2008T Troubleshooting Guide
P/N 490292 Rev. A
F- 18.0.0 LOADING PRESSURE CYCLES TO BELOW 11 psi
a) The following is ESPECIALLY IMPORTANT if the machine was worked on
by someone who may have connected the BALANCING CHAMBER
VALVES (#31 through #38) incorrectly between the distribution board and
their solenoid terminals (Figure right).
b) TWO (2) possible scenarios:
1) IF (and ONLY if) SURE the machine was NOT worked on previously for this Flow
problem: See procedure number F- 18.1.0 (page 138).
2) IF the machine WAS or MAY have been worked on previously: See parts a THROUGH c
below:
a) Leave the machine in Dialysis Program and DO NOT turn Dialysate Flow “OFF”!
b) Figure below, without unplugging valves, CAREFULLY trace the wires from EACH valve to
its SPECIFIC distribution board position. If ANY do NOT terminate properly, at either end,
this most likely is the problem!
c) If (and ONLY if) a wiring error is NOT located see procedure number F- 18.1.0 (page 138).
