MERCHANDISER ELECTRICAL DATA
Merchandiser data sheets are shipped with this
manual. The data sheets provide case electrical
data, electrical schematics, parts lists and
performance data. Refer to the merchandiser
data sheets and case serial plate for electrical
information.
ELECTRICAL CONNECTIONS
All wiring must be in compliance with NEC
and local codes. All electrical connections are
to be made in the electrical raceway or Handy
Box.
FIELD WIRING
Field wiring must be sized for component
amperes stamped on the serial plate. Actual
ampere draw may be less than specified. Field
wiring from the refrigeration control panel to
the merchandisers is required for defrost termi-
nation thermostats and for optional refrigeration
thermostats. When multiple merchandisers are
on the same defrost circuit, the defrost termina-
tion
thermostats are wired in series.
ALWAYS
CHECK THE SERIAL PLATE FOR COMPONENT
AMPERES .
IDENTIFICATION OF WIRING
Leads for all electrical circuits are identified by
colored plastic bands. These bands correspond
to the color code sticker (shown below) located
inside the merchandiser’s raceway.
