Adjusting the optional inflow and downflow values
Note: This step is only available if the optional airflow sensor is installed.
1. Using the
▲
or
▼
buttons, increase or decrease the displayed inflow velocity
until it matches the observed value, then press “Mute/OK” to confirm the value.
The display will now change to downflow velocity calibration screen.
2. Using the
▲
or
▼
buttons, increase or decrease the displayed downflow velocity
until it matches the observed value, then press “Mute/OK” to confirm the value.
1. Once the downflow is confirmed, the unit will then automatically turn off and
then back on.
HEPA Filter Leak Test
All Logic models were tested to the HEPA Filter Leak Test as described in ANSI/NSF
Standard 49:2007.
Note: ensure all internal surfaces of the Logic have been appropriately
decontaminated before proceeding.
Figure 5-1
Note: For all Logic models, the aerosol
generator should be placed in the left
rear corner of the work area, pointing
toward the rear grille, as shown in
Figure 5-1.
If the Logic is contaminated
(An upstream concentration cannot be established)
If the Logic has been used with biohazardous, toxic chemicals, or radioisotopes, the DOP
access port cannot be used. The upstream concentration cannot be measured directly.
Testing at Labconco has shown the actual concentration varies from the calculated
value. Table 5-1 shows the actual vs. calculated concentrations for the A2 models.
