Industravac vacuum producers are designed for operation at or
near sea level atmospheric pressure and a nominal ambient
temperature of 70°F (21°C).When necessary, they can be factory-
designed for higher altitude or higher temperature operation.
Note: V Series stationary models should be properly protected
from precipitation.
Portable Model. The portable Industravac unit is designed for
use on flat, dry, level surfaces. As a safety precaution, the
wheels should be blocked to prevent accidental movement.
Consideration should be given to the noise generated by
Industravac equipment and its contribution to the ambient
noise level. When desired, the exhaust can be fitted with an

inadvertently, and check that the dirt can gasket is in place
beneath the separator. Raise the dirt can, making sure it
seals tightly against the gasket. Inspect both separator inlet
ports to be sure they are clear.
Stationary Model. No special foundation is required. A level
concrete floor or pad is recommended, although any other
substantial floor is satisfactory. The Industravac base should
be placed on rubber isomode pads furnished with the unit.
If optional dirt can liners will be used, install one liner in the
dirt can and make sure the equalizing line is in place, properly
connected to the separator and dirt can.
In selecting an installation site for a stationary Industravac
model, be sure the unit is readily accessible for servicing by
allowing several feet of clearance around the machine. The
exhaust should discharge outdoors or into a room having
ample volume and sufficient ventilation to allow air to escape.
Avoid placing the Industravac unit in an enclosed room where
a substantial heat buildup might occur. The ambient temper-
ature should not exceed 104°F (40°C).
CAUTION: The dirt can liner must not be used without
the equalizing line (the liner will be sucked out of the
can, up against the filter bags) and vice versa (without
the liner in place, mechanical and environmental damage
may result)
Unpacking
CAUTION: If the separator is equipped with an optional
explosion relief port, it must be installed in accordance
with the National Fire Code and all applicable safety
regulations. The port should be positioned away from
nearby personnel and ducted to the outdoors.
1. Uncrate the Industravac unit, saving all literature, boxes
and parts.
NOTE: The D Series Industravac is shipped on two skids:
the frame with vacuum producer on one skid, and the
separator horizontally mounted on the other skid. To
assemble the two units, attach the rubber inlet sleeve to
the vacuum producer inlet; lift the separator at the lifting
points, position it on the frame and align the rubber
sleeve and bolt holes. Secure with bolts provided.
2. Remove packing materials, plugs, etc.
3. Electrical.
NOTE: All wiring and electrical adjustments or installations
should be done by a qualified electrician in accordance with
the National Electrical Code and local codes.
The standard electrical motor furnished with the A, B and D
Series Industravac vacuum producer is a NEMA design B,
open drip proof induction type motor suitable for 60 Hz, 3-
phase, 200-230/460VAC operation. The C Series and V
Series have a TEFC type motor as standard. Other motors
such as TEFC and explosion-proof types, and other volt-
ages, may be furnished as required by the application.
3. Use the packing slip to check off and confirm the pres-
ence of all ordered components.
4. Lower the dirt can by raising the bail arm in front of the
separator and look inside for parts and optional accessories
(e.g., equalizing line, dirt can bags, motor starter, hose,
tools) which are often shipped loose in this location.
5. Read all instructional and warning labels on the machine
before operation.
CAUTION: The electrical service at the installation site
must supply the voltage stamped on the motor name-
plate. Operation at an incorrect voltage will result in a
damaged motor.
Industravac Setup
1. Vacuum producer. The upblast exhaust tubing on A, B
and D Series units will accept, if required, an air gate (throt-
tling valve), discharge silencer, tubing connection and
weather cap. The C Series has a bottom exhaust with
silencer, Patent No. 4,874,410, as standard equipment.
(Optional adapter P/N PLT90023 can be purchased to pro-
vide a 6" O.D. tube connection.) The V Series equipped with
exhaust diffuser for
weather protection
and a relief valve for
load control. If any
optional items have
been purchased for
field installation, they
should be mounted
Industravac portable units are furnished with a starter and
50-ft cable, requiring only a suitable male plug for connec-
tion. In making the electrical connections for a stationary
Industravac, follow the wiring instructions furnished. All
wiring, power cords and circuit breakers should be of ample
capacity to ensure that proper voltage is maintained at the
motor terminals while starting and running. Starters should
have thermal overload protection and low-voltage protection.

on the exhaust tubing with the air gate first, followed by a
flexible connector (see diagram and caution below), silencer
and weather cap or tubing.
A grounding lug is provided for those Industravac units having
optional grounded filter bags. In order to effectively bleed off
static electricity charges, this lug should be securely connected
to an electrical ground.
CAUTION: Tubing connected to the vacuum producer
should be properly aligned and supported so there is no
stress on the machine casing. The tubing must not
touch the vacuum producer. Use a flexible connector to
create an isolating gap of approximately 1" minimum
and clamp it in place for an air-tight seal.
4. Motor Rotation. Perform a pre-start check to make sure
the motor turns in the correct direction. (While the vacuum
producer will operate both ways, its performance will be
greatly diminished if it runs backward.) If V Series rotation is
incorrect, it will perform as a blower, not a vacuum producer.
2. Separator. Open the separator access door to confirm
that the door gasket and filter bags are in place and secure.
With the door open, operate the external bag shaker to
check for proper action.
A rotation direction arrow is located on the vacuum producer
casing. To see if the motor is wired correctly, momentarily
start the motor. "Bump" or jog the start button and observe
the direction of rotation at either the end bell of the motor or
the motor shaft, whichever is visible. If the rotation is incor-
rect, the motor wiring must be reversed.
Lower the dirt can to see that nothing has been left inside

IV. Operation and Adjustments
NOTE: An Industravac vacuum cleaning system consists of
the Industravac unit and its associated components. The
vacuum producer is designed for operation under load,
hence it must always be connected directly to hose and
tools or to a tubing system with hose and tools.
4. Check the tubing system and vacuum equipment for
leaks. At the separator, check the access door, dirt can
seal and hose inlet valves. Examine all hoses, tubes,
and fittings connected to the Industravac unit. Air leaks
are highly detrimental to the overall system perfor-
mance, wasting power and impairing the operating
efficiency.
Machine startup
1. Turn the Industravac unit on, having fully completed the
previous setup procedures.
CAUTION: When the vacuum producer is operating, its
housing will be hot to the touch. Use caution when
making inspections or adjustments in this area.
2. (For units equipped with discharge air gate.) With a full
vacuum system load connected to the separator inlet(s),
connect an ammeter to the motor circuit. Measure the
draw (amperage) of the motor. If it is below the full load
current rating, open the air gate until the amperage reach-
es, but does not exceed, the full-rated motor capacity.
The air gate should then be fixed to prevent opening
beyond this point.
Hose and tools
For optimum performance, Industravac units should be used
only with complementary Spencer vacuum cleaning equip-
ment system components—Spencer tubing, fittings, flexible
hose, tools, attachments and accessories. These products
have been designed and sized specifically for compatible
use in an Industravac system.
3. (For units equipped with Electronic Modulating Bleed
Control.) Follow adjustment instructions in the separate
data sheet accompanying the EMBC.

If operating problems are detected, notify your local Spencer
Representative, describing the situation in detail before
attempting repairs or disassembly.
NOTE: For maintenance of the Vortex regenerative vacuum
producer, equipped on Series V models, see handling,
installing and operating instructions Form ZZ.
The Industravac vacuum producer has an overhung type
construction with multiple impellers mounted directly on the
motor shaft. The motor bearings support the shaft and
impeller assembly.
NOTE: For maintenance of the motor, consult motor manu-
facturer's information provided with the equipment.
NOTE: Disassembly, repair or alteration cannot be done by
unauthorized personnel during the warranty period without
voiding the warranty. The maintenance instructions that follow
are provided as a customer service to facilitate field repair
after the warranty period.
Six impellers and five deflectors are shown in the accom-
panying diagram of a typical vacuum producer; the actual
number of each will vary from two to nine, depending on
the model.

Disassembly (For Series V see Form ZZ)
Reassembly (For Series V see Form ZZ)
NOTE: Read these procedures carefully before attempting
disassembly. Refer to the diagram on page 7 and the
instructions below as you proceed. Contact your local
Spencer Representative for help if any questions arise.
1. Bolt the motor down tightly in its original position with the
shaft in the exact center of the vacuum producer casing.
Be sure that shims (if removed) are replaced in their
exact positions on the same attach-points as before. See
that packing #3 is in place and tight around the shaft.
To facilitate repairs, disconnect the vacuum producer from
the separator and unbolt the casing from the Industravac
frame. Using adequate and safe lifting equipment, remove
the vacuum producer to a convenient work location.
2. Place the last-removed impeller #9 on the shaft and push it
toward the motor until it bottoms. Position the impeller same
distance from the division head as noted during disassembly
and tighten. Rotate once by hand to check placement.
CAUTION: During reassembly, parts must be installed in
exactly the same relative positions. Therefore, as each
part is removed, it should be marked or tagged and
stacked in sequence. It is especially important that the
location of each impeller, as well as its rotated position
on the shaft, be marked.
3. Place the last-removed deflector #8 back tightly against
the stops and, with a suitable tool, caulk the rope packing
#5 firmly into the groove.
4. Place the next impeller on the shaft. Push it toward the motor
until it bottoms. Back it off approximately 1/8" and tighten it to
the shaft. Rotate once by hand to check placement.
1. Begin at the intake and remove, in turn, end head #7,
(some models may have an extra spacer and half deflector
inserted during manufacturing; these must be removed
before reaching the first impeller), impeller #9A, spacer
#12, rope packing #5, deflector #8A, impeller #9B, and so
on until all impellers have been removed. (Note: division
head #4 cannot be removed.)
5. Place spacer #12 into the last deflector. Place the next
deflector into position in the casing as shown, caulking
the rope packing into the groove.
Note: Make sure the spacer and deflector are pressed
back tightly and at a uniform distance from the end of the
casing at all points.
2. Check the division head packing #3 and replace it if dam-
aged. Any time the motor is removed and reinstalled,
replace this packing before the motor is put in place.
6. Repeat procedure until all stages are reassembled.
7. Align gasket #11 and division end head #7 together and
bolt to casing.
3. Temporarily reconnect electrical power and run motor to
check for mechanical or electrical defects. If the motor
must be removed, disconnect electrical power, remove
bolts #15 and slide motor straight back, being careful not
to damage packing #3 around shaft or the shims (if pre-
sent) under each motor attach-point.

Balancing (For Series V see Form ZZ)
Changing Filter Bags
Keep a set of spare filter bags in reserve at all times.
Examine the bags in service periodically and replace them
with genuine Spencer filter bags when visibly worn. Also
look for leaks, which are signalled by dirt on the outside of
the bags or on the bag head or by dust in the discharge
airstream.
Turn the machine on with inlet blocked to check balance. If
there is excess vibration due to an unbalanced condition
after reassemble, use the following balancing procedure:
1. Mark the position of the end impeller hub on the shaft.
2. Loosen the bolts or screws holding the impeller on the shaft.
3. Rotate the impeller 90° on the shaft, retighten the bolts or
screws.
4. Run the machine again at operating speed and check
vibration.
5. Repeat this procedure until the best balance (least
vibration) is obtained. If satisfactory results are not
achieved, contact the Spencer Service Department for
recommendations.
3. Separator
Shaking the Filter Bags
NOTE: The vacuum producer must be turned off during bag
shaking, or loosened dirt will immediately redeposit on the
filter bags.
1. To install a new filter bag, compress the spring collar at
the bottom of the bag.
Grasp the external bag shaker handle and move it back and
forth vigorously for 5 to 10 seconds. This action loosens dirt
that has accumulated inside the filter bags, allowing it to fall
into the dirt can.
2. Insert the compressed spring collar into the bag head
opening and allow it to resume its original shape.
For portable Industravac models, bag shaking should be
done after each use; for stationary models, after each shift
to maintain optimum vacuum performance.
Emptying the Dirt Can
For new Industravac applications, check the rate of dirt accu-
mulation in the dirt can and then establish a regular emptying
schedule. If the application characteristics change, modify the
schedule to suit. The can should be emptied when it is no
more than 3/4 full. Or, for convenience, it can be emptied by
weight rather than volume, at any lesser level.
To remove the dirt can, lift the bail arm in front of the separator,
lowering the container onto the floor where it can be wheeled
away on its casters for emptying. To replace the can, simply
push it into place under the separator. A self-locating guide
positions the can correctly. Lower the bail arm, lifting the can
into position and sealing it against the rubber gasket.
3. Pull up on the bag to be sure it is properly seated. The
recess in the spring collar must be at the bag head opening.
(Entire collar should not be below bag head.)
4. Install buckle on the narrow tab of filter bag and attach to
hook on shaker plate. Pull on tab end to remove slack.
In addition to standard cotton sateen filter fabric, various
other materials are available in Spencer replacement bags.
They offer specialized properties suited to adverse condi-
tions such as dampness, abrasion or chemical attack.
Changing Door and Dirt Can Gaskets
1. Peel off old gasket.
2. Clean old adhesive off gasket seat.
Special-purpose filters are also available, such as optional
HEPA (High Efficiency Particulate Air) filters with a filtration
efficiency of 99.97% at 0.3 micron particle size. For recom-
mendations, consult your Spencer Representative.
3. Check replacement gasket for fit; trim if necessary.
4. Coat gasket and seat with rubber cement, apply gasket.
5. Check for airtight seal after cement is dry.
Maintaining the Equalizing Line
Periodically check the equalizing line, if present, to be sure it
is clear and free of leaks, If problems occur, replacement
kits are available from Spencer.
NOTE: Spencer disposable dirt can liners must always be
used if an equalizing line has been installed or mechanical
and environmental damage will result.

Replacing the Target Plate
5. Replacement Parts
The target plate, Patent No. 4,874,410, at the bottom of the
separator is able to absorb a great deal of impact and
abrasion damage as it diverts solid litter into the dirt can.
Because it will eventually wear out, provisions have been
made for easy replacement:
Provide full information about your Industravac equipment,
including the serial number and catalog number, when
ordering parts. When ordering replacement filter bags, be
sure to provide the bag part number. Replacement bags are
supplied in the following quantities: A Series–10 bags, B
Series–19, C Series–12, D Series–24, and V Series–10. For
other vacuum producer and separator parts, refer to the
illustrations on pages 5, 6, and 7 for the names of needed
items. Touch-up paint is also available from Spencer.
1. Lower the dirt can and wheel it out of the way.
2. Swing the target plate to a horizontal position and release
it from its supporting hooks.
3. Reverse the procedure in Step 2 to install a new plate.
4. Machine Exterior
The nature of its work exposes the Industravac unit to dust
and dirt which should be periodically removed by washing
the exterior with soap and water. Disconnect the electrical
power before any cleaning procedure; do not spray water
directly on the motor, electrical connections or in the vacuum
producer outlet.
