MAINTENANCE
NOTE: Power should be disconnected before beginning preventive maintenance on the
concentrator. The concentrator is 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.

Clean the cabinet with a mild household cleaner and non-abrasive cloth or sponge at
least one time a month. Do Not drop any liquid into the seam of the device.
