☞ Provide always a free and pressureless exhaust pipeline.
☞ Ensure that the system design does not allow the coolant outlet pipeline to be-
come blocked. Install an optional coolant valve always in the supply line of the
exhaust waste vapour condenser only.
☞ Check the overpressure safety relief device at the exhaust waste vapour conden-
ser in appropriate intervals.
• Comply with maximum permissible pressures at inlet and outlet and pressure
differences between inlet and outlet, see section ”Technical data”. Do not operate
the pump with overpressure at the inlet.
• Obey maximum permitted pressure at the pressure transducer, see section
”Technical data”.
• Check that mains voltage and current conform with the equipment (see rating
plate).
• Avoid overpressure of more than 0.2 bar in case inert gas is connected.
• Connect pipes gas tight at inlet and outlet of the pump and at the pressure trans-
ducer.
• Secure coolant hoses at the hose nozzles (e.g. with hose clip) to prevent their
accidental slipping.
• Attention: Flexible elements tend to shrink when evacuated.
Provide a firm level platform for the equipment and check that the system to be
evacuated is mechanically stable and that all fittings are secure. Ensure a stable po-
sition of the pump without any mechanical contact except of the pump feet. Comply
with all applicable safety regulations.
Position the CVC 3000 and its vacuum connection lines so that no condensate can
flow towards the pressure transducer.
Keep a distance of minimum 20 cm between fan and ambient parts (e.g. housing,
walls, ...). Check fan regularly for dust/dirt, clean if necessary to avoid a cutback of
ventilation.
If the equipment is brought from cold environment into a room for operation, allow
the equipment to warm up (pay attention to water condensation on cold surfaces).
The diameter of the inlet and outlet pipeline should be at the least as large as the
diameter of the pump connection pipelines.
Comply with all applicable and relevant safety requirements (regulations and
guidelines), implement the required actions and adopt suitable safety meas-
ures.
Ambient conditions
To the best of our knowledge the equipment is in compliance with the requirements
of the applicable EC-directives and harmonized standards (see ”Declaration of con-
formity”) with regard to design, type and model. Directive IEC 1010 gives in detail
conditions, under which the equipment can be operated safely (see also IP degree
of protection). Adopt suitable measures in case of differences, e. g. using the equip-
ment outdoors, installation in altitudes of more than 1000 m above mean sea level,
conductive pollution or bedewing.
Pay attention to the permissible maximum ambient and gas inlet temperatures
(see ”Technical data”).
