/8” and hold it in that position.
3. Pull the door open with the red disconnect switch in the vertical position.
4. Once the inspection is complete, close the panel door by simply holding the
red disconnect switch in the vertical position, push the door closed, and re-
latch the black door latch.
