Function description

The DG 3 is a microprocessor-controlled metering unit for manufacturing ready-to-use
disinfectant for instrument and surface disinfectant. This is a stationary device.
BAM control number: BAM-DDE 27.
4.1 Procedure during the microbiological examination of decentralized
disinfectant metering units
Responsibility for the correct operation of the metering unit in accordance with the RKI
guidelines on "Design criteria, properties and operation of decentralized disinfectant
metering units" (Federal Health Bulletin 2004 . 47: 67-72) rests with the owner.
The technical hygiene checks which are required every year are described in the Operating
and Installation Instructions, chapter
If the end user conducts a test for a situation-related hygienic-microbiological verification of
the metering device, Ecolab suggests the process described in RKI recommendation
"Requirement for hygiene in the cleaning and disinfection of surfaces" (Federal Health
Bulletin 2004-47: 51-61, No. 4.5), this should be done following the process described in
chapter 6.4 "Microbiological examination of decentralized disinfectant metering units -
Maintenance".
