NOTES:
1. Heaters are rated at 208/240 v and 480 v.
2. The factory assembled horizontal adapter substantially improves fan
performance. See Fig. 23.
3. The static pressure must be added to external static pressure. The
sum and the indoor-air section entering-air cfm should then be used
in conjunction with the Tables 5 and 6 to determine blower rpm, bhp,
and watts.

*Extensive motor and electrical testing on these units ensures that the
full horsepower range of the motors can be utilized with confidence.
Using your fan motors up to the horsepower ratings shown in this table
will not result in nuisance tripping or premature motor failure. Unit war-
ranty will not be affected.
