P is the fluid pressure in ft of head.
NOTES:
1.
This accessory glycol coil is intended for use with a MINIMUM of 25% glycol solution. It
IS NOT intended for use solely with water due to freeze-up conditions and the resulting
water damage to the conditioned space.

FAN PERFORMANCE — 551A155,180 UNITS
LEGEND
*Standard low-medium static drive range is 834 to 1064 rpm (for 208/230 and 460-v units).
Alternate high-static drive range is 1161 to 1426 (for 208/230 and 460-v units). Other rpms
require a field-supplied drive.
NOTES:
1.
Maximum continuous bhp for the standard motor is 3.13 (for 208/230 and 460-v units).
The maximum continuous watts is 2700 (for 208/230 and 460-v units). Do not adjust
motor rpm such that motor maximum bhp and/or watts is exceeded at the maximum
operating cfm.
2.
See page 162 for general fan performance notes.
