Use only the 3M-supplied power cord intended for this product
and certified for the country of use�
•
Do not allow the power cord to get wet�
•
Do not use the warming unit when it appears the warming
unit, power cord or any component is damaged� Contact 3M
Technical Support�
•
Do not disassemble the temperature management unit unless you
are a qualified service technician� There are electrically live parts
within the unit when it is connected to a power source�
•

•
Do not attempt to replace the filter while the warming unit is
in use�
CAUTIONS
CAUTION: To reduce the risk of cross-contamination:
•
Except for specific Bair Hugger warming blanket models, 3M
warming blankets/gowns are not sterile� Each warming blanket/
gown is intended for single patient use ONLY� Placing a sheet
between the warming blanket/gown and the patient does not
prevent contamination of the product�
•
Follow applicable regulations when disposing of this warming unit
or any of its electrical components�
•
Clean the warming unit and the outside of the warming unit
hose after each patient use� See "Cleaning Instructions" in the
Cleaning Instructions section� Do not attempt to clean the air
filter as it may be contaminated from use� Discard the filter in a
manner consistent with institutional protocol
•
Do not operate the Bair Hugger warming unit with the hose
detached from the 3M warming blanket/gown� The Bair
Hugger warming unit is intended to be used with the hose
properly attached to its corresponding warming blanket/gown
and in accordance with good practices for operating room
sterile technique�
CAUTION: To reduce the risk of fire:
•
3M warming blankets and gowns are classified as Class I Normal
Flammability as defined by the Consumer Product Safety
Commissions flammable fabric regulation, 16 CFR 1610� Follow
standard safety protocols when using high intensity heat sources�
CAUTION: To reduce the risk of patient or caregiver injury:
•
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�
•
Do not place the warming unit and rolling cart on an inclined
surface of more than 7 degrees with rear casters facing
downward angle�
•
Do not attempt to move the rolling cart when the front casters
are locked�
CAUTION: To reduce the risk of thermal injury, hyperthermia
or hypothermia:
•
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�

•
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�
•
Perform all temperature testing of the warming unit with a 3M
Model 22110 temperature test unit� The Model 22110 temperature
test unit itself requires no calibration�
•
Only use 3M-supplied power cord with the warming unit�
CAUTION: To reduce the risk associated with electromagnetic
interference (EMI) due to portable and mobile radio frequency (RF)
communications equipment:
•
The 3M Bair Hugger temperature management system has
been tested to be resistant to both EMI and electrostatic
discharge (ESD)�
•
Install and put into service the 3M Bair Hugger temperature
management system according to the electromagnetic
compatibility (EMC) information provided in the Guidance and
Manufacturer's Declaration�
•
Should interference occur, move away from the portable or
mobile RF communications equipment�
Notices
1�
The Bair Hugger warming unit meets medical electronic
interference requirements� If radio frequency interference with
other equipment should occur, connect the warming unit to a
different power source�
2� To avoid warming unit damage:
•
Use proper Electrostatic Discharge (ESD) procedures when
performing maintenance�
•
Do not modify this equipment without authorization from
the manufacturer�
•
Do not immerse the warming unit, warming unit parts
or accessories in any liquid or subject them to any
sterilization process�
•
Do not use cleaning solutions with greater than 80% alcohol
or solvents, including acetone and thinner, to clean the
warming unit or hose� Solvents may damage the labels and
other plastic parts�
