NOTICE
Removing the catchpots:
Catchpot at outlet:
Remove joint clip, remove catchpot and drain condensate.
Round bottom flask at inlet:
Admit air or inert gas (via inlet of pumping unit) to atmospheric pressure. Remove
joint clip, remove catchpot and drain condensate.
Catchpot at inlet (PC 301x VARIO):
Admit air or inert gas (via inlet of pumping unit) to atmospheric pressure. Open drain
screw and drain condensate.
➨
Reassemble drained catchpots.
Important: Comply with regulations when disposing of solvents/condensates. Re-
use if possible, purify if contaminated.
Attention: Notes concerning the operation of the exhaust waste vapour condenser
☞
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
dangerous gases and vapours to the surrounding atmosphere.
☞
Ensure that the coolant outlet pipeline is always free and that it cannot get
blocked.
• Check the overpressure safety relief device at the exhaust waste vapour conden-
ser regularly, replace if necessary. Check especially for conglutination and cracks.
• Maximum permissible coolant pressure at the exhaust waste vapour condenser:
6 bar (absolute)
• Comply with the maximum permissible coolant pressures of additional compo-
nents in the coolant circuit (e.g coolant valve).
• Install coolant valves always in the supply line of the waste vapour condenser only.
• Avoid overpressure in the coolant circuit (e.g. caused by blocked or squeezed
coolant hoses).
• In case of
condensation: Check liquid level in both catchpots during operation.
Avoid overflowing of the catchpots.
Do not allow the catchpots to get overfilled. Maximum liquid level approx. 80%, to
avoid problems when removing the catchpots.
Check liquid level in both catchpots regularly and drain catchpots in time. In case,
install level sensor (see “Accessories“).
Permissible range of coolant temperature at the exhaust waste vapour condenser:
-15°C to +20°C
Check hose connections prior to starting operation of the cooling system.
Check coolant hoses regularly during operation.
