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 at least 500 ml/min.
*
If the lamp above the Dialysate Flow on/off is blinking flow is off! Flow MUST be on!
b) ENSURING the Heater Switch and Flow has been on for at least six (6) minutes if the
temperature problem still exists see procedure number T- 1.0.0 (page 215).
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 for two (2) seconds then back on; B) RETURN TO DIALYSIS PROGRAM (“Select
Program”
→ ‘Dialysis’ → ‘CONFIRM’)!
C) From the Home screen, set [Dialysate Flow] to 800
ml/min; D) See procedure number T- 1.0.0 (page 215).
ii) IF the Heater Switch was “OFF”: Allow twenty (20) minutes! 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 AND no leaks! 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’ → ‘CONFIRM’)!
c) From the Home screen, set Dialysate Flow * to 800 ml/min and press ‘CONFIRM’.
*
If the lamp above the Dialysate Flow on/off key is blinking flow is off! Flow MUST
be on!
d) See procedure number T- 1.0.0 (page 215).
