FIOP — Factory-Installed Option

NOTES:

1.Heaters are rated at 240 v, and 480 v.

2.The factory assembled horizontal adapter substantially improves fan performance.

3.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 determine blower rpm, bhp, and watts.
