PRE-OPERATING INSTRUCTIONS:
1. Inspect the unit for any visible damage that may have occurred during shipment. Report any
damage to the delivery carrier.
2. Remove the shipping crate, shipping straps and plastic wrap from unit. Discard skid and hardware.
3. Determine the location where the unit is to be installed. Be sure to allow sufficient access to the
unit for servicing and maintenance on all sides.
HANGING INSTRUCTIONS:
1. Remove the hanger kit from the owner’s manual envelope which contains four (4) threaded
eyebolts and hex nuts.
2. Thread a nut onto each eyebolt and thread an eyebolt into each of the four (4) threaded holes in
the cabinet. Tighten nuts against the cabinet. The unit is now ready to be hung in an appropriate
location.
NOTE: If hanging MX 3510 upside down is required, remove the four (4) 5/16” hex bolts from the
bottom of cabinet and relocate to top four corners. Then place the four (4) eye bolts into bottom
panel of cabinet.
3. Once eye bolts are secured, the MX 3510 is ready to be hung in an appropriate location. (See FIG.
1)
CAUTION: Use strong braided wire or chain to support the air cleaner. Hang from structural
supports.
NOTE: If a unit is to be installed on brackets against a wall, use brackets strong enough to hold the
unit. Install brackets securely onto the wall.
FIG. 1
NOTE: CHAIN LINK OR CABLE SHOULD HANG
VERTICALLY. MAXIMUM ANGLE OF 15º IS
RECOMMENDED FROM VERTICAL.
Eye Bolts & Hex
Nuts are supplied.

ELECTRICAL CONNECTIONS:
All electrical work must be done by a qualified electrician according to local, state and
national codes. Be sure that the designated circuit breaker is off until all wiring has been
completed.
NOTE: It is recommended that a properly sized motor starter and overload protector be used in the
supply circuit of the 3 Phase motor. The 120V units have thermally protected motors with on/off
switches.
1. Make electrical connections as shown in the wiring diagram to the wires protruding from the
conduit on the side of the unit.
2. Check blower for proper rotation direction. Blower should rotate clockwise when viewed from the
pulley end. If the blower rotates backwards, interchange two of the motor supply connections.
3. Check current draw of the motor. Do not exceed Amps specified.
PRE-OPERATING CHECKLIST:
Check blower drive belt for proper tension. Belt should deflect ¾” when firm pressure is applied
midway between the pulleys.
Check that motor, blower and drive pulleys are mounted securely.
Make sure that both corners of every pocket in the filter bag is supported by the filter support rods
and that filter support rods are fully engaged in their support brackets.
Air flow direction arrows on the pre-filters must point toward the blower.
Make sure all access panels removed during the installation are re-installed and the filter access
door is closed.
GENERAL MAINTENANCE:
Occasionally check the condition of the drive belt for tightness and wear.
Check the bower bearings for unusual wear and the blower wheel for debris and dirt. Clean when
necessary.
Check the wiring for loose connections or for cracked insulation.
No lubrication is required for the motor because it is a permanent pre-lube design. Excessive
dirt/oil should be periodically removed.
PRESSURE SWITCH ADJUSTMENT:
1. The pressure switch which turns the light on with a differential pressure increase, should be wired
to poles L1 (red) and L2 (blue) at the time of installation with 230/460 volt source (See Wiring
Diagram).
2. The pressure switch is preset at the factory to indicate (light on) dirty filters, but may need
readjustment due to a desire for earlier or later filter changes, a different combination of filters, or
because the set point shifted during shipping. The pressure switch is also orientation sensitive. To
re-adjust the switch, remove the hole plug in the side of the unit for access to the adjustment
screw. Make sure filters and pre-filters are installed in unit. Turn the unit on and place a piece of
cardboard over the intake covering about 80% to 85% of the intake area. With a standard

5
MX3510 MICRO AIR
screwdriver, turn the adjustment screw clockwise until the light goes off, or counterclockwise until
the light comes on.
3. For more time between filter changes (less air flow), cover slightly more of the opening, and for
less time between filter changes (more air flow), cover less of the opening.
AIR FLOW ADJUSTMENT:
Depending on the configuration, the MX3510 will be equipped with a variable diameter pulley on the
motor to allow the air flow to be adjusted to the installation requirements. The pulley is set for
maximum air flow from the factory. The air flow rate can be adjusted as follows:
1. Remove motor compartment access cover. Be careful to avoid tearing gasket material between
door and cabinet.
2. Remove belt.
3. Loosen pulley adjustment set screw on motor pulley and screw adjustable sheave out away from
fixed sheave. Tighten set screw onto flat of fixed screw (FIG. 1).
4. Adjusting the motor pulley may require a size larger or smaller belt, depending on the application.
5. Replace belt and check belt tension. Proper tension should be between 1/2” and 3/4” deflection
when belt is squeezed with normal pressure between fingers.
6. Replace motor compartment access cover.
7. Recheck for correct draw of motor amperage. NOTE: All filters and panels must be installed on
unit and door must be closed for current measurements of motor.

CHANGING FILTERS:
Always make sure that the unit is turned off before changing filters or servicing the unit.
1. The MX3510 is equipped with a filter change light or optional Magnehelic Gauge. If the differential
pressure has been set properly the light or gauge signals the need for examination for the filters.
2. When the light comes on, or gauge reads high differential pressure, turn the unit off and remove
the pre-filter only. Replace with a new pre-filter, making sure that the air flow directional arrow is
pointed toward the outlet end. Turn the unit back on. If the filter change light is off, or gauge reads
low differential pressure, then the unit is operating properly.
3. If the filter change light fails to go out, or the gauge continues to read high differential pressure
after replacing the pre-filter, then the media filter also needs to be replaced.
4. To install a new bag filter, turn the unit off. Remove the filter from the channel and insert a new
filter in place.
5. Start the unit. The filter change light should be off or gauge reads low differential pressure and the
unit should be operating properly.
INSTRUCTIONS FOR SIDE DISCHARGE BLOWER EXHAUST:
Read instructions completely before making changes. Due to relocation of internal
components, some wiring may be loose. Be sure to retain wires so they will not become
loose in air stream of blower inlet.
1. The MX3510 motor/blower module can be rotated so that the exhaust air exits from the side of the
unit. Before rotating the motor/blower module be sure that all input power is disconnected and the
unit is turned off.
2. Remove the motor access door and exhaust grille.
3. Remove 5/16” hex bolts and washers that secure the motor/blower module to the filter module.
4. Rotate the motor/blower module 90° as shown in FIG. 3.
5. Using 5/16” hex bolts and washers, re-secure the motor/blower module to the filter module.
6. Re-install motor access door and exhaust grille.
7. Reconnect input power and turn unit on. Check for proper air flow and blower rotation.

FILLING OF RCM MODULES:
1. Remove bulk charcoal or purasorb from the shipping container.
2. Set module on a level surface. Remove fill cover by removing six #10-32 Phillip head screws that
secure cover. Set cover aside (FIG. 6).
3. Open the lid of the charcoal or purasorb bucket. Pour the material from the plastic bag into the
module through the slots. It may be necessary to slightly shake the module to assure an even fill.
Excess material may be saved by resealing the bucket. Note that slow pouring will minimize dust
that will be present during filling.
4. After filling the module, discard the bucket and reinstall the fill cover removed in step 2.
5. With filter track in place and handle pulled out away from cabinet load RCM modules into track.
6. With filters in place rotate handle 90º and lock filter modules in place.
NOTE: The MX3510 requires two modules when used as a second main filter and four modules
when used as a first and second main filter.
