Installation
Use accessories on the inlet and exhaust lines whose materials and sealing proper-
ties are compatible with gases being used.
Provide in the pumping line, accessories to isolate the pump from the vacuum and ex-
haust line, to make the maintenance easier (inlet and exhaust isolation valves, purg-
es,H).
Remove the blanking plates blocking the inlet and exhaust ports.
Keep the blanking plates, screws and washers for reuse when transporting the pump.
Ensure that no screws, washers or other objects are dropped into the pump inlet.
Fit flexible flanged bellows in the pumping line to reduce the transmission of vibra-
tions.
The O-rings located under the blanking plates are not compatible with all the applica-
tions. The user and/or product OEM is responsible for installing an O-ring compatible
with the application.
Other types of connection accessories are available in the product catalogue. The inlet
and exhaust connections must not cause stress that could lead to leaks in the pumping
line.
5.5.1
Connection at pump inlet
To improve pumping speed, the pumping line must be as short as possible and its inter-
nal diameter must not be less than the pump inlet flange.
To control the isolation valve

5.5.2
Connection at pump exhaust
WARNING
Risk of crushing or cutting related to the rotating parts
Do not expose any part of the human body to the vacuum. The product is supplied with
the inlet and exhaust sealed.
Remove these blanking plates when you are ready to connect the product to your
vacuum system.
Do not operate the product unless the inlet and exhaust are connected to a vacuum
and exhaust pumping line.
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.
DANGER
Health risk in case of contact with toxic substances
Exhaust of corrosive, reactive, flammable, pyrophoric or oxidizing process gases may
result in severe injury or death.
Always connect the pump exhaust to an exhaust extraction system.
NOTICE
Limit of operation
Ensure that all components in the exhaust pipeline have maximum pressure rating
which is greater than the highest pressure that can be generated in your system.
