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 TOASTMASTER®manufacturing facility.
If contacted, TOASTMASTER®will provide information on the nearest location and
availability. 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. If a customer wants
to try a specific product arrangements can be made to determine what conditions are
necessary for baking or cooking so 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.
CONSTRUCTION:
All Ovens of the XO series are constructed of stainless steel both inside and outside. All
of the exterior shell or frame members and the internal shells are welded to provide long
life construction, durability and rigidity. 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:
TOASTMASTER ® 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 TOASTMASTER®freight is paid by the buyer F.O.B. from the
TOASTMASTER®manufacturing plant in Menominee, Michigan. Shipping time may
vary depending upon the original shipping point, time of the year, and shipper or shippers
used.
TOASTMASTER®works closely with all of its customers in tracing shipments to speed
deliveries and minimize handling. TOASTMASTER®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.

TOASTMASTER®MODEL XO–1N:
The TOASTMASTER®XO–1N is electrically powered and operated, and generally does
not require a hood. However, the final decision as to hood requirements will always rest
with your local authorities.
The XO–1N can be used for the following bakery products:
•Breads · Pies · Pastries
•Rolls · Croissants · Cakes
Muffins · Pizza · Cookies
and many other miscellaneous products.
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 recipes, fan
speed, temperature, proofing conditions and environmental conditions.
All XO series Ovens are designed for the following:
•Automatic pan positioning · Easy cleaning
•Dependable components · Low maintenance
•Rapid, even baking · Simple operation
•Low energy consumption · Rapid servicing
Your TOASTMASTER®XO-1N Oven is equipped with a mechanical Temperature
Control and a 60-Minute Timer.

RECEIPT AND INSTALLATION
RECEIPT:
It is essential to inspect the unit immediately when it arrives. TOASTMASTER®has
placed instructions on the packaging to help avoid damage in transit. However, negligent
handling can 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
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
TOASTMASTER®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 TOASTMASTER®.
F. Check the Oven 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 the TOASTMASTER®Service Department for instructions and
assistance in any required adjustments.
INSTALLATION AND INITIAL START–UP:
A. 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.
B. Attach the included Appliance Legs to the bottom of the unit. Each Leg stud
screws into a threaded hole in each corner of the base.
C. Position the unit where it is to be operated and adjust the Appliance Legs so the
unit stands level and solid. TOASTMASTER®recommends a minimum 1” spacing
all around the sides and back of the unit when installed.
D. Carefully set all Controls and Switches to the OFF position.
E. Connect your unit with the attached 120 volt/20 amp Power Cord to a 120 volt/20
amp receptacle (NEMA 5–20R or the equivalent). Allow enough slack in the
Power Cord to allow for equipment to be moved about during installation and any
future servicing.
F. Open the Oven Door. The Blower Wheel should slow to a complete stop.
IMPORTANT NOTICE: ALLOW THE BLOWER WHEEL TO COME TO A
COMPLETE STOP BEFORE REVERSING THE OVEN MOTOR. FAILURE
TO DO SO MAY RESULT IN DAMAGE TO THE MOTOR OR SWITCH!

G. Set the Temperature Control to 300 . The Temperature Control Indicator Light
will illuminate and the Oven will begin to heat up.
H. Set the Timer to 5 minutes and allow it to count down to 0. The Buzzer should
sound at the end of the timed cycle. If the Buzzer and/or Timer does not work
please refer to the TROUBLE–SHOOTING GUIDE.
I. Remove the Rear Access Panel to expose the Power Cord connections. Use a
multi-meter to measure the amperage on the power supply lines. Compare these
readings to the label on the side of your unit. If the readings and label differ by
any great amount turn the unit OFF and call the TOASTMASTER®Service
Department immediately at [phone]. Carefully replace the Rear Access
Panel if the amp readings and label coincide.
J. Place an accurate and reliable oven thermometer in the center of the Oven and
allow the Oven to heat to 300 . Compare the thermometer reading and the
Temperature Control setting when the Temperature Control Indicator Light goes
out. If they differ by less than 10 the Oven is ready for use. If there is a difference
of 10 or more you may wish to adjust the Temperature Control calibration. Please
call the TOASTMASTER®Service Department at [phone] before
attempting to recalibrate the Temperature Control!!!

OPERATING INSTRUCTIONS
The quality of the product you take from your TOASTMASTER®XO–1N Oven depends
on several factors:
•Initial product quality
•Proper storage and handling
•Proper preparation and proofing
•Correct baking time
•Correct baking temperature
Non-yeast products are part of many baking programs. Some of these products are in frozen
form when received, such as cookies and puff pastry. Baking times and final appearance are
affected by the condition of the product when placed in the Oven. For instance, formed
cookies placed on pans and baked without thawing tend to spread less and bake smaller but
thicker than the same cookies allowed to thaw before baking.
When using yeast products it is important that they be properly prepared. Your equipment
cannot correct improper procedures and poor dough product. The manual or instruction
book you receive from your frozen dough supplier should give general instructions for
baking times and temperatures. Or, the following chart may be used as a general 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
It will be necessary for your to do some testing to determine your final conditions since your
recipes may vary and your desired product appearance is one of choice.

Your XO–1N is equipped with a Micro Switch. This Switch is mounted in the front face
and is designed to reduce heat loss by stopping the rotation of the Blower Wheel whenever
the Door is opened.
Follow these general instructions for proper baking results:
1. Determine the product to be baked.
2. Check the recommended temperature for the items to be baked and set your
Temperature Control accordingly.
3. Load your Oven carefully. Push the pans all the way to the rear of the Oven. Keep
the Oven Door CLOSED unless loading or unloading to maintain oven
temperature and minimize energy usage.
4. Set the Timer for the estimated baking time less one to two minutes. This will
assure an indication from the Buzzer prior to the actual end of the baking time and
help prevent over-baking.
5. 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.
6. You may bake several different items at the same time, but each individual pan
should have the same type of product on it and be panned in the same manner.
7. 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 (see the DAILY DRY–OUT PROCEDURE in the MAINTENANCE
AND CLEANING GUIDE).
CAUTION: STAND AWAY FROM THE FRONT OF THE OVEN WHEN
OPENING THE OVEN DOOR AFTER A BAKING CYCLE TO AVOID
EXPOSURE TO ESCAPING HEAT AND STEAM!!!
IMPORTANT: THE OVEN MOTOR MUST ALWAYS BE RUNNING
WHENEVER THE OVEN TEMPERATURE CONTROL IS ON EXCEPT
WHEN THE OVEN DOOR IS OPEN TO LOAD OR UNLOAD YOUR
PRODUCT!!!

MAINTENANCE AND CLEANING GUIDE
MAINTENANCE:
TOASTMASTER® 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 TOASTMASTER® 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 water, both inside and outside of the Oven.
B. Set the Temperature Control and Power Switch to OFF.
C. Leave the Oven Door open as far as possible. The residual baking heat will dry out
any moisture that may be trapped in the insulation or other components of the
Oven.
D. Close the Oven Door most of the way, but leave it slightly open 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 SERVICE LIFE OF YOUR TOASTMASTER®EQUIPMENT!!!

CLEANING:
Your XO–1N 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:
A. The stainless steel exterior may be cleaned with any good stainless steel cleaner or
polish, or with hot soapy water followed by a clear rinse if it is very soiled.
B. The Door can be removed for ease of cleaning by opening the Door slightly and
using a ½” wrench or socket, remove the top hinge bolt and tilt Door until it is
clear of the top hinge and then lifting the Door straight up. Do not loose the bronze
bushings from the top or bottom hinges, the door will not operate properly without
them. All glass should be cleaned with a glass-cleaning formula. Baked-on or
excessive soiling can be removed with soap and hot water followed by a thorough
rinse with fresh clean water. Severe deposits may be loosened and removed by
soaking in a stronger soap and water solution.
C. The Oven interior should be cleaned on a regular basis with mild soap and hot
water followed by a thorough rinse with clean fresh water. Wipe all items dry to
prevent water spotting.
* * * CAUTION * * *
TOASTMASTER®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), the silicon rubber Door Gaskets, or
any of the sealing compound in the Oven seams and joints. These compounds may cause
discoloration and degradation of these parts resulting in permanent damage. DO NOT use
bleach or bleach compounds on anychromed parts; bleach may damage chrome plating.
NOTE:
TOASTMASTER® 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 TOASTMASTER®(Part #51–
0002) or through your local Rochester/Midland distributor or representative.
* * * NOTICE * * *
NATIONAL SANITATION FOUNDATION GUIDELINES REQUIRE THAT ALL
INTERIOR PARTS BE REMOVABLE WITHOUT THE USE OF TOOLS. THIS
EQUIPMENT HAS BEEN FACTORY ASSEMBLED TO SAFELY
ACCOMMODATE ROUGH HANDLING THROUGH SHIPMENT AND ORIGINAL
INSTALLATION. AFTER ANY MAINTENANCE, CLEANING OR REQUIRED
SERVICE WORK THE INTERIOR SHEET–METAL PARTS SHOULD BE RE–
ASSEMBLED AND FASTENED HAND–TIGHT ONLY, BUT STILL REMAIN
