T- 1.5.1 [REMAINING TIME] = 0:00
a) Place the machine in HEAT DISINFECT.
b) Is the screen’s TOP [Remaining Prerinse Time]
window = 0:00?
Yes [Remaining Prerinse Time] = 0:00! See procedure number T- 1.5.2 (page 247).
No a) Escape HEAT DISINFECT and place the machine in RINSE!
b) Allow [Remaining Time] = 0:00 BEFORE continuing to part c!
c) Return to HEAT DISINFECT!
d) See procedure number T- 1.5.2 (page 247).
T- 1.5.2 [Remaining Prerinse Time] = 0:00
a) Being aware that flow does not stop, remove the dialyzer connectors from the shunt and connect them
to a calibrated Temperature (°C) meter * but
DO NOT shut the door!
*
WARNING! A NEO-1 meter CANNOT be used! The NEO-2 and other meters, capable of measuring
more than 90° C, can be used! Refer to the meter’s Operator’s manual
b) A “Flow Recirc Error” may occur but MUST go away within forty five (45) seconds!
c) The “Cover is Open” banner appears but the flow indicator’s ‘bob’ MUST be moving up and down!
d) Allow thirty (30) minutes OR until if “TEMP OVER 95 DEGREES” reoccurs.
e) Noting the screen’s [Temperature] window, THREE (3) possible scenarios 1) or 2) or 3) below:
1) IF (and ONLY if) screen [Temperature] = 95° C or more: Proceed to
page 251
, procedure
number T- 1.5.5 .
2) IF (and ONLY if) screen [Temperature] is LESS THAN 95° C BUT “TEMP OVER 95 DEGREES”
reoccurs: Proceed to
page 250
, procedure number T- 1.5.4 .
3) IF screen [Temperature] is LESS THAN 95° C AND “TEMP OVER 95 DEGREES” DID NOT
reoccur: Perform parts A AND B below:
a) A) ENSURING screen [Temperature] remains between 80° C and 92° C, without looking
away, watch it for one (1) minute noting its highest and lowest values.
b) To determine [Temperature] stability subtract the lowest value seen from the highest value
seen. TWO (2) possible scenarios 1) or 2) below:
1) IF (and ONLY if) the result is MORE THAN two (2) i.e. UNSTABLE: ENSURING
“TEMP OVER 95 DEGREES” HAS NOT reoccured see procedure number T- 1.5.3
(page 248).
2) IF the result is two (2) or less i.e. STABLE: The problem is not occurring at this time!
