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)
• 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)
absolute
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.
