Check level of liquid in the collecting bottle regularly.
Maximum liquid level in collecting bottle: approx. 80 %, de-
pending on the application (in case of low boiling liquids or in
case of suction of liquids which tend to foam, the maximum
liquid level might be reduced).
Emptying of the collecting bottle:
☞ Switch off pump or isolate pump from system, vent the sys-
tem (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 liquid
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 evapora-
tion of water, condensate may be recovered in the catchpot.
☞ Remove joint clip and catchpot and drain condensate in case.
Important: Comply with applicable regulations when disposing
of solvents.
Change filter if necessary (contaminated, no or bad aspiration,
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.
