Due to the high compression ratio, the pump may gen-
erate overpressure at the outlet. Check pressure com-
patibility with system components (e.g., exhaust pipe-
line or exhaust valve) at the outlet.
+
Do not permit any
uncontrolled pressurizing
. Make
sure that the exhaust pipeline cannot become blocked.
If there is an exhaust isolation valve, make sure that you
cannot operate the equipment with the valve closed to
avoid a
risk of bursting!
+
Keep the electrical power cord away from heated sur-
faces.
• Provide a firm, level platform for the equipment. Check
that the system which you are going to evacuate is
mechanically stable. Check that all fittings are secure.
Ensure a stable position of the pump without any me-
chanical contact other than the pump feet.
• Comply with
maximum permissible pressures
at in-
let and outlet and with maximum permissible pres-
sure differences between inlet and outlet. See section
„Technical data“, pg. 23. Do not operate the pump
with overpressure at the inlet.
• Avoid overpressure of more than 17.5 psi absolute (1.2
bar absolute) in the event that inert gas is connected to
the pump, to the gas ballast or to a venting valve.
•
Note
: Flexible elements will shrink when evacuated.
• Connect hoses gas tight at inlet and outlet of the pump.
• Ensure that no foreign objects can be drawn into the
pump.
• Check the power source and the pump’s rating plate
to be sure that the power source and the equipment
match in voltage, phase, and frequency.
