F- 7.0.9 CHECK FLOW FROM THE BALANCING CHAMBERS
a) Reattach the tubing to valve #26.
b) The "Select Program" screen MUST still be up!
c) Valve #37 MUST remain plugged into valve 30's distribution board position ("V30")!
d) Referring to Figure 17
e) Remove the clamp and measure flow from the tubing for 30 seconds. Greater than 400 ml?
Yes a) Clamp and reattach the tubing to the conductivity cell.
b) See procedure number
No a) CAREFULLY return valve #37 to its distribution board position.
b) CAREFULLY return valve #35 to valve #30's distribution board position (labeled "V30" or
"P30").
c) Measure flow from the tubing for 30 seconds. Greater than 400 ml?
F- 7.1.0 DETERMINE DIASAFE
a) IMPORTANT! Remove the clamp at the conductivity cell's tubing.
b) How to proceed depends on if the machine is equipped with a DiaSafe

F- 7.2.0 CHECK FLOW FROM TEST VALVE #91 (Old Style DiaSafe
a) Check for restrictions in the tubing between conductivity cell #7 and the DiaSafe
b) If no restrictions are located, referring to
'Common') Port of Test Valve #91 to the DiaSafe
c) Remove the quick connector and measure flow from it for 30 seconds. Greater than 400 ml?
Yes Replace the DiaSafe
No Test valve #91 or its tubing is restricted.
(page 36), clamp and remove the tubing at conductivity cell #7.
F- 7.1.0
Yes CAREFULLY return valves #30 and #35 to their distribution board positions
then return to procedure number
No Assuming that above procedures were performed correctly, it appears that
valves #31 and/or #33 and/or #35 and/or #37 are restricted or the actuator
board or actuator cable is bad.
