Mounting the Warming Unit to an IV Pole
To prevent tipping, clamp the Model 775 warming unit to an IV pole
at a height that provides stability. Clamp the warming unit no higher
than 44
"
(112 cm) from the floor on an IV pole with a minimum 28
"
(71 cm) diameter wheelbase.
Caution:
If mounted on an IV pole, the distance from the bottom of
the warming unit to the floor must be less than 44
"
(112 cm) and the
IV pole wheelbase diameter must be at least 28
"
(71 cm) to prevent
tipping.
METHOD
To mount the Model 775 warming unit to an IV pole, simply
turn the clamp handle clockwise to tighten the clamp on
the IV pole and counterclockwise to release it. Ensure
the IV pole bumper rests against the pole. See Figure D.

Instructions for Use
The instructions below describe how to operate the Model 775
warming unit. For information about using 3M blankets, and/or
gowns 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 cart 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.
