BUCK BioAire
™
Model B520 Operation
The
BioAire™
Model B520 Pump provides a
selectable, continuous, constant sample flowrate and
is very simple to operate. No tools are requried. Its
quiet operation allows unobtrusive sampling in IAQ,
medical, clean room, public and residential building
applications.
The front key pad is organized into three functional
key groups:
Power
(ON-OFF),
Timing
(1, 2, 5, 10
minute samples), and
Calibration
(Cal mode,
Increase flow, Decrease flow). Positive tactile
feedback is provided by the keys. The
BioAire
™
Model
B520 Pump internal NiCad batteries provide a full five
hours continuous run time at 15 LPM. The standard
charger provides a battery recharge in 12-16 hours
and allows the unit to operate on AC power; the
optional FastOne
™
Charger provides a battery
recharge in one hour.
End of sample notice is provided by the lit LED
“Complete” and three short beeps.
BioAire™
Model B520 Sampling Steps
Before sampling, ensure the battery is fully charged
and that the “Low Battery” LED is not on. For greatest
accuracy, the
BioAire
™
Model B520 Pump should be
calibrated once a day.
1. Place pump in desired location.
2. Immediately before sampling, lift up the label from
the inlet and outlet of the cassette and attach
them to the cassette sides.
3. Push the cassette (outlet side down) firmly down
into the sample fitting on top of the BioAire
™
Model B520 Pump until it fits snugly.
4. Push the “ON” button to power up the BioAire
™
Model B520 Pump and either: (a) continue to hold
the “ON” button for four seconds to put pump in
“Continuous” mode, or (b) push one of the
programmed time keys (1, 2, 5, or 10 minutes) for
an automatic timed sample.
5. At the end of programmed sample period, pump
will automatically shut off and “Complete” LED will
be lit; under “Continuous” mode, push and hold
“OFF” button for 2 seconds to shut off pump.
6.
Pull cassette up off pump with a twisting motion
and replace inlet and outlet stickers.
7. Package the cassette(s) and send to appropriate
laboratory for analysis.

Calibration of the
BioAire™
Model
B520 Pump is fast and easy. The supplied calibration rotameter
assembly fits securely on top of the bioaerosol cassette with no
leakage, so all your sample airflow goes through the bioaerosol
cassette. Flow calibration with an actual cassette in-line en-
sures an accurate and repeatable calibration, without substitute
restrictors, bubble tubes, or other fittings.
BioAire™
Model B520 Calibration
For greatest accuracy, the
BioAire
™
Model B520 Pump should
be calibrated once per day. Calibration is performed with an
actual bioaerosol cassette in-line, not a substitute flow restrictor
as in other designs. The
BioAire
™
Model B520 Pump is a
constant flow device specially designed to accommodate the
natural backpressure inherent in 37mm bioaerosol cassettes. It is
for use only with such bioaerosol sampling cassettes.
1. Connect the flowmeter to the inlet of the calibration fitting.
2. Remove labels or caps from biaerosol cassette (retain for
later use), push calibration fitting down onto the top of the
cassette and firmly push both pieces into the sample fitting
on top of
BioAire
™
Model B520 .
3. Push “ON”, then “CAL” to put pump into calibratiion mode;
pump will operate at last calibrated flowrate. Adjust flowrate
using the
▲
and
▼
keys to set center of rotameter ball to the
desired flow rate mark on rotameter. Fine adjustments are
possible. Allow pump to stabilize.
4. When flowrate is achieved, push “CAL” to accept setting,
then turn pump off.
