electrical shock may result unless power is turned off.
WIRING-MAIN POWER
Unit must be Installed In compliance with NEC and local
codes
Refer to electrical data on the unit data label and the
table on Page 8 of these installation Instructions, for field
wiring requirements The electrical data lists heater sizes,
fuse and wire sizes (60°C copper) for all models Also
shown are the number of field power circuits required for
the various models with heaters
NOTE
POWER SUPPLY SERVICE MUST BE WITHIN
ALLOW ABLE RANGE (+10%-5%) OF RATED
VOLTAGE STAMPED ON THE UNIT RATING
PLATE. TO OPERATE UNIT NOMINAL 208V/230V
AT 208V, CHANGETHE TRANSFORMER LINE TAP
FROM 240V TO 208V
Refer to the unit data label for wire sizing information and
maximum fuse or "HACR Type" circuit breaker size Each
unit Is marked with a "Minimum Circuit Ampacity" This
means that the field wring must be sized to carry that
amount of current On single phase models and
dependent on the installed KW of electric, it may be
possible to Use two (2) field power circuits in place of
one larger power supply circuit Use "Copper Conductors
Only" Refer to the National Electrical Code for complete
current carrying capacity data on the various insulation
grades of wiring materials
