INSTRUCTIONS FOR USE
The instructions below describe how to operate the Model
775 warming unit. For information about using 3M blankets, gowns,
or the 241 blood/fluid warming set with the Model 775 warming unit,
refer to the respective Instructions for Use.
1. If the Model 775 warming unit is not mounted on an IV pole or
Bair Hugger rolling stand, place the warming unit on a flat, hard,
dry surface, such as a table, before beginning warming therapy.
!
Caution: Do not place the warming unit on a soft uneven
surface, such as a bed, or a visibly wet surface as the air
intake may become blocked and cause the warming unit to
overheat, compromising the warming unit's performance.
2. Insert the end of the Bair Hugger warming unit hose in the
warming blanket or gown hose port. Use a twisting motion to
ensure a snug fit. A visual marker is located around the
mid-section of the hose end to guide the depth of hose
insertion. (Figures E). Support the hose to ensure
secure attachment.
!
Warning: Do not treat patients with the Bair Hugger
warming unit hose alone. Always attach the hose to a
Bair Hugger warming blanket/gown before providing
warming therapy.

3. Connect the warming unit to a properly grounded power
source. The warming unit will be in Standby mode and
the Standby indicator light will illuminate. The high fan
setting ( ) will be pre-selected by default with its indicator
light illuminated. The low fan setting ( ) may be pre-selected
prior to selecting the desired temperature mode.
4. Press the appropriate button (i.e., 32˚C, 38˚C, 43˚C, or
Ambient) to select the desired temperature. This will turn
the blower and heater ON. When the warming unit reaches
the selected temperature, the Temp in Range indicator light
will illuminate; this indicator light does not illuminate in the
Ambient mode.
!
Caution: Patient Monitoring Recommendations:
• 3M recommends continuously monitoring core
temperature. In the absence of continuous monitoring,
monitor the temperature of patients who are incapable
of reacting, communicating and/or who cannot sense
temperature a minimum of every 15 minutes or according to
institutional protocol.
• Monitor cutaneous responses of patients who are incapable
of reacting, communicating and/or who cannot sense
temperature a minimum of every 15 minutes or according to
institutional protocol.
• Adjust air temperature or discontinue therapy when the
therapeutic goal is reached, if elevated temperatures are
recorded or if there is an adverse cutaneous response in the
warmed area.

5. Press the Standby button when warming therapy is complete.
Disconnect the warming unit hose from the warming blanket/
gown and discard the blanket/gown per hospital policy.
6. Unplug the warming unit to disconnect it from the
power source.
Note: At any time, the fan speed setting can be switched between
high fan setting ( ) and low fan setting ( ) by pressing the
corresponding button. However, these buttons will not place the
warming unit into Standby.
Viewing the Temperature Mode Timer
The temperature mode timer records the amount of time the warming
unit has been operating in the selected temperature mode. The timer
resets itself every time you select a different temperature mode.
To view the temperature mode timer, press the button and hold for
3 seconds for the current temperature mode. The alphanumeric
display will show the temperature mode time, then go back to
showing the temperature mode setting.
What to Do in Case of an Over‑Temperature Condition
If an over-temperature condition occurs, the red Over‑temp indicator
light flashes and an audible alarm sounds and the warming unit
automatically turns OFF the heater, blower, and operating mode
indicator lights. A fault code appears in the alphanumeric display.
Note: Pressing any button will silence the alarm.
IF AN OVER‑TEMPERATURE CONDITION OCCURS:
!
Warning: Do not continue warming therapy if the red
Over-temp indicator light illuminates and the alarm
sounds. Unplug the warming unit and contact a qualified
service technician.
!
Warning: Do not continue 241 blood/fluid warming therapy
if the red Over-temp indicator light illuminates and the alarm
sounds. Immediately stop fluid flow, and discard the blood/fluid
warming set. Unplug the warming unit, and contact a qualified
service technician.
1. Discontinue all warming therapy. If you are using the 241 blood/
fluid warming set, immediately stop fluid flow and discard the
blood/fluid warming set.
2. Press any button on the control panel to silence the alarm.
3. Unplug the warming unit.
4. Replace warming unit. Do not attempt to restart or reset the
warming unit.
5. Contact a qualified service technician.
What to Do If a Fault Condition occurs
The Model 775 warming unit software recognizes several
non-hazardous conditions and reports those conditions as faults.
When a system fault occurs, the software stores the fault code
in memory, the amber Fault indicator light flashes, and an alarm
sounds. The warming unit automatically turns the heater, blower,
and operating mode indicator lights OFF. The control panel will not
respond to commands.
Note: Pressing any button will silence the alarm.
IF A FAULT CONDITION OCCURS:
1. Unplug the warming unit and wait for 30-60 seconds.
2. Reconnect the warming unit to a grounded power source. The
warming unit will perform the normal power-on-reset sequence
and then enter the Standby mode.
3. Reselect the temperature setting.
4. If the warming unit does not return to normal operation, contact
a qualified service technician.
