1. Same conditions used for Voltage Tolerance Tests.
2. The wet bulb temperature condition is not required when testing air-cooled condensers which do not evaporate condensate.
3. Same conditions used for Voltage Tolerance Tests (Heating-only units).
4. For two speed, two compressor or units with compressor unloading capability.
5. Wet bulb sufficiently low that no condensate forms on evaporator.

All tests are performed at condenser speed and indoor blower speed intended for normal operation.
NOTES:
1. Not Maintained if no condensate rejected to outdoor coil.
2. Optional test used to determine the Designed Heating Requirement (DHR). The nominal speed is the lesser of the cooling and heating maximum speeds.
3. Optional equations may be used in lieu of the maximum speed test. The intermediate speed is the same as the cooling intermediate speed.
4. Wet bulb sufficiently low that no condensate forms on evaporator.
