SECTION 4 - TEMPERATURE PROBLEMS
NOTE! Temperature does not change instantaneously. Observe all stated times to avoid error!
A) Figure right, ENSURE the Heater Switch is in the “1” or “ON”
position!
B) External leaks, “No Water” and Flow Error alarms cause
temperature problems. If any of these occur at ANY TIME
address them FIRST!
C) Depending on what Program the problem is occurring in, TWO
(2) possible scenarios below:
1) IF in Dialysis Program i.e. connected to concentrate: See parts a AND b below:
a) From the Home screen, ENSURE [Dialysate Flow] is on* AND set to 800 ml/min.
* If [Dialysate Flow] is blinking flow is off! Flow MUST be on!
b) ENSURING the Heater Switch and Dialysate Flow has been on for six (6) minutes if the
temperature problem still exists see procedure number T- 1.0.0 (page 233).
2)
IF in Heat Disinfect: THREE (3) possible scenarios i) or ii) or iii) below:
i) IF (and ONLY if) the “TEMP OVER 95 DEGREES” banner occurred: A) Turn the machine
off then back on; B) RETURN TO DIALYSIS PROGRAM (“Select Program” → ‘Dialysis’ →
‘Enter’)! C) From the Home screen set [Dialysate Flow] to 800 ml/min and press ‘Enter’;
D) See procedure number T- 1.0.0 (page 233).
ii) IF the Heater Switch was “OFF”: Allow twenty (20) minutes ENSURING a Flow Error soe not
occur! If [Temperature] does NOT increase to more than 80° C see scenario iii below.
iii) ALL OTHER scenarios: ENSURING Heat Disinfect has been running for at least twenty (20)
minutes, with the shunt door CLOSED, no leaks AND no Flow Errors! TWO (2) possible
scenarios:
1) IF (and ONLY if) [Temperature] REMAINS more than 80° C AND the [Remaining
Time] window has ‘frozen’ at less than one (1) minute: ENSURING no external
leaks, TWO (2) possible bad components: Component #1: Power Logic Board OR;
Component #2: Functional Board.
2) ALL OTHER scenarios: See parts a THROUGH d below:
a) Plug into acid and LIQUID bicarbonate.
b) RETURN TO DIALYSIS PROGRAM (“Select Program” → ‘Dialysis’ → ‘Enter’)!
c) From the Home screen, set [Dialysate Flow]* to 800 ml/min and press ‘Enter’.
* If [Dialysate Flow] is blinking flow is off! Flow MUST be on!
d) See procedure number T- 1.0.0 (page 233).
