Equipment Description

Groen TA/2 is an electrically powered, twin shaft mixer, which is mounted on Groen kettles with

capacities of 20 to 40 quarts. The mixer is mounted with a kettle on a common base. To permit easy

cleaning of the equipment and emptying of the kettle, a hinge in the pedestal allows the mixer to be

tilted back out of the kettle.

Model TA/2 has a motor (1/2 HP or optional 3/4 HP) that drives removable agitators through a com-

bination of belt and gears. Th»stainless steel agitators consist of a primary agitator, which continu-

ously scrapes the bottom and side of the kettle with nylon fingers, and a faster, counter rotating,

secondary agitator, which operates between the center line and the wall of the kettle.

Controls for the mixer are an on/off power switch and a variable speed adjustment knob. For safety,

the mixer is also equipped with an automatic tilt cutoff switch. All controls and drive components are

enclosed in a stainless steel console with a No. 4 finish.

Installation of the TA/2 requires connection to a 120 or 240 V, 1 PH, 50 or 60 HZ electrical service.

If the mixer is employed with an electrically heated kettle, a separate electrical connection is

required for the kettle heating elements.

For a description of the kettle component of your cooker/mixer, see the separate kettle manual.

Installation & Start-Up

A. INSTALLATION

Your Groen mixer has been test operated at the factory and furnished with all internal wiring, complete

and ready for final connection. A wiring diagram is furnished on the inside of the service panel.

WARNING: INSTALLATION OF THE COOKER/MIXER MUST BE DONE BY PERSONNEL

QUALIFIED TO WORK WITH ELECTRICITY. IMPROPER INSTALLATION CAN

RESULT IN INJURY TO PERSONNEL AND/OR DAMAGE TO EQUIPMENT.

WARNING: ANY MECHANICAL OR ELECTRICAL CHANGE MUST BE APPROVED BY

THE GROEN FOOD SERVICE ENGINEERING DEPARTMENT.

1. Set the cooker/mixer in place and level it. Confirm that there is enough rear wall and overhead

clearance to tilt the mixer safely through its entire tilting range. Provide enough clearance to permit

access for service. Fasten the unit base to the work surface to eliminate any chance that the unit

could tip over.

2. Provide the proper electric power supply as specified on the electrical information plate attached to the

equipment. Observe local codes and/or The National Electrical Code in accordance with ANSI/NFPA

70 - latest edition. The installation should conform to the code that has the more strict requirements.

A standard mixer requires 1 PH, 60 HZ service that provides 8 AMP at 120 V. (See the table of

electrical requirements.) Any electrical service for the kettle requires a separate connection.

ELECTRICAL REQUIREMENTS

120 Volts 240 Volts

1/2 HP motor 7.9 Amps 4.0 Amps

3/4 HP motor 11.5 Amps 5.8 Amps

3. Bring electrical service through the entrance in the back of the control console. Use

waterproof conduit and waterproof connectors.

WARNING: TO PREVENT POSSIBLE ELECTRIC SHOCK, GROUND THE UNIT AT

THE TERMINAL PROVIDED.

4. The following check list may be used to confirm the correctness of the installation.

— 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. START-UP

After the mixer is installed, the installer should confirm that the equipment is operating correctly.

1. At the circuit breaker or fuse box, turn on the electric power supply to the mixer.

2. Tilt the mixer to confirm that it can swing back far enough, so there is no interference when

the kettle is tilted.

3. Make sure that each agitator is properly seated on its drive shaft and that the drive pin is

fully engaged with the coupling.
