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).
• 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 gen-
erate overpressure at the outlet. Check pressure com-
patibility with system components (e.g., exhaust tubing
or exhaust valve) at the outlet. Ensure that the pump
outlet is neither blocked nor restricted.
+
Maximum ambient temperature
: 104 °F (40 °C)
Check the maximum temperatures, if installing the
pump in a cabinet or a housing. Make sure ventilation
is adequate, especially if the ambient temperature is
elevated.
• If the pump is installed at an altitude of more than 6500
ft (2000 m) above mean sea level, check compatibility
with applicable safety requirements, and adopt suitable
measures. There is a risk of the motor overheating due
to insufficient cooling.
