0.1 Mechanical Hazards
1
In order to avoid the destruction of systems and injury to operating
personnel we urgently recommend to observe the information and
installation information provided in these Operating Instructions.
2
Avoid exposing any part of the human body to the vacuum.
3
Do not operate the pump with an opened intake port. There exists the
risk of suffering injury.
4
The pump is intended for generating a vacuum only. If an
overpres-
sure
can occur in the pump and the system then they must be pro-
tected against such an overpressure by an overpressure safety valve,
for example.
5
The maximum permissible discharge pressure for the LEYVAC is
1.3 bar abs.
We recommend to operate the pump with a silencer or a connected
discharge line. The pressure in the discharge line must not exceed
atmospheric pressure by 300 mbar max.
Make sure that the gas flow at the discharge is not blocked or restrict-
ed in any way, even when the pumped out gases need to be collected
or contained.
No shutoff devices are required in the discharge line for pump opera-
tion. If shutoff devices are installed, open them before starting the
pump.
In the case of processes involving much condensate, we recommend
the installation of a condensate separator in the discharge line.
6
Protect the purge gas supply so that in the event of a malfunction or
power interruption no overpressure can occur within the pump system.
7
We recommend to design the discharge line in consideration of a pos-
sible overpressure of 5 bar. In the event of a malfunction, such a pres-
sure can occur briefly.
8
For
transporting
the pump use only suitable transport means.
When selecting the lifting and transport means take note of the total
weight before transporting the pump.
Only the qualified personnel are allowed to unload and lift the pump.
When elevating the pump, no personnel should be under the object.
As standard the pump has been equipped with a single crane eye.
When transporting the pump with a forklift or similar, ensure that the
pump has been secured on the forks or on a suitable pallet.
Alternatively use two nylon slings as hoisting devices.
Be careful not to overturn the pump when pushing or pulling the pump
sideways.
