4 Installation
Skilled personnel
The vacuum connection may only be established by persons who have
suitable technical training and the necessary experience or who have
been instructed by the end-user of the product.
DANGER
Caution: overpressure in the vacuum system >1 bar
Injury caused by released parts and harm caused by escaping process
gases can result if clamps are opened while the vacuum system is
pressurized.
Do not open any clamps while the vacuum system is pressurized. Use
the type clamps which are suited to overpressure.
Caution
Caution: dirt sensitive area
Touching the product or parts thereof with one's bare hands increases
the desorption rate.
Always wear clean, lint-free gloves and use clean tools when working
in this area.
Caution
Caution: vacuum component
Dirt and damages impair the function of the vacuum component.
When handling vacuum components, take appropriate measures to
ensure cleanliness and prevent damages.
Keep the protective lids.

Skilled personnel
The compressed air connection may only be established by persons
who have suitable technical training and the necessary experience or
who have been instructed by the end-user of the product.
Caution
Specifications for the compressed air:
•=free of particles >5 µm
•=3 ... 7 bar overpressure
•=dry, free of oil or containing oil (Keep using the same quality).
If using compressed air which contains oil, dispose of it in accordance
with the relevant regulations.
Caution
Specifications for the plastic tube:
•=bursting pressure ≥10 bar overpressure (1 MPa)
•=material: PA soft or PU.
Caution
To ensure leak tightness of the instant push-in fitting
•=cut the plastic tube square
•=make sure the outside of the plastic tube is not damaged.

Caution: plastic thread
The plastic thread is damaged by tilting or overturning the instant
push-in fitting.
•=use the enclosed instant push-in fitting (with extra-long thread)
only.
•=screw in the instant push-in fitting without tilting it and without
exceeding the tightening torque of 0.5 Nm.
The compressed air control system has to be provided by the end-user.
For connection of a ø6 mm plastic tube, exchange the instant push-in fitting.
