PMA–5/12 AND PMA–5/18 OWNER'S MANUAL
ABOUT YOUR NU–VU® OVEN
ABOUT YOUR NU-VU® OVEN
NU-VU® as a product line has been in existence for over twenty-five 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.
Seminars for both dealers and customers are available either on-site in Menominee, Michigan; at the dealer's
showroom; or on the customer's premises. Technical product information can be generated by customer
requested testing of various products.
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® has combined quality construction, long life components, superior performance, multiple use
operation, and amplified operating procedures to produce the finest equipment available. This means the end
user has the best of ALL worlds.
NU-VU® equipment offers the widest range of options by the use of different air flow systems in conjunction
with heat, moisture, steam and smoke.
NU-VU® AIR OVENS, PROOFERS AND WARMERS:
NU–VU® can provide a wide range of equipment with any of the following features:
•
Bakery Ovens with either INTERNAL or EXTERNAL STEAM generating capabilities. These
Ovens may be equipped with the NU-VU® COOK-N-HOLD option 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 moisture and heat generating units with either manual fill or automatic
humidity systems.
•
General purpose Proofer/Warmers for reconstituting, slow cooking, holding and/or steaming.
NU-VU® MODELS PMA-5/12 AND PMA-5/18:
The Pizza Ovens of the NU-VU® PMA- series are electric and generally do not require ventilation hoods.
However, the ultimate decision as to hood requirements rests with local authorities. NU-VU® has done
operating cost comparisons with gas convection ovens. This data was generated in conjunction with input from
Pacific Gas & Electric.
Based on standard assumptions as to operating conditions for each unit and costs supplied by Pacific Gas &
Electric, the NU-VU® PMA-5/12 and PMA-5/18 Pizza Ovens are comparable in operating cost to like-sized pan
table top gas convection ovens.
The PMA-5/12 and PMA-5/18 Pizza Ovens are specialty products from NU-VU®, and are designed specifically
for the rapid baking of pizzas. The PMA-5/12 measures 26½" wide, 29" deep, and will hold a 12" pizza on each
of its five baking decks. The PMA-5/18 measures 32 ⅝" wide, 36" deep, and will hold an 18" pizza on each of
its five baking decks. Both units stand 34½" high from the base.
Each unit contains a single 550° solid-state Temperature Control to regulate the electric Heat Elements in the
two interior Side Walls. Pizzas are baked on five separate Baking Decks that can be individually accessed
through the partitioned glass Door on the front of the unit. An external compartment contains five digital-
display Timer/Alarms to monitor the baking time for each Baking Deck; these Timers have a recall feature,
which allows you to simply keep repeating the original set baking time.

ABOUT YOUR NU–VU® OVEN
PMA–5/12 AND PMA–5/18 OWNER'S MANUAL
Since the air flow is in a directional pattern the baking times are reduced over conventional deck and tray ovens.
Actual baking times depend upon the Pizza recipe, baking temperature and environmental conditions.
The NU-VU® PMA-5/12 and PMA-5/18 Pizza Ovens are designed for the following:
•
•
•
•
Easy product positioning
Rapid, even baking
Easy cleaning
•
•
•
•
Dependable components
Low energy consumption
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 the NU-VU® manufacturing facility
If contacted, NU-VU® will provide the information on the nearest location. In the event that a customer desires
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 for baking so the customer can determine the suitability for his program.
CONSTRUCTION:
The NU-VU® PMA-5/12 and PMA-5/18 Pizza Ovens are constructed of stainless steel both inside and outside.
All of the frame members are welded to provide long life construction. Components such as temperature
controls, timers, switches, motors, 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.
SHIPMENT:
NU-VU® equipment is 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. from the
NU-VU® manufacturing facility in Menominee, Michigan. Shipping time may vary depending upon the original
shipping point, time of the year, and shipper or shippers used.
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. NU-
VU® works closely with all of its customers in tracing shipments to speed deliveries and minimize handling.

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 carefully 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 damage is found indicate the type and amount of damage
on the shipping documents and notify NU-VU® at (906) 863-4401 immediately after filing a freight
claim.
C. Continue uncrating 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.

OPERATING INSTRUCTIONS
OPERATING INSTRUCTIONS
The NU-VU® PMA-5/12 and PMA-5/18 Pizza Ovens are 5-Deck Ovens ideally suited for
the rapid and continuous production of 12" to 18" pizzas. Each is simple and easy to install
while the front-view glass Door and basic controls make it just as easy to operate. The
unique partitioned Door allows the loading and unloading of each Baking Deck
independently of the others, without opening the entire front of the unit, thereby reducing
temperature fluctuations and eliminating lengthy recovery times.
These simple basic procedures should guide you through the operating process. If you have
any questions, problems or comments please call NU-VU® toll-free at (906) 863-4401 and
ask for the Service Department. Someone there will be glad to assist you.

MAINTENANCE AND CLEANING GUIDE
MAINTENANCE AND CLEANING GUIDE
MAINTENANCE:
NU-VU® equipment is designed to last for years of useful service. Careful consideration is given in selecting
components for durability, performance and ease of maintenance. For example, the Oven Motor has sealed
bearings and never needs to be lubricated. While NU-VU® equipment is designed for minimum care and
maintenance certain steps are required by the user for maximum life and effectiveness:
•
•
•
•
Proper installation of the equipment.
Correct application and usage of the equipment.
Dry-out Procedures performed daily.
Thorough cleaning on a regular basis.
OVEN DRY-OUT PROCEDURE:
A. Wipe up any standing moisture or liquid, both inside and outside of the Oven.
B. Set the Temperature Control and Power Switch to OFF.
C. Leave the Oven Door open about 6" to 8". The residual baking heat will dry out any moisture that
may be trapped in the insulation or other components of the Oven.
D. Leave the Oven Door slightly open while the Oven is not in use.
NOTE: After a day of baking especially heavy or wet products you may find it helpful to run your
Oven at 200° for about 45 minutes to help dry out any excess moisture.
IMPORTANT: THESE DRY–OUT PROCEDURES MUST BE CARRIED OUT DAILY TO
HELP MAINTAIN YOUR EQUIPMENT IN THE BEST POSSIBLE CONDITION. THE
REMOVAL OF ALL RESIDUAL MOISTURE IN THE EQUIPMENT RETARDS ANY
CORROSION OR DETERIORATION OF THE INSULATION AND ELECTRICAL
COMPONENTS AND EXTENDS THE
USEFUL SERVICE LIFE OF YOUR NU-VU® EQUIPMENT!!!

MAINTENANCE AND CLEANING GUIDE
PMA–5/12 AND PMA–5/18 OWNER'S MANUAL
CLEANING:
Your PMA-5/12 or PMA-5/18 should be cleaned at least daily and as soon as possible after a spill has occurred.
It is essential to maintain a clean unit, especially if the public views the unit in your place of business. The
following general guidelines should be used for cleaning:
OVEN INTERIOR - -
•
The Oven Door glass may be cleaned with any good glass-cleaning formula. Be sure to wipe down
the Door Frame, and to clean behind the Door Gasket on the inside of the Oven Door. The Door can
be removed for cleaning heavy soiling by opening the Door until it is perpendicular to the face of the
unit and then lifting the Door straight up off of the Hinge pins.
•
Dried-on debris or heavy soiling can be removed with hot soapy water followed by a rinse with
clean fresh water. Wipe the Door dry before replacing it on the front of the Oven.
CAUTION: Abrasive cleaners may scratch the glass!
•
The Oven interior should be wiped out daily. Remove the Oven Element Cover once a month for
inspection and cleaning:
1) Remove the thumbscrews along the top edge and pull the Element Cover down.
2) Pull the Element Cover out through the front of the Oven to remove it.
•
Inspect the Oven ceiling, the Blower Wheel, the Sidewalls and the Element Cover for mineral
deposits and soiling. Wipe these parts down with hot water and a mild soap, followed by a rinse with
clean fresh water and a mild sanitizing agent. Wiping the interior dry will help to prevent water
spotting. Water spotting and all other mineral deposits should be removed with any mild mineral
removal agent as soon as they are noticeable.
•
•
Replace the Oven Element Cover. Make sure that the Element Cover is pushed all the way back and
up for a tight fit. Secure it in place with the thumbscrews.
The Oven Sidewalls should be removed on an as-needed basis for interior cleaning and mineral
removal. Replace them the same way as the Element Cover, tight to the sides and all the way back.
OVEN EXTERIOR - -

All exterior glass may be cleaned with any good glass-cleaning formula.
The exterior metal surfaces can be cleaned with any good stainless steel cleaner or polish, or with hot
water and a mild soap followed by a thorough rinse with clean fresh water if it is very soiled.
CAUTION: Do not allow any liquids near the Control surfaces!
* * * CAUTION * * *
NU-VU® DOES NOT RECOMMEND the use of any strong commercial or caustic product
on this equipment. DO NOT allow any type of caustic cleaner to come into contact with any
aluminum parts (such as Door frames or Baking Decks), the silicon rubber Door Gaskets, or
any of the sealant in the Oven seams and joints. These types of cleaning compounds may
cause discoloration and degradation of these parts resulting in permanent damage. DO NOT
use bleach or bleach compounds on any chromed parts; bleach may damage chrome plating.
NOTE:
NU-VU® has had very good results with a product called JIFFY CLEANER. For standard
cleaning simply spray JIFFY on and wipe off. Heavily soiled areas may require a short
period of soaking. This cleaner is available through NU-VU® (Part #51-0002) or through
your local Rochester/Midland distributor or representative.

PMA–5/12 AND PMA–5/18 OWNER'S MANUAL
MAINTENANCE AND CLEANING GUIDE
SERVICE AND REPLACEMENT GUIDE
Your PMA-5/12 or PMA-5/18 has been designed to be serviced quickly and easily. In fact, any individual who
has average mechanical ability can do the work. Our Service Department is also available to you Monday
through Friday from 7:00 a.m. to 5:00 p.m. (Central Standard Time) should you find yourself with a situation or
problem other than what is outlined here. Our technicians are also available via pager from 7:00 a.m. to 10:00
p.m. during week-ends and holidays. Call NU-VU® at (906) 863-4401 and ask for our Service Department to
order replacement parts, ask questions, or offer comments.
This SERVICE AND REPLACEMENT GUIDE has been prepared to cover most normal service problems. If
this "trouble-shooting" information does not provide a solution for your particular problem we ask that you call
us for direct assistance. Calling our Service Department before calling in a repair technician can usually save
you both time and unnecessary expense. We want to do everything we can to minimize your "down-time".
You may need to remove an access panel for servicing. DO NOT allow any access panels to drop. When work
on the component is finished replace the panel with care, making sure that all wires are properly placed and not
pulled or pinched. If more than one component is being worked on try to remove only one component at a time.
TEMPERATURE CONTROL, How to Adjust:
A. Place a reliable thermometer (or the thermocouple of a test instrument) on a pan in the center of the
Oven. Turn the unit ON and set the Temperature Control [22] to its normal setting. Allow the
equipment to reach a stable operating temperature.
B. Compare the Temperature Control setting to the reading on the test instrument when the
Temperature Control Indicator Light [23] goes out. If there is a difference of 25° or more you will
most likely need to recalibrate the Temperature Control.
ATTENTION: Please call the NU-VU® Service Department for the correct procedures to recalibrate
your Oven!!!
C. If the difference is more than 5° but less than 25° a simple dial adjustment may solve the problem:
1. Remove the Knob of the Temperature Control by pulling it straight out from the face of the
Control Panel.
2. Hold the black Knob securely with the back of the clear plastic dial toward you. Use a Phillips
screwdriver to loosen the two screws from 3/4 to 1 full turn, but do not remove them!
3. To increase the temperature inside the Oven carefully rotate the index line on the clear dial
clockwise. Each "click" of adjustment is equal to approximately 5° of temperature change in the
Oven. To decrease the inside temperature rotate the clear dial counter-clockwise.
4. Gently tighten the dial screws and install the Knob. Check the Control setting against the test
instrument and repeat this procedure if necessary.
D. If this procedure fails to bring the temperature reading within the desired specs the Temperature
Control or Temperature Control Sensor [6] may need to be replaced.

MAINTENANCE AND CLEANING GUIDE
PMA–5/12 AND PMA–5/18 OWNER'S MANUAL
DOOR LATCH, How to Adjust:
The Door Latch used on the PMA- series Pizza Ovens is preset at the factory during the
original installation. However, should your Door Latch ever need adjustment:
A. Determine if the Oven Door [51] is too loose or too tight.
If it is too loose the Door Latch [53] must be adjusted
OUT (or away from the unit). If it is too tight the Latch
must be adjusted IN (or towards the unit).
B. Loosen the two acorn nuts inside the Latch Cover [54]
with a 3/8" wrench. Pull the Latch Cover straight out from
the Oven Door to remove it and remove the acorn nuts.
C. Open the Door and take careful notice of the adjustment
plate position against the Latch body. Hold the adjustment
plate against the Latch body with one hand while you
loosen the mounting screws with the other hand. Back the
screws out approximately three full turns.
D. CAREFULLY move the Latch body IN or OUT under the
adjustment plate one notch at a time. Make sure the Latch
stays straight up and down and tighten the mounting
screws. Test the Door for proper closing and sealing (refer
to the DOOR TEST PROCEDURE).
E. Repeat steps "C" and "D" if you are not satisfied with the Door adjustment. If the Door tests as
satisfactory make sure the mounting screws are tightened securely.
F. Install the acorn nuts on the ends of the top and bottom Door Latch screws. Turn the nuts on all the
way until they just contact the back side of the Latch mounting bracket, then loosen them by 1½ to 2
full turns. Install the Latch Cover and tighten the acorn nuts lightly to hold the Latch Cover in place.
DOOR GASKET, How to Replace:
Follow these instructions to correctly install your Door Gasket with minimal problems. Use the installation
kit provided. If you have any problems or questions call NU-VU® at (906) 863-4401. Ask for the Service
Department.
A. Remove all pieces of the old Gasket. Thoroughly clean the Door frame in the area of the new
installation. Remove the old sealant and any baked-on deposits.
IMPORTANT: DO NOT DISASSEMBLE THE ACTUAL DOOR FRAME
WHEN REPAIRING OR REPLACING THE DOOR GASKET!!!
B. Pre-cut the replacement Gasket to a size slightly longer than you require.
C. Put a small amount of soap water into and around the slot that the new Gasket will fit into (a small
trigger spray bottle works well). This step is optional but will help in the installation.

PMA–5/12 AND PMA–5/18 OWNER'S MANUAL
MAINTENANCE AND CLEANING GUIDE
D. Position the new Gasket over the slot, allowing the ends to extend past the end of the slot. Press the
mounting flange down into the slot on the Door frame. Use a roller tool to force the mounting flange
into the slot by working the tool back and forth along the Gasket. Make sure the Gasket mounting
flange is completely fitted into the slot and that the Gasket is free to slide back and forth in the slot.
IMPORTANT: DO NOT STRETCH OR PULL ON THE GASKET DURING
THE INSTALLATION PROCESS. THIS WILL LATER CAUSE THE
TRIMMED CORNERS TO SEPARATE AND PULL APART!!!
E. Use a sharp knife or a single-edged razor blade to cut the ends of the Gasket at a 45° angle (you can
use the mitered corner joint on the Door as an angle guide). Cut the Gasket about 1/4" longer than
the required length and work the excess back into the slot. This extra Gasket will help to create a nice
tight corner joint, and allows for any follow-up trimming that may be necessary.
F. Work your way around the entire Door (or the section of the Door having the Gasket replaced).
Make sure the Gasket is just tight into the corners. A bulging joint or pucker along the Gasket
indicates a Gasket section that is cut too long. Joints that pull apart indicate a Gasket section (or
sections) that are cut too short.
IMPORTANT: MAKE SURE THAT THE GASKET AND DOOR FRAME ARE
COMPLETELY CLEAN AND DRY BEFORE APPLYING ANY SEALANT!!!
G. Seal the corner joints after the entire Gasket is properly fitted. Pull the joints apart only enough to put
sealant on all the cut edges only. Allow the Gasket joint to come together. Smooth out any excess
sealant to form a smooth surface on the face of the Gasket. Add more sealant to any spots as
necessary and smooth them down.
H. A quality sealant will be dry to the touch and tack-free in one to two hours after application.
However, it will not be completely cured until six to eight hours later. We recommend that you wait
until after your sealant is completely cured before using your oven.
WARNING: SOME SEALANTS GIVE OFF ACIDIC FUMES AS THEY CURE.
THESE FUMES MAY CAUSE IRRITATION TO THE EYES AND/OR NASAL
PASSAGES. USE CAUTION WHEN OPENING YOUR UNIT AFTER
WAITING FOR ANY FRESH SEALANT TO SET UP AND CURE!!!
