Take appropriate precautions to ensure that the pump cannot start.
If the pump has pumped hazardous gases it will be necessary to determine
the nature of the hazard involved and take the appropriate safety precautions.
Observe all safety regulations!
Take adequate safety precautions prior to opening the intake or exhaust port.
Failure to observe the following precautions could result in damage to
the equipment or people!
Liquid and solid particles or dust must not enter the pump. Install the
adequate filters, separators and/or condensers. In case of doubt consult
Leybold.
The intake line of the pump must never be connected to a device with over
atmospheric pressure. Design the exhaust line so that no pressure higher
than 1,15 bar abs. (0,15 bar rel.) can occur. The pressure regulation device is
to be installed by the end-user. We recommend also to collect the pump
exhaust and to treat the gases in function of their nature.
Operating of the pump without oil or operating with incorrect direction of
rotation can destroy the pump.
Never use discarded seals. Always assemble using new seals.
Respect the instructions concerning environment protection when discarding
used oil or exhaust filters!
The pump must be packaged in such a way that it will not be damaged during
shipping, and so that no harmful substances can escape from the package.
We reserve the right to alter the design or any data given in these Operating
Instructions. The illustrations are not binding.
It is mandatory that these operating instructions be read and
understood prior to the vacuum pump installation and start-up.
We reserve the right to alter the design or any data given in these Operating
Instructions. The illustrations are not binding.
Caution: hot surface! In normal operation, the pump surface temperature can
reach 85°C. There is a risk of burning. Switch off the pump and let it cool
down before any intervention or take appropriate precautions. It is
recommended to use an oil casing or pump touching protection at high
ambient temperatures.
As a touching protection, you can use the “Noise enclosure” P/N
960331NENC or 960560NENC. The noise enclosure is an accessory not
included in the pump delivery.
All work on a pump which is “still warm from operation” should be done only
whilst wearing protective gloves.
Handle the pump only while vented and after having let it cool down.
Never remove the oil-fill or oil-drain plugs while the pump is running. There
exists the risk of suffering burns. Always wear protective gloves and protec-
tive goggles also for protection against the oil.
