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-

patibility with system components (e.g., exhaust tubing
or exhaust valve) at the outlet. Ensure that the pump
outlet is neither blocked nor restricted.
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.
