Invacare Corporation Oxygen Concentrator IRC5LX

DANGER: To prevent electrical shock, ALWAYS disconnect concentrator from electrical outlet before servicing.

NOTE: The Platinum Concentrators are specifically designed to minimize routine preventive maintenance at intervals of once per year. In places with high dust or soot levels, maintenance may need to be performed more often. The following MUST be performed at a minimum of one year in service to assure years of additional reliability. Refer to Troubleshooting on page 17 for plugged filter symptoms.

Only qualified technicians should perform preventive maintenance on the concentrator. Power should be disconnected before beginning preventive maintenance on the Invacare concentrator.
