F- 7.7.20 PART 3 GOOD FLOW / PART 4 LESS THAN 800 ML / RESTRICTED VALVES #38 AND #34
Balancing Chamber Valve #38 and/or Valve #34 is not opening. Also, the Actuator Cable or the distribution
board may be bad. These procedures isolate between these components:
a) Turn the machine OFF.
b) The Flow Pump remains plugged into the Deaeration Pump’s distribution board position.
c)
Per the Figure below, replace Valve #38 with a known good.
d) Plug the new valve #38’s connector into valve #31’s distribution board position, “V31”.
e) ENSURE the bucket with the RED dialyzer connector submersed in it is full!
f)
Turn the machine on but DO NOT press any other keys.
g) With “Select Program” up, measure drain flow, into the cylinder, for one (1) minute. More than 800 ml
every minute?
Yes More than 800 ml! Problem located! The previous valve #38 is bad!
No Less than 800 ml collected! See procedure number F- 7.7.22 (page 95).
