Precautions
Do not initiate patient warming unless the Model 850 warming unit is safely placed on a hard
surface or securely mounted. Otherwise, injury may result.
e Model 850 warming unit meets the international electronic interference requirements of EN
60601-1-2 and EN 55011. However, if radio frequency interference with monitoring equipment
occurs, connect the warming unit to a different power source.
Monitor the patient’s temperature every 10-20 minutes or according to institutional protocol
and monitor the patient’s vital signs regularly.
Proper Use and Maintenance
Arizant Healthcare Inc. assumes no responsibility for the reliability, performance, or safety of the

Wall-mount bracket
Preparing the Bair Paws Model 850 Warming Unit for Use
Before you begin using the warming unit, make sure that it is safely placed on a flat, hard surface
such as a table, or securely mounted on a wall, IV pole, or bedrail.
C: Do not place the warming unit on a soft or uneven surface, such as a bed, or the air intake
may become blocked.
A wall-mount bracket is shipped with every warming unit; the brackets for mounting the warming
unit to an IV pole or a bedrail are available separately. Please contact your local sales representative
or call Arizant Healthcare® customer service at 1-800-733-7775 for more information about ordering
mounting brackets.
e following instructions for mounting the warming unit assume that the brackets have already
been attached to the wall or to the warming unit.
Placing the Warming Unit on the Wall-mount Bracket
Slide the V-shaped bracket on the back of the warming unit into the groove of the
wall-mount bracket.
Lift the warming unit straight up to remove it from the wall-mount bracket.

Mounting the Warming Unit on an IV Pole
C: To prevent tipping, mount the Model 850 warming unit on an IV pole at a height that
ensures stability. We recommend mounting the warming unit no higher than 44 in. (112 cm) from
the floor on an IV pole with a minimum wheelbase radius of 14 in. (35.6 cm). Failure to do so may
result in IV pole tipping, leading to potential catheter site trauma and other patient injuries.
Position the IV pole-mount at the desired height on the IV pole.
Turn the clamp knob on the IV pole-mount clockwise to tighten the clamp to the pole.
Slide the V-shaped bracket on the back of the warming unit into the groove
of the IV pole-mount.
Mounting the Warming Unit on a Bedrail
Hang the Model 850 warming unit on a bedrail by the hooks on the rail-mount that has been
pre-attached by a biomedical technician to the back of the unit.
Wrap the safety strap around the bedrail and connect the end to the fastener on the strap.
The safety strap will prevent the warming unit from falling if the rail-mount is inadvertently
dislodged from the bedrail.

Using the Hand-held Temperature Controller Holder
e controller holder helps to prevent cord clutter around the patient and accidental damage
to the controller.
What to Do if the “Over-Temp” Indicator Light Illuminates
If the “Over-Temp” indicator light illuminates, the warming unit has detected warmer air than what
would be expected under normal operation. is event may occur if airflow through the system
becomes blocked or if the unit is improperly calibrated. When an over-temperature event occurs, the
heater and blower automatically turn off to ensure safety. You should perform the following steps:
Discontinue patient warming.
Disconnect the warming unit hose from the Bair Paws warming gown.
Turn the warming unit OFF.
Unplug the warming unit from the power source and wait 5 minutes.
Reconnect the warming unit to the grounded power source.
Turn the warming unit ON and select the temperature setting.
Allow the warming unit to run for at least 5 minutes.
If the “Over-Temp” light illuminates again, return the warming unit to Arizant Healthcare
for service.
Otherwise, reconnect the warming unit hose to the Bair Paws gown to resume patient
warming.
