Water Line Disinfection
This function disinfects the water lines in the reprocessor. The current water quality standard for Washers/Disinfectors
in the United States and Canada recommends the use of potable (human consumption/drinking quality) water as the
supply water for use in washers/disinfectors. If you facility can supply potable quality water to the DSD EDGE
®
automated endoscope reprocessor, you will meet these requirements, so daily disinfection of the water lines and water
filter is not required, as long as the pre-filtration system is installed upstream of the reprocessor and is functioning
properly. Other countries have a more stringent water quality requirement under the standard ISO 15883-4:2008
(Washers-disinfectors Part 4). If you are required to meet this standard, chemical disinfection of the water treatment
(filtration) and delivery system must be performed on a weekly basis and whenever the 0.2 micron bacterial retentive
filter is replaced. This standard requires that all rinse water delivered to the washer/disinfector contain no more than 10
cfu (colony forming units) per 100 ml. Microbiological quality of even potable water varies considerably. If you are
unsure of the microbiological quality of your washer/disinfector supply water, you should have it tested according to
either local or internal guidelines. This procedure must also be performed after each water filter change and after any
service is performed on the water supply system.
Caution!
Ensure the restrictor adapter provided with the installation kit is connected in
the basin before performing this procedure.
