2-4. How to tube
<Connecting to the Gas Detector Head>
To use the gas detector head GD-70D series and the pyrolyzer unit PLU-70 in combination, install tubes to
realize a flow in the following direction:
GAS IN -> PLU-70 -> Gas detector head GD-70D series -> GAS OUT
. Please use the dedicated U-tube supplied with the pyrolyzer to connect between the PLU-70 and the gas
detector head (between the PLU-70 OUT and the gas detector head IN).
CAUTION
•
Making incorrect tube connections may result in inaccurate gas detection. Double-check the tube
connections for errors.
No error message is displayed in particular even if the dedicated U-tube is connected incorrectly
(i.e., from the gas detector head to the PLU-70).
•
Use the dedicated U-tube supplied with the pyrolyzer unit to connect between the PLU-70 and
the gas detector head. Using other components invalidates the warranty of the performance.
CAUTION
•
Install tubes between the pyrolyzer unit and the gas detector head GD-70D series, putting the
pyrolyzer unit in front of the gas detector head.
•
Like the gas detector head, the pyrolyzer unit has a Rc1/4 thread inside of the sampling
inlet/outlet (GAS IN, GAS OUT), to which polypropylene unions are normally attached. Connect
the tubes basically in the same way as for the gas detector head. (See the operating manual for
the GD-70D series.)
