DIASAFE Plus Filter

This option defines whether or not a Diasafe Plus filter is present in the machine. As some of
the timing of various functions is dependent on the volume in the filter, this option must be
set properly.
HE Leak Test
The HE (Heat Exchanger) Leak Test is available in software versions 2.53 and later. Setting
this option to 'Yes' will run a four minute pressure holding test on the Heat Exchanger after
the Chemical/Rinse program's 45 second pre-rinse.
Clean, Rinse, and Disinfect times
The times for these various programs may be set in the Service Mode.
Extended Pre-Rinse
With this option set to yes, the pre-rinse time for heat disinfect is increased to 20 minutes
with reduced flow and higher fluid temperature through the drain line.
Recirculate Option
If active, a RECIRC GOAL and TIME can be selected. When Recirculation is initiated, the
preselected goal and time with the calculated rate will automatically display on the "Dialysis"
screen and start ultrafiltration.
Prime Amount
A desired prime volume from 100–1000 ml can be selected. This allows Prime to continue
until the selected volume has been delivered (measured by the blood pump speed).
Acid and Bic Alert Default
The operator may use the option to sound an alert when the concentrate jugs are low. This is
setup in the "Dialysate" screen. These default values are set using these parameter entry
buttons.
Max. UF Rate
The maximum UF rate that machine is limited with this selection. The choices are 1000,
2000, 3000, 4000 ml/h.
