Installation
Receiving:
Before removing any packing, visually inspect the exterior
of the shipment for any sign of damage. Should there be
any damage, bring it to the attention of the delivering UPS
or truck line and note the same on the receiving ticket.
Should there be damage you must place a claim with the
truck line. They are the only ones who will pay for the
damage done and you are the only one who can place that
claim.
Mounting:
Ensure the unit is securely bolted to your floor and is level,
square, and plumb. Leave space around the unit for
cleaning, inspection and maintenance.
Pre-Start Up Check List:
1. Are all mounting bolts tight?
2. Is disperser blade mounting bolt tight?
3. Has electric motor been wired according to the diagram
on the motor label? Is motor grounded?
4. Does motor have emergency stop located as per local
code?
5. Bump motor and check rotation, looking down into the
container, shaft should rotate clock-wise. If direction is
incorrect reverse motor as explained on the motor label.
Safety
Please follow the below safety precautions. Read this
complete manual before trying to operate your mixer.
Failure to follow these instructions could result in serious
bodily injury or death.
• Never move the unit without a suitable lifting device.
• Have a qualified individual bring power to your unit.
• Always ground the unit.
• Never run the unit in open air.
• Never adjust the speed without the unit running.
• Always lockout the power when working on the unit.
• Always use the container holder to restrain the container
during operation.
Electric Motor Safety:
Motors should be installed, protected and fused in
accordance with latest issue of National Electrical Code,
NEMA Standard Publication No. MG 2 and local codes.
Eyebolts or lifting lugs are intended for lifting the motor
only. These lifting provisions should never be used when
lifting or handling the motor with other equipment (i.e.
gearboxes or other driven equipment) as a single unit. Be
sure eyebolt is fully threaded and tight in its mounting hole.
Eyebolt lifting capacity rating is based on a lifting alignment
coincident with the eyebolt center-line.
Eyebolt capacity decreases as deviation from this alignment
increases. See NEMA MG 2.
Frames and accessories of motors should be grounded in
accordance with National Electrical Code (NEC) Article 430.
For general information on grounding refer to NEC Article
250.
Rotating parts such as pulleys, couplings, external fans,
unusual shaft extensions should be permanently guarded.
Keep hands and clothing away from moving parts. Trained,
qualified personnel should make electrical repairs only.
Mechanical Variable Speed Drive Safety:
When maintenance is required in the area of the equipment
necessitating removal of the guarding, the prime mover
should be turned off and “locked out”.
The user of variable speed belt drives should be aware of
the hazards through misuse of the product or failure to
protect against contact with moving parts.
Spring-loaded pulleys should never be disassembled without
first receiving instruction from factory.
Rapid acceleration or braking, or shock loading may cause
a shaft to fracture due to torsional twist beyond its capacity.
All mounting screws on the pulleys must be kept tight.
Even though each pulley is individually balanced at the
factory the system in which the pulleys operate may
resonate, particularly at high RPM’s over 1800. Sometimes
a new belt will reduce vibration levels in a system.

INDCO, Inc. M-M-30118 mixer manual HS-5 date: 3/8/05
CAUTION:
• Never run mixer without an impeller.
• Never run the impeller in open air.
• Never run impeller outside a container.
Dispersion “rules of thumb” include:
10-HP is required for every 100-gallons, under 20,000-cPs.
Single shaft dispersers are not recommended for product
over 50,000-cPs. The liquid level should equal the liquid
diameter. In general the disperser is run at blade tip speeds
of 4,000 to 6,000 Feet-Per-Minute. FPM = rpm x 0.262 x
blade diameter, in inches. The lower ranges are used for
agitation or blending operations while the upper ranges are
used for dispersions of difficult materials. The middle range
is adaptable to a great many solutions and easier
dispersions. Experience by the operator will be the best
key as to what speed to try first on materials handled at
your facility.
The blade should equal 1/3rd the tank diameter and be
center, vertical mounted. Under normal operation the blade
is located from 1 to 1.5 blade diameters from the bottom.
If this results in an excessive vortex, the blade may be
lowered. If the action is a little slow at the above location,
the blade may be raised to a limit of 2.5 diameters to obtain
a good flow providing the amount of material over the blade
is greater than the amount of material beneath. At this
point, good action is usually assured in the bottom of the
container.
When adding materials to the container for a test, always
introduce the liquid phase first. In most cases, the disperser
should be started and solid phase added. However, on
some formulations such as enamel, particularly those of
colored pigments, it has been found most satisfactory to
add vehicle in tank and then add all pigments before turning
on motor.
Air Cylinder Operation:
Before connecting your air supply ensure the lift control
valve is in the center (off) position. The valve lever is spring
loaded to rest in the center position. Connect your air supply
to the quick connector on the 3-position control valve.
Maximum air pressure is 100 PSI. Note that air pressure is
used to both raise and lower the cylinder. The following will
enable you to adjust the height of the impeller or to install
and remove your batch container:
CAUTION: After the air line is installed and before operating
the machine for the first time, move the lift control valve to
the downward position. This will charge the air cylinder
and prevent surging when the lift control valve is moved to
the upward position.
• Lifting:
Move the lift control valve to the up most position. To
stop upward motion move valve to center (off) position.
• Hold:
To hold the impeller at any height move the lift control
valve to the center (off) position.
• Lowering:
Move the lift control valve to the down most position.
To stop downward motion move valve to center (off)
position.
Electronic Speed Control:
Baldor SmartMotor® Inverter-Duty models have an
electronic keypad variable speed control. Speed range is
180 to 3600 RPM.
Mechanical Speed Control:
Units with the mechanical variable speed belt drive have a
speed range of 600 to 4000 RPM.
Turning the hand-wheel at the rear of the disperser varies
the speed. For best results always stop and start the
disperser in the lowest variable speed hand-wheel setting.
NOTE:
DO NOT TURN THE HAND-WHEEL KNOB WHEN THE
DISPERSER IS NOT RUNNING !

Maintenance
Maintaining your mixer is not difficult if you follow these
guidelines:
• Keep the mixer clean.
• Check all wiring on a regular basis and repair as needed.
• Unit fails to start: Check power source to unit, check
-and/or- reset breaker. If problem continues, disconnect
power and have a qualified person make proper repairs.
• Ensure the dispersion blade is fastened securely to the
shaft.

(top view)
Blade Rotation:
Ensure the mixer shaft will rotate in a clock-wise direction,
looking downward into the container. Care must be taken
to ensure blade is rotating in the correct direction. Look for
arrow on blade or consult factory.

Blade Changing:
ENSURE POWER TO UNIT IS OFF OR DISCONNECTED!
Remove the bolt from the bottom of the shaft, remove and
replace the blade and replace the bolt.

Mechanical Variable Speed Drive
• Avoid using automotive chassis and other non-
interchangeable lubricants. Lubricated pulleys will stick
or freeze if not lubricated properly. The most frequent
cause is failure to run the drive through part of its range
at the time it is lubricated. The pulley must be lubricated
periodically and pulley adjustment opened and closed to
distribute the grease inside. Small amounts of grease
will do. Wipe excess off of belt faces.
• Check belt alignment. Misalignment will cause the belt
to overheat and wear rapidly.
• Watch for overload conditions. If the belt loops out or
squeals the drive is overloaded. This condition will
frequently exist during start-up but should not continue
for more than a few seconds. When starting up,
particularly if starting several times a day, try to start
up slowly by jogging the machine to bring the speed up
gradually.
• Excessive vibration will cause damage to all of the
equipment in the drive system. If any doubt exists as
to the safe levels of vibration a qualified person should
be called in to examine the drive.
• Use Loctite on set screws where necessary to prevent
screws from backing out due to vibration in machine.
• Air Valve ~ Cylinder speed control adjustment:
Air flow adjusting screw:
- screw in until desired
lowering speed is
obtained.
Air flow adjusting screw:
- screw out until desired
lifting speed is obtained.
Once desired raise &
lowering speeds are
obtained, tighten lock-nuts.

Electric Motor Data, fixed speed
General:
Electric motors are wired to operate in a Clockwise rotation, when
viewed from top of mixer looking downward into the mixing
container.
The mixers are supplied with the following power connections:
• 115 volt single-phase totally enclosed (TEFC) motors are wired
at our factory for correct rotation. All single-phase TEFC models
are equipped with cord, plug and switch assembly that are ready
to operate.
• 230/460 volt three-phase and all explosion-proof motors must
be field wired for proper rotation. Three-phase and explosion-
proof models are equipped with motor leads only. Refer to the
connection diagrams on the motor.
• DC Variable-speed models, the speed controller is mounted
and pre-wired directly to mixer.
- 115 volt single-phase totally enclosed (TEFC) motors are wired
at our factory for correct rotation. These models are equipped
with cord, plug and switch assembly that are ready to operate.
- 230 volt single-phase totally enclosed (TEFC) motors are wired
at our factory but have no plug.
Described below are the most commonly used electric motor
enclosure types on your INDCO mixer:
TEFC - Totally Enclosed Fan Cooled - no ventilation openings in
housing (but not airtight, waterproof, or explosion-proof). Includes
an external fan, in a protective shroud, to blow cooling air over
the motor. Used in locations which are dirty or dusty.
TENV - Totally Enclosed Non-Ventilated - no ventilation openings
in housing (but not airtight, waterproof, or explosion-proof). Relies
on convection for cooling. Used in locations which are dirty or
dusty.
EP - Explosion-Proof - a totally enclosed design to withstand an
internal explosion of specified gases or vapors and not allow the
internal flame or explosion to escape. Explosion-Proof motors
are individually rated for specific gases, vapors & conditions. Most
INDCO EP motors are Class I, Group D & Class II, Group F & G
rated.
Warning:
These instructions must be followed to ensure safe and proper
installation, operation and maintenance of the motor. They should
be brought to the attention of all persons who install, operate or
maintain this equipment. Failure to follow instructions and safe
electrical procedures could result in serious injury or fatality.
Disconnect all power and discharge all capacitors before servicing.
Install and ground per local and national codes. Consult qualified
personnel with questions or if repairs are required.
Electrical Connections:
If your new mixer has not been supplied with a power cord
assembly by INDCO, see information below and consult your
local electrician or electrical code for proper size requirements.
1. All wiring, fusing and grounding must comply with National
Electrical Codes and local codes.
2. To determine proper rotation and voltage connections, refer
to the information and diagram on the nameplate, separate
connection plate or decal. If the plate or decal has been
removed, contact INDCO or the motor manufacturer for
assistance.
3. Use the proper size of line current protection and controls
as required by the National Electrical Code and local
codes. Recommended use is 125% of full load amps as
shown on the nameplate for motors with 104°F (40°C)
ambient and a service factor over 1.0. Recommended use
is 115% of full load amps as shown on the nameplate for
all other motors. Do not use protection with larger
capacities than recommended. Three phase motors must
have all three phases protected.
Location:
In selecting a location for the motor, consideration should be given
to environment and ventilation. A motor with the proper enclosure
for the expected operating condition should be selected.
The ambient temperature of the air surrounding the motor should
not exceed 104°F (40°C) unless the motor has been especially
designed for high ambient temperature applications. The free
flow of air around the motor should not be obstructed.
The motor should never be placed in a room with hazardous
process, or where flammable gases or combustible material may
be present, unless it is specifically designed for this type of service.
1. Drip proof (open) motors are intended for use indoors where
atmosphere is relatively clean, dry and noncorrosive.
2. Totally enclosed motors may be installed where dirt, moisture
and corrosion are present.
3. Totally enclosed – severe duty motors are recommended for
extreme environmental conditions.
4. Explosion proof motors are built for use in hazardous
locations as indicated by Underwriters’ label on motor.
Consult UL, NEC and local codes for guidance.
Changing Rotation:
1. Keep hands and clothing away from rotating parts.
2. Before the motor is coupled to the load, determine proper
rotation.
3. Check rotation by jogging or bumping. Apply power to the
motor leads for a short period of time, enough to just get
motor shaft to rotate a slight amount to observe shaft-rotating
direction.
4. Three phase – interchange any two (2) of the three- (3) line
leads. Single phase – reconnect per the connection diagram
on the motor.
Inverter Control Data
If your HS Series mixer has the electronic inverter-duty
variable speed control, see enclosed Baldor owners manual.

Full Load Current Specifications
Note: The following table is a general guide only and are for normal duty applications. The exact specifications for any given motor
can vary from those listed below, see actual motor nameplate for exact specifications.
Temperature Limits - Insulation Classification
Below are the temperature limits for some electric motors.
Most INDCO mixers have insulation class ‘B’ and some have class ‘F’ ratings.
Class Maximum Ambient Maximum Heat Rise Maximum Operating Temperature
A 104°F 117°F 221°F
B 104°F 162°F 266°F
F 104°F 207°F 311°F
H 104°F 252°F 356°F
Operation:
1. Ensure that voltage and frequency stamped on motor
nameplate corresponds with that of the power line.
2. Check all connections to the motor with the wiring diagram.
3. Be sure rotor turns freely when disconnected from the load.
Any foreign matter in the air gap should be removed.
4. Leave the motor disconnected from the load for the initial
start. Check for proper rotation. After the machine is coupled
to the load, check the nameplate amps are not exceeded.
Shut down the motor if the above parameters are not met or if
any other noise or vibration disturbances are present. Consult
NEMA guidelines or the equipment manufacture if any questions
exist before operating equipment.
Allowable Voltage & Frequency Range:
If voltage and frequency are within the following range,
motors will operate, but with somewhat different
characteristics than obtained with correct nameplate values.
1. Voltage: Within 10% above or below the value stamped
on the nameplate. On three phase systems the voltage
should be balanced within 1%. A small voltage
unbalanced will cause a significant current unbalance.
2. Frequency: Within 5% above or below the value
stamped on the nameplate.
3. Voltage and frequency together: Within 10% (providing
frequency above is less than 5%) above or below
stamped on the nameplate.
Cleanliness:
Keep both the interior and exterior of the motor free from
dirt, water, oil and grease. Motors operating in dirty places
should be periodically disassembled and thoroughly
cleaned. NOTE: Explosion proof motors should only be
disassembled by an authorized service station.
Condensation Drain Plugs:
All explosion proof and some totally enclosed motors are
equipped with automatic drain plugs, they should be free of
oil, grease, paint, grit and dirt so they don’t clog up. The
drain system is designed for normal floor (feet down)
mounting. For other mounting positions, modification of
the drain system may be required, consult the manufacture.
Service:
Warning - Disconnect power before working on motor or
driven equipment. Motors with automatic thermal protectors
will automatically restart when the protector temperature
drops sufficiently. Do not use motors automatic thermal
protectors in applications where restart will be hazardous
to personnel or equipment.
Caution - Over greasing bearings can cause premature
bearing and/or motor failure. The amount of grease added
should be carefully controlled.
Note - If lubrication instructions are shown on the motor
nameplate, they will supersede this general instruction.
Some electric motors are pre-greased with a polyurea
mineral oil NGLI grade 2-type grease unless stated
otherwise on the motor nameplate. Some compatible
brands of polyurea mineral base type grease are: Chevron
SRI #2, Rykon Premium #2, Shell Oil Dolium R or Texaco
Polystar RB.
Motors are properly lubricated at time of manufacture. It is
not necessary to lubricate at the time of installation unless
the motor has been in storage for a period of 12 months or
longer.

Problem or Complaint
Motor is NEW (or basically new)
and has a cord, plug, and switch
by INDCO. It does not start or
run.
Motor is NEW (or basically new)
and was wired up by USER. It
does not start or run.
Motor started to smoke, got hot
to the touch, and/or developed a
burning smell after running a
while. May or may not shut off
automatically.
Motor pulling too many amps
(more amps than allowed on the
motor nameplate)
Motor is creating or throwing
sparks.
Possible Cause
1. Switch is bad, or switch could have been damaged in shipment.
Could also have a damaged cord (partially cut or torn, insulation on
cord missing, etc.).
2. User could be trying to run motor on the wrong voltage or wrong
phase.
3. Motor’s internal starter switch or capacitor could be defective. (A
tip here is that when turned on, the motor hums but does not turn.
Also, sometimes the motor shaft can be spun manually, and the
motor will then take off and run normally).
4. Motor could have taken a blow in shipping, and fan could be
jammed inside fan cover or against motor body. (Fan cover will
likely be cracked or broken).
5. If mixer is gear-drive, or has another type of transmission on it
(hydrostatics, pulleys, etc.), check to ensure the problem is not is
the transmission. Might not be a problem with the motor at all.
1. Installer may not have followed the directions on the motor name-
plate correctly with regards as to how to wire up the motor. May
have wired at the wrong voltage or wrong phase, may have wired
backwards, may have not taped off the proper leads, etc.
2. See above Section (where INDCO wired the motor).
1. Motor is probably being overloaded. If motor/mixer is new, then
check to see if it was sized correctly (viscosity, S.G., tank volume,
HP, direct vs. gear drive, etc.) If it is not new, maybe customer put
a new impeller on it recently, or tried to put the mixer into a larger
tank or is using it with a thicker liquid.
2. If motor is new, then it could be a bad motor. If the mixer is sized
properly for the customer’s task (ask a Sales Engineer for help if
needed!), then this is a distinct possibility.
TIP: Motors DO get hot normally! See information on Tempera-
ture Limits - Insulation Classification for details.
1. Just another way of stating that the motor is probably being over-
loaded.
2. Could be a bad motor (same as previous).
1. If sparks are coming from FAN COVER or FAN AREA, there is
probably a piece of loose metal striking the inside of the fan hous-
ing.
2. If sparks are coming from JUNCTION BOX or other cover where
electrical connections are housed, there could be a loose connec-
tion, or arcing caused by missing insulation or wire nut, etc.
3. If motor has ODP enclosure, and sparks are visible in motor wind-
ing area, this is probably NORMAL. ALL motors produce “sparks”
in and around the windings as part of their normal operation. In
totally enclosed motors, however, you just cannot see them.
Remedy
1. Replace switch, cord, or both as necessary.
2. Reconnect motor to correct phase or voltage electri-
cal supply.
3. Motor cannot be repaired by the user or by INDCO.
Replace motor with a new one.
4. Remove fan cover and fan. Turn on motor to make
sure it runs now that damaged parts are removed. We
can send new fan and cover. (NOTE: Do not run motor
for more than a few minutes without fan to cool it!!).
5. Replace or repair components as necessary.
1. Re-examine motor nameplate for correct information
and re-wire motor.
2. See above Section (where INDCO wired the motor).
1. Replace motor on mixer with one appropriate to the
customer’s task. Alternately, replace impellers with a
size that the present motor will handle, or reduce batch
size, etc.
2. Replace motor.
TIP: If the same thing happens a second time, then it
was probably NOT the motor. Look harder at applica-
tion. Might be prudent to replace motor with a size larger
if there is any concern.
1. Same remedy as previous.
2. Same as above.
1. Remove debris. Replace broken parts.
2. Open junction box, repair loose connection or wiring.
3. Nothing to do. If this is worrisome, replace with mo-
tor with a different enclosure style.
Electric Motor - Troubleshooting
page 8 of 11

INDCO, Inc. M-M-30118 mixer manual HS-5 date: 3/8/05
Problem or Complaint
Motor runs fine when no load is
applied. When loaded, it loses
power and tries to stall.
Motor shocks the user when they
touch it.
Exterior of electric motor is rust-
ing.
Electric motor (or whole mixer)
appears to vibrate at more than
normal levels.
Possible Cause
1. If motor is new, see above under possible overload situation, or
possible bad motor.
2. If motor is older, and motor is AC, then it is probably worn out or
in need of rebuilding.
3. If motor is older, and motor is DC, then it probably needs new
brushes. Brushes are present in all DC motors. (AC motors do not
have brushes).
1. Motor ground is faulty. If motor is new, then the grounding wire
was not secured adequately. If the motor is older, the ground wire
has probably worn or shaken loose.
1. If the paint has chipped or worn off of the motor, this is normal.
Much of the electric motor body is either cast iron or steel. The
paint used by most motor manufacturers is a epoxy-base or lac-
quer-base, which are pretty durable, but they could eventually come
off.
1. If report of problem is seen primarily at a specific speed or
within a specific speed range, it could be the normal harmonic
frequency vibration that is integral to any machine. Basically, ALL
rotating parts have a fairly specific point at which they will not rotate
smoothly…that is, without some level of vibration. There is going to
be an RPM (or fairly narrow RPM range) where you will notice an
increase in vibration. This is even more common to witness on
variable speed mixers. It is also much more pronounced when run-
ning the mixer dry (out of liquid, in free air).
2. Could be a bad chuck or coupler attached to the motor, could be
a bent mixing shaft, or could be a propeller or blade which needs
to be balanced better.
3. Possible that motor shaft is bent. Would probably only happen
if motor was brand new would have taken a blow during shipping to
bend it, or dropped.
Remedy
1. Repair as mentioned previously, or examine customer
application more closely.
2. Replace motor. NOTE: INDCO cannot rebuild elec-
tric motors, although it can be done. If customer wants
to pursue this, they can check their local Yellow Pages
under “Electric Motor Repair” . Alternately, we can refer
them to a factory-authorized repair facility if we have the
brand name of the motor.
3. Replace brushes. Inspect brush holders while ser-
vicing, they wear with time as well.
1. Repair or reattach ground wire, or replace cord if nec-
essary.
1. Clean or buff rust off, and re-paint the motor (if it is a
problem). If it IS a serious problem, consider an ALL-
STAINLESS motor.
1. DO NOT OPERATE A MIXER WITH THE SHAFT &
IMPELLER OUT OF LIQUID! Damage to motor, shaft,
bearings, etc. will result! If vibration is distressing, and
mixer is variable speed, try to avoid the rather small
“band” of the speed range at which the most vibration is
seen (basically, operate mixer at either higher or lower
speeds than the higher-vibration “band”).
2. Replace the faulty part. Test to see if shaft is bent by
removing and rolling it across a flat table or floor. Chuck
or coupler could be visibly off-center or wobbling. May
have to switch out parts until problem is solved.
3. Replace motor (probably out of the question to at-
tempt repair).
