Mattress will not inflate or every other cell is not inflating:
• Disconnect the control unit and make sure air is flowing from the open ports. This is done by
disconnecting the control unit from the mattress and physically feeling the air blowing out from
one port and then the other. It may take several minutes to switch from one port to the other
depending on the control unit's cycle time. If the control unit is not blowing air out of the ports,
call for service.
• Check to make sure the control unit is on.
• Check to make sure the control unit is properly connected to the mattress.
• Check to make sure the red CPR plug is closed.
• Open mattress and inspect the internal connections to make sure each individual air cell is
properly connected and not leaking. If a defect is discovered, call for repair or replacement of
defective component.
• Visually inspect each air cell to make sure there are no cuts, punctures, or tears in the material
with the exception of the low air loss holes designated by the white circles on the air cells. If a
defect is discovered, call for repair or replacement of defective component.
• Check to make sure there are no kinks or leaks in the internal and external hoses. If a defect is
discovered, call for repair or replacement of defective component.
Mattress is soft and will not increase pressure
or Low Pressure Alarm is sounding:
• Check control unit to make sure it is on and functioning properly. If the control unit is not
functioning, call for service.
• Inspect the air filter to make sure it is clean. The filter is located on the back of the control unit. The
filter should be white in color and free of dust or other debris. If the filter is not clean, replace with
a new filter.
• Visually inspect each air cell to make sure there are no cuts, punctures or tears in the material with
the exception of the low air loss holes designated by the white circles on the air cells. If a defect is
discovered call for repair or replacement of defective component.
NOTE: The pressure in the mattresses lowers when the weight of the resident is removed from the
mattress. The alarm will sound until the pump re-establishes the pressure level. In this situation wait
approximately 5 minutes and check it again.
Control unit is not working:
• Check to make sure the control unit is plugged into a live electrical socket.
• Make sure the control unit is turned on.
• Check the external fuses to make sure the fuses are in good condition. Make sure the control
unit is unplugged from the power source when checking fuses. Locate the fuses on the back
side of the control unit under the air filter cover. Unscrew the fuse cap and inspect the fuse to
see if the filament, small wire inside of the glass tube, is broken. If the filament is broken, install
new fuse and reinsert the fuse cap. Be sure the replacement fuse is of the same voltage and
amperage as the previous fuse.
