9.4.5 Disinfect Incoming Water Line
It is suggested that the incoming water line be disinfected at
Instrument installation and then as required (or at least every three
months). Baxter recommends that regular cultures be taken of the
dialysate to ensure that the bacterial level in the dialysate is
acceptable. See Section 9.10.1.2.
WARNING
For Instruments with On-Line Hemodiafiltration and or
dialysate filters, the filters must be removed and
bypassed with shunt fittings prior to this procedure.
