INTRODUCTION
How to Use This Manual
1-1
This manual covers the basic areas to help you service the combination
steamerovens.
Before using this manual, you should have knowledge of combination
steameroven operation as described in the Operator Manuals, and a good
understanding of service techniques as presented in the Groen Service School.
It is also recommended that you read and become familiar with the Water
Conditioning section in the Operator Manual. Water quality problems are the most
common cause of steamer failure.
This manual is organized as follows:
Sections CC10-E, CC20-E, CC10-G, CC20-G, C/2-E and C/2G provide
specifications, installation check procedures, a basic theory of operation, electrical
diagrams, and an illustrated parts list for each combination oven.
The SERVICE CODES section is a guide to help you troubleshoot oven problems
when a service code is displayed in the Time display window, or in the Time display
and Cook Temperature display windows.
The TROUBLESHOOTING section guides you through general troubleshooting
procedures for problems that could occur. All possible problems, of course, could
not be listed in this service manual; however, the more common faults are
included.
Voltage, current, and continuity check measurements, component replacement
procedures, and solid-state calibration instructions are located in the
MAINTENANCE section.
The TECHNICAL BULLETINS section should be used to file all of the technical
briefs sent from the factory. When you receive a technical brief, remove the
numbered label from the brief and place it in the appropriate subject area in the
manual; then file the bulletin in numerical sequence in this section. When you
come across the numbered label, go to the technical brief, with the same number,
for additional service information.
The INDEX is an alphabetical listing of the topics covered in this manual, keyed to
the page number where each topic begins.
This non-warranty symbol is used throughout the manual to tell you which repair
actions may not be covered in the equipment warranty.
This service manual should be taken with you on all oven service calls.
Use only Groen Certified Replacement Parts when performing oven repairs.
