Start Up
1. Start up the MistBuster by rotating the control
knob clockwise. Set the airflow at the
minimum airflow setting that will maintain
the proper negative pressure. In most cases,
the three o’clock setting on the speed
controller will provide enough airflow to
maintain negative pressure. This will reduce
noise and maintenance, and will increase
efficiency.
2. The performance indicator light should be on
when the blower is running.
3. Push the test button to momentarily short out the
collector on the electronic cells. Arcing indicates
that the cells are energized properly.
4. The coolant selector switch on the back of the
MistBuster is used to compensate for nuisance
arcing that occurs with some water soluble or
synthetics. Pull the knob out for the highest
voltage, if nuisance arcing occurs, push the
knob in.
CAUTION
1. Be extremely careful when working with
the electronic cell. The edges of the
collector plates and the ionizing wires on
the cell may be sharp.
2. When cleaning the cell, be sure to wear
appropriate protective gear, especially
goggles and gloves. Skin contact with
alkaline detergent solution should be
avoided. See warning label on the
detergent.
3. The electronic cell must be handled with
care to avoid damage.
The direct mount MistBuster captures mist
droplets from machine tools using either petroleum
or synthetic machining fluids. The collected fluids
drain directly back into the machine tool through
the inlet opening. This draining process actually
helps to keep the impingers and electronic cell
clean.
The mist impingers and electronic cell will need to
be cleaned periodically. The exact maintenance
interval is determined by each specific application.
Water soluble and synthetic machining fluids will
require more frequent cleaning than will petroleum
machining fluids. During the first few months of
operation, inspect the impingers and electronic
cell. When you have an excessive buildup on the
mist impingers and electronic cell, they will need to
be cleaned.
Parts Washer Method
The mist impingers and electronic cell can be
cleaned with a parts washer. Make sure that the
cleaning fluid used is aluminum safe and the
maximum pressure does not exceed 60 psi
[414kPa].
Manual Cleaning the Mist Impingers
Soak impingers in a solution of hot water and
alkaline detergent for 10-15 minutes. Thoroughly
rinse with hot water to remove any residual
detergent.
Manual Cleaning the Electronic Cell
1. Fill the wash tub with cell cleaning detergent
and hot water per the detergent
manufacturer’s instructions.
2. Immerse the cell in cleaner solution for five
minutes.
3. Thoroughly rinse the cell with very hot water.
Make certain no residue remains on the cell.
4. Inspect the collector plates for cleanliness.
Repeat wash procedure, if necessary. Check
for broken wires and bent collector plates.
The cell can be installed back into the
MistBuster. The indicator light may remain off
for the normal two hour drying time.
NOTE: If water-soluble machining fluids are
used, it would be best to coat the cell with AQE
Cell Coat after washing the cell. See the Parts
List section for the part numbers for the
detergent and cell coat.

Troubleshooting
INDICATOR LIGHT IS OFF AND MOTOR RUNS
1. Remove all electronic cells, close the access door and turn the unit back on. If the indicator light
remains out and the motor continues to run, replace the high voltage power supply.
2. If indicator light comes back on when the electronic cells are removed, there is a short circuit in
at least one of the electronic cells. Wash and inspect the cell. For instructions on how to wash
the cell see the routine maintenance section of the owner’s manual.
Inspect the cell for the following:
Damaged or bent collector plates
Damaged or bent ionizer grid fins
Broken ionizing wires
Dirt accumulation on the insulators
Dirt accumulation on the collector plates
Damaged or corroded electrical contacts
Small metal shavings from machining
Deformation of the cell
The collector plates are properly seated into the slots of the comb on the cell
Excessive corrosion on the cell
An ohmmeter may be used to check resistance between the outside frame of the cell
and both the ionizer and collector contacts. In each case, the resistance should be
infinite (open circuit). Anything that is bridging the gap or shrinks the gap between the
energized collector plates or the energized ionizing wires can cause the indicator light to
extinguish or constantly blink due to the electricity shorting out to ground. Occasional
snapping or the occasional light blinking is normal.
CAUTION
Make sure the power is off to the unit before attempting
to bypass the speed controller.

NOTE: The blower and motor in the MistBuster are integrated. The unit will not funcon unless
the door interlock switch is depressed (i.e. the filter access door is closed.)
INDICATOR LIGHT IS ON AND MOTOR DOES NOT RUN
1. Inspect the motor by checking to see if the motor spins freely by hand. If the motor does not
spin freely by hand check for obstrucons or replace motor as necessary.
2. If the motor spins freely by hand try spinning the motor clockwise or counterclockwise then with
the motor spinning turn the unit on. If the motor runs and the fan speed can be adjusted by the
speed controller replace the motor capacitor.
3. Try bypassing the speed controller by hooking the supply voltage going into the speed controller
directly to the wire that goes from the speed controller to the motor (see schemac). If the
motor works with the speed controller bypassed replace the speed controller.

Troubleshooting
4. If indicator light continues to flash even without the electronic cell(s) installed, clean or replace
the contact boards mounted in the cabinet. Note –clean the red, phenolic material of the
board, not the electrical contacts themselves.
5. If the indicator light blinks in either the water soluble or oil mode, and stops blinking when the
electronic cells are removed, there is a problem with at least one of the electronic collector
cells. Wash and inspect the cell. For instructions on how to wash the cell see the routine
maintenance section of the owner’s manual.
Inspect the cell for the following:
Damaged or bent collector plates
Damaged or bent ionizer grid fins
Broken ionizing wires
Dirt accumulation on the insulators
Dirt accumulation on the collector plates
Damaged or corroded electrical contacts
Small metal shavings from machining
Deformation of the cell
The collector plates are properly seated into the slots of the comb on the cell
Excessive corrosion on the cell
INDICATOR LIGHT IS OFF AND MOTOR DOES NOT RUN
1. Make sure the unit is getting power and is getting the correct voltage.
2. Check to make sure the interlock switch is working properly. Make sure there is voltage passing
through the interlock switch when the button for the interlock switch is depressed. With the
power disconnected to the unit an ohm meter can be used to check if the interlock switch has
continuity when the switch is depressed. The interlock switch has two sets of contacts that are
individually switched and will not have continuity between the two separated contacts. If there
is no continuity replace interlock switch as needed.
3. With the unit on, check to see if the power supply and motor are getting voltage. If the interlock
is functioning properly and there is no power reading to the power supply or motor, check
wiring and replace the speed controller as needed.

INDICATOR LIGHT IS CONSTANTLY BLINKING AND THE MOTOR RUNS
1. If coolant selector switch (in back on MB 500 and MB 850, in front on MB 2000) is in oil mode,
move coolant selector switch to the water-based mode.
2. If indicator light now stops flashing in the water-based mode, but flashes in the oil mode, there
is a short circuit in the collector fins of the electronic cell. See Figure 10 on page 20 for cell parts
identification.
3. If indicator light flashes in both the water-based mode and the oil mode, remove all electronic
collector cells, close the door and energize the unit again.

Troubleshooting
INDICATOR LIGHT IS ON AND MOTOR DOES NOT CHANGE SPEED
1. Adjust the speed controller fine adjustment. To get to the fine adjustment on the speed
controller pull the knob offthe speed controller and slide the silver plate behind the speed
controller knob up (there is no fasteners holding the speed controller knob or the silver plate
on). There is a small hole next to the main adjustment for the speed controller that you can
insert a small screwdriver to adjust.
2. If adju g the fine adjustment does not change the fan speed replace the speed controller.
INDICATOR LIGHT IS ON, MOTOR RUNS, AND MIST / SMOKE IS COMING OUT
THE EXHAUST
1. Try reducing the speed of the motor to increase the amount of me the electrosta cells have
to collect the mist / smoke.
2. If reducing the motor speed does not help and if the coolant selector switch is in the water soluble
mode,switch the coolant selector switch to the oil mode while the unit is not filtering mist / smoke. If
the light turns offor flashes when placed in the oil mode, go to the troubleshoo ng sec on for
when the indicator light is constantly blinking and the motor runs. The reason for switching the
selector into the oil mode is because in the water soluble mode the indicator light will not
indicate a short in the collector side of the cell.
3. If the applica on that the unit was installed in has changed (i.e. higher coolant pressure, shorter
cycle mes, machine has changed, etc.) the unit might not be able to handle the increased load.
INDICATOR LIGHT IS ON, MOTOR RUNS, AND MIST / SMOKE IS NOT BEING
EVACUATED / CAPTURED
1. Make sure there are no ob ons in the du g or the unit.
2. Make sure there is proper airflow. If the unit is installed too close to openings on the machine
cavity the unit will pull in fresh air from the opening and not move / draw into the unit from
where the mist / smoke is being generated.
3. If long lengths of duc ng / tubing are used the airflow can be dras ly reduced. The same
issue can result when using du g / tubing that has a very small diameter.
For additional assistance with troubleshooting or to order replacement parts, please contact
your local sales office or call 1-800-328-0787 for the manufacturer.
