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. |
