Cautions
• Pump only clean, dry air.
• Protect pump from dirt and moisture.
• Pump is not intended for use outdoors.
• Protect surrounding items from pump exhaust air.
• Use only a three-wire grounded cable.
• Pump produces a high-pitched whine when operated.
• Do not pump fl ammable or explosive gases.
• Do not operate pump in hazardous locations; not UL Listed for intrinsic safety
Operation
The Vac-U-Go Sampler can be operated in two diff erent modes: non-compensating
and BioSampler. Vac-U-Go is non-compensating, therefore, it is not suitable for
compliance sampling in non-sonic mode. For indoor air studies, compliance, or other
applications that require a quiet, compensating vacuum pump, use the QuickTake 30
or QuickTake 15 Sample Pump.
Non-compensating Mode
1. Use
fl exible tubing to connect the outlet of a
representative sample medium to the pump
inlet.
2. Connect a rotameter or calibrator to the
sample medium inlet.
3. Using the provided power cable, plug the
pump into a wall outlet and press the pump
power switch to the “on” position.
4. Use the valve adjust to set the desired fl ow
rate (see rotameter/calibrator operating instructions).
5. Remove rotameter or calibrator and replace representative sample medium with a
new unexposed medium.
6. Sample for the desired sampling period.
7. Turn
off pump and unplug from wall outlet.
8. Package sample appropriately for shipment to a laboratory.
BioSampler Mode
1. Prepare BioSampler (see BioSampler
Operating Instructions). Use fl exible
tubing to connect the BioSampler
outlet to the pump inlet.
2. Using the provided power cable,
plug the pump into a wall outlet
and press the pump power switch
to the “on” position.
3. Use the valve adjust to open the
valve fully. The pressure gauge
should indicate > 15 inches Hg vacuum.
Note: The BioSampler features built-in critical orifi ces. No other orifi ce is needed to achieve
sonic fl ow.
