4.0 Safety Systems
4.1 Over Temperature Protection
A backup system within the warmer is independent of
the main controller and monitors fluid temperature
continuously. If the output fluid temperature exceeds
45.0°C, the backup system will immediately interrupt
power to the heaters. If the over-temperature
condition is a temporary occurrence as a result of a
sudden change in flow rate, the display will alternately
flash
HI
and the fluid temperature. When the fluid
temperature returns to acceptable temperature levels,
normal operation will resume. If, however, the backup
system detects that the over-temperature condition is
a result of a failure of the main controller, an audible
alarm will sound, the RFU (
REMOVE FROM USE)
indicator will light, and the device will shut down.
If this occurs, immediately stop the fluid flow, discard
the warming set, and contact your dealer for service.
4.2 Self-diagnostics
Each time the warming unit is switched from
STANDBY
mode to
RUN
mode, a self-test is initiated. If the
backup system is not functioning properly, an error
message will be displayed and the unit will shut down.
In addition, self-tests are routinely performed during
RUN
mode to ensure continued safe operation of the
warming unit.
4.3 Control Alarm
LO
If the warming unit senses a fluid temperature less than
34.0°C, the audible alarm will chime and the display
will alternately indicate the symbol
LO
, and the actual
fluid temperature.
Exception:
The unit will not alarm until the fluid
temperature has initially surpassed the
34.0°C threshold.
5.0 Cleaning
Do not immerse the warmer in cleaning or
disinfectant solutions. Do not submerge it in
liquids; it is fluid-resistant, not fluid-proof.
Immersion could result in malfunction
or equipment damage.
Perform the following care and cleaning between
patient use or per facility protocol.
•
Unplug unit prior to cleaning
•
To clean the external surfaces of the warmer, use
a non-abrasive cleaning solution (such as warm
soap water) and a clean cloth.
CAUTION
CAUTION
ENGLISH
•
Clean inside of cassette slot with disposable brush.
Carefully flush using squeeze bottle with water.
Replacement cleaning kit P/N 78350-000.
•
Apply a disinfectant such as 10% chlorinated
bleach solution (chlorinated bleach with 5.25%
sodium hypochlorite) to both the outside of the
unit and the cassette slot and allow to dry.
The warming unit should be cleaned if any
fluid or foreign substance has entered the
cassette slot.
Failure to keep the cassette
slot clean could impede cassette
insertion.
