Mattress will not inflate or if 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 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 get 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.
• Inspect the air filter to make sure it is clean. The filter is located on the back of the
control unit near the upper left corner. 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 about 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.
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, 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.
