Loading Pressure 16 Psi Or More - Fresenius Medical Care 2008T Troubleshooting Manual

Loading Pressure less than 16 psi continued:
d) From the Home screen, set [Dialysate Flow] to 800 ml/min and press 'Enter'.
e) Proceed to
DAIR- 2.0.0 LOADING PRESSURE 16 PSI OR MORE
a) This is NOT a routine calibration! Follow the instructions to avoid error!
NOTES: 1) Loading and Deaeration pressure are calibrated until BOTH are in range. LOADING
between 23 and 25 psi; DEAERATION refer to
2) The value in the [Pump Rate] data box determines the speed of the Deaeration Motor
and thus Deaeration pressure! [Pump Rate] should NEVER be set to less than 180!
3) The BYPASS valve, on the Deaeration Pump (see Figure 84 (page 545)), should be
adjusted ONLY if Deaeration pressure is too high when [Pump Rate] = 180.
4) Loading Pressure is mechanically calibrated using Valve #65 (see Figure 84 (page 545))!
5) 'Sharply' press the 'Enter' key after each [Pump Rate] adjustment. The data box MUST
be pale yellow/white (NOT bright yellow or gray!) for the rate adjustment to take effect.
b) Press the [PUMP RATE] data box, it turns bright yellow.
c) Adjust its value, then sharply press 'Enter' ONCE. The box MUST return to pale yellow / white i.e. not
bright yellow or gray!
d) Repeat parts b and c until if target pressures can be achieved?
Yes Target pressures achieved! A) Press 'Enter' to save the calibration; B) Turn the machine off
then on and return to Dialysis Program ("Select Program" → 'Dialysis' → 'Enter'); C) The
Deaeration problem is solved but return to the procedure that prompted you here!
No Target pressures CANNOT be achieved! See procedure number
