Dear Customer:

IMPORTANT: THESE SHADED BOXES WILL CONTAIN IMPORTANT WARNING,

OPERATING AND/OR SAFETY INFORMATION!

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]. 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, 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 telephone number, and our Sales and Service fax numbers.

SUB-123P OWNER’S MANUAL ABOUT YOUR SUB-123P

ABOUT YOUR SUB-123P

The NU-VU® SUB-123P 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 SUB-123P 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" sheet pans, or six (6) half-size 13"x18"
sheet pans on the included chrome-plated wire shelves.

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

Measuring 77¾” high, 36½” wide and 28 5/8” deep, the entire unit takes up less than 7½ square feet 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® SUB-123P 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 bottom
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.

SUB–123P OWNER'S MANUAL RECEIPT, INSTALLATION AND START-UP

Fig. #1 - Installation

RECEIPT, INSTALLATION AND START-UP

RECEIPT:

It is essential to inspect the unit immediately when it arrives. NU-VU® has placed instructions on the
packaging to help avoid damage in transit. However, negligent handling can produce hidden damage.

These steps should be followed:

A. Inspect the entire perimeter of the package for damage or punctures to the packing material.

This may indicate damage to the unit inside. Call any and all packing damage to the attention of
the delivery person.

B. If any package damage is found uncrate the unit immediately in the presence of the delivery

person to determine if the unit is damaged. Pay special attention to the top of the unit. Make sure
it is not bent or otherwise damaged, which may occur if the top of the unit has struck a door frame
or the top of a trailer. If any damage is found indicate the type and amount of damage on the
shipping documents and notify NU-VU® at [phone] immediately after filing a freight
claim.

C. Uncrate the unit carefully and check the entire unit (top, front, back, and both sides) for any

visible or hidden damage.

D. Remove the unit from the shipping pallet and inspect the bottom (including the Casters) for any

damage. Check the Casters and the Proofer Motor/Cover under the unit.

E. If any damage is noted after the driver leaves immediately contact the freight company and

NU-VU® Food Service Systems.

F. Check the Oven and Proofer Doors. Make sure both Doors close completely, and that the Door

Gaskets seal firmly (refer to the DOOR TEST PROCEDURE in the SERVICE AND
REPLACEMENT GUIDE). If they do not close or seal properly please contact the NU-VU®
Service Department for instructions and assistance in any required adjustments.

G. Count the number of Shelves included. There should be a total of twelve (12) Shelves (nine for

the Proofer, three for the Oven). Contact NU-VU® immediately concerning any shortage.

RECEIPT, INSTALLATION AND START-UP SUB-123P OWNER’S MANUAL

IMPORTANT: DO NOT CONNECT THIS UNIT IF YOUR POWER SOURCE DOES NOT

MATCH THE REQUIREMENTS AS LISTED ON THE UNIT LABEL!

WARNING: ALL POWER MUST BE TURNED OFF AT THE ELECTRICAL SUPPLY WHILE

THIS UNIT IS BEING CONNECTED!

IMPORTANT: IN A THREE PHASE SYSTEM ANY WILD LEG (MORE THAN 120 VOLTS

TO NEUTRAL) MUST ALWAYS BE CONNECTED TO L-2!

INSTALLATION:

Record the Model Number and complete Serial Number of your unit in the spaces provided on page 27 of
this manual. You will need these numbers if you should ever need to contact our Service Department
concerning adjustments, replacement parts or other service needs.

Roll the unit into the exact position where it is to be operated. Make sure there will be enough clearance on
each side of the unit for proper cooling during operation, and for ease of access during maintenance or
service. NU-VU® recommends a minimum clearance of 4" at the back and both sides of the unit. Mark the
locations of the electrical and optional water connections on the wall.

Check the swing of both the Oven and Proofer Doors, making sure they have enough room to open
completely without hitting anything or obstructing the work area.

Move the unit out from its operating position and proceed with the service connections.

Connection of Electrical Supply - -

Check to determine that the power source is the same voltage and phase as that indicated on the label on the
side of the unit. If the voltage or phase is not the same, please call NU-VU® service department at (906)
863-4401.

This equipment must be installed and connected in accordance with all applicable federal, state, province,
and/or local electrical codes having jurisdiction. All electrical connections must be made with COPPER
WIRE ONLY in the correct gauge for the application. The unit may be connected either through a plug and
receptacle-type connection or direct wiring. Allow enough slack in the wiring to allow for equipment to be
moved during installation or any required maintenance and servicing.

The electrician should remove the Outside Top [71] to expose the power supply connections at the Power
Terminal Block [1] on top of the oven compartment. A wiring schematic is attached to the wiring near
the power terminal connections.

Proper electrical connections will vary depending on the voltage, phase and frequency requirements of the
unit and available power supply. The following instructions are for the most common 120/208 volt or
120/240 volt configurations (refer to Fig. #2 on page 5), and may be modified to fit your installation.
A. The electrician must install a cable clamping device or cord restraint in the rear access hole. This

cable clamping device must be firmly attached to the unit, and appropriately sized for the power
supply wire or cord being used.

B. Take note of the labeling on the Oven terminal connections (Line 1, Line 2, Line 3, and Neutral)

at the Power Terminal Block [1].

C. Carefully identify the power source connections and attach them to the appropriate terminals. Make sure

all connections are clean and tight.

D. Be sure the unit is properly grounded BEFORE use by attaching a grounding wire to the Ground

Lug [2] next to the Power Terminal Block.
