Additional Disinfection Requirements
In addition to the routine cleaning and disinfection tasks listed in the previous table,
additional disinfection is required for the following situations:

Each time the water treatment system is disinfected
When the water treatment system and distribution piping are disinfected, each dialysate
delivery machine should be placed in the Rinse program to draw disinfectant into the
machine through the inlet lines. Check for residual disinfectant prior to use for dialysis.

After contamination of transducer protector
Disinfect the connectors and replace the internal transducer protector if there is
evidence of leakage past the external transducer protector on the venous or blood pump
modules. Disinfect associated parts.

After a dialyzer blood leak
The machine should be disinfected prior to the next treatment if a blood leak alarm
occurred.
Warning! The protocol for disinfection is determined by the facility and its medical
director. When chemicals are used internally, machines must be thoroughly rinsed and
tested for residual disinfectant before using the machine for treatment. Follow the
instructions of the chemical manufacturer for residual testing. If the machine is chemically
disinfected daily, we recommend that it also be heat disinfected at least once per week.

Description
The Chemical / Rinse button runs a program that disinfects the
hydraulic system using a chemical disinfectant followed by an
immediate water rinse to clear the system of residual disinfectant.
The Chemical / Rinse program should be used when disinfecting
with corrosive chemicals, such as bleach, that could damage the
hydraulic components if left in contact for prolonged periods.
The Chemical / Dwell program is designed for disinfecting the
hydraulic system using a non-corrosive chemical disinfectant, such
as formaldehyde. This program is intended for use with chemicals
that are not harmful to the internal components after prolonged
exposure and, hence, do not require the system to be rinsed with
water immediately afterward.
Clean and disinfect bicarbonate concentrate jugs and suction cap
wands per facility protocol.
