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 “ OK/Mute ” 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 “ OK/Mute ” to confirm the value.
3. Once the downflow is confirmed, the unit will then automatically turn off and
then back on.
Type A HEPA Filter Leak Test
Information
All Logic+ models were tested to the HEPA Filter Leak Test as described in ANSI/NSF
Standard 49:2012.
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 Type A
models.
