F- 3.2.0 SIX HUNDRED (600) ML OR MORE IN FILLING PROGRAM
a) Return the Air Sensor’s female connector to
the
5
th
distribution board position from the
left.
b) Call debug screen 0.
If the Air Sensor is
plugged in properly, Chamber #69’s
box says “No Air”.
c) See procedure number F- 3.2.1 (page 42).
F- 3.2.1 CHAMBER #69 = “No Air”
a) This procedure uses a psi gauge. ENSURE it reads 0 psi before installing it.
b) Return BOTH concentrate connectors to their RINSE ports!
c) Figure right, tee the gauge between the Flow Pump's
OUTPUT nozzle and its WHITE tubing.
d)
Tie wrap both sides of the gauge tubing to
prevent leaks and false readings!
e) See procedure number F- 3.2.2 (page 42).
F- 3.2.2 ISOLATE FLOW PUMP
a)
Place the machine in RINSE!
b) Watch for one (1) minute to ENSURE a “No Water” alarm NEVER occurs!
c) Call debug screen 0. If debug does not appear press ‘Escape’ then call screen 0.
d) Allow Valve #43’s ‘dot’ (Figure right) to turn blue then WHITE again! While
white, does pressure CYCLE, about every three (3) seconds, to between 35
and 36 psi?
Yes Between 35 and 36 psi! See procedure number F- 3.3.0 (page 43).
No NOT between 35 and 36 psi! ENSURING the machine was in RINSE AND no leaks, TWO
(2) possible scenarios below:
1) IF (and ONLY if) pressure is too low: DO NOT calibrate instead proceed to
page
93
, procedure number F- 9.0.2 3.
2) IF pressure is too high: Perform parts a AND b below:
a) Per the Figure (above), adjust Valve #78 until pressure cycles to between 35 and 36
psi!
b) See procedure number F- 3.3.0 (page 43).
