6 OM-SN-E
1. Electrical Supply Connection
Current and power demands for each unit are as shown above.
A. Panel Removal
Open the wiring and control panel by removing screws from the right side
panel. Slide the panel forward, and set it aside.
B. Supply Voltage
The unit must be operated at the rated nameplate voltage.
C. Phase Selection
Refer to steamer schematics (Pages 17-18) for wiring information.
D. Terminal Block
The terminal block for incoming power is located at the back of the control
compartment. The ground terminal is located in the wiring compartment
near the terminal block.
E. Supply Wire
To determine the type of wire you need for the power supply, find the
operating voltage and number of phases on the unit data plate. Refer to
the table below or to the label on the units back for correct wire size and
temperature rating. The equipment grounding wire must comply with the
National Electrical Code (NEC) requirements. The schematic on the inside
of the units right side cover gives directions for proper connection of the
terminal block jumpers. The specified wire must be used, or the unit will
not meet Underwriters Laboratories and NEC requirements. The knockout
hole is sized for a ¾ inch conduit fitting on the 3-pan and for a one inch
conduit fitting on the 5-pan.
F. Branch Circuit Protection
Each Steamer, including individual units of stacked models, should have
its own branch circuit protection and ground wire. Current and power
demands for each unit are as shown above.
CAUTION
DO NOT INSTALL THE UNIT WITH THE
RIGHT OR LEFT SIDE VENTS BLOCKED OR
WITHIN 12 INCHES OF A HEAT SOURCE
(SUCH AS A BRAISING PAN, DEEP FAT
FRYER, CHARBROILER OR KETTLE).
TO AVOID DRAINAGE PROBLEMS, LEVEL
THE UNIT FRONT TO BACK.
