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 tubing cannot become blocked
to avoid a risk of bursting!
+
Keep the electrical power cord away from heated sur-
faces.
+
Keep the electrical power cord away from hot surfaces.
• 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 sec-
tion “Technical data”, pg. 24”. 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.
• Ensure that the coolant outlet pipe is always free and
that it cannot get blocked. If installing an optional cool-
ant valve, it must always be in the supply line of the
exhaust waste vapor condenser.
Make sure ventilation is adequate to maintain recommend-
ed operating temperature. Keep a minimum distance of
