ROHO DRY FLOATATION Wheelchair Cushions Operation Manual
Important Safety Information
ROHO medical products are intended to be part of an overall care regimen. ROHO, Inc.
recommends that a clinician make product recommendations based upon an evaluation
of the individual’s medical and therapeutic needs and overall condition.
Warnings
• Skin/soft tissue breakdown can occur due to a number of factors, which vary by
individual. Check skin frequently, at least once a day. Redness, bruising, or darker
areas (when compared to normal skin) may indicate the beginning of soft tissue
breakdown and may need to be addressed. If there is any discoloration to skin/soft
tissue, STOP USE immediately. If the discoloration does not disappear within 30
minutes after disuse, immediately consult a healthcare professional.
• The cushion and the cover MUST be compatible sizes and MUST be used as directed
in this manual. IF THEY ARE NOT: 1) The benefits provided by the cushion may be
reduced or eliminated, increasing the risk to skin or to other soft tissue, and 2) the
individual may become unstable and vulnerable to falling.
• DO NOT use your cushion on top of, or in conjunction with, any other products or
materials, except as indicated in this manual. Doing so may cause the individual to
become unstable and vulnerable to falling.
• DO NOT use your cushion as a water flotation device (e.g., a Life Preserver). It will
NOT support you in water.
• If you are unable to perform any tasks described in this manual, seek assistance.
Cautions
• DO NOT use a pump, cover, or repair kit other than those provided by ROHO, Inc. Doing
so may void your product's warranty.
• DO NOT modify the cushion or any components. Doing so may result in damage to the
product and will void the warranty.
• DO NOT allow your cushion to come into contact with oil-based lotions or lanolin. They
may degrade the material.
• Prolonged exposure to ozone may degrade materials used in the cushion, affect the
performance of the cushion, and void the product warranty.
• Changes in altitude may require adjustment to your cushion.
• Keep your cushion away from sharp objects.
• DO NOT expose your cushion to high heat, open flames or hot ashes.
• If the cushion has been in temperatures lower than 32° F (0° C) and exhibits unusual
stiffness, allow the cushion to warm to room temperature.
• DO NOT use an inflation valve as a handle for carrying or pulling your DRY FLOATATION
cushioning device. Carry your cushioning device by the cushion base or by the carrying
handle on the cover.

Cushion Adjustment
1. Inflate the cushion:
a. Place the cushion in
the wheelchair with the
air cells facing up and
the non-skid surface of
the cover facing down.
Consult your prescriber
about alternate
positions of inflation
valves.
b. For SELECT Cushions: Before inflating, you must
open the ISOFLO Memory Control so that all of
the air cells will inflate. Push the ISOFLO green
knob toward the unlocked position.
c. Slide the rubber nozzle of the hand pump over
the inflation valve. Pinch the
nozzle, turn to open the inflation
valve, and inflate the air cells.
d. When all of the air cells are
inflated and the cushion begins
to arch slightly, pinch the rubber
nozzle of the hand pump and turn to close the inflation valve completely.
e. Remove the hand pump.
f. Repeat cushion inflation for all valves.
Important Safety Information:
• Check inflation frequently, at least once a day!
• DO NOT use an under-inflated cushion or an over-inflated cushion because the
product benefits will be reduced or eliminated, resulting in an increased risk
to skin and other soft tissue. If the cushion does not appear to be holding air,
or if you are not able to inflate or deflate the cushion, see TROUBLESHOOTING.
Immediately contact your clinical caregiver, distributor, or ROHO, Inc. if the
problem persists.
• When possible, use the hook or loop fasteners to further secure the cushion
to the seating surface.

2. Adjust the cushion:
a. The individual should sit in the chair in
their usual position. The cushion should
be centered beneath the individual.
b. Slide your hand between the cushion and
the individual. Lift the leg slightly and feel
for the lowest bony prominence, and then
lower the leg to a sitting position.
c. Open the valve to remove air,
keeping your hand beneath
the individual’s lowest bony
prominence.
d. Release air until you are barely
able to move your fingertips.
e. Close the valve.
f. Repeat cushion adjustment for all
valves.
g. To adjust the QUADTRO SELECT Cushion or the CONTOUR SELECT Cushion
to accommodate a fixed pelvic obliquity or a fixed posterior pelvic tilt:
The individual should sit in their normal position
while the air transfers through the ISOFLO Memory
Control. When the air transfer is complete, push
the red knob toward the locked position. Check
each compartment of the cushion to ensure a
Proper Cushion Inflation Setting.
Note: See the next page for instructions on adjusting the QUADTRO SELECT
Cushion to correct a flexible pelvic obliquity or a flexible posterior pelvic tilt.

h. To adjust the QUADTRO SELECT Cushion to correct a flexible pelvic
obliquity or a flexible posterior pelvic tilt:
- Follow all Cushion Adjustment instructions in this operation manual to make
sure the cushion is adjusted to a Proper Cushion
Inflation Setting.
- Make sure the ISOFLO Memory Control is in the
unlocked position
- Follow the instructions below.
Flexible pelvic obliquity:
1)Manually correct to the desired pelvic position. (For example, if the left
side of the pelvis is lower than the right side, either have the individual
lean toward the right, or place downward pressure on the right hip until
the desired position is achieved.)
2)Push the red knob toward the locked position.
3)Re-check each compartment of the cushion to
ensure a Proper Cushion Inflation Setting.
Flexible posterior pelvic tilt:
1) Check to make sure there is approximately 1" (2.5 cm) of space between
the individual's bony prominences and the seating surface. Add more air if
needed.
2) Lift both of the individual's knees to put more downward pressure on the
pelvis and to force air to the front of the cushion. This will create a "well"
(a lower, concave area) for the pelvis and will help prevent the pelvis from
sliding forward.
3) Push the red knob toward the locked position.
4) Re-check each compartment of the cushion to ensure a Proper Cushion
Inflation Setting.

Cover Removal and Replacement
Inspect the cover for damage and replace if necessary.
Keeping a cover on your cushion will help to protect the cushion components. A cover will also help to
keep the air cells together, which may aid in slide board transfers.
Cover Removal: Unzip and remove the cover from the cushion.
Cover Replacement:
1. Turn the cover and the cushion upside down: The non-skid
material should face up and the zipped opening should face
you. The air cells should face down.
2. Insert the cushion into the cover, following the instructions
below.
Standard Cover Instructions Heavy Duty Cover Instructions
The back of the cushion should face the zipper. The front of the cushion (the inflation valve)
should face the zipper.
Make sure all four corners of the cushion
extend through the corner openings in the
cover. Carefully pull the inflation valve and the
Yellow Rope through the openings.
Tuck the inflation valve and the Yellow Rope
inside the cover.
Close the zipper completely. Turn the cushion over so the air cells face up. The cushion should lie
flat inside the cover with the non-skid material on the bottom and all cells covered.
Troubleshooting
For additional assistance, contact your clinical caregiver, distributor, or ROHO, Inc.
Not Holding Air Inflate the cushion. Inspect the inflation valve(s) and hose(s) for
damage. Confirm that the inflation valve is completely closed. Look
for holes in the cushion. If very small holes or no holes are visible,
follow the instructions in the Repair Kit provided with your product.
For inflation valve or hose damage, or for large holes or leaks in the
cushion, see the ROHO Limited Warranty supplement, or contact
Customer Care.
Not Able To Inflate or
Deflate the Cushion
Confirm that the inflation valve is open. Inspect the inflation valve(s)
and hose(s) for damage. When inflating SELECT Cushions: Confirm that the
green knob of the ISOFLO Memory Control is pushed toward the center of the
ISOFLO in the UNLOCKED position so that all chambers will inflate.
Uncomfortable or
Unstable
Confirm that:
- the cushion is not over-inflated (See Cushion Adjustment.)
- the cushion cells and the top of the cover are facing up.
- the cushion is centered beneath the individual.
- the cushion is properly sized to the individual and the wheelchair.
Allow the individual at least one hour to adjust to the cushion.
The Cushion Slides on
the Wheelchair
Make sure the non-skid bottom of the cushion cover is facing away
from the individual. Use directional labels on the cushion and on the
cover to orient the cushion. Use hook and loop fasteners to further
secure the cushion to the wheelchair.
Refer to the label on the
bottom of the cushion and
to the image on the cover
to correctly orient your
cushion and cover.
