Type B2 Footnotes - Labconco Logic+ A2 Technical Manual

Type B2 Footnotes

Type and Model Identification

The primary serial tag is on the lower right edge of the front dress panel.
 The secondary serial tag is on the front of the electronics module on the cabinet's top right side.

The first two digits of the serial number are the year of production; the next two are the month. The next 5
digits are the sequence of production, and the letter following the serial number is the revision level of the
cabinet.

See Section 3:Catalog Number Configurator to discern Type, Model, and Sash Height from Catalog Number
found on the serial tag.
Downflow Test Specifications

All models are classified as uniform downflow.

All tests performed as described in the current NSF/ANSI Standard 49.

UV Lamp, IV bar and all other accessories must be removed before measuring downflow.
Inflow Test Specifications

All tests performed as described in the current NSF/ANSI Standard 49.
Secondary Inflow Test Specifications

Must use Labconco holder P/N 3836405 to perform this test properly.
1. Use the appropriate template included in Certifier Kit# 3858400.
2. Measured from bottom edge of the probe holder to center of the thermal anemometer element.

Locate the single row of holes at the front of the grille. Mark the 6
test points every 9 holes until the number of test points marked equals the width of the cabinet in feet (i.e. 4-
foot cabinet, mark the first 4 points). Repeat for the opposite side.
HEPA Filter Leak Test Specifications
3. Based on mineral oil.
4. The actual aerosol concentration is what was observed during testing.

Aerosol generator should be placed in the left rear corner of the work area, pointing at the rear grille.

For uncontaminated units, the upstream concentration for the Supply HEPA only can be sampled from the
tube located under the work surface.
Supply and Exhaust HEPA Filter Specifications
5. Without gasket
Motor / Blower Specifications

Each motor must be programmed by Labconco for the appropriate width cabinet. The PWM setting will
fluctuate depending on local temperature and pressure.
LED Lamp Specifications
7. THIS PRODUCT USES DIRECT DRIVE T8 LED LAMPS INSTEAD OF FLUORESCENT LAMPS. THERE
IS NO BALLAST; LINE VOLTAGE IS SUPPLIED TO THE LAMP SOCKETS. DO NOT INSTALL
FLUORESCENT LAMPS! FOR REPLACEMENT LED LAMPS, CONTACT LABCONCO PRODUCT
SERVICE DEPARTMENT.
Remote Exhaust System Data
8. DIM = Direct Inflow Meter
9. Total Exhaust Volume required from remote (building) exhaust system.
10. Measured as per ASHRAE methodology for measuring air volume in round ducts. These values are
approximations, as the calculated traverse volume value may vary depending on sampling location, exhaust
system, and methodology.
11. Measured at the exhaust transition sampling point, relative to atmosphere.
UV lamp Specifications

For all models, the UV lamp model is G30T8. Labconco p/n is 1271300.

For all 115/230 VAC models, the ballast assembly is Labconco p/n 3829901.
