Notes:
1. As standard, all 70-215 ton units require a single point power connection.
2. Max Fuse or HACR type breaker = 225 percent of the largest compressor RLA plus 100 percent of the second compressor RLA, plus the sum of the condenser fan
FLA per NEC 440-22. Use FLA per circuit, NOT FLA for the entire unit).
3. MCA - Minimum Circuit Ampacity - 125 percent of largest compressor RLA plus 100 percent of the second compressor RLA plus the sum of the condenser fans
FLAs per NEC 440-33.
4. 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 of the condenser fan FLAs.
5. RLA - Rated Load Amps - rated in accordance with UL Standard 1995.
6. Local codes may take precedence.
7. Control kW includes operational controls only. Does not include evaporator heat tape.
8. LRA - Locked Rotor Amps - based on full winding (x-line) start units. LRA for wye-delta starters is 1/3 of LRA of x-line units.
9. VOLTAGE UTILIZATION RANGE:
Rated Voltage Utilization Range
200 180-220
230 208-254
380 342-418
460 414-506
575 516-633
10. A 115/60/1, 15 amp customer provided power connection is required to operate the unit controls. A
separate 115/60/1, 15 amp customer provided power connection is also needed to power the evaporator
heat tape (420 watts @ 120 volts). If the optional control power transformer is used, the customer needs
only to provide a power connection for the evaporator heat tape.
11. If factory circuit breakers are supplied with the chiller, then these values represent Maximum Overcurrent
Protection (MOP).
