Installation — Electrical
Installer-Supplied Components
All wiring must comply with local codes and the National Electrical Code. The
installing (or electrical) contractor must provide and install the system inter-
connecting wiring, as well as the power supply wiring. It must be properly
sized and equipped with the appropriate fused-disconnect switches. The type
and installation location(s) of the fused-disconnects must comply with all
applicable codes.
The installer must provide the following components if not ordered with the
unit:
• Power supply wiring (in conduit) for all field-wired connections.
• All control (interconnecting) wiring (in conduit) for field supplied devices.
• Fused-disconnect switches.
Remote Evaporator Only:
• Control wiring between the outdoor unit and the evaporator terminal box.

(1) MOP - Maximum Overcurrent Protection - may be either type breaker (UL/CSA) or with circuit breakers (CSA only). MOP = 225 percent of the largest
compressor RLA plus 100 percent of the second compressor plus the sum of the condenser fans FLAs per NEC 440-22.
(2) MCA - Minimum Circuit Ampacity - 125 percent of largest compressor RLA plus 100 percent of second compressor plus the sum of the condenser
fans FLAs per NEC 440-33.
(3) RECOMMENDED TIME DELAY OR DUAL ELEMENT (RDE) FUSE SIZE: 150 percent of the largest compressor RLA plus 100 percent of the
second compressor RLA and the sum the condenser fan FLAs.
(4) RLA -Rated Load Amps -rated in accordance with UL Standard 465.
(5) Local codes may take precedence.
(6) Control kw includes operational controls only. Does not include heat tapes.
(7) LRA - Locked Rotor Amps -based on full winding start units.
(8) VOLTAGE UTILIZATION RANGE:
Rated Voltage Utilization Range
200/60 180-220
230/60 208-254
460/60 414-506
575/60 516-633
400/50 340-460
(9) 60 HZ UNITS - A 115/60/1, 15 amp. customer provided power connection is required to power the evaporator heat tape 420 watts
(10) 50 HZ UNITS - A separate 220/50/1 15 amp. customer provided power connection is needed to power evaporator heat tape 420 watts @ 220 volts.
