• We strongly recommend installing an optional coolant
valve (see ”Accessories”, pg. 48) in the supply line
of the exhaust vapor condenser to save water and re-
duce the risk of water spill.
• Avoid overpressure in the coolant circuit (e.g., caused
by blocked or kinked coolant hoses).
In case of condensation: Check the liquid level in both
catchpots (9) during operation. Check the liquid level in
both catchpots regularly. Do not allow the catchpots to
overfill. Drain catchpots in time to avoid overflow. Install a
level sensor (see ”Accessories”, pg. 48) for monitoring,
if necessary (VACUUBRAND controller CVC 3000 or VNC
2 is required).
The maximum liquid level is at approximately 80% of the
total filling level to avoid problems when removing the
catchpots.
Permissible range of coolant temperature at the exhaust
waste vapor condenser: 5 °F to 68 °F (-15°C to +20°C)
Check hose connections prior to starting operation of the
cooling system.
Check coolant hoses regularly during operation.
Removing the catchpots:
Catchpot at outlet:
Remove joint clip. Remove catchpot and drain conden-
sate.
Catchpot at inlet:
Admit air or inert gas (via the pump inlet) to restore at-
mospheric pressure in the catchpot before attempting
removal. Remove joint clip. Remove catchpot and drain
condensate.
Reattach drained catchpots.
