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 ” and ” deection when belt is squeezed
with normal pressure between ngers.
6. Replace motor compartment access cover. Recheck for
correct current draw of motor.
CHANGING FILTERS
!
CAUTION: Always make sure that the unit is turned off
before changing lters or servicing the unit.
1. The MX3510 is equipped with a lter change light or
optional Magnehelic Gauge. If the differential pressure
has been set properly, the light or gauge signals the need
for examination of the lters.
2. When the light comes on, or gauge reads high differential
pressure, turn the unit off and remove the pre-lter only.
Replace with a new pre-lter, making sure that the air ow
directional arrow is pointed toward the outlet end. Turn the
unit back on. If the lter change light is off, or gauge reads
low differential pressure, then the unit is operating properly.
3. If the lter change light fails to go out, or the gauge
continues to read high differential pressure after replacing
the pre-lter, then the media lter also needs to be
replaced.
4. To install a new bag lter, turn the unit off. Remove the lter
from the channel and insert a new lter.
5. Start the unit. The lter change light should be off, or gauge
reads low differential pressure and the unit operating
properly.
INSTRUCTIONS FOR SIDE DISCHARGE BLOWER
EXHAUST ON MX 3510
!
CAUTION: Read instructions completely before
making changes.
1. The MX3510 moto/blower module can be rotated so that
exhaust air exits from the side of the unit. Before rotating
motor/blower module be sure that all input power is
disconnected and unit is turned off.
2. Remove motor access door and exhaust grille.
NOTE: Care is required when removing the panel to protect the
blower outlet gasket.
3. Remove
15
⁄
16
” hex bolts and washers that secure motor/
blower module to lter module.
4. Rotate motor/blower module 90° as shown in FIG. 3.
5. Using
15
⁄
16
” hex bolts and washers re-secure motor/blower
module with lter module.
!
CAUTION: 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.
6. Reinstall motor access door and exhaust grille.
NOTE: Care is required to protect blower outlet gasket.
7. Reconnect input power and turn unit on. Check for proper
air ow and blower rotations
PRESSURE SWITCH ADJUSTMENT INSTRUCTIONS
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 208/230/
460 volt source. (See Wiring Diagram.)
2. The pressure switch is preset at the factory to indicate (light
on) dirty lters, but may need readjustment due to a desire
for earlier or later lter changes, a different combination
of lters, or because the set point shifted during shipping.
The pressure switch is also orientation sensitive. To
readjust the switch, remove the hole plug in the side of the
unit for access to the adjustment screw. Make sure lters
and pre-lters 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 screwdriver,
turn the adjustment screw clockwise until the light goes off,
or counterclockwise until the light comes on.
3. For more time between lter changes (less air ow), cover
slightly more of the opening, and for less time between lter
changes (more air ow), cover less of the opening.
GENERAL MAINTENANCE
1. Occasionally check the condition of the drive belt for
tightness and wear.
2. Check the blower bearings for unusual war and the blower
wheel for debris and dirt. Clean when necessary.
3. Check the wiring for loose connections or cracked
insulation.
4. No lubrication is required for the motor because it is a
permanent pre-lube design. Excessive dirt and or oil
should be removed periodically.
