event that a customer desires to test 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 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.

CONSTRUCTION:

NU–VU® XO– series Ovens are constructed of stainless steel both inside and outside. All of
the exterior frame members and interior shells are welded to provide unparalleled durability,
rigidity, and log life construction. Components such as temperature controls, timers, switches,
motors, heating elements, and others are thoroughly tested before shipment. Ongoing research
and development projects are used to introduce the latest and most dependable parts.

SHIPMENT:

NU–VU® 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 NU–
VU® freight is paid by the buyer F.O.B. NU–VU®'s plant in Menominee, Michigan. Shipping
time may vary depending upon the original shipping point, time of year and shipper or shippers
used.

NU–VU® works closely with all of its customers in tracing shipments to speed delivery 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 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.

XO–1M 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, accidents or 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 packing
damage to the attention of the trucker.

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
[phone] immediately after filing a freight claim.

C. Uncrate the unit carefully and check the entire unit (top, sides, front and back) for any

visible or hidden damage.

D. Remove the unit from the shipping pallet and inspect the bottom (including the

Casters) 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 Oven Door. Make sure the Oven Door closes completely, and that the

Door Gasket seals firmly. If it does not close and seal properly please contact NU–
VU®'s Service Department for instructions and assistance in any required
adjustments.

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!!!
