Dear Customer:
Thank you for buying NU-VU®equipment. We think you have purchased one of the best units on
the market today.
Every piece of NU-VU®equipment is put through a full electrical test. In addition, NU-VU®
ovens are randomly selected for test baking to ensure you are receiving the best product possible.
The interior of the oven may darken slightly during this testing process. This coloration is normal
and occurs in any oven that has been operated for a few hours. It will not affect the operation,
durability or warranty of your NU-VU®equipment.
This OWNER'S MANUAL has been put together to give you a good general knowledge of your
equipment. It is not a detailed technical manual; such a book is unnecessary for the daily care and
operation of your unit. However, this Manual does contain some basic trouble-shooting and
service information. If this OWNER'S MANUAL does not answer your questions or solve your
problems, please call us on our toll-free service line at [phone]. You can also FAX your
question or comment to our Service Department at [phone]. You can even e-mail us at
[e-mail]. One of our service technicians will be glad to assist you. Please supply
the model number, serial number and the manufacturing date code of your NU-VU®equipment
when you contact us.
Each page carries information to help you use this OWNER'S MANUAL. The header at the top
of each page contains the title of the section you are currently in. The footer at the bottom of each
page carries the page number, our toll-free telephone number, and our Sales and Service FAX
numbers.
All sections begin at the top of a page and start like this:
