conductivity (during Service and Rinse) and can be opened and closed manually by pressing the
Mute button for 3 seconds.
12) Turn on the connected dialysis machines in a rinse mode.
When the tank empties the SPD will shut off. Note the time.
13) Turn off the dialysis machines. Turn off the Power Switch/Circuit Breaker on the SPD system.
Switch the Mode Rocker Switch from “Disinfection” to “Service and Rinse” position. Close the Product
to Tank and the Venturi Valves.
14) Allow the disinfectant to soak at least 40 minutes to kill all microorganisms.
15) When it is time to rinse, turn on the system Power Switch and note the time.
16) Manually open the Product Dump Valve.
The Product Dump solenoid Valve will open because of the high product conductivity of the
product water. However it will close again as the conductivity falls. For faster rinse the Product
Dump Valve must remain open.
17) Open the flush valve as much as possible (without letting the machine shut off due to low pump inlet
pressure) to hasten the initial rinse.
The progress of the rinsing is indicated by the product water conductivity falling relative to what it
normally is.
18) After the product conductivity is within 1 or 2 microSiemens/cm of the normal value, close the Flush
Valve.
19) Open the Annulus Drain Valve for about 1 minute.
20) Cycle the Pump Vent Valve open for about 2 minutes.
21) Wait another 10 minutes and close the Product Dump Valve.
This will rinse out the distribution loop and product pressure regulator circuit but will, after a
delay, temporarily cause the product conductivity to rise.
22) Turn on the attached dialysis machines. Note the product water conductivity.
Now to rinse the disinfection tank and fluid paths to and from it.
23) Open the Product to Tank Valve for 30 seconds.
24) Push the Fill Tank pushbutton.
25) When the tank fills up with product water and shuts off the solenoid, once again put the mode
switch in “Disinfection.”
