Troubleshooting Guide
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 release valve 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 your Direct Supply
account manager for repair or replacement parts.
• 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 Rather Than Firm, 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.
• 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 mattress 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 about five 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. Locate the fuses on the side of the
control unit near the on/off switch. Unscrew the fuse cap and inspect the fuse to see if
the filament, the 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.
