(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.
+
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 suit-
able measures. There is a risk of the motor overheat-
ing due to insufficient cooling.
• Check compatibility with the maximally permitted
pressure at outlet and the maximum pressure dif-
ference between inlet and outlet ports.
Do not start the pump if the pressure difference between
inlet and outlet ports exceeds max. 16.0 psi (1.1 bar).
Attempts to start the pump at higher pressure difference
may cause stalling and damage of the motor.
If pumping condensable vapors (water vapor, solvents,
