- Select the appropriate oxygen diluter (green for 24%, 26%,28% or 30%: white for 35%,40% or 50%).
- Slip the diluter onto the VENTURI barrel.
- Select the prescribed oxygen concentration by setting the indicator on the diluter to the appropriate percentage on the barrel.
- Firmly slide the locking ring into position over the diluter.
- If humidification is desired, use the high humidity adaptor. To install, match the grooves on the adaptor with the flanges on the diluter and slide firmly into place. Connect the adaptor to the humidity source with large bore tubing (not supplied).
- Warning: Use only room air with the high humidity adaptor. Use of oxygen will affect the desired concentration.
- Connect supply tubing to the diluter and to the appropriate oxygen source.
- Adjust the oxygen flow to the appropriate level(see table below) and check for gas flow through the device.
