Notes :
1. All 70 - 125 ton units are single point power.
2. 130 - 215 ton low voltage units and 240-400 ton units
require separate power connections for each circuit.
3. MOP - Maximum Overcurrent Protection - may be either
fused/HACR type breaker (UL/CSA) or with circuit breaker (CSA only).
MOP = 225 percent of the largest
compressor RLA plus 100 percent of the second compressor RLA, plus the sum of the
condenser fans FLA per NEC 440-22. (Use FLA per circuit, NOT FLA for entire unit)
4. MCA- Minimum Circuit Ampacity- 125 percent of largest
compressor RLA plus 100 percent of second compressor plus the sum of the condenser fans
FLA per NEC 440-33.
5. 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.
6. RLA - Rated Load Amps - rated in accordance with UL
Standard 465.
7. Local codes may take precedence.
8. Control kw includes operational controls only. Does not
include evaporator heat tape.
9. LRA - Locked Rotor Amps - based on full winding (x-line)
start units. LRA for Y-Delta starters is 1/3 of LRA of X-Line units.
10. VOLTAGE UTILIZATION RANGE:
| Rated Voltage |
Utilization Range |
| 200 |
180-220 |
| 230 |
208-254 |
| 460 |
414-506 |
| 575 |
516-633 |
11. 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.
12. Low ambient unit will have one additional fan on most
sizes. MCA will not change. See pages 53-55 for number of fans on
low ambient units.
