pressure rating of the bellows must be higher than the highest pressure generated
in the system. We recommend that you use the manufacturer's bellows.
▪
Install an inlet isolation valve in the pipeline between the vacuum system and the
pump. The inlet isolation valve isolates the vacuum system from the pump when
the system is set to off. This prevent the flow of the process gases and particles
back into the vacuum system.
▪
Make sure that the sealing surfaces are clean and are not scratched.
▪
We recommend that you use an exhaust extraction system appropriate for use
with all pumped process gases. Make sure that the exhaust extraction system is
not blocked or obstructed when the pump is in operation.
4.4 Leak test the system
CAUTION: SYSTEM LEAK TEST
Risk of injury or damage to equipment. Do the leak test of the system after
installation. Seal all the leaks found to prevent leakage of dangerous substances out
of the system and leakage of air into the system.
We will accept no liability or warranty claims for damages caused from flammable
mixtures because of air leaks.
1.
Do the leak test of the vacuum system after installation.
2.
Seal all the leaks found.
4.5 Electrical installation
WARNING: ELECTRICAL CONNECTION
Risk of electric shock. The electrical installation must be done by a qualified person.
Always make the electrical connections to the pump after the pump has been
installed on the vacuum system.
WARNING: INSTALLATION SAFETY
Risk of electric shock or damage to equipment. The pump must be electrically
installed in accordance with regional and local codes, and must obey the local and
national safety requirements.
WARNING: HAZARDOUS VOLTAGE
Risk of electric shock or damage to equipment. The logic interface is 30 V maximum
rated PELV and must only be connected to PELV interfaces. Failure to use an correctly
rated supply could result in electric shock.
The pump is a cord
‑
connected device rated at 8.5 A and must be installed in accordance
with local electrical regulations. The pump is to be supplied from a single phase 200 -
240 V branch circuit protected supply rated at 15 A maximum. Refer to
on page 35.
