T- 1.0.8 VERIFY TEMPERATURE PROBLEM
Depending on where the problem was originally observed, (i.e. Dialysis or Heat Disinfect), proceed
accordingly:
Dialysis:
Call the Home screen and proceed accordingly (two scenarios).
1. Very unstable and exceeds 41° C at some point: See procedure number
100).
2. NEVER exceeds 41° C: See procedure number
Heat Disinfect:
1. After five minutes, remains less than 35° C:
Dialysis program (remember to press the 'CONFIRM' key) then see procedure number
(page 96).
2. After thirty minutes, is greater than 35° C but fails to reach 80° C:
to Heat Disinfect Program then see procedure number
3. Exceeds (but does not remain) 91° C: See procedure number
4. "TEMP OVER 95 DEGREES" message:
a) Turn the machine off and allow three minutes.
b) Place the machine into DIALYSIS program (remember to press the "CONFIRM' key).
c) See procedure number
T- 1.0.9 CHECK DISPLAYS
a) Before continuing, from the Home screen, it is VERY
important that Temperature is NEVER reaching 41° C
otherwise machine damage may occur!

b) Place the

OLC set, into the
left, labeled "MON-NTC". This is pre-dialyzer
temperature sensor (NTC #3).
c) Referring to the Figure (right), place the
pre-dialyzer conductivity cell's (#7) distribution board position labeled "COND" (5
the left).
d) Post a note that the resistor plugs are in. When troubleshooting is complete they MUST be removed!
e) From the Home screen, is Temperature between 35.1 and 38.9° C?
Yes See procedure number
No a) Per procedure number
correctly at distribution board position labeled "MON-NTC"!
b) Turn the HEATER Switch OFF (rocker switch pressed in towards "0" or "OFF").
c) Leaving the resistor plug installed see procedure number
