Never block the gas outlet ((8) hose nozzle for tubing
I.D. 3/8” (10 mm)). The exhaust hose must always be
unobstructed and without back-pressure to enable an
unhindered discharge of gases.

Check the overpressure safety relief device (17) at
the exhaust waste vapor condenser (13) regularly; re-
place if necessary. Check especially for deterioration,
coalescence and cracks.
• Ensure that the coolant outlet hose is always free
and that it cannot get blocked.
• Maximum permissible coolant pressure at the exhaust
waste vapor condenser: 87 psi (6 bar) absolute
• Comply with the maximum permissible coolant pres-
sures of additional components in the coolant circuit
(e.g., coolant valve).
• We strongly recommend installing an optional coolant
valve (see “Accessories”, pg. 92) 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 (14) or in the collecting flask (20) during op-
eration. Check the liquid level regularly. Do not allow the
catchpots or the collecting flask to overfill. Drain catch-
pots or collecting flask in time to avoid overflow. Install a
level sensor (see “Accessories”, pg. 92) for monitoring,
if necessary.
The maximum liquid level is at approximately 80% of the
total filling level to avoid problems when removing the
catchpots or the collecting flask.
Permissible range of coolant temperature at the exhaust
waste vapor condenser:
5 °F to 68 °F (-15°C to +20°C)
