Do not use liquid directly on the FreeStyle or FreeStyle 5 unit to clean it. A list of
undesirable chemical agents includes but is not limited to the following,
according to the plastics manufacturer: alcohol and alcohol-based products,
concentrated chlorine-based products (ethylene chloride), and oil-based
products (Pine-Sol, Lestoil). These are NOT to be used to clean the plastic
housing on the FreeStyle or FreeStyle 5, they can damage the units' plastic.
Clean or replace the air intake / gross particle filter with warm soapy water between each
patients use. The patients should be instructed to clean this filter at least once per week,
depending on the environment, during normal operation.
Allow the unit to air dry. Then re-test oxygen concentration, test the duration of the battery
pack, and ensure the AC and DC power supplies are in good working condition before you
return the unit to your inventory.
Make the bleach solution a 1:100 dilution of 5.25% sodium hypochlorite. Mix one
part household bleach (e.g., Clorox with 99 parts cold tap water). To measure the
solution easily, take 1/4 cup of household bleach, and mix it with a gallon of cold
tap water. Allow the mixture to sit on potentially contaminated surfaces for ten
minutes.
CAIRE does not recommend the sterilization of this equipment.
