d1g. Check booth pressure to see if it is at least -0.099 d1h. Repeat steps d1e through d1g until profile pressure is .5” to .7” and booth pressure is -0.099. If the AMU VFD must be set lower than 48hz, then there may be some other problem with the exhaust system. Check the exhaust duct, filters, fan serial plate, motor HP, belt tension, etc. to ensure all other external factors are accounted for. d1i. Ensure P42 is set lower than P1
