Bhp — Brake Horsepower
*Extensive motor and electrical testing on these units ensures that the
full horsepower and watts range of the motors can be utilized with con-
fidence. Using the fan motors up to the ratings shown in this table will
not result in nuisance tripping or premature motor failure. Unit warranty
will not be affected.
Table 9 — Accessory/FIOP EconoMi$er IV Static Pressure* (in. wg)
LEGEND *The static pressure must be added to external static pressure. The
sum and the evaporator entering-air cfm should be used in conjunction
with the Fan Performance tables to determine indoor blower rpm and
watts.

*Motor drive range: 680 to 1044 rpm. All other rpms require field-
supplied drive.
NOTES:
1. Boldface indicates field-supplied drive is required.
2. Maximum continuous bhp is 1.20.
3. See page 33 for general fan performance notes.
