In operation Closed In place Solid Green Solid Blue None Infusate temperature is
≥ 33 °C and < 35 °C None
In operation Closed In place Solid Green Solid or Flashing
Blue >30 seconds None Warmer is unable to
heat the infusate within
operational range. Infusate
temperature is
< 20 °C and/or the flow
rate is > 200 mL/min. Reduce the flow rate if
possible. If there is no
change in operational
temperature, consider
replacing the Warmer and
contact Technical Support.
In operation Closed In place Solid Green Solid Green None Infusate temperature is
≥ 35 °C and ≤ 42 °C None
In operation Closed In place Solid Green Solid Yellow None Infusate (and/or ambient
temperature) is > 42 °C
but less than an Over Temp
condition Observe. This state whereby
the infusate is > 42 ºC
should only be entered
periodically during changes
in flow rate or infusate
temperature.

the Warmer covers open to
stop warming. Replace the
Warmer if this occurs, and
contact Technical Support.
