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 DAM AGE TO EQUIPMENT.

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.

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 electr ical 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.

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.
