Shutdown:
Short-term:
Has the pump been exposed to condensate?
☞
Allow the pump to continue to run at atmospheric pressure for a few minutes (con-
tinuous pumping at a setting of 60).
Has the pump been exposed to media which may damage the pump materials or forms
deposits
?
☞
Check and clean pump heads if necessary.
Has the pressure transducer been exposed to media which may form deposits?
☞
Clean pressure transducer if necessary.
Long-term:
➨
Take measures as described in section short-term shutdown.
➨
Separate pump from the apparatus.
➨
Close inlet and outlet port (e. g. with transport caps).
➨
Store the pump in dry conditions.
In case of low boiling solvents when the formation of condensate is unlikely, the use of
gas ballast might be unnecessary.
☞
Operating the pump without gas ballast increases the solvent recovery rates at the
exhaust waste vapour condenser.
In case of
condensation:
➨
Check liquid level in both catchpots during operation. Avoid overflowing of the catchpots.
☞
Do not overfill the catchpots. Maximum liquid level approx. 80%, to avoid problems
when removing the catchpots.
➨
Check liquid level in both catchpots regularly and drain catchpots in time.
Removing the catchpots
:
Catchpot at outlet:
➨
Remove joint clip, remove catchpot and drain condensate.
Catchpot at inlet:
➨
Admit air or inert gas (via inlet of pumping unit) to atmospheric pressure. Remove
joint clip, remove catchpot and drain condensate.
➨
Reassemble drained catchpots.
Important:
Comply with regulations when disposing solvents/condensates. Reuse if
possible, purify if contaminated.
Attention: Notes concerning the operation of the exhaust waste vapour condenser
➨
Check hose connections prior to starting operation of the cooling system.
➨
Check coolant hoses regularly during operation.
☞
Ensure that the
coolant outlet pipeline
is always free and that it cannot get blocked.
☞
Maximum permissible coolant pressure at the exhaust waste vapour condenser:
6 bar (absolute)
☞
Comply with the maximum permissible coolant pressures of additional components
in the coolant circuit (e.g coolant valve).
☞
Avoid overpressure in the coolant circuit (e.g. caused by blocked or squeezed cool-
ant hoses).
☞
Permissible range of coolant temperature at the exhaust waste vapour condenser:
-15°C to +20°C
☞
The gas outlet (hose nozzle 10 mm) must not be blocked. The exhaust pipeline has
always to be free and pressureless to enable an unhindered discharge of gases.
☞
Connect the exhaust to a suitable treatment plant to prevent the discharge of dan-
gerous gases and vapours to the surrounding atmosphere.
