ENGLISH

•All air must be removed from the fluid lines
prior to connecting to the patient.
•Monitor the fluid lines to ensure they are air
free. Never administer fluids if there are air
bubbles in the line between the bubble trap
and the patient connector.
Failure to do so could result in the
introduction of air to the patient,
resulting in death or serious injury.
When fully inserted, the clear guide rail
should protrude no more than 0.5 cm from
the front of the warming unit. Failure to
fully insert the cassette may result in
damage to the cassette.
Close warming set input clamp. Remove the
protector from the female luer of the warming set
and connect it to the male luer on the IV
administration set. Remove the protector from
the male luer of the warming set. To minimize
temperature drop and priming volume, remove
unnecessary lead extensions at this time.
Invert the bubble trap.
Open warming set input clamp. Allow fluid to
prime the set. When the bubble trap fills to
approximately (2/3) full, close the output clamp.
Re-invert the bubble trap and place it into the
bubble trap receiver on the side of the warming
unit.
The bubble trap must be mounted and kept in
a vertical position at all times. Failure to do
so could result in the introduction of air
to the patient, resulting in death or
serious injury.
Press the RUN/STANDBY switch on the
front of the unit.
Upon successful completion of self-diagnostics,
the display will flash the setpoint for approximately
3 seconds, then begin warming the fluid to the
selected temperature.
The setpoint most recently used is retained
in memory, even after power is removed.
To select an alternate setpoint, first press the
SETPOINT switch momentarily.
This will cause the setpoint to be displayed and
flash for approximately 3 seconds. While the
display is flashing the setpoint, the user may select
any setpoint between 38.0°C and 43.0°C in 1.0°C
increments by repeatedly pressing the SETPOINT
switch.
NOTE: holding down the SETPOINT switch
indefinitely will not increment the setpoint.
After the selection has been made, the display will
continue to flash this setpoint for approximately
3 seconds, then revert to displaying the actual fluid
temperature. The setpoint can be checked at any
time during the procedure by momentarily
pressing the SETPOINT switch.
If required, connect an extension for patient
connection.
Purge air from remaining length of tubing by
opening output clamp and allowing fluid to flow.
WARNING

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.

oLabels, if peeling or missing
oScrews in cover
oBubble trap receiver
oPower cord
oIV pole clamp
6.2 Output Fluid Temperature
Verification
The FW600 Series Blood/Fluid Warmer is factory
calibrated at a flow rate of 100 ml/min with a set point
of 43.0°C.
To verify the output fluid temperature is correct:
1. The ambient room temperature must be between
20°C to 24°C.
2. Connect the test setup (see figure 7). Attach the
Gaymar FWT1 temperature sensor to the output
of the bubble trap.
Alternate method: Put a hole in the top of the
bubble trap and insert a temperature
measurement device through this hole. Make
certain sensor is completely submerged in
fluid then seal the hole in the bubble trap.
3. Connect the FWT2 flowmeter or flow
measurement/control device to the output of the
FWT1 temperature sensor.
Alternate method: If using the sensor in the bubble
trap method, connect the FWT2 flowmeter or
flow measurement/control device directly to the
output of the bubble trap.
4. Flow room temperature water through the
warmer at 100 ml/min (cc/min). Verify that the
bubble trap is maintained 1/2 to 2/3 full.
5. Turn the warmer on. Adjust the SETPOINT to
43.0°C. Allow it to run for 10 minutes.
6. Verify that the output water temperature is
43.0°C ± 1.1°C. If using the FWT1 temperature
sensor and an ohmmeter, verify that the resistance
is within 1019—1112 ohms.
If temperature or resistance values are not
met, check setup and repeat test. If still not
within range, contact your dealer for service.
This device is factory calibrated and cannot be
field adjusted.
6.3 Overtemp Protection Verification
Proper operation of the overtemp protection system is
verified each time the unit is switched from STANDBY
to RUN mode. Therefore, periodic testing of this
system is not necessary. However, the following
procedure may be used to force an OVERTEMP
condition in order to observe that the overtemp
protection system works:
ENGLISH

9
1. Insert any D25000 series Warming cassette
into the warming unit. Using hot tap water
(46°C–50°C), flow hot water through the
cassette for approximately 1-3 minutes.
2. Connect AC power to the warming unit. The
device should immediately sound the audible alarm
and light the RFU light.
6.4 Ground Resistance Check
Use a current leakage/ground resistance tester to
measure the resistance between the ground pin on the
power plug and the mounting screw on the IV pole
clamp.
The resistance value should not exceed 0.50 ohms.
Figure 7—Test setup
6.5 Current Leakage Test
Measure the maximum earth leakage current (ground
open). Measure all combinations of line polarity with
neutral open and closed. Values should not exceed the
following;
FW600 neutral closed ...... 150µA
FW600 neutral open......... 200µA
FW603 neutral closed ...... 250µA
FW603 neutral open......... 300µA
