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 at [phone]. You can
also fax your question or comment to our Service Department at [phone] or Toll Free at [phone].
You can even e-mail us at [e-mail]. One of our service technicians will be glad to assist you. Please
remember to supply the model number and serial number of your NU-VU® equipment when you contact us.
When calling for service or parts, try to be at the equipment location so that we can better assist you with your
service or parts needs.

contains the title of the section you are currently in. The footer at the bottom of each page carries the page
number, our telephone number, and our Sales and Service fax numbers.

NVT-3/9 OWNER’S MANUAL ABOUT YOUR SUB-123P

ABOUT YOUR NVT-3/9

The NU-VU® NVT-3/9 is an electrically powered and operated commercial baking/cooking appliance. It does not
require exterior venting under normal circumstances; however, hood and venting requirements vary from country
to country, state to state, and even from locality to locality. For this reason, NU-VU® cannot give specific
detailed information regarding your individual application. Your local building inspector, licensed contractor, or
installer is best qualified to determine your specific needs.

The oven section of the NVT-3/9 features our patented V-AIR® air movement system. A top-mounted blower
moves the air down through the side walls to be heated, then out through specially designed hole patterns to
provide even heat distribution throughout the oven. Your product is baked evenly from top to bottom, side to side,
front to back without turning pans. You can load the oven completely with pans having the same product, bake,
and remove the entire load at the same time. The bake is uniform because each shelf now receives essentially the
same air pattern.

The oven compartment can hold up to three (3) full size 18"x26" (457mm x 660mm) sheet pans, or six (6) half­size 13"x18" (330mm x 457mm) sheet pans on the included stainless steel wire shelves.

The proofer compartment can hold up to nine (9) full size 18"x26" (457mm x 660mm) sheet pans, or eighteen
(18) 13"x18" (330mm x 457mm) half-size sheet pans on the included stainless steel wire shelves. A total of
twelve (12) stainless steel wire shelves are included for use in the oven and proofer.

Measuring 77¾” (1975mm) high, 36½” (927mm) wide and 30 ¾" (781mm) deep, the entire unit takes up less
than 8 square feet (0.75 square meters) of floor space. It is constructed of stainless steel both inside and out. The
front and back frames are cut from single sheets of stainless steel. These frames then are welded to the stainless
base and top headers to form a unit with superior durability and rigidity. Components such as temperature and
humidity controls, timers, switches, motors, heating elements, and others are thoroughly tested before shipment.
Ongoing research and development projects are used to introduce the latest and most dependable components.

The NU-VU® NVT-3/9 is designed for:

• Automatic pan positioning • Dependability

• Rapid and even baking • Low energy consumption

• Easy cleaning • Low maintenance

• Simple operation • Rapid servicing
The AUTOMIST option eliminates the manually filled water pan in the proofer, but requires connection to a

pressurized potable water supply. An adjustable water mist is injected into the blower wheel in the rear of the
proofer. The blower wheel then distributes this water mist evenly throughout the proofer compartment to provide
the controlled humidity necessary for proper proofing action.

IMPORTANT: This appliance is not intended for use by persons (including children)
with reduced physical, sensory or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or instruction concerning use
of the appliance by a person responsible for their safety.

Children should be supervised to ensure that they do not play with the appliance.
