THEORY OF OPERATION
This unit is a wall mounted air cleaner employing a high performance blower producing very high velocity airflow through
the arm removing harmful smoke from an operators breathing zone. The air exits the motor and travels through a hose
into a filter box. Fine solid particulate and smoke is removed from the air as it is pushed through a series of filters.
An initial 2 inch aluminum pre-filter collects large particles and potential sparks before they reach a 2 inch pleated
pre-filter. These relatively inexpensive pre-filters prevent the more expensive main filter from becoming quickly clogged.
The pre-filters may be changed several times before the main filter needs to be changed.
Upon leaving the pre-filters, the air passes through the main filter, which removes even smaller particulate. The clean air
then goes back into the atmosphere.
All factory furnished filters have a U.L. class II rating and using any filters other than those specified for this unit
is not recommended.
Use of any product other than that recommended by the manufacturer will void the warranty.
The main (or final) filter may be selected from three (3) grades available, depending upon the level of performance
desired. All of these are high efficiency multi-flow filters which feature extended surface area for long life in high velocity
filtration systems.
Selection of the filter best suited for the job should be discussed with a dealer or a factory representative
UNPACKING
Carefully inspect the unit for concealed damage that may have occurred during shipping and handling. If any damage is
found, immediately contact the freight company. Make sure that there are no dents in the housing, as they will prevent
the filters from sliding into the units smoothly.
Blower Maintenance:
BEFORE ANY MAINTENACE OR SERVICE IS PERFORMED, BE SURE THE UNIT IS DISCONNECTED FROM THE
POWER SOURCE TO PREVENT ACCIDENTAL STARTING.
Periodic cleaning is necessary for blower housings and fan wheels constructed of steel. Carefully clean fan wheels with a
wire brush. Failure to clean fan wheel could result in an imbalance and cause premature failure of the unit.
Blower housings and fan wheels constructed of aluminum are maintenance free.
Motor Maintenance:
BEFORE ANY MAINTENACE OR SERVICE IS PERFORMED, BE SURE THE UNIT IS DISCONNECTED FROM THE
POWER SOURCE TO PREVENT ACCIDENTAL STARTING.
Blow off the motor using low pressure air to remove dust and dirt. Air pressure above 35 PSI should not be used. High
pressure may cause damage to insulation. Excess dust may cause excessive temperature.
Lubrication:
Lubrication of the motor should be done periodically as specified by the motor manufacture. If the motor run in continuous
high ambient temperatures, in dirty or moist locations, subject to high vibrations or where the shaft end is hot, the motor
should be lubricated every 6 months.
Contact Baldor Motors (www.baldor.com) for more complete maintenance and service instructions.

General Assembly
ARM
BLOWER
DUCT
FILTER BOX
The general order of the parts for 73-501 is an arm connected to a blower, and then the blower connected to the filter box,
as shown in the figure above.
Duct work will always be required when connecting the blower to the filter box.
Depending on the arm used, duct work may or may not be needed.
The filter box has internal mounting brackets. This allows the filter box to be mounted to a wall or support structure.
The blower is mounted to a bracket. The bracket is supplied with the blower. This bracket can into be mounted to a wall
or support structure.
Mounting the arm to the blower depends on what arm is being used. Select arms include a ‘direct-mount’ bracket that will
allow the user to mount the arm directly to the blower. Other arms will require connecting flanges and duct work. Please
see next section for detailed information on the arm being used.
Ace Industrial recommends spiral duct work for ducting between the blower and the filter box. Flex tubing may be used
for ducting between the arm and the blower.

the arm will develop stress on the support structure when the user pulls and positions the arm during use.
2. Using the mounting bracket, position the bracket on the support structure and, using a level, mark the holes in
preparation for attaching the bracket. Be sure the bracket is as square and as level as you can make it. Use the level
for this. Now mount the bracket and be sure it is secure.
3. Slide the hose away from the white base bracket. Please note that there is a bolt with a red painted head. This bolt is
in a hole marked 2. Remove this bolt and pivot the white bracket 90 degrees so the hole marked 1will line up with the
hole in the bracket. Replace the red bolt and nut and bring to a snug fit. (See figure 2.)
4. Attach the 90 degree elbow to the white arm bracket. Note that the elbow and the white bracket have a small mating
flange. There is a rubber gasket that seals the flanges of the elbow and the white bracket. Install the steel metal
clamp over the rubber gasket and flanges. BE SURE THAT THE ELBOW AND ARM ARE IN A PERFECT
VERTICAL POSITION BEFORE TIGHTENING THE CLAMP. The arm should be vertical and the elbow is also
vertical (See Figure 2).
5. With assistance, mount the assembled arm and elbow to the mounting bracket. The elbow has a mounted 8 hole
black nylon swivel collar. Locate and bolt the arm, elbow, and black nylon collar to the bracket by the 8 holes.
Tighten the bolts to hold the elbow to the mounting bracket. DO NOT OVER TIGHTEN THE BOLTS. Be sure the
elbow can swivel freely at the bracket.
6. The arm will need final adjustment/tuning for easiest movement and to stay in place upon positioning. You will find
friction pads and adjustment pivot joints in four (4) places, 1) Pivot point at the white bracket, 2) Pivot point at the
center of the arm. 3 & 4) Pivot points at the hood location. Only
put enough tension on these pivot joints to hold the arm in any
position it is placed. The arm final adjustment is key to the arm
being user friendly. DO NOT OVER TIGHTEN THE PIVOT JOINT
FRICTION DISKS. Depending on arm usage and movement,
occasional adjustments may be required. Based on the arms
application, cleaning of the internal support structure may require

the support structure is designed to withstand the stress and strain that the boom/arm may develop under use.
THE FACTORY IS NOT RESPONSIBLE FOR ANY FAILURES OR DAMAGE CAUSED TO THE BOOM OR TO THE
BUILDING STRUCTURE DUE TO INSTALLATION NEGLIGENCE.
2. Take the mounting plate and remove the steel pivot rod by removing the small bolt and nut on the bottom of the
rod. Please note that the mounting plate has a brown friction pad. This pad will assist you in telling top from
bottom of the mounting plate. The friction pad and rod with bolt is the bottom of the bracket. Be sure to mount
bracket as such. See figure 6.
3. Using a level, mount the bracket. Once you have mounted
the bracket, recheck for squareness and strength. BE
SURE THE BRACKET IS PERFECTLY VERTICAL.
4. Mount the first half of the boom arm with the groove on the
bottom to the wall bracket. You should have noticed a flat
and a thick steel thrust washer on the steel pivot rod when
you removed the rod from the wall bracket. Be sure these
thrust washers are installed on the underside of the boom.
See figure 6. Slide pivot rod into the top of the mounting
bracket and into the bearing on the boom and through the
thrust washers and into the bottom of the mounting
bracket. The rod has flat sides and the mounting bracket
has matching flat sides. Be sure the rod slips completely
into the flat sides. Install the small bolts and nuts and
tighten snugly.
5. Install the second half of the boom arm to the first half and use the 4 large bolts,
tooth washers, and nuts. Tighten the bolts firmly.

ASSEMBLY
The tools necessary to complete assembly of the blower-exhauster are a screwdriver and a wrench. If your unit
requires wiring, wire the motor according to the following directions.
WIRING
1. Have a qualified electrician wire the motor following the wiring diagram located on the motor nameplate for
high or low voltage as needed. Check nameplate for electric characteristics to connect motor to an identical
power outlet. (NOTE: Wiring directions do not guarantee proper rotation.)
CAUTION: PROPER ROTATION IS ESSENTIAL TO ACHIEVE OPTIMUM CFM DELIVERY.
2. Before starting the unit, check the blower wheel to see that it is rotating freely and that there are no
obstructions or loose material present. If the unit has been in storage or subject to adverse moisture
conditions, it is advisable to make sure the motor is dry before starting the unit.
CAUTION: BEFORE ELECTRICIAN LEAVES, VISUALLY CHECK ROTATION OF THE FAN WHEEL.
3. To check for proper rotation, turn the power ON and OFF quickly. As the blower is slowing down, check to
see that the fan wheel is rotating in the same direction as the directional arrow located on the motor. If the
fan is not turning in the direction of the rotation arrow, the unit is wired in reverse. There will be very little
suction or air movement if wired in reverse. If the unit is wired correctly, the wheel should turn clockwise or
toward the viewer. The proper rotation will increase the amount of suction by almost 50%.
4. If the motor top is not vented (as with explosion proof motors) and view is obstructed, observe the blower
wheel rotation by looking into the exhaust duct. The wheel should turn clockwise or toward the viewer if the
unit is correctly wired.
CAUTION: DO NOT LOOK DIRECTLY INTO THE MOTOR COMPARTMENT OR OUTLET WITH THE POWER ON
OR WITHOUT WEARING SAFETY GOGGLES.

12
TROUBLESHOOTING
Motor does not start or runs very slowly
Check the wiring. Check all wire connections. After rechecking and the motor still does not start or runs slowly, there
is an internal motor problem and must be handled by an authorized Baldor Service Center.
Unusual Noise
Check the cooling fan on the top of the motor for damage. The fan must be replaced if damaged. Contact your
supplier for more information.
Check to see that the wheel turns freely. With the unit disconnected from the electrical supply, rotate the wheel by
hand. If the wheel is not turning freely, the wheel has slipped on the motor shaft. Determine if the wheel has slipped
toward the motor or away from the motor. Through the intake opening, slightly loosen the 2 set screws. Put thread
lock on the exposed threads of the screws. Move the wheel so that the motor side of the wheel is ¼” from the
housing. Tighten the screws and energize the motor.
If the noise is still present, contact a Baldor Service Center or www.baldor.com.
Smoke
Check the voltage to make sure the unit voltage and the source voltage are the same. Contact a Baldor Service
Center if damage has occurred to the unit.
Little suction or air movement immediately after start-up
Check for any obstructions in the inlet and the outlet of the blower.
Recheck wiring and wire connections. Reverse the wiring could cause the wheel to spin in the wrong direction. If
problem persist, contact a Baldor Service Center or www.baldor.com.
Reduced suction after running for a period of time
Check for any obstructions in the inlet or outlet. Remove obstructions
Check if intake hose or duct is kinked, crushed, or clogged
Check to be sure there is enough make up air. If not, open an outside window.
Not enough suction to exhaust pollutant
Check the nozzle positioning. For most efficient pickup, the nozzle should be 1 duct diameter or less from the source
of pollutant, and no more than 2 duct diameters away.
Check the length of the duct or hose and the number of bends in such. Excess length and/or bends will result in poor
pick-up. Contact your distributor for assistance.
Check the number of drops from the unit. Too many drops will cause poor pick-up. Contact your distributor for
assistance.
