INITIAL INSPECTION
1. Upon receipt of your Brawn Mixer, check for possible
shipping damage. Report any damage immediately
to the carrier and to Brawn Mixer.
2. All Brawn Mixers are shipped with the shaft and
impeller(s) disassembled from the drive assembly.
3. Storage: Mixers should not be stored near vibrating
machinery to avoid damage to the bearings. Store
mixers as packaged by the factory. For longer
storage periods, consult factory. If electric motors
have been subjected to humid conditions, check the
insulation resistance between phase and mass and
between the different phases. The resistance should
not be less than 100 megohms. If the resistance is
less, please consult the factory. If mixer is stored for
more than a year, the condition of the gear lubricant
should be checked before the mixer is put in
operation (see lubrication instructions).
INSTALLATION
[REFER TO ASSEMBLY / DIMENSION DRAWING]
Refer to the mixer installation / assembly drawing for
important mounting structure design, assembly,
mounting and dimensional data.

BOLT-TIGHTENING RECOMMENDATIONS:
Inadequately or improperly tightened hardware can
loosen, due to vibration during mixer operation. This can
result in reduced mixer life or damage to equipment.
Recommended torque values for tightening all in-tank
and mounting hardware are listed in TABLE 1. These
average torque values should be considered only as a
guide and not as absolute values.
SHAFT & IMPELLER ASSEMBLY
If an optional rigid shaft coupling is furnished, connect
the mixer shaft and rigid driveshaft couplings by carefully
engaging the shaft rabbeted faces and installing the
mounting hardware. Be careful not to damage the
coupling faces or rabbets, as this can cause excessive
shaft run-out that will affect the life of the mixer
Proper hollow output shaft installation is shown in
FIGURE 1, PAGE 3.
1. Inspect the shaft surface for evidence of damage
and repair, if required, before installing the shaft into
hollow output shaft or connecting to flanged
coupling.
2. Attach the shaft collar (Item 5) to the mixer shaft
(Item 4).

FIGURE 1: SHAFT INSTALLATION
For Installing Impellers without a Hook Key
Inspect the impeller bore and shaft surface for evidence
of damage and repair, if required, before installing the
impeller(s) on the shaft. Install the impeller(s) on the
mixer shaft by carefully sliding the impeller hub over the
shaft to its proper location and tighten the set screws. It
is recommended that the shaft be spotted with a drill
point at the setscrew locations to prevent loosening of
the impeller(s).
For Installing Impellers with a Hook Key
To install the impeller on the shaft, slide the impeller hub
over the mixer shaft, place the hook key in position,
lower the hub over the hook key and tighten the set
screw. The set screw must seat in the countersunk hole
in the hook key. Proper impeller mounting is illustrated in
FIGURE 2.

START UP
1. All units are lubricated before shipment. The
lubricant level should be checked with the unit
mounted in its correct operating position. Lubricant
should be added or removed to bring it to the correct
level.
2. Connect the motor in accordance with the motor
nameplate. The motor starter should incorporate
overload protection. Before operating the mixer, jog
the motor and observe mixer shaft rotation. Proper
rotation is clockwise, as viewed from the top, unless
otherwise noted.
3. Check all bolts and fasteners for tightness. It is good
maintenance practice to recheck all bolts after two
weeks of operation and periodically thereafter. Refer
to TABLE 1 for recommended torque values.
4. Do not attempt to start mixer with impellers buried in
solids or solidified liquids.
CAUTION
Do not operate mixer with the tank empty or the lowest
impeller submerged with less than ½ of the impeller
diameter of liquid above it. Damage to the mixer and/or
mounting structure may result.
ELECTRIC MOTORS
This equipment contains HAZARDOUS VOLTAGES,
ROTATING PARTS AND HOT SURFACES. SEVERE
PERSONAL INJURY OR PROPERTY DAMAGE CAN
RESULT IF SAFETY INSTRUCTIONS ARE NOT
FOLLOWED. Only qualified personnel should work on or
around this equipment after becoming thoroughly familiar
with all warnings, safety notices, and maintenance
procedures contained herein. The successful and safe
operation of this equipment is dependant upon proper
handling, installation, operation and maintenance.
WARNING
Explosion-proof motors-these motors are constructed to
comply with the U.L. Label Service Procedure Manual.
When repairing and reassembling a motor that has an
underwriter’s label, it is imperative that the unit be
reinspected and:
1. All original fits and tolerance be maintained.
2. All plugs and hardware be securely fastened.
3. Any parts replacements, including hardware, be
accurate duplicates of the originals.
Repair work on explosion-proof motors can only be done
by the original manufacturing or U.L. certified shops.
Violations of any of the above items will invalidate the
significance of the U.L. Label.
STORAGE
Motors must be stored in a clean, dry, well ventilated
location free from vibration and rapid or wide
temperature variations. If the unit is to be stored longer
than three months, consult factory. Ball bearing motors
are shipped from the factory properly lubricated and
ready to operate. When in storage, the motor shaft must
be turned several rotations every month and bearings
relubricated every year. On non-explosion-proof TEFC
motors, a removable plug in the bottom of the frame or
housing permits removal of accumulated moisture. Drain
regularly if storage atmosphere results in formation of
condensation.

ELECTRIC MOTORS, Cont.
INSTALLATION
Installation must be handled by qualified service or
maintenance personal.
OPERATION
CAUTION
Repeated trial starts can overheat the motor and may
result in motor burnout. If repeated trial starts are made,
allow sufficient time between trials to permit heat to
dissipate from windings and rotor to prevent overheating.
Starting currents are several times running currents, and
heating varies as the square of the current.
After installation is completed, but before motor is put in
regular service, make an initial start as follows:
1. Check motor starting and control device
connections against wiring diagrams.
2. Check voltage, phase, and frequency of line circuit
(power supply) against motor nameplate.
3. If possible, remove external load (disconnect drive)
and turn shaft by hand to ensure free rotation. This
may have been done during installation procedure;
if so, and conditions have not changed since, this
check may not be necessary.
a. If drive is disconnected, run motor at no load
long enough to be certain that no unusual
conditions develop. Listen and feel for
excessive noise, vibration, clicking, or
pounding. If present, stop motor immediately.
Investigate the cause and correct before
putting motor in service.
b. If drive is not disconnected, interrupt the
starting cycle after motor has accelerated to
low speed. Carefully observe for unusual
conditions as motor coasts to a stop.
4. When checks are satisfactory, operate at minimum
load and look for unusual condition. Increase load
slowly to maximum. Check unit for satisfactory
operation.
CAUTION
Guard against overloading. Overloading causes
overheating and overheating means shortened insulation
life. A motor subjected to a 10°C temperature rise above
the maximum limit for the insulation may cause the
insulation life to be reduced by 50%. To avoid
overloading, be sure motor current does not exceed
nameplate current when nameplate voltage is applied.
Electric motors operating under normal conditions
become quite warm. Although some places may feel hot
to the touch, the unit may be operational within limits.
Use a thermocouple to measure winding temperature.
The total temperature, not the temperature rise, is the
measure of safe operation. Investigate the operating
conditions if the total temperature measured by a
thermocouple placed on the windings exceeds:
230°F (110°C) for class “B” insulation
275°F (135°C) for class “F” insulation
302°F (150°C) for class “H” insulation
VOLTAGE REGULATION
Motors will operate successfully under the following
conditions of voltage and frequency variation, but not
necessarily in accordance with the standard established
for operation under rated conditions:
1. When the variation in voltage does not exceed
10% above or below normal, with all phases
balanced.
2. When the variation in frequency does not exceed
5% above or below normal.
3. When the sum of the voltage and frequency of the
voltage does not exceed 10% above or below
normal (provided the frequency variation does not
exceed 5%).
MAINTENANCE
Failure to properly maintain the equipment can result in
severe personal injury and product failure. The
instructions contained herein should be carefully
reviewed, understood and followed. The following
maintenance procedures should be performed regularly:
1. Bearing lubrication (When regreaseable bearings
are supplied)
2. Insulation resistance check
3. Cleaning

ELECTRIC MOTORS, Cont.
This checklist does not represent an exhaustive survey
of maintenance steps necessary to ensure safe
operation of the equipment. Particular applications may
require further procedures
Dangerous voltages are present in the equipment which
can cause severe personal injury and product failure.
Always de-energize and ground the equipment before
maintenance. Maintenance should be performed only by
qualified personal.
The use of unauthorized parts in the repair of the
equipment, tampering by unqualified personal, or
removal or alteration of guards or conduit covers will
result in dangerous conditions which can cause severe
personal injury or equipment damage. Follow all safety
instructions contained herein.
BEARING LUBRICATION
(When regreaseable bearings are supplied)
CAUTION
Do not lubricate motor while in operation, since excess
grease will be forced through the bearings and into the
motor before it will force its way out the drain plug.
Excess grease accumulation on windings reduces
insulation life.
Prior to shipment, motor bearings are lubricated with the
proper amount and grade to provide six months of
satisfactory service under normal operation and
conditions.
For best results, grease should be compounded from a
polyurea base and a good grade of petroleum oil. It
should be of No. 2 consistency and stabilized against
oxidation. Operating temperature ranges should be from
-15°F to +250°F for class B insulation, and to +300°F for
class F and H. Most leading oil companies have special
bearing greases that are satisfactory.
Relubricate bearings every six months (more often if
conditions require), as follows:
1. Stop the motor. Lock out the switch.
2. Thoroughly clean off pipe plugs and remove
from housings.
3. Remove hardened grease from drains with stiff
wire or rod.
4. Add grease to inlet with hand gun until small
amount of new grease is forced out drain.
5. Remove excess grease from ports, replace inlet
plugs, and run motor ½ hour before replacing
drain plug.
6. Put motor back in operation.
INSULATION RESISTANCE
Check insulation resistance periodically. Any approved
method of measuring insulation resistance may be used,
provided the voltage across the insulation is at a safe
value for the type and condition of the insulation. A hand
crank megger of not over 500 volts is the most
convenient and safest method. Standards of the Institute
of Electrical and Electronics Engineers, Inc., recommend
that the insulation resistance of the stator windings at 75°
C, measured at 500 volts dc, after one minute should not
be less than:
Rated Voltage of Machine + 1000
=
Insulation Resistance
1000
in Megohms
This formula is satisfactory for most checks. For more
information, see IEEE Standard No. 43 “Recommended
Practice for Insulation Resistance Testing of AC Rotating
Machinery.”
CLEANING
WARNING
Do not attempt to clean the motor while it is operating.
Contact with rotating parts can cause severe personal
injury or property damage. Stop the motor and lock out
switch before cleaning.
The motor exterior must be kept free of oil, dust, water,
and chemicals. For fan cooled motors, it is particularly
important to keep the air intake openings free of foreign
material. Do not block air outlet or inlet.
On non-explosion-proof TEFC motors, a removable plug
in the bottom center of the motor frame or housing
permits removal of accumulated moisture. Drain
regularly.

MAINTENANCE / LUBRICATION
Gear units should have the oil changed every 2,500
hours or six months. If synthetic lubricant is used, it
should be changed every 6,000 hours or 2 years. For
adverse operating conditions, the interval should be
shorter. DO NOT MIX SYNTHETIC AND MINERAL
BASE OILS. Units should be checked periodically for
increased noise, surface temperature, vibration, shaft
movement and amperage draw. Units with inspection
covers should not be operated with the inspection cover
removed.
CAUTION
Oil should be changed more often if reducer is used in a
severe environment. (i.e. dusty, humid)
TABLES 2 and 3offer suggestions on the viscosity and
manufacturers of recommended lubricants. Some gear
lubricants contain E.P. additives that can be corrosive to
gear bronze. Avoid lubricants that are compounded with
sulfur and/or chlorine.
Always check for proper oil level after filling. Capacities
vary somewhat with model and mounting position. Oil
should rise to bottom edge of level hole. Do Not Overfill.
