➨
Prevent the discharge of dangerous gases and vapors
to the surrounding atmosphere. If appropriate, connect
the exhaust line to a suitable treatment system.
+
Never block the gas outlet ((2) hose nozzle for tubing
I.D. 3/8” (10 mm)). The exhaust hose has always to be
unobstructed and without back pressure to enable an
unhindered discharge of gases and protect the pump
valves from damage.
•
Note
: Install the hoses of the cooling system in a way
to avoid the flow / dripping of condensed water onto the
pumping unit (especially cables and electronic parts, see
also IP degree of protection, “Technical data”, pg. 28.
• Ensure that the
coolant outlet tubing
is always unob-
structed and that it cannot get blocked.
• Maximum permissible coolant pressure at the exhaust
waste vapor condenser: 87 psi (6 bar) absolute. Outlet
flow must always be unhindered.
• Comply with the maximum permissible coolant pres-
sures of additional components in the coolant circuit
(e.g., coolant valve).
• Avoid overpressure in the coolant circuit (e.g., caused
by blocked or squeezed coolant hoses).
• Only install the optional coolant valve in the supply line
of the exhaust waste vapor condenser.
During operation
➨
Vent and dispose of
potentially dangerous gases or
vapors
at the outlet of the pump appropriately.
+
Due to the high compression ratio, the pump might
generate overpressure at the outlet. Check pressure
compatibility with system components (e.g., exhaust
tubing or exhaust valve) at the outlet. Ensure that the
pump outlet is neither blocked nor restricted.
