DEFROST SEQUENCES
Insight merchandisers require defrost cycles for
proper operation . Refer to the data sheets for
application data . The Time Clock initiates de-
frost . The evaporator fans continue to circulate
air across the evaporator coil, melting any frost
build-up .
If temperature termination is required, an
applicable defrost sensor must be installed on
the case .
MERCHANDISER ELECTRICAL DATA
Technical data sheets are also shipped with the
case . The data sheets provide merchandiser
electrical data, electrical schematics, parts lists
and performance data . Refer to the technical
data sheets and merchandiser 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 wireway 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 de-
frost termination thermostats and for optional
refrigeration thermostats . When multiple
merchandisers are on the same defrost circuit,
the defrost termination thermostats are wired
in series .
