Installation; Connection Of Electrical Supply - Nu-Vu SUB-123 Owner's Manual

RECEIPT, INSTALLATION AND START-UP

INSTALLATION:

Record the Model Number and complete Serial Number of your unit in the spaces provided on page 47 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.
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" at the back and both sides of the unit. Mark the
locations of the electrical and optional water connections on the wall.
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
voltage and/or phase of your equipment.
IMPORTANT: DO NOT CONNECT THIS UNIT IF YOUR POWER SOURCE DOES NOT
MATCH THE REQUIREMENTS AS LISTED ON THE UNIT LABEL!
This equipment must be installed and connected in accordance with all applicable federal, state, province,
and/or local electrical codes having jurisdiction. 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 plug and
receptacle-type connection or direct wiring. Allow enough slack in the wiring to allow for equipment to be
moved during installation or any required maintenance and servicing.
WARNING: ALL POWER MUST BE TURNED OFF AT THE ELECTRICAL SUPPLY WHILE
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, phase and frequency requirements of the
unit and available power supply. The following instructions are for the most common 120/208 volt or
120/240 volt 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 (Line 1, Line 2, Line 3, and Neutral)
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.
IMPORTANT: IN A THREE PHASE SYSTEM ANY WILD LEG (MORE THAN 120 VOLTS
TO NEUTRAL) MUST ALWAYS BE CONNECTED TO L-2!
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.
