MN220-‐1 A 47
Portable Oxygen Concentrator
EQUIPMENT PROVIDER MAINTENANCE
NO SCHEDULED MAINTENANCE
FreeStyle and FreeStyle 5 units are maintenance-‐free due to their technologically advanced
design. CAIRE does not require preventative maintenance or service on these concentrators as
long as the concentrator remains within specifications. To ensure that the unit’s output of
oxygen is within specification, you must establish and implement a protocol to check oxygen
concentration upon delivery to a patient and at periodic intervals (Reference OXYGEN
CONCENTRATION TEST section of this manual).
AIR INTAKE / GROSS PARTICLE FILTER
The external air intake gross particle filter is located in the air intake/filter cover. You can easily
remove it by hand. Instruct the patient to clean this filter weekly. (Reference CLEANING THE AIR
INTAKE / GROSS PARTICLE FILTER section of this manual).
The filter may require more frequent cleaning if the unit operates in a harsh
environment – a house heated by wood, kerosene, or oil, or one with excessive
cooking or cigarette smoke.
Turn OFF the unit and disconnect the power cord from the electrical
outlet before you clean the unit to prevent accidental electrical shock
and burn hazard.
Remove the battery from the unit before performing any maintenance to
prevent accidental electrical shock and burn hazard.
The FreeStyle or FreeStyle 5 must be off and disconnected from external power
before removing the battery pack.
PRODUCT FILTER REPLACEMENT
The product filter is designed to last the life of the unit. If it is determined that the product filter
needs to be replaced, follow the instructions below:
