Over- 1.0.0 Isolate Central (Sds) Concentrate Delivery System; Over- 1.0.1 Attached To A Central System/Isolate High Pressure (Slow Overflow) - Fresenius Medical Care 2008K2 Troubleshooting Manual

I) If Flow Error EVER = 1, even just once, a masked Flow
Error is occurring! WITHOUT LOOKING AWAY watch it for
three (3) minutes or until it EVER = 1. TWO (2) possible
scenarios:
1) IF Flow Error EVER = 1, even just once! DO NOT troubleshoot overflow instead troubleshoot the
flow error! Refer to the Table of Contents for whatever program the machine is in.
2) IF Flow Error ALWAYS = 0! Is the machine in: i) A Cleaning Program OR ii ) Dialysis Program:
i) IF in a Cleaning Program: Proceed to
ii) IF in Dialysis Program: Perform parts a AND b below:
a) From the Home screen, allow [Conductivity] to increase to more than 12.0 mS.
b) Call debug screen 1. Is FILACT ALWAYS = 1 (Yes or No)?
Yes
No FILACT = 0! See procedure number

OVER- 1.0.0 ISOLATE CENTRAL (SDS) CONCENTRATE DELIVERY SYSTEM

Turn the machine OFF!
a)
b) When the machine is off OR if [Dialysate Flow] is "OFF" and the machine is attached to a Central
Concentrate Delivery System (SDS), over time, SDS pressure too high may force the concentrate pumps

c) Is the red AND / OR blue concentrate connectors currently attached to a SDS system?
Yes Attached to a central system! Allowing up to ½ hour, if (and ONLY if) overflow still occurs see
procedure number
was occurring when attached to a particular station in the clinic where the pressure is too high.
No NOT attached to a central system. If (and ONLY if) overflow is still occurring see procedure

attached to a SDS where the pressure is too high.
OVER- 1.0.1 ATTACHED TO A CENTRAL SYSTEM / ISOLATE HIGH PRESSURE (Slow Overflow)
a) Disconnect the red AND blue concentrate connector(s) from the central supply.
b) Allowing one (1) minute does vent tubing overflow stop?
Yes Overflow stops! Acid and/or bicarbonate central pressure is too high!
No Overflow does NOT stop! See procedure number
FILACT = 1! Proceed to
