*Wire size and overcurrent protection must comply with the National Electric Code.

NOTES:

1.For altitudes above 2000 ft. reduce capacity 4% for each 1000 ft. above sea level.

2.Wire size based on copper conductors, 60°C, 3% voltage drop.

3.Continuous return air temperature must not be below 55°F.
