Exhaust line
Connect the exhaust line with a hose to the pump, or when operating the
pump without a connected exhaust line, operate the pump only in a well
ventilated room. The operator must check, whether the pumped gases will
lead to safety risks on the environment if the pump is operated without an
exhaust line (i.e. risk of suffocation, risk of slipping due to condensing
vapours, etc.).
The cross-section of the exhaust line must at least match the inside diameter
of the connections.
Smaller cross sections may cause an undesirable overpressure within the
system. Do not start up the pump with a constricted or blocked exhaust.
Ensure that any valves or blocking devices in the exhaust line are open.
Clogged exhaust lines will reduce the available pumping speed, increase
temperature and cause overloading of the pump motor or a dangerous
overpressure within the system. There is the risk of bursting. The pump
can generate pressures up to 5 bar (abs.) at the exhaust, when the dis-
charge line is shut.
When pumping vapours we recommend connecting a condensate separator
at the exhaust.
The exhaust lines should be laid so that they drop down and away thereby
preventing condensate from flowing back into the pump. We recommend a
slope > 3°.
Connect the exhaust line to an abatement system with sufficient throughput,
if required by the process.
If within the system toxic substances or gases are being used, then the
operator will be responsible for ensuring that the corresponding safety pre-
cautions are introduced!
3.4 Electrical Connection
Read the data on the device nameplate carefully before connecting to mains
voltage. Plug in the power connector.
The pump is only intended for a TN systems network. For other types of net-
works please contact Leybold.
When using a residual current device (RCD) install type B or type F.
The plug is equipped with a cable pull-out protection. When plugging in the
mains plug, the pull-out protection mechanism engages. To pull out, press
finger on the yellow release lever, which will release the locking mechanism
again.
If required, connect the X1 control interface or the X104 RS 485 interface
(see Section 4.2).
