PRODUCT DESCRIPTION
Span-America’s proprietary use of non-collapsible “Air Diffusion
Matrix” fabric in both the inner air-delivery cover and the outer
removable coverlet maintains an air pathway underneath the
user, thus transporting moisture vapor away from the user’s skin.
Both the inner air-delivery cover and the outer removable
coverlet are bacteriostatic, flame resistant and fluid proof. Since
they do not allow fluids to penetrate the surface to the mattress,
maintenance is minimal. The air-cylinder inflation system and the
foam shell work in concert to maintain low interface pressures
throughout the surface, making the Easy Air LR effective for
treatment of pressure injuries by preventing further tissue
breakdown.
Close-up illustrations of the outer removable coverlet and the
inner air-delivery cover, and an explanation of the science
behind the design are found on page 10.

ILLUSTRATION DESCRIPTIONS
1. Outer
Removable
Coverlet:
The outer coverlet is fluid proof, cleanable and flame resistant. It can
be replaced if damaged or worn. The coverlet is highly vapor permeable
(4500 grams/meter2/24 hours) and fluid-resistant. Both of its fabrics
(smooth top fabric and the crush-proof air diffusion matrix fabric) are
bacteriostatic. Coverlet can be routinely wiped clean and disinfected in
place, or can be removed and machine laundered according to
directions in this manual.
2. Inner
Air-Delivery
Cover
The gray, multi-layered cover serves as a barrier, protecting the inside of
the mattress from both fluids and vapors, while supplying air to the
microenvironment between the cover and coverlet. Unlike the purple
removable coverlet, it is intended to remain on the mattress at all times.
It can be cleaned and disinfected in place using standard hospital,
medical grade products. The air delivery cover is a gray urethane fabric
with a welded pattern and air holes designed to deliver air flow to the
top of the mattress to flow underneath the patient in the removal of
moisture from the patient’s skin.
3. Air
Cylinders
The inflation system consists of air cylinders that run lengthwise
underneath the body. Unlike typical low air loss systems, the cylinder
inflation system does not lose air from the inflation system for
microclimate management, and can be programmed to perform either
Flotation, Alternating Pressure or Lateral Rotation. The cycles and
inflation levels are designed to provide and maintain low interface
pressures throughout the mattress, and to redistribute peak interface
pressure points during all therapy modes.
4. Foam Shell
The foam topper is a high density, medical grade foam that provides
patient comfort, support, and pressure redistribution. The proprietary
Safety Edge™ consists of contoured foam bolsters around the perimeter
and ends of the mattress for added patient stability and positioning.
5. Control
Unit
The quiet, energy-efficient control unit houses both a high volume air
blower and a lower volume air compressor. The blower component
provides air for the microclimate management function through the
cover/coverlet, while the compressor component provides air to the
air-cylinder inflation system. The filter on the control unit should be
cleaned regularly.

10
THE SCIENCE BEHIND EASY AIR LR
MICROCLIMATE MANAGEMENT DESIGN
Easy Air’s exclusive “Air Diffusion Matrix” design maximizes
removal of excess moisture (i.e., perspiration) from the user’s
skin. Moisture passes in vapor form down through the cover,
where a continuous air current takes it away before it can re-form
as liquid.
The Air Diffusion Matrix fabric is not collapsible, ensuring a
pathway for a constant flow of air beneath the patient. Compare
to typical “low air loss” designs that cause the patient’s body to
press the cover directly onto the air holes, closing off the flow of
air beneath the patient.

MATTRESS AND CONTROL UNIT SET-UP DIRECTIONS
1. Place the mattress on a standard hospital bed frame with the
outer coverlet facing up, and the connector access at the
foot-end of the bed, to the patient's right. Note that the
connector access is on the inner gray top surface air delivery
cover, which should also be facing up, under the purple
coverlet.
2. Hang the air-control unit on the foot-end of the bed or place
on the floor as desired. Avoid blocking vent holes of filter on
the back of the control unit housing.
WARNING: Do not position equipment in such
a way that it will block the removal or addition
of the separable power cord from the device.
3. Plug the power cable into the connector module on the air-
control unit (on lower lefthand side when facing the control
unit) and plug the opposite end into the wall outlet.
Always plug the power cable securely into the
wall outlet. Make sure the wall-mounted
outlet will accommodate a heavy duty or
hospital-grade plug and that the outlet is in good working
order. The plug of the power cord should fit tightly into the
wall outlet. The plug body, the wall outlet, and the wall plate
should not be cracked or chipped. The plug blades should be
securely retained in the plug body. The ground pin of the
plug should be intact and secure.
Do not connect the power cord to an extension cord or to a
multiple outlet strip. If the use of extension cords or multiple
outlet strips cannot be avoided, use only heavy duty or
hospital-grade connectors that are approved by the facility
engineering department. Multiple outlet strips should be
mounted on a fixed object to reduce the risk of liquid spills
and physical damage. In addition, if multiple-receptacle
outlet boxes are used, they also should be protected from the
risk of liquid spills and physical damage. All extension cords
and multiple outlet strips should be tagged and inspected
routinely.

12
Do not cover the power cord with a rug or carpet. Rugs or
carpets can prevent normal air flow, which can lead to
greater heat built-up. Place the cord in a low or no traffic
area. Check to be sure the motion of the bed does not
interfere with the bed’s power cord or plug.
Do not position power cord over edge of bed frame or drape
loosely at the side. This may introduce possible strangulation
of the patient.
Never thread power cords through mechanical
parts of the bed or bed rails where normal bed
movement may damage or cut the cord.
Note: If the pump is quickly restarted after a power interruption,
you may encounter fluctuating power indicated by blinking lights.
Turn power off. Wait at least 5 seconds before restarting.
4. Connect the air lines extending from the mattress into place
on the side of control unit.
- Air Delivery Line: The large diameter air line delivers a high
volume air flow to the top layer of mattress. Click the male
fitting of the large diameter air line into place in the female
air outlet on the side of the control unit.
Attaching main air
delivery line
To disconnect, press gray
button on the outlet. This will
release and eject the air line.

13
P11544 R3 CO#2643
- Support Cylinder Air lines:
The small diameter air
lines deliver air flow to the
support cylinders inside
the mattress. Four fittings
are mounted into one
connection plate. Position
fittings and click
connectors into place on
appropriate location on
side of control unit. Verify
secure connection with
“click” for both metal
connectors.
- To disconnect: Use thumb and
forefinger to press concurrently
the two silver release buttons
located on the uppermost left and
lowermost right connectors. This
will release and eject the air line
connector plate.
!
Never thread air lines through mechanical parts of the
bed or bed rails where raising, lowering, or gatching of
the bed may damage the air lines or the control unit
itself. Check to be sure the routing of the air lines or the
motion of the bed does not impede air flow by crimping
the air lines.
