42BHC,BVC WATER PRESSURE DROP (ft. wg) FOR CV FACTOR AND WATER FLOW RATE (GPM)
NOTE: Table interpolation is permissible, and extrapolation is not rec-
ommended.
SOUND POWER DATA
DISCHARGE SOUND RATINGS — A-WEIGHTED SOUND POWER LEVEL RATINGS* (dB)
*These noise ratings are calculated values, not actual test values, and
apply only to the discharge of the unit, not the radiated sound levels.
Sound power is in decibels re 10e-12 w.
