ELECTRICAL INSTALLATION:
IMPORTANT: The following installation instructions should be performed by a qualified
electrician. The following installation steps are for general use. Refer to Local and National
electrical codes for installations in your area.
WARNING: Installation can result in exposure to high voltage. Disconnect power source before
performing this installation. Proper lock out / tag out procedures should be used.
1. Unpack electrical box from skid. Inspect for any shipping damages.
2. The CAB unit can be operated with a factory assembled electrical control box, which contains a timer
circuit for automatic filter cleaning, a motor starter circuit for START/STOP operation and overload
protection for motor/blower(s) provided.
3. The electrical box is completely wired from the factory. Prior to making any electrical connections,
VERIFY PROPER INPUT VOLTAGE has been used for wiring the electrical circuit. IMPROPER
VOLTAGE MAY RESULT IN PERMANENT DAMAGE TO ELECTRICAL COMPONENTS.
4. Before making electrical connections, mount the electrical control box to a rigid permanent structure,
such as the unit, booth, or nearby wall.

5
CAB MICRO AIR
5. Electrical connections for motor/blower(s), Roto-Pulse solenoid valves, and incoming power shall be
required upon installation. The electrical box includes a safety interlock switch that disconnects power
to the circuit when the enclosure is opened. To gain access inside the electrical box, simply rotate the
disconnect switch towards the OFF position until a distinct click occurs. Using a Phillips screwdriver,
release the external hardware clamps located around the perimeter of the NEMA enclosure to allow
access to the electrical box.
IMPORTANT: Solid state circuits are sensitive to electrostatic shock. Take measures to ensure
that minimal static charge is discharged before making adjustments or changes to wire
connections on the timer board.
6. Route wire conduit from electrical box enclosure to solenoid valves housed inside NEMA enclosure(s)
located above the air inlet and Roto-Pulse valves of each clean air unit. Conduit should be sized to
allow the appropriate number of wires (16 AWG stranded) for all solenoids used. NOTE: A single wire
can be used for the COM output of the timer board to reduce overall number of wires.
7. Run wire conduit(s) from electrical box enclosure to each motor/blower. Wire size will vary based upon
input voltage and horsepower. A table is shown below for recommended wire size. Consult local
electrical codes.

8. In most instances, three phase motors supplied for the CAB are dual voltage motors. When making
electrical connections to the motor(s) make certain to check motor wiring for correct input voltage.
(Refer to motor wiring label located upon each motor casing.)
9. After completing installation of electrical conduit, run wire and make appropriate electrical connections
as noted on wiring diagram (see PAGES 14-21).
10. After wires have been routed and connected, run conduit and wire connections for input power.
Connect wires to the input side of the interlock disconnect switch located inside the electrical box
enclosure. Use grounding termination located near by the disconnect switch for supply ground.
NOTE: Wire size for supply connections shall be sized according to the maximum horsepower rating of
all motors connected to the electrical box. Total motor load shall not exceed 20HP max.
11. The electrical box enclosure is grounded to the grounding terminal connected to supply ground. When
making electrical connections to each unit motor/blower it is recommended to ground the units. This
can be accomplished by running a ground wire (of equivalent wire gauge) from the motor ground to the
electrical box enclosure.
12. Upon completion of all wiring connections, close the electrical box enclosure, securing each of the
clamps around the enclosure and then turning the disconnect switch to the ON position. The unit is now
electrically ready for operation. Connect power via circuit breaker and/or three-phase disconnect switch.
The unit can now be energized by pushing the START button. Be certain that all other installation steps
have occurred before starting unit.
13. Upon pushing the START button located on the hinged door of the electrical box enclosure, the CAB
unit blower should begin to run and auto cleaning cycle should begin (unless Photohelic switch is used,
See Photohelic Switch). To stop the unit from running, push the STOP button also located on the
electrical box cover. Note that after-pulse cleaning (off-line cleaning) cycle will begin and auto-cleaning
will continue for approximately 1 to 2 minutes.
NOTE: If the enable switch located on the timer board is in the disable position, off-line cleaning will not
occur. If off-line cleaning is desired, simply move the switch to the enable position.

CAB MICRO AIR
PHOTOHELIC SWITCH:
For applications that require a Photohelic switch to monitor filter loading and control the operation of
auto-cleaning, additional wiring must be performed.
1. An optional Photohelic switch is made available for the CAB unit. Additional electrical installation is
required for this option in order to allow the switch to control the automatic cleaning system while
monitoring the pressure drop across the cartridge filters. Before wiring may begin, first locate the
Photohelic switch kit and mount it to a suitable location. Run air lines from the Photohelic switch ports to
the CAB unit. (Refer to Photohelic switch installation instructions, Page 13).
2. Once the Photohelic switch has been physically installed, route electrical conduit from the electrical box
enclosure to the Photohelic switch.
3. Next, route 2 wires (16 AWG min.) from the Photohelic switch to the electrical box enclosure. Allow
adequate length of wire to reach the upper left corner of the timer circuit board terminal strip labeled
PRESSURE SWITCH (See PAGES 14-22 for Wiring Diagrams).
IMPORTANT: Solid state circuits are sensitive to electrostatic shock. Take measures to ensure
that minimal static charge is discharged before making adjustments or changes to wire
connections on the timer board.
4. Prior to making connections to the PRESSURE SWITCH terminal, disconnect the two wires connected
to the terminal and also disconnect the other ends of the red wires that are connected to an auxiliary
contact (switch) located on a motor starter relay. Discard wires for this installation.
5. Connect each wire from the Photohelic switch to each terminal on the timer board indicated as
PRESSURE SWITCH. Be certain that only one wire is connected to each terminal.
6. Move the enable/disable switch on the timer board to the DISABLE position. This will inactivate the off-
line cleaning feature of the timer circuit, which is more common when only demanding automatic
cleaning when filters reach a certain static pressure level.
7. After all wiring connections have been completed; close the electrical box enclosure, securing the
enclosure cover with screw clamps provided. By hand, turn the safety switch disconnect to the ON
position.
8. Photohelic settings are to be adjusted for optimized cleaning performance. Typically, a low setting at 2”
w.c. and a high setting at 3” or 4” is a recommended starting point. Once the pressure drop across the
cartridge filters reaches the upper limit of the gauge, the automatic cleaning system will engage and
continue to run until the static pressure drops below the lower setting.
NOTE: If the after-pulse (off-line pulse) switch is enabled, the cleaning system will continue to clean for
the duration of pulses upon reaching the lower limit setting noted above.
TIMER BOARD ONLY:
1. For applications that do not include a factory wired electrical box assembly (which includes timer, motor
starter(s), disconnect, etc.) a multi-channel timer PCB is supplied within a NEMA enclosure. Motor
starters and controls to start and stop the entire system are supplied by other means.
2. Before wiring, locate the timer board and enclosure in an appropriate mounting location that will allow
access for timer adjustments.
3. Run electrical conduit from solenoid valves located on the CAB unit(s) to the timer board enclosure.
4. Run wires from the timer board output channels to the solenoid valves (refer to Wiring Diagram,
PAGES 14-22).
IMPORTANT: Solid state circuits are sensitive to electrostatic shock. Take measures to ensure
that minimal static charge is discharged before making adjustments or changes to wire
connections on the timer board.

CAB MICRO AIR
5. Make electrical connects to the input of the timer board. NOTE: Timer board will operate at 108 -
132VAC, 50/60Hz.
CAUTION: Over voltage input (in excess of 132VAC) will damage the timer board and void
warranty. Internal fuse does not protect against over voltage conditions.
6. Make appropriate connections to the PRESSURE SWITCH terminals located on the upper left corner of
the timer board. If the terminal is permanently connected (with a jumper) the timer board will continue to
run as long as input voltage in present. Connecting a SPST pressure switch (or Photohelic Switch) to
this terminal is a recommended method.
CAUTION: Do not allow grounded connection to make contact with the PRESSURE SWITCH
terminal of the timer board. Contact with ground will result in permanent damage to the timer
board and void warranty.
UNIT OPERATION:
1. Turn the unit on via the start switch located on the front side of the electrical box.
NOTE: Some particulate may pass through the cartridge filters and blower upon initial start-up. This will
end once the filters have been seasoned and a powder cake has formed on the filter. If this condition
continues to occur refer to the section ROTO-PULSE CLEANING TIMER ADJUSTMENTS to increase
the period of time between pulses.
2. Once the unit is running, the Roto-Pulse cleaning system will be optional. Operation is detected by
hearing a .07 second air pulse approximately every 5 seconds. If adjustments to timing of pulses is
desired refer to section ROTO-PULSE CLEANING TIMER ADJUSTMENTS.
3. Check the After-Pulse Cleaning cycle by turning off the unit via the stop switch located on the front side
of the electrical box. The unit should continue to pulse every 5 seconds for a period of approximately 17
minutes. If adjustments to the after-pulse time is desired, refer to the section labeled AFTER-PULSE
CLEANING.

CARTRIDGE CLEANING OPERATION:
CAUTION: When servicing the collection system, be sure to turn the unit off.
The Micro-Air Dust Collector is designed with the Roto-Pulse Cleaning System to clean the cartridge
filters. This system provides superior cleaning performance using a rotating tube with pre-drilled holes
(See FIG. 5). As the diaphragm valve opens, the Roto-Pulse tube rotates while air exits the holes, thus
providing the cleaning of the cartridge.
FIG. 5
1. For proper cleaning, the compressed air pressure should be regulated at 80 psi maximum.
2. During normal operation the Roto-Pulse cleaning system is factory set to clean 2 cartridge filters for a
period of .07 seconds every 5 seconds
3. Once the unit is turned off, the cleaning cycle will continue for a period of 2 minutes. Do not service the
filters until cleaning is completed.
CAUTION: Allow 20 minutes downtime before accessing filters. After-pulse system is
momentarily operational after unit is turned off.
4. The Roto-Pulse cleaning operation dislodges particles from the cartridges. Particles then fall down into
the collection tray.
ROTO-PULSE CLEANING TIMER ADJUSTMENTS:
CAUTION: Installation can cause exposure to live components. Disconnect electrical power
before proceeding with timer adjustments. Proper lockout / tag out procedures should be used.
1. Turn unit off via the stop switch and disconnect power.
2. Open the electrical box cover.
3. The timer control board is present at the factory to clean 2 cartridge filters every 5 seconds. This time
can be adjusted from 1 second to 999 seconds. To adjust this time press the select button on the timer
board until the off time LED is lit. Press the up/down buttons until the desired value is displayed and
press select to set the new value.
NOTE: Cleaning of the filters too often will decrease your level of performance. A certain level of dust
cake on the filters will improve the efficiency of the filter cartridges. You should try to maintain 1” W.C. of
pressure differential across the filters the time between cleaning pulses should be increased until this
can be achieved.
4. The timer control board is preset at the factory to have a cleaning pulse duration of .07 seconds. This
can be adjusted from .05 seconds to 600 seconds. To adjust this time press the select button on the

9
CAB MICRO AIR
timer board until the on time LED is lit. Press the up/down buttons until the desired value is displayed;
press select to set the new value.
NOTE: While this time can be adjusted we recommend you leave the “ON TIME” at the factory setting. If
less cleaning is needed you should increase the time between pulses as this means of reducing the
amount of cleaning. If more cleaning is needed you should decrease the amount of time between pulses.
Be aware, as the time between pulses is decreased for additional cleaning, this will increase your
compressed air consumption and create an additional load on your compressed air system.
5. Once adjustments have been made replace the electrical box cover and reconnect the power.
6. Start the unit and observe the new pulse settings and determine if additional adjustments are
necessary. If more adjustments are needed repeat the previous steps.
AFTER-PULSE CLEANING TIMER ADJUSTMENTS:
CAUTION: Installation can cause exposure to live components. Disconnect electrical power
before proceeding with timer adjustments. Proper lockout / tag out procedures should be used.
1. The unit is equipped with an After-Pulse Cleaning cycle. This cycle will continue to clean the cartridge
filters for a period of time after the unit is turned off.
2. The length of the After-Pulse operation is present at the factory for 100 seconds. This time can be
adjusted from 0 seconds to 999 seconds. To adjust this time press the select button until the off-time
LED is lit. Press and hold the select button for 3 seconds. Press the up/down buttons until the desired
value is displayed; press select to set the new value. The after-pulse operation can be disabled by
setting the time value to zero (0) seconds.
