CLEAN- 3.0.2 CHECK VERR IN HEAT DISINFECT (VALVE #39)
a) Turn the machine off then back on (to reset VERR).
b) Place the machine into Heat Disinfect and (IMPORTANT!) allow three minutes.
c) Call debug screen 1. Is VERR greater than 5?
Yes NOTE the machine is in HEAT DISINFECT then proceed to page 81,

No See procedure number
CLEAN- 3.0.3 CHECK VERR IN HEAT DISINFECT (VALVES #43, #29)
IMPORTANT! Allow four minutes so that all valves cycle open! Is VERR greater than 5?
Yes NOTE the machine is in HEAT DISINFECT then proceed to page 81,

CLEAN- 4.0.0 VERIFY RECIRC FLOW (VALVE #29)
CAUTION! If the machine is in HEAT DISINECT hydraulic tubing, fluids and surfaces are hot!
a) To prevent external leaks open the UF sample port and direct the tubing output into a bucket.
b) Call debug screen 0.
c) Referring to the Figure (right), CAREFULLY watch valve
#29's adjacent dot. It may be REMAINING blue or it may be
cycling from white to blue approximately every 100 seconds
and, in this event, valve #29's dot is blue for 9 seconds
ONLY.
d) When the dot is blue valve #29 is supposed to be open. Proceed accordingly:
Valve #29 dot blue constant: See procedure number
Valve #29 dot cycling between white and blue: See procedure number
CLEAN- 4.1.0 CHECK VALVE #29 (ON CONSTANT)
Referring to the Figure (right), is the external flow indicator's (#75) 'bob' rising at least ¼
way up?
Yes See procedure number CLEAN- 5.0.0 (page 76).
No This procedure checks if valve #29 is opening. Referring to
75) a syringe, with a piece of tubing attached, that will fit snugly onto valve
#29's input nozzle is required:
a) Referring to
#29's nozzle.
b) Attach the syringe tubing to the empty nozzle. If the valve is open you should be able
EASILY push through it with no resistance (three scenarios):
