Calculation:
• Inflow Velocity (V1) = Inflow Air Volume (V2)/Actual Inflow Area (A2)
Acceptance:
• 100 – 110 FPM
Correction measures:
• Enter the service level and activate S2, change S2 until the desired
velocity is reached and save the new value.
• If the velocity can't be adjusted due to clogging of the filters, change the
exhaust filter.
• If the filter is in order, change the exhaust blower.
Note Check of alarm limits: If S1 or S2 are changed, the alarm limits S3
and S4 must be checked and saved again.
