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 insufficient cooling.
max. 6500 ft
(2000 m)
• Check compatibility with the
maximally
permitted pressure
at outlet and the
max-
imum pressure difference
between inlet
and outlet ports.
max.
16.0 psi
(1.1 bar)
