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 3300
ft (1000 m) above mean sea level, check compatibil-
ity with applicable safety requirements, especially IEC
60034. There is a risk of the motor overheating due to
insufficient cooling.
• Check compatibility with the maximally permitted
pressure at outlet and the maximum pressure differ-
ence 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,
etc.), let the pump run with gas ballast to help purge any
condensation in the pump.
Prevent internal condensation, transfer of liquids or dust.
The diaphragms and valves will be damaged, if liquids are
pumped in significant amounts.
Check the pump regularly for external soiling and depos-
