Fan Performance Using Accessory Power Exhaust

(551A155,180)

	NOTE: The CRRFCURB013A00 horizontal supply/return adapter accessory
NOTE: The CRRFCURB013A00 high static regain adapter accessory may be	improves 551A155,180 fan performance by increasing external static pressure
	by amount shown above. To convert from in. wg to Pa use the following formula:
used to provide horizontal supply/return.
	in. wg x 249.1 = Pa
