Page 70
FRESH SIDE THEORY: Per the Figure below, when ‘Select Program” is up, the top Balancing Chamber (BC) valves (V31 – V34) are supposed to be open, the bottom BC valves (V35 – V38) are closed. V30, V26 and V25 are open. Deaeration Pump #20 is running and can draw from hydrochamber C and D. PART 1 THEORY: Plugging V35 into V30’s distribution board position should open V35.
Page 71
F- 7.3.33 PART 1 BAD FLOW / PART 2 MORE THAN 800 ML / RESTRICTED VALVES #31 OR #35 Balancing Chamber Valve #35 and/or Valve #31 is not opening.
