OM-TDB TA/2
Equipment Description
The Groen TA/2 assembly is an electrically
powered mixer with dual counter rotating
agitators, which is incorporated into Groen
kettles of 20 or 40 quart capacity.
The agitator frame is constructed of tubular
stainless steel and fitted with scrapers. It is
easily removed for cleaning.
Installation and Start-Up
WARNING
TURN OFF POWER AT THE CIRCUIT
BREAKER PRIOR TO INSTALLATION.
THE MIXER MUST BE INSTALLED BY
PERSONNEL WHO ARE QUALIFIED TO
WORK WITH ELECTRICITY. IMPROPER
INSTALLATION CAN RESULT IN INJURY
TO PERSONNEL AND/OR DAMAGE TO
EQUIPMENT.
The mixer has a variable speed drive with
electrical speed control that powers on 1/2 HP
motor.
For a description of the kettle component of
your cooker/mixer, see the separate kettle
manual.
2. Provide the proper electric power supply as
specified on the electrical information plate
attached to the mixer. Observe local codes
and/or The National Electrical Code in
accordance with ANSI/NFPA 70 - latest
edition. The installation must conform to the
code that has the more strict requirements.
3. TA/2 mixer requires a seperate 120V, 60Hz,
15 Amp outlet. Unit is provided with a 6 ft.
long cord and grounded plug.
WARNING: DO NOT cut off the ground plug.
4. Electrical service for the kettle will
require a separate connection. See
specific kettle manual.
the
ANY MECHANICAL OR ELECTRICAL
CHANGE MUST BE APPROVED BY THE
GROEN FOOD SERVICE ENGINEERING
DEPARTMENT.
Your Groen mixer has been test operated at the
factory and is furnished with all internal wiring. It
is complete and ready for final connection. A
wiring diagram is furnished at the rear of this
manual.
A. Installation is as follows:
1. Set the cooker/mixer in place and level it. If
the mixer is a tilting model, confirm that there
is enough rear or side clearance, depending
on model, and overhead clearance to tilt the
mixer safely through its entire tilting range.
Provide enough clearance to permit access
for service as well. Fasten the cooker/mixer
to the floor or deck to reduce chances that
the unit could tip over if unit is provided with
flanged feet.
WARNING
TO PREVENT POSSIBLE ELECTRIC
SHOCK, GROUND THE UNIT AT THE
TERMINAL PROVIDED.
5. Use the following check list to confirm that
the installation is correct.

! Access for service
! Unit fastened down
! Mixer power supply conforms to
information plate and code
! Electrical conduit and connections are
waterproof
! Mixer grounded
For instructions on installing the kettle
component of your cooker/mixer, see the
separate kettle manual.
B. Initial Start-Up
After the mixer is installed, take the following
actions to confirm that the equipment is
operating correctly.
1. Tilt the mixer through its complete tilting
range to ensure that there is no hazard or
interference.
WARNING
TURN OFF AGITATOR BEFORE ADDING
INGREDIENTS OR INSPECTING KETTLE
CONTENTS. DO NOT WEAR LOOSE
CLOTHING OR JEWELRY AROUND
OPERATING MIXER KETTLE. KEEP WELL
CLEAR OF ROTATING MIXER ARMS AND
PADDLES AT ALL TIMES.
2. Make sure the agitator is properly coupled
with its drive shaft. If the mixer has a slip-on
coupling, the drive pin must be positioned at
the end of the J-slot.
3. When the mixer is in operating position,
every scraper blade should touch the inside
of the kettle during at least part of each
revolution of the agitator.
d. At the circuit breaker or fuse box, turn on the
electric power supply to the mixer.
e. Switch on the drive and confirm that the
mixer operates smoothly. For a variable
speed model, confirm that the mixer
operates correctly throughout its speed
range.
f. Make sure the agitator turns in the correct
direction, so it pushes the nylon scraper
blades ahead of the agitator bar.
If the unit functions as described above, it is
ready for use. If the unit does not function as
intended, call your local Groen authorized
service agency.
Slip-On Coupling
For instructions on initial start-up of the
kettle component of your cooker/mixer, see
the separate kettle manual.

Operation
WARNING
TURN OFF AGITATOR BEFORE ADDING INGREDIENTS OR INSPECTING KETTLE CONTENTS.
DO NOT WEAR LOOSE CLOTHING OR JEWELRY AROUND OPERATING MIXER KETTLE. KEEP
WELL CLEAR OF ROTATING MIXER ARMS AND PADDLES AT ALL TIMES.
1. Before you operate the mixer, make sure
that the agitator is firmly connected with the
drive shaft and properly positioned in the
kettle. The agitator must be positioned so
every scraper blade touches the kettle
during at least part of each revolution. To
connect the agitator:
a. Slip-on Coupling: Slide the coupling up
onto the shaft as far as it will go. Then
turn the agitator and pull it down, so that
the drive pin on the shaft becomes firmly
seated against the end of the J-slot.
2. If the mixer has been tilted up, lower it into
operating position.
WARNING
THE UNIT IS EQUIPPED WITH AN
AUTOMATIC TILT CUTOFF SWITCH. IF
POWER IS ON WHEN A TILTED MIXER IS
LOWERED INTO OPERATING POSITION,
THE MIXER CAN AUTOMATICALLY
START.
a. On a variable speed drive with electrical
speed control, turn the speed adjustment
knob.
CAUTION
UNDER HEAVY LOAD DO NOT RUN THE
MIXER CONTINUOUSLY AT SLOWER
THAN 5% OF FULL SPEED. SLOWER
OPERATION COULD DAMAGE THE SPEED
CONTROL.
6. To stop the mixer, switch off the drive. Set
the drive to low speed before switching it off.
If the cooker/mixer will be cleaned or
serviced, or will not be used for a week or
longer, cut off all power supplies to the unit
at the circuit breaker or fuse box.
7. Switch off the drive, before you tilt the mixer.
To tilt the mixer, first unlatch it (See
Photograph). For some units, you may need
to tilt the kettle forward slightly to let the
agitator clear the kettle wall as you tilt the
mixer.
3. Turn on electric power to the unit at the
circuit breaker or fuse box.
4. Switch on the drive.
5. Set the desired mixing speed.
CAUTION
STARTING WITH THE MIXER SET AT HIGH
SPEED MAY CAUSE MATERIAL TO SPILL
OUT OF THE KETTLE ON VARIABLE
SPEED UNITS.
8. As you tilt the mixer out of the kettle, clean
any clinging product from the agitator, so
product will not drip onto the outside of the
kettle or surroundings, and so the weight of
product will not make the mixer fall down.
To operate the kettle component of your
cooker/mixer, see the separate kettle manual.

Cleaning
OM-TDB TA/2
A. Suggested Tools & Materials.
1. A good stainless steel cleaner.
2. Stiff brush.
3. Sanitizer Solution.
B. Precautions
BEFORE CLEANING ANY PART OF THE
MIXER, OTHER THAN THE AGITATOR,
SHUT OFF ALL ELECTRIC POWER TO THE
CO O KER / MI X ER AT THE CI R C U IT
BREAKER OR FUSE BOX, TO AVOID
POSSIBLE ELECTRIC SHOCK.
KEEP WATER AND SOLUTIONS OUT OF
THE CONTROLS, ELECTRICAL WIRING,
AND DRIVE MECHANISM. NEVER SPRAY
OR HOSE THE MIXER.
C. Procedure
1. Wash the agitator as soon as possible after
2. Disassemble the scrapers and clean them
WARNING
use. If the unit is in continuous use,
thoroughly clean and sanitize all parts of the
mixer at least once every 12 hours
along with the rest of the agitator, then
reassemble them.
WARNING
4. To remove materials stuck to the agitator,
use a brush, sponge, cloth, plastic or rubber
scraper, or plastic wool along with the
cleaning solution. To make washing easier,
let the cleaning solution soak into the
residue. When you clean the stainless steel
parts, do not use any abrasive material (like
metal sponges or scouring powder) or metal
implement (like a spoon, scraper, or wire
brush) that might scratch the surface.
Scratches make the surface hard to clean
and provide places for bacteria to grow. Do
not use steel wool, which may leave
particles imbedded in the surface and cause
eventual corrosion and pitting.
5. As part of the daily cleaning program, clean
all surfaces that may have been soiled.
Remember to check such parts as the back
and underside of the drive housing.
6. When the agitator needs to be sanitized, use
a sanitizing solution equivalent to one that
supplies 100 parts per million available
chlorine. Obtain advice on the best sanitizing
agent from your supplier of sanitation
products. Following the supplier’s directions,
apply the sanitizer after the agitator has
been washed, then rinse off the sanitizer
completely. It is recommended that the
agitator be sanitized just before use.
CAUTION
NEVER LEAVE A SANITIZER IN CONTACT
WITH THE SURFACE OF STAINLESS
STEEL LONGER THAN 20 MINUTES.

3. Prepare a hot solution of the cleaning
compound as instructed by the supplier.
Wash the agitator parts and rinse them well.
Use a cloth moistened with the cleaning
solution to clean other parts of the mixer.
Cleaning procedures for the kettle component of
your cooker/mixer are described in the separate
