NOTE: For high altitude conversion, an orifice change may also be required. See Form 035-14460-001 for application information.
* 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.
* ESP (External Static Pressure) .5" WG is at furnace outlet ahead of cooling coil.
NOTES:
1. All filters must be high velocity cleanable type.
