Check liquid level in the collecting bottle regularly.
Maximally admissible liquid level in collecting bottle: ap-
prox. 80 %, depending on the application (in case of low boil-
ing liquids or in case of suction of liquids which tend to foam,
the admissible liquid level might be reduced).
Emptying of the collecting bottle:
☞
Switch off pump or isolate pump from system, vent the
system (release VHC). Remove the connecting tube from
the filter, isolate connections in case.
☞
Remove screw cap from the collecting bottle. Remove bot-
tle from the support. Sterilize and dispose of collected liq-
uid according to appropriate regulations.
Attention: Do not remove connections in case of liquid in
the tube. Do not touch contaminated parts when removing
the screw cap. Risk of infection! Wear appropriate protective
clothing, e.g. gloves.
The hydrophobic filter retains water and aqueous solutions
also in the form of aerosols. When using solvents or due to
evaporation of water, condensate may be recovered in the
separator.
☞
Remove separator and drain condensate in case.
Important: Comply with applicable regulations when dispos-
ing of solvents.
Change filter if necessary (contaminated, no or bad aspira-
tion, pressure control device switches without demand of
vacuum).
☞
Use only the original spare part and sterilize and dispose
of the filter according to appropriate regulations.
Note: After disinfection with alcohol allow the filter to dry com-
pletely because the filter may become clogged by alcohol.
Do not remove the
metal fitting at the screw cap.
If the fitting is loose, tighten the fitting carefully from the in-
side.
