CO- 8.0.0 CHECK CONCENTRATE(S)
a) If removed from a previous procedure, return conductivity cell #7 to distribution board position labeled
th
"COND" (6 position from the left).
b) Check concentrates accordingly:
If using central (SDS) delivery: Swap to a station where a machine has 'normal' conductivity
If using jugs: Swap concentrate(s) with another machine that has 'normal' conductivity
c) From Dialysis program, and with Dialysate flow ON (Dialysate Flow on/off LED off), allow 8 minutes.
Does conductivity become 'normal'?
Yes The previous concentrate supply is bad.
No Two scenarios. Proceed accordingly):
1. Conductivity higher than 'normal': See procedure number
2. Conductivity lower than 'normal': See procedure number
CO- 8.0.2 VERIFY CENTRAL (SDS) DELIVERY SYSTEM
a) Referring to Figure 322
correctly!
b) Excessive central delivery pressure (SDS), greater than 2 psi, may force concentrate through the
concentrate pump(s). Is the machine hooked to a central acid AND/OR bicarbonate delivery system?
Yes See procedure number
No See procedure number
CO- 8.0.3 CHECK CENTRAL DELIVERY SYSTEM(S) FOR EXCESSIVE PRESSURE
a) If using central acid, place the red (acid) connector into a jug filled with acid.
b) If using central bicarbonate, place the blue connector into a jug filled with fresh bicarbonate.
c) Allow 10 minutes. Does conductivity return to 'normal'?
Yes Check the central system(s) for high pressure. NOTE: Installing 6 psi check valves (P/N
150209, white inserts) in the pump(s) INPUT tubing deceases pressure to the pump(s).
No See procedure number
CO- 8.0.4 CHECK VALVE #29
If valve #29 is leaking, conductive dialysate may circulate into the fresh and causes high conductivity:
a) Referring to Figure 61
b) Allow up to 15 minutes. Does conductivity return to a normal?
Yes See procedure number
No See procedure number

(page 150), tightly clamp the input tubing at valve #29.
