MERCHANDISER ELECTRICAL DATA
Merchandiser data sheets for specific models are
shipped with this manual. The data sheets provide
merchandiser electrical data, standard electrical
schematics, parts lists and performance data.
Refer to the merchandiser data sheets and case
serial plate for electrical information. Refer to
the separate wiring diagrams shipped with the
case for specific information about the case and
any optional wiring kits that may have been
applied.
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 termination thermostats and for
optional refrigeration thermostats. When multiple
merchandisers are on the same defrost circuit, the
defrost termination thermostats are wired in series.
ALWAYS CHECK THE SERIAL PLATE FOR
COMPONENT AMPERES.
Electric Defrost is standard for low temperature
merchandisers and requires temperature termina-
tion. Gas defrost is optional
Off Time Defrost is standard for medium temper-
ature merchandisers and is time terminated.
When two or more merchandisers with full length
raceways are installed in line, remove the splash-
guards, end caps and raceway covers, and install
the nipple and nuts (supplied) providing electrical
passage from one merchandiser to the next.
Following NEC and local codes is the
responsibility of the electrical contractor.
ELECTRICAL CONNECTIONS
All wiring must be in compliance with NEC and
local codes. All electrical connections are to be
made to the terminal blocks in the electrical race-
way behind the lower front panel at the right-
hand end of the merchandiser (facing front).
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 raceway.

WIRING COLOR CODE
Leads for all electrical circuits are identified by a colored plastic band: neutral wire for each
circuit has either White insulation or a White plastic sleeve in addition to the color band.
