Important notes
l
In the application area of medical suction devices, the vacuum is normally quoted as the
difference (in absolute figures) between the absolute pressure and the atmospheric pressure or as negative values in kilopascals (kPa). The indication, e.g. of -10 kPa, in this
document therefore always refers to a pressure level in kPa below the ambient atmospheric pressure.
Rechargeable battery: charge the battery before use.
Use in accordance with the instructions
ll
The device is highly suitable for the aspiration of surgical fluids, secretions, tissue (including bone) and infectious particles. In the emergency room, the doctor’s practice, the
ward or in the home care area.
Guarantee
lll
2 years guarantee on the device from delivery date – 6 months on rechargeable battery
and Quatroflex™ suction unit. The manufacturer is not liable for any damage or consequential damage caused by incorrect operation, inappropriate usage as well as use by
unauthorized persons.
Service work
lV

Disposal
XlV
Before disposal, the device is to be rendered unusable and it must be disposed of in
accordance with the local regulations. Must not be disposed of together with household refuse. Hand the discarded device to a local collection and recycling centre for
old electrical and electronic appliances. Incorrect disposal can have harmful effects on
the environment and public health.

Safety-related checks
XV
For the safety-related checks, it is assumed that the device is maintained and repaired
throughout its service life strictly and exclusively in compliance with these service instructions by authorized service centres
For the Vario as a device in protection class II (EN IEC 60601-1, A1, A2:1995), the safety-related checks are confined to visual inspection of the housing and mains power cord
for damage. This check must be performed prior to each use.
Devices of protection class II do not have a protective earth conductor; there is therefore
no need to check the earth leakage current!
The Vario enclosure is made entirely of insulating material. Tests of the
enclosure leakage
current
using common measuring instruments will therefore not reveal measurable values.
The applied parts of the Vario (type B or CF) are connected to the Vario via non-conductive
vacuum hoses, collection jars and intermediate tubings.
Even when suctioning a conductive fluid until the overflow protection device activates
(9 g/l NaCl; EN ISO 10079-1;1999), measurements of the
patient leakage current using
common measuring instruments will not reveal measurable values.
The Vario pumps do not have patient circuits, signal input and output parts and functional
earth connections.
