Connecting the Water Exhaust Tube
The waste water should pass into a suitable drain such as a floor
drain or a vented container. To connect the drain tube:
1. Push the connector on the supplied length of drain tubing into
the WATER EXHAUST fitting on the back panel.
2. Place the other end of the drain tube in a vented container or
over a floor drain.
Connecting the Aerosol Supply
The Model 651 allows you to conduct aerosol sampling from either
the front or the back of the instrument. To run the instrument
effectively, you need an external vacuum capable of drawing
6 SLPM at 400 mbar absolute pressure.
Sampling options include the following:
Ambient sampling using the inlet screen assembly (provided
with the monitor) connected to the Model 651 inlet. The inlet
screen assembly prevents large matter (such as insects and dirt)
from entering the instrument.
Note: If you are sampling from the back of the instrument, you
must use the inlet screen assembly and the flow rate must
be 3 L/min when using the inlet screen.
