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 digital­display 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.

PMA–5/12 AND PMA–5/18 OWNER'S MANUAL 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 [phone] and
ask for the Service Department. Someone there will be glad to assist you.

A. Make sure the Oven has been cleaned, and that all interior parts that may have been removed are

installed correctly and fastened securely. Close the Oven Door securely and make sure all the Door
Partitions operate freely and open fully.

B. Set the Power Switch to the ON position. The interior lights will come on and the Motor Blower

Wheel will rotate in a counter-clockwise direction (as viewed from inside the Oven).

C. Set the Temperature Control to the desired operating temperature (usually 450° to 500°F for pizzas)

and allow the Oven to heat up. Your Oven is ready for use when the Temperature Control Indicator
Light goes out. The Oven should reach its operating temperature in approximately 15-18 minutes;
you can use this time to prepare your product.

D. Enter the baking time into the digital Timer for each Baking Deck (refer to the TIMER

INSTRUCTIONS).
E. Push in and lock down the small Door Lever for the Deck you wish to load.
F. Use a pizza paddle to load your product on that Deck. Release the Door Lever; the Door Partition

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

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.

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.

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

Oven. To decrease

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.

Please call the NU-VU® Service Department for the correct procedures to recalibrate

the temperature inside the Oven carefully rotate the index line on the clear dial

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
must be adjusted IN (or towards

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
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!!!

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

sections) that are cut too short.

tight into the corners. A bulging joint or pucker along the Gasket

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!!!
