1. Fan performance is based on wet coils, economizer, roof curb,
13.44
cabinet losses, and clean 2-in. filters.

2. Conversion — Bhp to watts:
16.68
—
Watts =
—
Motor efficiency

3. Variable Air Volume units will operate down to 70 cfm/ton. Per-
—
formance at 70 cfm/ton is limited to unloaded operation and may
—
be additionally limited by edb (entering dry bulb) and ewb (enter-
—
ing wet bulb) conditions.
