T- 6.6.0 VERIFY INCOMING WATER SOURCE

Is the machine connected to the: 1) SAME water source as other currently RUNNING machines that
have good stable temperature OR 2) Its OWN water source, possibly a portable RO. TWO (2) possible
scenarios:
1) IF (and ONLY if) connected to the SAME water source as other machines: See procedure
number T- 6.8.0 (page 300).
2) IF connected to its OWN water source: Using a calibrated temperature meter check the incoming
water temperature (i.e. from the RO). If NOT between 10 and 33° C (50 and 86° F) this may be the
problem! If (and ONLY if) between 10 and 33° C see procedure number
T- 6.8.0 CHECK / ROTATE HEATER
Turn the machine OFF!

c) Replace the heater if badly discolored or if
corrosion or pitting is located.
d) Rotate the heater 180° and reinstall it.
Tighten BOTH* bracket screws evenly!
The heater MUST be positioned perfectly
vertical to maintain proper flow geometry.
* A missing screw or mounting nut may be the problem!
e) Return to Dialysis Program ("Select Program" → 'Dialysis' → 'CONFIRM')!
f) Allow ten (10) minutes before continuing to part g.
g) If Temperature instability continues, changes more than 0.2 °C per minute, see procedure number
T- 6.9.0 (page 300).
