unnecessary. Operating the pump without gas ballast in-
creases the solvent recovery rate at the exhaust waste
vapor condenser.
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 (15) at the
exhaust waste vapor condenser (11) regularly; replace
if necessary. Check especially for deterioration, coales-
cence 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. 40)
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 the
separators (collecting flask at the outlet, and in case sepa
-
rator at the inlet) during operation. Check the liquid level
regularly. Do not allow the separators to overfill.
