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 install-

ing the pump in a cabinet or a housing.

Make sure ventilation is adequate, especial-

ly if the ambient temperature is elevated.

max.

104°F

(40°C)

+ Operation with silencer at the outlet: Oper-

ating the pump at a high inlet pressure or

pumping dusty gases for a long time may

cause clogging of the silencer. Check the

silencer regularly and replace if necessary,

or install a hose nozzle instead.

✔

• If the pump is installed at an altitude of more

than 6500 ft (2000 m) above mean sea lev-

el, check compatibility with applicable safety

requirements, and adopt suitable measures.

There is a risk of the motor overheating due

to insufcient cooling.

(2000 m)

• Check compatibility with the maximally

permitted pressure at outlet and the max-

imum pressure difference between inlet

and outlet ports.
