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.

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.1.
Turn the clamp knob on the IV pole-mount clockwise to tighten the clamp to the pole.2.
Slide the V-shaped bracket on the back of the warming unit into the groove3.
of the IV pole-mount.
Mounting the Warming Unit on a Bedrail

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.2.
The safety strap will prevent the warming unit from falling if the rail-mount is inadvertently
dislodged from the bedrail.
