MERCHANDISER ELECTRICAL DATA
Refer to merchandiser serial plate for electrical
information.
FIELD WIRING
Field wiring must be sized for component
amperes stamped on the serial plate. Actual
ampere draw may be less than specified.
ALWAYS CHECK THE SERIAL PLATE FOR
COMPONENT AMPERES
ELECTRICAL CONNECTIONS
All wiring must be in compliance with NEC
and local codes. All electrical connections (for
remote models) are to be made in the electrical
Handy Box located behind the removable base
panel at the left end of the merchandiser when
facing the discharge honeycomb.
ELECTRICAL OUTLET
Before the merchandiser is connected to any
wall circuit, use a voltmeter to check that the
outlet is at 100% of the rated voltage. The wall
circuit must be dedicated for the merchandiser.
Failure to do so voids the warranty. Do not use
an extension cord. Never plug in more than one
merchandiser per electrical circuit.
• Always use a dedicated circuit with the
amperage stated on the unit.
• Plug into an outlet designed for the plug.
• Do not overload the circuit
• Do not use long or thin extension cords.
Never use adapters.
• If in doubt, call an electrician.

REFRIGERATION
(Self Contained Models)
Each self contained model is equipped with
its own condensing unit and control panel
located beneath the display area. The correct
type of refrigerant will be stamped on each
merchandiser's serial plate. The merchan-
diser refrigeration piping is leak tested. The
unit is charged with refrigerant, and shipped
from the factory with all service valves open.
Risk of Electric Shock. If cord or plug
becomes damaged, replace only with
a cord and plug of the same type.
Merchandiser must be grounded.
Do not remove the power supply cord ground.
