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,

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-
