mini used portable oxygen concentrators for sale

1.Maintenance
1). The housing of the appliance is smooth and glossy and should be prevented from scratches by sharp edges.
2). For cleaning of the appliance, soft cloth damped with water can be used. Never use corrosive or organic solvent. Otherwise the cleaned surface will lose luster. 3. When the generating unit finishes the operating, disconnect the power supply promptly.
4). Do not modify the appliance to avoid influencing the outlet and inlet of the air and resulting in negative effect to the appliance performance.
5). Only authorized technician can handle the interior piping system.
6). If the appliance does not work properly, check the appliance under the guide of Trouble Shooting. If the trouble shooting does not work, contact the local retailer for technical resistance. If the appliance is beyond warranty coverage, cost fee will be charged for replacement parts and materials.
7). Water build up in the capsule should be immediately.
8). The filter of the generating unit should be cleaned regularly, usually once every 3 months. Remove the filter, then clean the filter with detergent and rinse the filter with clean water finally dry it and reinstall it.
