LOW PRESSURE (LP)
In the event of hose disconnection or other problem that causes major air leakage, the Micro-controller will activate an
audio/visual signal to alert the caregiver by flashing “LOW PRESSURE” on the digital display (K-3 Elite and K-4 Elite
models) or flashing the amber “LOW PRESSURE” LED (K-3oem and K-4oem models) and turning on the buzzer. Once the
low-pressure problem is fixed, the audio/visual signal will cease and the unit will resume its operating set mode.
BOLSTERED MATTRESS (RSB)
& EVEN BOLSTERED MATTRESS (ESB)
The left and the right bolsters can be manually deflated by disconnecting the bolster deflate connector which is at the
bottom right corner (patient’s right) of the mattress.
PLEASE NOTE: Before using the mattress please make sure that the bolster deflate connector is
re-connected back into the bolster deflate valve.
BOTTOM SAFETY AIR PAD (OPTIONAL)
The bottom safety air pad can be manually deflated by disconnecting the air pad deflate connector which is at the bottom
right corner (patient’s right) of the mattress.
PLEASE NOTE: Before using the mattress please make sure that the air pad deflate connector is re-connected back
into the air pad deflate valve.
FOAM AIRE MATTRESS AS A NON-POWERED MATTRESS
Foam Aire mattress can be used as a non-powered mattress without the control unit. Before using the mattress connect the
control unit to the mattress and inflate the mattress by setting the control unit comfort level to 5 (K-3oem, K-4oem) setting of
22mmHg (K-3, K-4). Once the control unit fills the mattress and the pressure stabilizes then turn the unit off and disconnect
the hose assembly from the unit and store the control unit and the hose assembly in a storage area.
FOAM AIRE MATTRESS AS A POWERED MATTRESS
If need arises the Foam Aire mattress can be converted into a powered mattress by simply connecting the control unit to the
mattress using the hose assembly provided with the system. For operating instructions in powered mode please refer to
OPERATING INSTRUCTIONS ABOVE
