page 4 of 35 Safety information! Important information! + Keep this manual complete and accessible to personnel at all times! + Read this manual carefully before installing or operating the equipment. Observe the instructions contained in this manual. + Do not modify the equipment without authorization. NOTICE This manual is an integral part of the equipment described therein. It describes the safe and proper use of the vacuum pump.
page 5 of 35 ➨ DANGER indicates a hazardous situation which, if not avoided, will result in death or serious injury. + WARNING indicates a hazardous situation which, if not avoided, could result in death or serious injury. NOTICE • CAUTION indicates a hazardous situation which, if not avoided, could result in minor or moderate injury. NOTICE is used to address practices not related to per� sonal injury.
page 6 of 35 General information ☞ Read and comply with this manual before installing or operating the equipment. ☞ Before operating the equipment read and comply with the section ”Cleaning and decontamination”! NOTICE Remove all packing material, remove the product from its packing-box, remove the protective covers from the inlet and outlet ports and keep, inspect the equipment.
page 7 of 35 Setting up and installing the system • Comply with maximum permissible pressures and pressure differences; see section ”Technical data”. Do not operate the pumping unit with overpressure at the inlet or outlet. NOTICE Provide a firm level platform for the equipment. Ensure a stable position of the equipment.���������������������� Ensure that hose con� nections are mechanically stable.
page 8 of 35 Operation conditions ➨ The devices have no approval for operation in or for pumping of potentially explosive atmospheres. ➨ The devices are not suitable to pump: - unstable substances and substances which react explosively under impact (mechanical stress) and/ or when being exposed to elevated temperatures without air, - self inflammable substances, - substances which are inflammable without air and - explosive substance ➨ The devices have no approval for operation below ground.
page 9 of 35 ➨ Use appropriate safety work materials and methods if necessary, e. g., steam sterilization, sterilization indica� tors or germicides. For notes concerning the steriliza� tion of wetted parts, see the “Technical Data” section and “Cleaning and decontaminating”. It is the user´s responsibility to ensure effective sterilization. ☞ Check the collecting bottle regularly for cracks. Do nev� er use a collecting bottle with cracks nor expose it to vacuum.
page 10 of 35 •������������������������������������������������������ ����������������������������������������������������� Use the system only in combination with the integrat� ed hydrophobic filter (sterilizable) to protect equipment and environment (people). NOTICE Maximum liquid level in collecting bottle: approx. 80%, depending on the application. (When working with lowboiling liquids, or liquids that tend to foam, the maximum liquid level might be reduced).

page 16 of 35 During operation ☞ Max. ambient temperature: 40 °C max. 40°C ✔ NOTICE • Use the system only with the integrated hydrophobic filter to protect the vacuum sup� ply from aspirated liquids and aerosols, and to protect the environment/user from con� tamination risk. The mechanical vacuum control provides the vacuum in the bottle in a range of 150 mbar (minimum switching off pressure) to 500 mbar (maximum switching on pressure) for aspiration.
page 17 of 35 Attention: Removing the connection tubing from the screw cap, the filter or from the inlet of the vacuum controller leads to immediate venting of the collecting bottle! Filtration Connect the suction flask to the bottle head.
page 18 of 35 Filter and collecting bottle The hydrophobic filter retains water and aqueous solu� tions also in the form of aerosols. When using solvents or due to evaporation of water, formation of condensate at the outlet of the BVC is possible. NOTICE ☞ Important: Comply with applicable regulations when disposing of solvents. ☞ Attention: Do not remove connections in case of liq� uid in the tube. Do not touch contaminated parts when removing the screw cap.
page 19 of 35 Emptying the collecting bottle max. 80% atmospheric pressure Check liquid level in the collecting bottle regu� larly. Maximally admissible liquid level in collecting bottle: approx. 80 %, depending on the application. (In case of low boiling liquids or in case of suction of liquids which tend to foam, the admissible liquid level might be reduced.) Vent the system. Remove the connecting tube from the filter, iso� late connections in case. Remove screw cap from the collecting bottle.
page 20 of 35 Cleaning and decontaminating Autoclaving The collecting bottle with bottle head and screw cap, the quick coupling and the filter are des� ignated for steam sterilization at 121°C and 2 bar absolute (1 bar overpressure). Time of ex� posure according to DIN 58946 te = 20 minutes. isart® 20 Mid0 µm PTF00 E 0.2 IN sartorius stedim NOTICE Prior to autoclaving loosen or remove the bottle head from the bottle.
page 21 of 35 Important notes on use of disinfectants BVC basic Chlorine bleach BVC basic G Chlorine bleach Aggressive disinfectants which release chlorine or oxygen radicals, e.g., sodium hypochlorite (chlorine bleach) or peroxide compounds can corrode the material of the 4l polypropylene collecting bottle and other components (e. g., couplings). This may lead to stress cracks and breakage of the 4l polypropylene bottle.
page 22 of 35 Sekusept® Plus The use of the disinfectant Sekusept® Plus (Manufacturer: Ecolab GmbH & Co OHG, Düs� seldorf, Germany) in extensive in-house test� ing did not cause any damage to the collect� ing bottle. Hence the disinfectant Sekusept® Plus - even when used in the collecting bottle during suction - is preferred to chlorine bleach.
