Note:
*For YC gas/electrics only.
**For TC and TE Cooling only and with electric Heat units only.
Notes:
1. Performance in table is with both motors operating.
2. High speed = both motors on high speed. Medium speed is one motor on high speed and one on low
speed. Low speed is both motors on low speed.
3. Power Exhaust option is not to be applied on systems that have more return air static pressure drop
than the maximum shown in the table for each motor speed tap.
