Problem
The air flow from the Solo
seems warm.
The Solo is making a faint
humming sound when the
air flow is turned off.
The noise level of the Solo
has changed to include
unusual or harsh sounds
during operation.
The Solo will not turn on.
The Solo Plus has hours
recorded on the time meter
when it is delivered.
Solutions
Replace or clean the filter. Make sure the Solo is away from bedding or
curtains that could block the flow of air around the Solo. Make sure the
Solo is away from heating equipment (e.g., forced air vents, radiators).
This is a normal characteristic of the Solo. If the humming sound
is significantly louder than it usually is, contact your home care
provider or Respironics, Inc. for directions on having the Solo
serviced. Please have the Solo’s serial number ready when you call.

Make sure that the Solo is plugged into a working outlet. Replace the
Solo’s fuses if the green signal light does not come on. Verify that the
correct voltage has been selected (i.e., if your electrical line is 115 V you
must use the 115 V voltage setting). Press the Pressure On/Off button. If
the new fuses blow out, contact your home care provider. If you are
using a DC battery, the battery may need to be recharged or replaced.
The Solo Plus is tested at the factory prior to shipment. It is normal
for up to 200 hours of testing time to be recorded on the Solo Plus.
