Warning
3.8
Removing the pump from the system
Shut down the pump and vent as described in Sections 3.5 and 3.6.
If the pump has previously handled hazardous gases, implement the pro-
per precautionary measures before opening the intake or exhaust connec-
tion.
If necessary, use gloves, a respirator and/or protective clothing and work
under an exhaust hood.
Disconnect the pump only when it has come to a full stop. The green LED at
the frequency converter must have gone out.
Then switch the mains power off and wait until the yellow power LED is off.
Then only disconnect any cable connections.
The pumps may be contaminated with process gases. These gases may be
toxic and hazardous to health. In addition, deposits with similarly dangerous
properties may have formed. Many of these gases and deposits form acids
when they come into contact with humid air. This will result in serious corro-
sion damage to the pump.
To avoid health hazards and corrosion damage when the pumps are
detached from the system, fasten a container of desiccant under the trans-
port cover of the high-vacuum connection and then close the pump imme-
diately at all flange connections. Store the pump, with a desiccant, in an air-
tight PE bag.
Corrosion damage due to faulty packing will nullify the guarantee.
Pack the pump so that it cannot be damaged during shipping and storage.
Pay particular attention to protection for the flanges and the electrical plug.
Observe the instructions in Section 4.2 if you forward the pump to Oerlikon
Leybold Vacuum.
