GENERAL

INTRODUCTION

This manual is prepared for the use of trained service technicians and should only be used by those who are properly qualified. This manual is not intended to be all encompassing. You should read, in it's entirety, the repair procedure you wish to perform to determine if you have the necessary tools, instruments and skills required to perform the procedure. Procedures for which you do not have the necessary tools, instruments and skills should not be attempted.

Disconnect the electrical power and follow lockout / tagout procedures

Certain procedures in this manual require electrical test or measurements while power is applied to the machine. Exercise extreme caution at all times when attempting these procedures. Before testing, disconnect electrical power and follow lock/out tagout procedures, then attach test equipment and reapply power to test.

Procedures in this manual will apply to all RRG models unless specified. No procedure in this manual will require the removal or raising of the griddle plate. Pictures and illustrations can be of any model unless the picture or illustration needs to be model specific.

INSTALLATION

Generally, installations are made by the dealer or contracted by the dealer or owner. Detailed installation instructions are included in the Installation and Operation Manual that is sent with each unit. However, it should be noted that an improperly installed unit, especially an unlevel unit can lead to premature electrical component failures. A unit that is higher in the front will cause the flue gases to vent improperly and gather in the front near the electrical components. All RRG models must be installed with an externally mounted regulator.

OPERATION

Detailed operation instructions are included in the Installation & Operation Manual sent with each unit and are also available at WWW.VULCANHART.COM .
