T- 1.1.5 CHECK 'ACTUAL' TEMPERATURE
a) Place a calibrated external Temperature meter into the dialysate lines.
IMPORTANT!
b) ASSURE the shunt door is closed and flow through the external flow indicator!
c) Allow the meter to stabilize. Is it reading greater than 35.5° C?
Yes See procedure number
No a) CAREFULLY return NTC# 3 and Conductivity Cell #7 to their CORRECT distribution board
positions respectively labeled "MON-NTC" and "COND".
b) See procedure number
T- 1.1.6 CHECK 'ACTUAL
a) Allow two minutes for BEFORE continuing!
b) Watch the external meter for one minute and NOTE the highest and lowest values.
c) Does the meter's reading vary greater than +/-
Yes See procedure number T- 1.1.7 (page 98).
No Call debug screen 5. CAREFULLY watch TPRE for one minute. Does it vary greater than +/- 2?
Yes
No
T- 1.1.7 TROUBLESHOOT UNSTABLE TEMPERATURE
Watch the external meter's reading for one minute. If it varies greater than +/-
minutes. Two scenarios:
1) Exceeds 40.5° C at some point: CAREFULLY return NTC# 3 and Conductivity Cell #7 to their
distribution board positions (respectively labeled "MON-NTC" and "COND") then see procedure
number T- 4.0.0
2) Remains less than 40.5° C: CAREFULLY return NTC# 3 and Conductivity Cell #7 to their
distribution board positions (respectively labeled "MON-NTC" and "COND") then see procedure
number T- 6.0.0
T- 1.1.8 CHECK NTC #3
a) CAREFULLY return NTC #3 and Conductivity cell #7 to their distribution board positions respectively
labeled "MON-NTC" and "COND".
b) Allow 30 seconds.
c) From the Home screen, is the machine's Temperature display greater than 33° C?
Yes See procedure number
No Replace NTC #3 (see
T- 1.1.6 (page 98).

TEMPERATURE STABILITY
See procedure number
Proceed according to the external meter's reading (two scenarios):
1) Between 35.5° C and 38.5° C: See procedure number
2) Between 38.5 and 39.9° C: See procedure number T- 7.0.0 (page 121).
