The Cell Logic models are Type A2 and B2 Logics modified for use with a microscope
and/or the addition of a temperature-controlled work surface area. These units should
be treated the same as their corresponding Logic models with the following exceptions
noted:
1. Type A2 Cell Logics have a 9-inch sash opening. Refer to the following table for
inflow requirements:
Model 34309 34409 34509 34609
Cabinet Size (in feet) 3 4 5 6
Sash Opening (inches) 9 9 9 9
Starting Serial # 1 0705_ 0705_ 0705_ 0705_
Nominal Avg. Downflow (FPM) 55+/-5 55+/-5 55+/-5 55+/-5
Nominal Average Inflow (FPM) 105+/-5 105+/-5 105+/-5 105+/-5
Sash Open Area (Sq. Ft.) 2.28 3.03 3.78 4.53
Nominal Avg. Exhaust Vol. (CFM) 239 318 399 476
Avg. Exhaust Vol. Range (CFM) 228-251 303-333 378-416 453-498
2. The downflow velocity profile can be measured with a microscope in place,
simply omit those velocity points that are under or obstructed by the microscope
base.
3. On Cell Logic models equipped with the microscope sash, the secondary inflow
methodology is similar to that of the corresponding Logic model with the
following changes:
a. With the microscope disconnected from the sash seal, the holes in the
seal must be plugged.
b. The sash is lowered to the height specified for the corresponding Logic
model.
c. The probe height is the same as the corresponding Logic model.
d. When establishing the test point locations on the front grille, use the
same methodology as with the Logics, except the two center test points
are not used.
e. The correction factor for 5-foot Cell Logics with a microscope sash is 1.0.
