System installation
The following describes the procedures for setting
up the system for the rst time.
a) Remove all covers, sheets and mattress from
the bed.
b)On a standard bed, position Mattress
Replacement on top of bed, printed top cover
facing upwards and air hoses towards the base
of the bed. Attach to the bed by securing the
adjustable straps under each end of your bed.
Ensure buckles are securely fastened and straps
are pulled tight.
c) IMPORTANT: On a proling bed, secure the
side straps around the moveable sections of the
bed base. DO NOT secure to the side rails or
main bed frame – irreparable damage could be
caused to the bed and mattress
d) Conrm there are no sharp objects in the
immediate area which may risk damage to the
Mattress Replacement.
Pump Unit Activation
a) Position Control Unit by hanging hooks over
foot board of the bed or place unit on the oor
under the bed.
b) Attach the air hoses through the use of the
quick connector to the Control Unit. Ensure air
hoses do not kink between mattress, bed frame
and Pump Unit.
c) Plug the power cord into an electrical outlet
with grounded AC power.
NOTE: Before inserting the plug into the outlet,
make sure the voltage is compatible. Also make
sure this product is well grounded.
d) Switch the power button on. Allow up to 40
minutes for full ination.
e) The 8 pressure indicate lights will ash until
the mattress is inated and ready for patient
use. Once ready, the weight setting will show
a constant light at the 40kg weight setting.
Perform a “bottom out” test to ensure that
patient is properly suspended. Slide your hand
under the top cover along a deated cell in
the sacral (bottom) area. Secure sheets loosely
enough to ensure they do not interfere with cell
alternation.
Operation
NOTE: Always read the operating instructions
before use.
General
This product is designed to provide
maximum comfort to patients. Make sure that you
operate this product in a proper way optimizing its
value. Here we provide some general information
that you should be
aware of.
For products:
• DO NOT use another pump with different
specications unless instructed to do so by
OSKA Care
• DO NOT change any component by yourself.
If there is need for replacement or repair,
always contact OSKA Care
For patients:
When the pressure has been adjusted to a desired
level of rmness, the patient can then lie on the
mattress.
A rm surface will make it easier for the patient to
transfer or reposition. Make use of the static mode
function for this feature. To sit a patient up in bed,
press the Seat Button to increase the pressure to
have better support on sacrum area.
Hand check:
Check if the pressure is properly adjusted by
sliding one hand between the air mattress and bed
frame to feel the patient’s buttock.
Users should be able to feel the space in between,
and the acceptable range is approximately 25 to
40 mm (1” to 1-1/2”).

NOTE: Please follow instructions below for
detailed operating procedure of each type.
Step 1 Turn on the power. A beep sound will
begin the operation.
Step 2 The pump will enter into static mode
when the power is initially turned on.
First it will inate the mattress to 10-
15mmHg and then enter alternate mode.
If 10-15mmHg can not be reached within
30 minutes, the unit will stay in static
mode and keep inating. If 10-15mmHg
still can not be reached within 40 minutes,
the alarm will beep and its LED will come
on.
Press the Alarm Mute button to mute
the alarm.The alarm LED will continue
ashing.
Press the Alarm Mute button again to
re-enable the audible alarm.
Step 3 The alternating cycle time and pressure
level are set at 10 minutes and 30mmHg
initially. Select from the touch panel to
adjust the cycle time and pressure level to
the patients specic requirements.
NOTE: Press the static mode button from
the touch panel to provide a rm surface
that makes it easier for the patient to
transfer or reposition.The static mode
can support the patient by keeping the
mattress from bottoming out when the
patient is in a sitting position.The static
mode will revert back to alternating
mode after 20 mins.
Step 4 During normal operation, the unit will
monitor pressure. If the mattress pressure
is lower than the set pressure, the pump
will automatically inate the mattress to
the set level and then stop.The alarm will
beep and its LED will come on to alert a
low pressure condition.
Press the Alarm Mute button to mute
the alarm.The alarm LED will continue
ashing.
Press the Alarm Mute button again to
re-enable the audible alarm.
Step 5 Press the Max Firm button to
automatically inate the mattress to the
maximum level (65mmHg) for about 20
minutes.The pressure will return to a
previously set level after 20 minutes.
In case there is a bad connection of
tubing or any air leakage from the
mattress, this will result in a low pressure
condition, and it will activate the alarm
within 1 min.
NOTE: For suitable pressure, please refer
to page 8 for the hand check procedure.
CPR function
When there is an emergency requirement to
perform CPR on the patient, press the CPR button
at the head section of the mattress and disconnect
the air hose from the pump to release the air
quickly from the mattress.
Pressure set up
Users can adjust the pressure level of the air
mattress to a desired rmness by themselves or
according to the suggestion from a health care
professional.
NOTE: It is recommended to press Max Firm on
the panel when the mattress is rst inated. Users
can then easily adjust the air mattress to a desired
rmness according to the patient’s weight and
comfort.
Low pressure warning
When abnormal pressure occurs, the Low
Pressure indicator will come on. For some types
of pumps, the alarm will be activated to alert of a
low pressure condition. Check if the connections
are secure and correctly installed according to the
relevant instructions.
NOTE: If the pressure is consistently low, open
the zipper and conrm that all of the hoses are
properly connected.Then check for any noticeable
leakage in any of the tubes. If necessary, contact
