RECEIPT AND INSTALLATION XO–1M OWNER'S MANUAL

INSTALLATION PROCEDURES:

Attach the Appliance Legs to the base of the unit if your Oven will sit on a table or counter.
Legs are not necessary if the unit is to be fastened and sealed to the table or counter surface.
Move the unit into the position 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 or power supply.

The NU–VU® XO–1M is normally equipped for 208 volt or 240 volt operation in single phase
configurations.

IMPORTANT: DO NOT ATTACH UNIT IF THE POWER SOURCE DOES NOT
COINCIDE WITH THE UNIT LABEL!!!

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 the initial installation, the connection of any optional
water supply, and any future maintenance or required service work.

Your qualified installer or electrician should remove the Side Access Panel of the unit to
expose the Power Terminal Block connections. A copy of the unit's wiring schematic is
attached to the inside of the unit near the power terminal connections.

IMPORTANT: ALL POWER SHOULD BE TURNED OFF AT THE WALL

BREAKER WHILE THE UNIT IS BEING CONNECTED!!!

XO–1M OWNER'S MANUAL RECEIPT AND INSTALLATION

Refer to the illustration of the Power Terminal Block connections on page 8 and carefully
follow these steps to safely complete the electrical portion of the Installation Procedure:
A. Take note of the labeling on the terminal connections (Line 1, Line 2) at the Power

Terminal Block.

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 next to the Power Terminal Block.

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 connections on the Power Terminal Block with a voltmeter

to confirm conformity with the unit label requirements. If all readings are correct you
may proceed with the connection of the optional water supply (if required) followed
by the INITIAL START–UP. If the readings DO NOT coincide with the unit
requirements you must call NU–VU®'s Service Department for instructions on
changing the voltage and/or phase of your equipment or power source.

F. Replace the Side Access Panel on the unit. Be careful not to pull or pinch any wires

while installing the Panel (replace the Side Access Panel only if you do not intend to
do the INITIAL START–UP immediately).

G. Complete the installation of the optional water supply to the unit (refer to

INSTALLATION OF WATER SUPPLY immediately following).

H. Position the unit in it's place of operation and adjust the Appliance Legs (if so

equipped) so that the unit sits firm and level.

INSTALLATION OF OPTIONAL WATER SUPPLY:

IMPORTANT: FAILURE TO FOLLOW THESE INSTRUCTIONS OR
IMPROPER INSTALLATION MAY CAUSE SEVERE EQUIPMENT DAMAGE
OR EVEN PERSONAL INJURY, AND MAY ALSO VOID ALL OR PART OF
YOUR NU–VU® EQUIPMENT WARRANTY!!!

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 build­up in the components. This is extremely important in areas having hard water. The filter may be
installed at the water source or adjacent to the Water Inlet Fitting on the rear of the unit,
whichever is more convenient for you.

IMPORTANT: THIS UNIT NEEDS TO BE INSTALLED WITH ADEQUATE BACKFLOW
PROTECTION TO COMPLY WITH APPLICABLE FEDERAL, STATE AND LOCAL CODES.

RECEIPT AND INSTALLATION XO–1M OWNER'S MANUAL

IMPORTANT: THIS UNIT REQUIRES A SCREEN OF AT LEAST 100 MESH TO BE
INSTALLED IMMEDIATELY UPSTREAM OF ALL CHECK VALVE TYPE BACKFLOW
PREVENTERS USED FOR WATER SUPPLY PROTECTION. THE SCREEN SHALL BE
ACCESSIBLE AND REMOVABLE FOR CLEANING OR REPLACEMENT.

Please follow these steps to connect an optional water supply to your unit:
A. Run ¼" tubing from the water supply line to the unit 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 unit 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 fit and leak-free
connection.

C. Position the tubing so that the tubing runs straight into the Water 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 Water Intake Fitting.

E. Push the tubing all the way into the Water Intake Fitting (approximately ¼") and hold

it there while you thread the compression nut onto the Water Intake Fitting. Tighten
the compression nut with a ½" open-end wrench, but do not over–tighten the fitting!
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 NU–VU®'s Service Department at (906) 863-

4401.

* OPERATING INSTRUCTIONS *

XO–1M:

Your XO–1M is equipped with an optional Motor Reversing Switch. There are three (2)
positions for this Switch:
HI Motor/Blower Wheel rotation is counter-clockwise, air velocity and delivery volume

are at the highest level.

LO Motor/Blower Wheel rotation is clockwise, air velocity and delivery volume are at the

lowest level.

The Blower Wheel is designed to give different air velocities as the rotation direction is
changed. The HI setting will give the highest velocity of heated air while the LO setting will
deliver less air at a lower velocity. Different air speeds may be used for different products.
Generally speaking the HI setting will be used for dough products such as breads, rolls,
croissants, Danish, etc., while the LO setting may be used for cookies, delicate cakes and
batter products such as muffins, and for slow-cooking and roasting of meats. Only you can
determine the best air flow setting for your desired end results.

WARNING: NEVER CHANGE THE MOTOR REVERSING SWITCH FROM HI
TO LO, OR FROM LO TO HI, WHILE THE OVEN MOTOR IS STILL
TURNING!!! DOING SO MAY DAMAGE THE POWER SWITCH, THE OVEN
MOTOR OR THE MOTOR REVERSING SWITCH!!!

Follow these general instructions for proper baking results. These general instructions are for

XO–1M OWNER'S MANUAL OPERATING INSTRUCTIONS

NOTE: At the beginning of each day you may want to pre-heat your Oven 25

higher than the required baking temperature. Since your Oven requires time to
reach the proper operating temperature you should plan ahead so your Oven and
product are ready at the same time. When the desired temperature is reached
(approximately 15-20 minutes after start-up) the Oven Temperature Control
Indicator Light will go out. It is not necessary to reset to pre-heat temperature with
each load unless you are baking new items at a much higher temperature.

C. Load your Oven carefully. Center the pans

between the rear of the Oven and the Door.
Keep the Oven Door CLOSED unless loading
or unloading product to maintain Oven
temperature and minimize energy usage.

NOTE: The 5-pan Side Rack is designed to hold

five (5) half-size pans or five (5) food service
pans. Load the food service pans on every other
pan support starting with the top bar. Load the
half-size pans on every other pan support
starting with the second bar from the top.

D. Set the Oven Timer or program for the estimated

baking time less one to two minutes. This will
assure an indication from the Buzzer Alarm prior
to the actual end of the baking time and help
prevent over-baking.

E. As soon as the product is finished open the Oven

Door and remove the product quickly.
Immediately close the Oven Door to minimize
temperature loss.

F. You may bake several different items at the same time and temperature, but each

individual pan should have the same type of product on it and be panned in the same
manner.

CAUTION: STAND AWAY FROM THE FRONT OF THE OVEN WHEN
OPENING THE OVEN DOOR AFTER A COOKING CYCLE TO AVOID

EXPOSURE TO ESCAPING HEAT AND STEAM!!!

G. Whenever the baking is completed for the day, or for an extended period, the Oven

Temperature Control should be turned to the OFF position and the Power Switch
set to OFF (refer to the Daily Dry-Out Procedure for the Oven in the
MAINTENANCE AND CLEANING GUIDE).

INTERNAL STEAM INJECTION:

This XO–1M option uses a manually-operated Steam Switch to activate the Water Solenoid
Valve and spray a fine 12 to 15 second water mist through the Water Injection Nozzles into the
heated Oven chamber. This water mist flashes into steam and is circulated through-out the

NU–VU® FOOD SERVICE SYSTEMS MENOMINEE, MICHIGAN 49858
[phone] SALES FAX [phone] • SERVICE FAX [phone] page 17

OPERATING INSTRUCTIONS XO–1M OWNER'S MANUAL

Oven cavity by the Blower Wheel.
To operate the INTERNAL STEAM INJECTION:

A. Increase the setting on the Temperature Control just enough so that the Temperature

Control Indicator Light comes on.

B. Press and release the spring-loaded Steam Switch to begin a water spray in the Oven.

The Solenoid Water Valve will open allowing water to spray through the Injector
Nozzles and into the Oven chamber where it flashes into steam. The spray will stop
automatically after 12 to 15 seconds. The air in the Oven is saturated when small
water droplets appear on the Oven floor.

C. Additional steam injections can be used later in the baking cycle for breads and rolls

as long as the Temperature Control Indicator Light is illuminated.

The following chart may be used as a general baking guide:

Product Time (in minutes) Temperature (F)

Croissants 11 335
Hot Dog Buns 8 – 10 345
Hamburger Buns 10 – 11 345
1 lb. White Bread 22 – 25 350– 360
French Bread 22 – 25 350– 360
Submarine Rolls 14 – 15 350– 360
Cookies 9 – 10 290– 300
Pizza — Deep Dish 9 500
— Regular 5 – 6 500

It will be necessary for you to do some testing to determine your final conditions since your
recipes may vary and your desired product appearance is one of choice.

* 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 NU­VU® 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. Set the Oven Temperature Control and Oven Power Switch , or Programmable

Control and Power Switch, to OFF.

B. 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.

C. Leave the Oven Door open about 1 to 2 inches while the Oven is not in use.

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 LIFETIME OF YOUR NU–VU® EQUIPMENT!!!

XO–1M OWNER'S MANUAL SERVICE AND REPLACEMENT GUIDE

CLEANING:

Your XO–1M should be cleaned 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 should be used for cleaning:

DOOR - -

• 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: Do not use abrasive cleaners on the Door or you may scratch the Door

Glass!!!

INTERIOR - -

• The Oven interior (including the Door Jamb) should be wiped out daily. Remove the

Oven Element Cover once a month for inspection and cleaning (if you have the
INTERNAL STEAM option you should remove, inspect and clean the Element
Cover weekly):

 Remove the four thumbscrews holding the Right Side Rack and the Element

Cover in place.

 Mark the top of the Side Rack and pull it and the Element Cover out the front of

the Oven.

• Inspect the Oven ceiling, the Blower Wheel, the Sidewall and the Element Cover for

mineral deposits. 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 any other mineral deposits should
be removed with any mild mineral removal agent as soon as they are noticeable.

• Replace the Oven Element Cover and Side Rack; make sure the top of the Side Rack

is up or your pans may sit crooked in the Oven. Secure them in place with the
thumbscrews.

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 water near the Control surfaces!!!

XO–1M OWNER'S MANUAL SERVICE AND REPLACEMENT GUIDE

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 [23] 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 [24] goes out. If there is a difference of
more than 25 you may need to recalibrate the Temperature Control. Please call NU–
VU®'s Service Department at [phone] for the proper calibration procedures
before attempting to calibrate the Oven!

C. If the difference is 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 Access Panel [59].

2. On the back of the Knob you will see two screws. Use a phillips screwdriver to

loosen these screws from ¾ to 1 full turn, but do not remove them!

3. Hold the black Knob securely with the back of the clear plastic dial toward you.

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 will have to be replaced.

DOOR LATCH, How to Adjust:

Determine if the Oven Door is fitting too loose (it will leak steam and hot air past the

Gasket) or too tight (it will not close properly, or will "pop" open unexpectedly). If it is

too loose the Door Latch must be adjusted OUT (away from the unit); if it is too tight the

Door Latch must be adjusted IN (towards the unit). Please proceed as follows:

NU–VU® FOOD SERVICE SYSTEMS MENOMINEE, MICHIGAN 49858
[phone] SALES FAX [phone] • SERVICE FAX [phone] page 23

SERVICE AND REPLACEMENT GUIDE XO–1M OWNER'S MANUAL

A. Loosen the two acorn nuts inside the

Latch Cover with a _" wrench. Pull
the Latch Cover straight out from
the Door to remove it and then
remove the acorn nuts.

B. Open the Door and take careful

notice of the adjustment plate
position against the body of the Door
Latch.

C. Hold the adjustment plate against the

body of the Door Latch with one
hand while you loosen the three
mounting screws with the other
hand. Back the screws out
approximately three full turns.

D. CAREFULLY move the Door Latch

body IN or OUT under the
adjustment plate one notch at a time.
Make sure the Door 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 outlined in this
section).

E. Repeat steps "C" and "D" if you are not satisfied with the Door adjustment. If the

Door tests as satisfactory make sure the three 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 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 TEST PROCEDURE:

A. Cut one or two strips of paper approximately 1" wide and 8" to 10" long.
B. Open the Door slightly, insert a strip of paper between the Gasket and Door Jamb

and close the Door.

C. Slowly pull the paper strip out. You should feel some resistance as you pull the strip

from between the Gasket and Door Jamb of a properly adjusted Door. Test the fit at
regular 2" to 3" intervals around the entire Door.

1. If you feel NO resistance at a particular spot the Door is too loose, you have
found a weak or damaged spot in the Door Gasket or the Door Jamb has been
bent in.

2. If you feel HEAVY resistance at a particular spot the Door is too tight or the
Door Jamb has been bent out.

XO–1M OWNER'S MANUAL SERVICE AND REPLACEMENT GUIDE

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
REPLACING OR REPAIRING 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.

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

#8 - DOOR GASKET

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.

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 ¼" 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.

IMPORTANT: DO NOT STRETCH OR PULL ON THE GASKET DURING
INSTALLATION. THIS WILL LATER CAUSE THE TRIMMED CORNERS TO

SEPARATE AND PULL APART!!!

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 is cut too short.

NU–VU® FOOD SERVICE SYSTEMS MENOMINEE, MICHIGAN 49858
[phone] SALES FAX [phone] • SERVICE FAX [phone] page 25

SERVICE AND REPLACEMENT GUIDE XO–1M OWNER'S MANUAL

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.

IMPORTANT: MAKE SURE THAT THE GASKET AND THE DOOR FRAME

ARE BOTH COMPLETELY DRY BEFORE APPLYING ANY SEALANT!!!

H. A quality sealant will be dry to the touch and tack-free in one to two hours after

application. Howver, 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.

CAUTION: SOME SEALANTS GIVE OFF ACIDIC FUMES AS THEY CURE.
THESE FUMES MAY CAUSE IRRITATION TO THE EYES AND NASAL
PASSAGES. USE CAUTION WHEN OPENING YOUR UNIT AFTER WAITING
FOR ANY FRESH SEALANT TO SET UP OR CURE!!!
