Important notes concerning the operation of
the exhaust waste vapor condenser
➨
Connect the exhaust to a suitable treatment system to
prevent the discharge of dangerous gases and vapors
to the surrounding atmosphere.
+
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. 46) 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 catchpots
or collecting flask in time to avoid overflow. Install a level
sensor (see “Accessories”, pg. 46; a CVC 3000 or VNC
2 controller is required for operation) for monitoring, if nec-
essary.
