INSTALLATION:
Record the Model Number and complete Serial Number of your unit in the spaces provided on page 21 of this
manual. You will need these numbers if you should ever need to contact our Service Department concerning
adjustments, replacement parts or other service needs. When calling for service or parts, try to be at the equipment
location so that we can better assist you with your service or parts needs.
Roll the unit into the exact position where it is to be operated. Make sure there will be enough clearance on each
side of the unit for proper cooling during operation, and for ease of access during maintenance or service.
NU-VU® recommends a minimum clearance of 4" (102mm) at the back and both sides of the unit. Do not install
this unit in a location where splashing or spaying of water onto exterior of unit is likely to occur.
Mark the locations of the electrical and water connections on the wall.
If required by code, standard or law; the appliance must be secured to the building structure when the appliance is
in service. The appliance is supplied with an eyebolt installed in the rear of the appliance for the purpose of
securing it to the building structure with a wire rope lanyard or welded steel chain.
Check the swing of both the Oven and Proofer Doors, making sure they have enough room to open completely
without hitting anything or obstructing the work area.
Move the unit out from its operating position and proceed with the service connections.
Connection of Electrical Supply - -
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 or phase
is not the same, please call NU-VU

service department at (800) 338-9886.
This equipment must be installed and connected in accordance with all applicable federal, state, province, and/or
local electrical codes having jurisdiction using properly rated all pole mains protection and all pole mains
disconnect. All electrical connections must be made with COPPER WIRE ONLY in the correct gauge for the
application. The unit may be connected either through a cord, plug and receptacle-type connection or direct wiring
using flexible conduit. Allow enough slack in the wiring to allow for equipment to be moved during installation or
any required maintenance and servicing.
The electrician should remove the Outside Top [71] to expose the power supply connections at the Power
Terminal Block [1] on top of the oven compartment. A wiring schematic is attached to the wiring near the power
terminal connections.
Proper electrical connections will vary depending on the voltage and phase requirements of the unit and available
power supply. The following instructions are for the most common configurations (refer to
Fig. #2 on page 5), and
may be modified to fit your installation.
A. The electrician must install a cable clamping device or cord restraint in the rear access hole. This cable
clamping device must be firmly attached to the unit, and appropriately sized for the power supply wire
or cord being used.
B. Take note of the labeling on the Oven terminal connections ( L ine 1 , L ine 2 and L ine 3 ) at the Power
Terminal Block [1].
C. Carefully identify the power source connections and attach them to the appropriate terminals. Make sure
all connections are clean and tight.
D. Be sure the unit is properly grounded BEFORE use by attaching a grounding wire to the Ground Lug [2]
next to the Power Terminal Block.
IMPORTANT: DO NOT CONNECT THIS UNIT IF YOUR POWER SOURCE DOES NOT
MATCH THE REQUIREMENTS AS LISTED ON THE UNIT LABEL!
WARNING: ALL POWER MUST BE TURNED OFF AT THE ELECTRICAL SUPPLY WHILE
THIS UNIT IS BEING CONNECTED!
IMPORTANT: IN A THREE PHASE SYSTEM ANY WILD LEG (MORE THAN 120 VOLTS TO
