Table 12 — Accessory/FIOP Static Pressure (in. wg)

LEGEND

*Do not operate unit with electric heat at this cfm. Operation at this cfm

is below electric heat required minimum cfm.

†Do not operate unit at this cfm. Operation at this cfm is above unit

maximum cfm limit.

NOTES:

1. Heaters are rated at 208 v, 240 v and 480 v.
2. The factory assembled horizontal adapter substantially improves

fan performance. See Fig. 30.

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 Fan Performance table to determine
blower rpm, bhp, and watts.

Table 13 — Fan Rpm at Motor Pulley Settings* (Factory-Supplied Drives)

*Approximate fan rpm shown.

†Due to belt and pulley size, pulley cannot be set to this number of turns

open.

NOTE: To run units at speeds not listed, field-supplied drives are
required.

Table 14 — Indoor-Fan Motor Performance

LEGEND

*Extensive motor and electrical testing on these units ensures that the

full horsepower range of the motors can be utilized with confidence.
Using fan motors up to the horsepower ratings shown in this table will
not result in nuisance tripping or premature motor failure. Unit warranty
will not be affected.
