AMP–12 & AMP–18 OWNER'S MANUAL ABOUT YOUR NU–VU® EQUIPMENT

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 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 the 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. Technical product information can be generated by customer-requested
testing of various products and equipment.

NU–VU® has, over a period of time, developed a series of Ovens, Proofers, Smokers,
Steamers and Warmers designed to provide maximum performance with minimum energy
requirements and care by the operator. NU–VU® has combined quality construction, long-life
components, superior performance, multiple use operation and amplified operating instructions
and procedures to produce the finest equipment available. This means the end user has the best
of ALL worlds.

AMP–12 AND AMP–18 ROLL–IN PROOFERS:

The NU–VU® AMP–12 and AMP–18 Proofers are single-compartment high capacity
Proofers. The AMP–12 measures 77½" high, 32" wide, and 37_" deep, and accomodates a
separate roll-in rack holding up to twelve full-size 18" x 26" baking pans. The AMP–18
measures 89" high, 35_" wide, and 37_" deep, and will accomodate a separate roll-in rack
holding up to eighteen full-size 18" x 26" baking pans.

Each Proofer is available in 120 volt, 208 volt or 240 volt single phase configurations (the 120
volt model comes equipped with a power cord and plug). A single water hook-up in the rear of
the unit continuously supplies NU–VU®'s AUTOMIST® automatic humidity system,
eliminating the constant checking of water levels and ensuring that your Proofer will never "run
dry". Simply set the automatic AUTOMIST® controls and the Proofer takes care of
everything else.

NU–VU® offers the AMP–12 and AMP–18 with a positive air-flow system. Previously, one
of the problems associated with circulating air proofers was their inability to proof dough
products evenly and consistently without turning the pans or selectively removing them at
various times during the proofing cycle. NU–VU®'s air-flow system enables the user to load
the Proofer completely, with pans having the same product, and be able to remove all the pans
at the same time with a proof that is consistent throughout the load.

ABOUT YOUR NU–VU® EQUIPMENT AMP–12 & AMP–18 OWNER'S MANUAL

This is possible because the air is directed in at each shelf location through holes in the Proofer
sidewalls. Because each pan receives essentially the same air flow the proof is even and
uniform. In other proofers the air may be blown around randomly and thus different pans will
have different conditions and results.

Each unit is constructed of stainless steel both inside and outside. An insulated stainless steel
Door on self-closing Hinges and fitted with a magnetic vinyl Gasket helps maintain the required
proofing conditions. A stainless steel Cart Ramp eases the transfer of loaded product racks into
and out of the Proofer.

The AMP–12 and AMP–18 Roll–In Proofers are designed for the following:

• Automatic pan positioning • Dependable components

• Rapid, even proofing • Low energy consumption

• Easy cleaning • Low maintenance

• Simple operation • Rapid servicing

AVAILABILITY AND TESTING:

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

• At a dealer's showroom.

• At an existing installation.

• At NU–VU®'s manufacturing plant.
If contacted NU–VU® will provide information on the nearest location. In the event that a

customer wants to test a unit at his place of business arrangements can be made based on a
specifically defined program. In the event that a customer wants to try a special product,
arrangements can be made to determine what conditions are necessary so the customer can
determine the suitability of the unit for his program.

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 of its designated
representatives present during the test. All results of any such comparison testing shall be made
available to NU–VU® and may be used by NU–VU®.

CONSTRUCTION:

The AMP–12 and AMP–18 are each constructed of polished stainless steel inside and out. All
of the frame members are welded to provide long-life construction. All components such as
temperature and humidity controls, timers, motors, switches, heating elements and others are
thoroughly tested before shipment. On-going research and development projects are used to
introduce the latest and most dependable parts.

and shipper or shippers used. NU–VU® works closely with all of its customers in tracing
shipments to speed deliveries 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 negligent
handling. For this reason it is necessary for the receiving party to immediately do a thorough
inspection of the equipment when it arrives.

AMP–12 & AMP–18 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, negligent handling can sometimes
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 determine if the unit is damaged. 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 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. Make sure the Door closes completely, and that the Door

Gasket seals firmly (refer to the DOOR TEST PROCEDURE in the SERVICE AND

REPLACEMENT GUIDE). If the Gasket does not seal correctly please contact NU–

VU®'s Service Department for instructions and assistance in any required

adjustments.

RECEIPT AND INSTALLATION AMP–12 & AMP–18 OWNER'S MANUAL

Position the unit where it is to be operated. 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 and/or phase is not the same call NU–VU® for instructions on changing the
voltage and/or phase of your equipment.

Attach the Cart Ramp [36] to the threshold of the Proofer. The Door should still close and
latch easily with the Cart Ramp in place.

Connect your unit according to all national and local electrical codes, either through a plug­type connection or direct wiring. All connections must be made with COPPER WIRE ONLY in
the correct gauge for the application. Provide enough slack in the wiring to allow for
equipment to be moved about during installation and servicing.

IMPORTANT: DO NOT CONNECT THIS UNIT IF YOUR POWER SOURCE

DOES NOT COINCIDE WITH THE UNIT LABEL!!!

FOR 120 VOLT CORDED UNITS - -

IMPORTANT: ALL POWER SHOULD BE TURNED OFF AT THE WALL

BREAKER WHILE THE UNIT IS BEING CONNECTED!!!

Connect the unit with the attached three-prong 120 volt/20 amp Power Cord to a 120 volt/20
amp grounded receptacle (NEMA 5-20R or equivalent). The three-prong grounding plug must
be plugged directly into a properly grounded three-prong receptacle capable of carrying 20
amps (17 amps nominal), and the grounding prong must never be cut off or otherwise removed
from the plug.

Allow enough slack in the cord to allow the equipment to be moved about during the
installation and any future required maintenance or service work.

FOR 208/240 VOLT UNCORDED UNITS - -

The customer or installing electrician must supply a flexible power cord to connect the AMP–
12 or AMP–18 to the available power supply. This connection must be made in accordance
with all local, state and national electrical codes, and be capable of carrying a nominal 17-amp
current load.

Your electrician or licensed installer should remove the Outside Top [38] of the unit to expose
the Power Terminal Block [1]. A wiring schematic for this unit is attached to the inside of the
unit near the power terminal connections.

The following steps should be carefully observed:
A. Take note of the labeling on the Oven terminal connections (Line 1, Line 2, Neutral)

at the Power Block [1].

B. Carefully identify the power source connections and attach them to the appropriate

terminals. Make sure all connections are clean and tight.

C. 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.

#2 - Power Connection

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

the main power supply.
E. Check the voltage at the Power Block connections with a voltmeter to confirm

conformity with the unit's electrical requirements as posted on the side of the unit. If

all voltage readings are correct the unit is ready for its INITIAL START–UP. If the

readings DO NOT coincide you must call NU–VU®'s Service Department for

instructions on changing the voltage and/or the phase of your equipment or power

source.
F. Replace the Outside Top of the unit. Be careful not to pull or pinch any wires while

installing this panel.
G. Complete the installation of the water supply to the unit (refer to INSTALLATION

OF WATER SUPPLY immediately following). Attach any required drain plumbing to

the fixture at the bottom rear of the unit.

INSTALLATION OF WATER SUPPLY:

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 water filter may be
installed at the water source or adjacent to the Water Inlet Fitting on the rear of the Proofer,
whichever is more convenient for you.
A. Run the correct size tubing from the water supply to the Proofer location; this tubing

should be at least as big as the Water Inlet Fitting [37] on the rear of the Proofer.

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.
