1. Highest minus lowest less than 70: Displayed Conductivity is stable. See procedure number
CO- 10.0.0 (page 152) to continue troubleshooting OLC problems.
2. Highest minus lowest greater than 70: CAREFULLY watch TPRE for one minute and note the
highest and lowest values. Is highest minus lowest less than 15 (i.e. 0.15° C)?
Yes Conductivity is unstable. See procedure number
No Proceed to page 94, procedure number
CO- 3.5.0 CHECK CONDUCTIVITY AT OTHER FLOW RATES
Check Conductivity stability for other applicable Dialysate flow rates as described below. Read steps a
through f before continuing!
a) From the Home screen, set Dialysate flow to the desired rate then press the 'CONFIRM' key.
b) Re-check loading pressure at each flow rate. If (and ONLY if) it is NOT 'okay' (per
proceed to page 18, procedure number
c) Allow five minutes for stabilization at flows greater than 200 ml/min. If flow is set to 200 ml/min or less
allow 15 minutes.
d) Call debug screen 0 AND while waiting for stabilization, CAREFULLY watch Flow Error. If (and ONLY
if) Flow Error = 1 (intermittently or constant) proceed to page 14,
DIALYSIS PROGRAM
WATER.
e) Call the Home screen if Conductivity is not remaining stable see procedure number
142).
f) Repeat parts a through f for all applicable flow rates. If Conductivity remains stable do NOT continue!
CO- 4.0.0 CHECK CONCENTRATE INLET SYSTEMS
a) Proceed accordingly (based on if using Jjgs or Central Delivery (SDS)):
1) Using Jug(s):
ASSURE the jug(s) are full and the pickup wand(s) are fully submersed. If not this
may be the problem!
ASSURE concentrate connector(s) are inserted tightly into the pickup wand(s). If
not this may be the problem!
2) Using central delivery (SDS):
ASSURE the concentrate connector(s) are inserted tightly into the SDS outlet port(s).
If not this may be the problem!
ASSURE adequate flow from the station valve(s). If not this may be the problem!
b) See procedure number
CO- 4.1.0 CHECK CONCENTRATE INPUT
a) Place the machine into Rinse program for 20 seconds (to assure the pumps are primed).
b) Call debug screen 1. Watch NO EOS AND ALWEOS for 30 seconds. If (and ONLY if) either = 1
proceed to page 161,
c) Connect to concentrate and return to Dialysis program (remember to press the 'CONFIRM' key).
d) Is AIR FREE concentrate drawn steadily in one direction now?
F- 2.0.4.
