5.8 Connecting the part/installation to be tested
● The inlet pressure must be no higher than atmospheric pressure. Pressure that is too
high can damage the product.
● The detector's performance depends on the type of accessories used and on the qual-
ity of the mechanical connections.
● When assembling the vacuum circuit, use accessories to shut off the product and
make maintenance easier (inlet shut off valves, purge systems, etc.).
● The maximum permitted weight at the detector's inlet must be no more than 15 kg and
the maximum torque must be 10 N·m.
● Comply with these recommendations (see 5.1) to optimise measurement.
Remove the blanked-off flange that covers the detector's inlet and save it for reuse
during storage or transport.
Connect the part or the equipment using the connection accessories available in the
product catalogue.
Test that the entire line is completely sealed when the detector is attached to the
pumping circuit, to ensure that the connections are correct (pump, pipe, valves, etc.).
5.9 Connecting the exhaust
Dry Model The detector's exhaust is equipped with an external filter.
Make sure that it is never obstructed: clean it regularly.
Wet Model
The detector's primary pump is equipped with an internal oil mist eliminator.
The operator can connect an external eliminator instead of this internal eliminator.
Install a pipe connection designed for this purpose, available as an accessory (see chap-
ter Replacement of the internal oil mist eliminator with an external oil mist elimina-
tor in the Maintenance Instructions).
NOTICE
Limit of operation
Make sure that the parts or chambers connected to the inlet of our products withstand
a negative pressure of 1 · 10
3
hPa in relation to atmospheric pressure.
NOTICE
Limit of operation
Make sure the exhaust pressure does not exceed 200 hPa (relative). Pressure that
is too high can damage the product.
NOTICE
Wet Model - Pumping at high pressure
Connect the exhaust to an exhaust duct. 1/8 Gas connection.
