ABOUT YOUR NU–VU® EQUIPMENT

NU–VU® as a product line has been in existence for over twenty-one years. Its units are in use
throughout the United States and Canada and have been exported to other parts of the world.
NU–VU® continually modifies and updates its equipment to improve the capabilities as new
innovations become available. This enables the user to obtain better and more useful results.
NU–VU® currently manufactures an entire line of food service equipment in Menominee,
Michigan. All of the equipment is tested under anticipated operating conditions prior to
shipment.

Any prospective customer is invited to try different food products in the newly completed test
kitchen in Menominee, Michigan. Seminars for both dealers and customers are available: on­site in Menominee, Michigan; at a dealer's showroom; on the customer's premises. If contacted
NU–VU® will provide information on the nearest location and availability. In the event that a
customer wants to try a specific product arrangements can be made to determine what
conditions are necessary for baking so that the customer can determine the suitability for his or
her program.

NU–VU® can provide a wide range of equipment with the following features:

• Bakery Ovens with either INTERNAL or EXTERNAL STEAM generating
capabilities. These Ovens may be equipped with COOK–N–HOLD capabilities for
broader use.

• COOK–N–HOLD Ovens for either high temperature or low temperature operation
with moisture and smoking capabilities.

• Low temperature Ovens with moisture and smoking capabilities.

• Steamer Ovens with high and low temperature capabilities.

• Multi–Ovens that dry bake, steam, and bake with steam.

• Bakery Proofer/Warmers with heat and moisture generating units with either manual
water fill or automatic humidity systems.

• General purpose Proofer/Warmer for reconstituting, slow cooking, holding and/or
steaming.

NU–VU® has, over a period of time, developed a series of Ovens, Proofers, Steamers,
Smokers and Warmers designed to provide maximum performance with minimum energy
requirements and care by the operator. NU–VU® Food Service Systems offers the widest
range and variety of equipment through the varied use of heat, moisture, steam and smoke
options.

ABOUT YOUR NU–VU® EQUIPMENT PRO–8 & PRO–16 OWNER'S MANUAL

The NU–VU® PRO–16 Proofer is a double-door floor unit equipped with locking casters.
Designed vertically to minimize floor space, it has a capacity of up to 16 full size 18"x26" sheet
pans. The PRO–16 measures approximately 69" high (including the locking casters), 25" wide
and 31" deep (plus 3½" for the door and latch).

The PRO–16 is also available in a wider version (model PRO–16X). This model measures 69"
high, 31" deep (plus Door and Latch), and 28½" wide.

These models provide maximum proofing and warming capabilities in units that are extremely
small, making their six square feet of your floor or counter an economical space-saving
investment.

These reach-in Proofers are powered by a 120 VAC electrical supply, and come equipped with
a cord and plug for connection to a dedicated 120 volt service rated for 20 amps. The PRO–8
operates at a nominal current load of 16 amps; the PRO–16 draws a nominal 19 amp load.

Standard units are constructed with a stainless steel exterior and aluminum interior, and
equipped with a manually-filled water reservoir to provide controlled humidity levels during
proofing and warming operations. Both are equipped with individual humidity and 110F
temperature controls, along with a bottom-mounted blower wheel for continuous air flow over
and around your product. All controls are centrally located on the bottom front of the unit for
ease of operation. A complete insulation package allows these units to perform at top
efficiencies.

Each is also available with the following options:

• AUTOMIST Humidity System - - eliminates the need for a manually-filled water pan,
and automatically provides even and continuous humidity levels throughout your
proofing process (PROW- models).

• Warmer - - supplied with a 250F thermostat to reach and maintain optimum product
warming or holding temperatures.

• Stainless Steel interior - - used in place of aluminum for extended durability and
increased ease of cleaning.

The NU–VU® PRO–8 and PRO–16 Proofers are designed with these features in mind:

• Automatic pan positioning • Dependable components

• Rapid, even production • Low energy consumption

• Easy cleaning • Low maintenance

• Simple operation • Rapid servicing

The NU–VU® PRO–8 and PRO–16 can be used to proof almost any product. A sampling of
these products might include:

• Breads • Pizza crusts

• Rolls • Croissants

• Pastries • Raised Donuts

When equipped with the Warmer option either unit can be used to reheat product portions, or
to hold a variety of finished products at a safe and convenient temperature for use at a later
time. These products can include, but are not limited to:

• Baked goods • Casseroles

• Vegetables • Individual serving portions

• Pizza • Meats

CONSTRUCTION:

The NU–VU® PRO–8 and PRO–16 Proofers are constructed of stainless steel outside and
polished aluminum inside. An optional stainless steel interior is also available. All of the frame
members are formed and welded to provide durability, rigidity and long life construction.
Components such as temperature and humidity controls, 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.

COMPARISON WITH OTHER UNITS:

NU–VU® will provide test data or a test unit for the comparison of results with any other unit
on the market; however, NU–VU® reserves the right to have one or more of its designated
representatives present during the test. All results of such comparison testing shall be made
available to NU–VU® and may be used by NU–VU®.

AVAILABILITY AND TESTING:

A prospective customer may see a unit in operation as follows:

• At a dealer's showroom,

• At an existing installation,

• At the NU–VU® manufacturing facility.
If contacted, NU–VU® will provide information on the nearest location and equipment

availability. In the event that a customer wants to try a specific product arrangements can be
made to determine what conditions are necessary for baking so that the customer can
determine the suitability for his or her program. Technical product information can be
generated by customer-requested testing of various products and equipment.

SHIPMENT:

NU–VU® equipment is usually shipped directly from the factory or delivered from a dealer,
unless sold at a show or after a test or demonstration. Unless otherwise agreed to by NU–VU®
freight is paid by the buyer F.O.B. the NU–VU® facility in Menominee, Michigan. Shipping
time may vary depending upon the original shipping point, time of year and shipper/shippers
used.

NU–VU® works closely with all of its customers in tracing shipments to speed delivery and
minimize handling. NU–VU® employs the latest accepted packaging standards to ensure that
your equipment arrives in excellent condition. However, damage may still occur due to
accident or mishandling by the freight company. For this reason it is necessary for the receiving
party to immediately do a thorough inspection of the equipment when it arrives.

PRO–8 & PRO–16 OWNER'S MANUAL RECEIPT AND INSTALLATION

RECEIPT AND INSTALLATION

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, accidents and/or negligent
handling can still 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 packing damage is found uncrate the unit immediately in the presence of the

delivery person to determine if the unit is damaged. If any equipment 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, back, and both sides) for any

visible or hidden damage.

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

casters) for any damage.

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

company and NU–VU® Food Service Systems.

F. Check the Proofer Door(s). Make sure the Door is square to the front of the unit,

opens and closes easily, and seals completely. If the Door does not fit or operate
correctly please contact the NU–VU® Service Department for instructions and
assistance in any adjustments that may be necessary.

INSTALLATION:

ELECTRICAL CONNECTIONS - -

A. Check to determine that the power source is the same voltage and phase as that

required by the unit. The electrical requirements for the PRO–8 or PRO–16 are listed
on a grey metallic label affixed to the side of the unit.

B. Move the unit to the area where it will be used. Lift and carry the PRO–8 carefully. If

your unit is equipped with casters simply roll it into position. Do not allow the
door(s) to swing open.

C. For the PRO–8, attach the included 4" appliance legs to the outside corners of the

base and position the unit carefully. Install the PRO–8 or PRO–16 so that it stands
solid and level (adjust the legs or shim the casters as necessary).

D. Carefully set all Controls and Switches to the OFF position.

E. Connect your unit with the attached 120 volt/20 amp power cord [1] to a 120 volt/20

amp receptacle (NEMA 5-20R or the equivalent). Allow enough slack in the power
cord to allow the equipment to be moved about during the installation and any future
required maintenance or service.

RECEIPT AND INSTALLATION PRO–8 & PRO–16 OWNER'S MANUAL

WATER CONNECTION (AUTOMIST UNITS ONLY) - -

IMPORTANT: NU–VU® strongly recommends that SOFT WATER only be used in any unit
requiring a water supply. Also, a good quality water filter MUST be installed in-line between
the unit connection and the water supply to guard against clogging and mineral build-up in the
components. This is extremely important in areas having hard water.

This equipment is to be installed to comply with the applicable federal, state and local
plumbing codes having jurisdiction.

Please follow these procedures to help ensure a proper water connection:
A. Run any flexible ¼" OD tubing suitable for use with potable water from the water

supply line to the Proofer location. Allow some slack for final unit positioning and
service. Avoid any kinks or strains on the tubing and place the tubing where it will not
be damaged in any way.

B. The tubing end that attaches to the Proofer must not be damaged or deformed in any

way. The cut end should be cut straight and clean with no deforming of the tubing.
All burrs and sharp edges should be removed to ensure a proper and leak-free
connection.

C. Position the tubing so that the tubing runs straight into the intake fitting. Be careful

not to kink the tubing if you bend it, and do not bend the tubing within two (2) inches
of the end.

D. The two-part compression fitting (tapered collar and nut) is placed approximately 1"

onto the tubing so that the collar is inside of the nut and the threaded opening of the
nut is toward the intake fitting.

E. Push the tubing all the way into the intake fitting (approximately ¼") and hold it there

while you thread the compression nut onto the intake fitting. Tighten the compression
nut with an open-end wrench, but do not over–tighten! If the joint leaks when tested
and further gentle tightening does not stop the leak the two-part compression fitting
must be replaced.

Careful attention to these simple procedures will help to ensure an installation without leaks. If
you have any questions or problems please call the NU–VU® Service Department at (800)
338-9886.

INITIAL START–UP - -

A. Set the power switch [11] to the ON position. The blower wheel [21] in the bottom

of the Proofer should begin to rotate in a counter-clockwise direction.

B. STANDARD MANUAL FILL - -

1. Open the Proofer door [31] and remove the Water Pan [25]. Set the Humidity

Control [12] to #5 or #6. The Humidity Control Indicator Light [13] should
illuminate and the humidity element [3] will begin to heat up.

2. Fill the water pan with approximately 2" of water and place it on the humidity

element. Place a reliable thermometer on a shelf in the middle of the Proofer and
close the Door. The water should begin to heat up and in a few minutes a light
fogging should begin to form on the door glass.
