Equipment Description

The Groen TA/3 (Figure 1) is an electrically powered, twin shaft scraper mixer, which serves Groen cooker/mixers with capacities of 40 to 80 gallons. The mixer is mounted with a kettle on a common support. To permit easy cleaning of the equipment and emptying of the kettle, a hinge in the back allows the mixer to be tilted out of the kettle.

Model TA/3 has a gearmotor (1 1 -1 /2 or 2 HP at high speed) that drives removable agitators through a transfer case. The stainless steel agitators consist of a primary agitator, which continuously scrapes the bottom and side of the kettle, and a faster, counterrotating, secondary agitator, which operates between the center line and the wall of the kettle.

A control knob turns the three-position selector switch to choose low or high speed operation or to switch the mixer off. For safety, the mixer also has an automatic tilt cutoff switch, which shuts off power to the gearmotor when the mixer is swung up out of the kettle.

Installation of the TA/3 requires connection to 208,240, or 480 V, 3 PH 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

WARNING: ANY MECHANICAL OR ELECTRICAL CHANGE MUST BE APPROVED BY THE GROEN

1. Installation under a ventilation hood or exhaust fan is recommended.

2. 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 legs or base to the floor to eliminate any chance that the unit could tip over.

3. 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.

4. Connect electrical service with waterproof conduit and waterproof connectors.

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

5. 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.

PROVIDED.

B. START-UP

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

1. Make sure the gear case of the gearmotor is filled to the proper level with AGMA #7 oil. The transfer case under the gearmotor is permanently lubricated and needs no additional lubrication.

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

3. Tilt the mixer to confirm that it can swing back far enough and there is no interference when the kettle is tilted.

4. Make sure that each agitator is properly seated on its drive shaft and that the drive pin is fully engaged with the coupling.
