WARNING
CAUTION
In order for the high-performance condenser to recover solvent
from the transferred gas, it must be cooled with a cold water
connection or a recirculating cooler.
If using a coolant valve:
WARNING
When the pump stops, restore the system to normal atmospheric
pressure (release pneumatic pressure in vacuum pump system).
At appropriate intervals, inspect the fill level in the condensate
tion flask collection flasks located on the suction and pressure sides of the
vacuum pump system (Fig. 2/8 and 9, page 13). When needed,
empty the collection flasks; properly dispose of contents.
Excessive pressure may cause the vacuum pump
system to rupture.
 Do not exceed the maximum permissible operat-
ing pressure (0 bar).
 Monitor pressure during operation.
 If pressure exceeds the maximum permissible
operating pressure of the vacuum pump system:
Immediately switch the vacuum pump system off
and fix the fault (see Chapter 10, page 47).
Danger of high-performance condenser rupturing
The high-performance condenser is not pressure-
proof.
 Make sure that the high-performance conden-
ser's gas outlet is not blocked.
Danger of high-performance condenser rupturing
 Ensure that the coolant valve is installed be-
tween the coolant supply and the coolant inlet
nozzles of the high-performance condenser.
