OVER- 5.0.0 ISOLATE VALVE #39 (Slow Overflow)

b) The deaeration gauge is used next. ENSURE it reads 0 inHg before installing it!
c) Per the Figure below, tee the gauge between the inlet (clear tubing) and the deaeration pump's input
nozzle.
d) Return the concentrate connectors to their rinse ports
IMPORTANT! Place the machine into RINSE!
e)
1)
IF (and ONLY if) pressure is between 0 and negative (-)12 inHg. Valve #39 is okay! See
