1.0 SAFETY PRECAUTIONS –
CAUTION! The BEDSIDE AIR CHAIR system is contraindicated for use with
certain medical conditions and treatments. Always consult with the patient’s
physician before placing a patient on an alternating pressure system.
CAUTION! Chair frames used with the BEDSIDE AIR CHAIR system can vary
greatly depending on the specific health care setting, e.g., hospitals, nursing
homes, home care, etc. Therefore, it is the responsibility of the caregiver to take
the necessary precautions to ensure the safety of the patient and to prevent falls
and/or patient entrapment.
Electronic Controller:
DANGER!
•Do not use in the presence of flammable anesthetics. Risk of explosion can
result.
•Exposure of the electronic controller to any liquid while it is plugged in could
result in a severe electrical hazard.
•Only use fuses that have the same specified rating (See Section 7.0
Product Specifications). Using fuses with higher ratings could result in
damage and/or injury.
CAUTION!
•Risk of Electric Shock. Do not open or attempt to repair or service the
electronic controller. Repairs and service should only be done by Tridien
Medical. If the controller is not functioning properly, or has been damaged,
unplug the unit and take it out of service immediately. Contact Customer
Service at 800-474-4225 or 954-340-0500 for repair and service information.
•The electronic controller is a precision electronic product. Use care when
handling or transporting. Dropping, or other sudden impacts, may result in
damage to the controller.
IMPORTANT!
•Do not return a product for any reason without first contacting Customer
Service to obtain authorization (See Section 9.0).
•Do not place any objects/items, such as blankets, on, or over, the electronic
controller. Excessive weight on the BEDSIDE AIR CHAIR controller could
result in damage.
•After exposure to extreme high or low temperatures, allow electronic
controller to equilibrate to room temperature before operating.

Page 5
1.0 SAFETY PRECAUTIONS (Continued) -
•The BEDSIDE AIR CHAIR system circulates room air during operation.
Exposure to smoke may cause the system to fail. Therefore, smoking by
patients, or visitors, while using the BEDSIDE AIR CHAIR system is strongly
discouraged.
•The power cord to the electronic controller should be positioned to avoid a
tripping hazard and/or damage to the cord. Tridien recommends placing the
cord under the chair and attaching it to an electrical outlet behind the chair.

2.0 PRODUCT OVERVIEW -
The BEDSIDE AIR CHAIR is a patented Alternating Pressure Overlay that
provides therapeutic pressure relief for patients sitting in a chair.
Alternating Pressure provides pressure relief by sequentially deflating and inflating
alternate air cells on a timed interval. It is widely recognized that constant pressure
to a bony prominence is the leading cause of skin breakdown. The continuous
movement provided by the BEDSIDE AIR CHAIR system alleviates these areas of
constant pressure and enhances circulation.
The deflated air cells provide pressure relief, while the inflated air cells support the
patient’s weight. The amount of pressure to support a patient can be adjusted,
based on the patient’s weight.
The chair overlay can also be used with the following Tridien controllers:
•Sentry 1200
•Stage IV 2000
•Stage IV 3000

Page 12
5.2.1 Washing and Disinfecting (Continued)
NOTE! 2.5 ounces of bleach per 10 gallons of water is approximately
100ppm of available chlorine.
CAUTION! Heat will severely damage the coverlet. DO NOT dry the coverlet
using the “heat” cycle. Air dry, or use a “non-heat” dry cycle, e.g., air fluff.
5.2.2 Washing Alternative
If there are no
1. Apply chlorine bleach, or an intermediate level disinfectant
visible signs of body fluids and/or substances present,
the coverlet can be sanitized between patients. To sanitize the
coverlet: at the
appropriate dilution
2. Ensure surface is completely covered with the bleach/disinfectant.
(See Section 5.2.1) to the upper surface of the
coverlet. Bleach/disinfectant may be applied either by spraying or

6.0 TROUBLESHOOTING GUIDE -
Problem
Cause
Solution
1. Low Pressure Alarm is on.
The alarm is triggered
when a cell(s) fails to
reach its programmed
pressure after an
extended period of time
(~20min.) This is usually
an indication of an air
leak somewhere in the
system.
a) Be sure all hoses are properly
connected to the controller.
b) Check all hoses along the inside
of the cushion. Each hose should
be tightly connected.
c) Check each air cell to ensure
there are no leaks.
d) After the leak has been
eliminated, reset the system by
turning the controller off and then
on.
2. Patient is sinking or
bottoming out and the
alarm light is not on.
Although some sinking is
normal for an air
cushion, the pressure
may be set too low for
the patient’s weight
distribution.
Increase weight setting using the
slide bar on the control panel until
patient is no longer bottoming out.
Wait at least one full cycle before
determining if the pressure increase
is adequate.
3. Controller does not work.
a) May be caused by a
power surge
substantial enough to
overload the internal
circuitry.
b) May be caused by
internal damage.
