Solution
Check that the power cord is connected to the power
socket.
Check the fuses.
When the mattress is inflated, the 3 static head cells are
filled last.
Check that the air tubes are connected to the pump.
Check that the CPR valves are closed.
Open the mattress and look for any leakage.
Comfort knob may be set up. Adjust the pressure slightly
and wait a few minutes.
Check that the CPR valve is closed.
Check for leaks from air cells or tubes.
Check again with the "hand check", see section 4.4.
Check that the air mattress is secured to the underlying
mattress with the elastic straps. If the mattress has a built‐
in foam pad, fasten it to the bed frame with the straps.
This is normal since the air flow alternates between every
other cell for a set cycle time (one cycle = 10 minutes).
Check how the pump is hung on the bed. Resonance can
occur in parts of the bed. Remove the pump and listen to
see whether this makes a difference. Can be remedied by
putting the pump on a flat, steady surface or by placing a
towel between the pump and bed.
