EQUIPMENT DESCRIPTION
The Groen INA/2 assembly is an electrically powered mixer with an inclined agitator, which is incorporated into Groen kettles of 40 to 80 gallon capacity. The
patented design provides a gentle lifting and folding action which avoids the build-up of heavy particles at the bottom of the kettle. This action is uniquely efficient
in preparing such products as stews, ground meat, pie fillings, franks and beans, and similar items.
The agitator frame is constructed of tubular stainless steel and fitted with shovel-type scrapers. It is easily removed for cleaning. The mixer has a variable speed
drive with electrical speed control.
For a description of the kettle component of your cooker/mixer, see the separate kettle manual.

TERMINAL PROVIDED.
A. Installation
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. 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.
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. Your mixer requires a permanent connection with the electrical service.
Use waterproof conduit and waterproof connectors for this connection.
4. Any electrical service for the kettle will require a separate connection. See
the specific kettle manual.
5. Use the following check list to confirm that the installation is correct.
Unit level
Adequate clearance for tilting
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
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.
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.
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. If a bolted coupling is employed, the bolts must be turned to the
proper position and the nuts must be tightened.

Slip-On Coupling
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.
4. At the circuit breaker or fuse box, turn on the electric power supply to the
mixer.
5. 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.
6. 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.
For instructions on initial start-up of the kettle component of your cooker/
mixer, see the separate kettle manual.
