FlOP -- Factory-Installed Option 3.
*There are no electric heaters available for 017 676-v units.
NOTES:
1. Heaters are rated at 240 v, 480 v, and 676 v.
2. The factory assembled horizontal adapter substantially
improves fan performance.
The static pressure must be added to external static pressure.
The sum and the evaporator entering-air cfm should then be
used in conjunction with the Fan Performance table to deter-
mine blower rpm, bhp, and watts.
