Using the Handheld Temperature Controller

After the hose has been connected to the Bair Hugger gown, the
patient can adjust the air temperature and airflow by turning the knob
on the handheld temperature controller. The following list explains
how the patient adjustable warming unit will operate when the knob
is placed in the specified position shown in the figure.
• When the knob is in position A, the patient adjustable warming
unit is off.
• As the knob is rotated from position A to B, the knob clicks and
the patient adjustable warming unit turns on low airflow and
low heat.
• As the knob rotates clockwise, the blower's airflow and
temperature increases.
• At position C, the patient adjustable warming unit is on HIGH
HEAT and HIGH AIRFLOW. The air temperature will stabilize at
43±3°C (109±5.4°F).

Using the Holder for the Handheld Temperature Controller

Store the handheld temperature controller in the controller holder to
help prevent cord clutter around the patient and accidental damage
to the patient adjustable warming unit.
Press the controller holder onto the patient adjustable warming unit
hose so it is within the patient's reach.
1. Slide the handheld temperature controller into the holder.
It should fit securely with the dial facing the patient.

What to Do if the "Over-temp" Indicator Light illuminates
and the Audible Alarm Sounds
Warning: Do not continue warming therapy if the red Over-temp
indicator light illuminates and the alarm sounds. Unplug the patient
adjustable warming unit and contact a qualified service technician.
If the "Over-temp" indicator light illuminates, it means that the patient
adjustable warming unit is delivering air at a higher temperature
than the patient adjustable warming unit is calibrated to deliver.
When an over-temperature condition occurs, the color indicator
light illuminates, an audible alarm will sound, and the heater will
automatically turn off (the blower will continue to run). You should
perform the following steps:
1. Discontinue patient warming.
• Turn the patient adjustable warming unit off.
• Disconnect the patient adjustable warming unit hose from
the Bair Hugger warming gown.
2. Unplug the patient adjustable warming unit from the power
source and wait 5 minutes.
3. Reconnect the patient adjustable warming unit to a proper
power source.
4. Turn the patient adjustable warming unit on and select the
maximum airflow and temperature setting by turning the
handheld temperature controller knob completely clockwise.
5. Allow the patient adjustable warming unit to run for at least 5
minutes.
• If the "Over-temp" light illuminates again, return the patient
adjustable warming unit to 3M Patient Warming for service.
• Otherwise, reconnect the patient adjustable warming unit
hose to the Bair Hugger gown to resume patient warming.

Cleaning, Storage and Maintenance

Calibrating the Operating Temperatures

Calibrate the operating temperatures of the Model 875 patient
adjustable warming unit (1) after performing a service procedure and
(2) routinely every six months. Perform the calibration in a similar
environment temperature to where the Model 875 will be used. You
will need a Bair Hugger temperature test kit Model 90055 to perform
the calibration. Calibration instructions are included with the test kit.

Replacing the Filter

Replace the filter every six months or sooner if necessary. To order a
replacement filter, contact 3M customer service using either of the
telephone numbers listed below. Instructions for replacing the filter
will be included with the replacement filter.
Caution: 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.
