What should I know about changes in refrigerants? Why should I choose an ENERGY STAR® product for my home?"Battery Empty, Attach Plug" - Why does the message remain after I attach the AC power supply? If the concentrator is run until the battery is depleted, the system is shut down (oxygen production is stopped) and this message is displayed. Even if the user connects the power plug at this time, further action is required. In order to cease display of the message, the user should press the ON/OFF button to shut the unit down completely. The user should then press the ON/OFF button to restart the concentrator. "Battery Error, See Manual" - Why do I get this message, and what should I do next? This message is displayed if the concentrator has difficulty communicating with the battery. The user should remove the battery and reinstall it (first shut the unit down or power it using the AC power supply). If this error regularly occurs, please contact OxygenToGo Customer Care for further instruction.

A battery error will prevent the battery from powering the concentrator. "Battery HOT Warning" - Why do I get this message, and what should I do next? The concentrator will shut down if the battery temperature is too hot. If the battery is just below this temperature, the user will receive the Battery HOT Warning on the display, along with an audible warning. This warning is simply intended to alert the patient that continued use of the battery may result in system shutdown if the battery temperature continues to increase. Note that the temperature of the concentrator and battery will be higher when used at higher flow settings. Suggestions for reducing the battery temperature are provided in the Patient Manual. If the battery regularly becomes too hot, please contact OxygenToGo Customer Care for further instruction. "Battery HOT, Not Charging" - Why do I get this message, and what should I do next? In order to begin charging, the battery must be below a certain temperature.

If the battery has recently been discharged in a concentrator, depending on environmental conditions, it may exceed this temperature and must cool down prior to charging. To expedite cooling, the user may run the unit on AC power, remove the battery for 10 minutes, or replace the battery with a cool battery, if desired. If the battery is left in the concentrator, the alert will continue to appear until the battery cools sufficiently to begin the charging sequence. "Comm Error" - Why do I get this message, and what should I do next?The battery will continue to power the concentrator if it is the sole source of power, but the concentrator will not be able to track the remaining charge on the battery. If AC power is used, the battery will not charge with a comm error showing. "Error 1, Call Provider" - Why do I get this message, and what should I do next? This error may result from an error in communication between the battery and the concentrator. Remove the battery and reinsert in the concentrator.

If the error regularly occurs, please contact OxygenToGo Customer Care for further instruction. "Error 16, Call Provider" - Why do I get this message, and what should I do next? If this error repeats itself to the point of becoming a nuisance, please contact OxygenToGo Customer Care for further instruction. "Error 4, Call Provider" - Why do I get this message, and what should I do next? This message indicates that the concentrator has detected pressure that is lower or higher than expected. When this happens, the concentrator is shut down. An Error 4 message is usually due to a low pressure condition. This may be caused by placing the concentrator in the Satellite setting without connecting a Satellite Conserver, or by having a leak in the tubing to the Satellite Conserver. This situation will allow the product gas to leak from the system, thereby reducing the internal pressure. If the user is sure that such a leak did not occur, then there may be a problem with the concentrator and it may need to be returned for troubleshooting.

Please contact OxygenToGo Customer Care for further instruction. Note: the error 4 message will not display until the concentrator has been operating for at least five minutes. "Error 8, Call Provider" - Why do I get this message, and what should I do next? This message indicates that the concentrator software has detected oxygen concentration below 50%. When this happens, the concentrator shuts down. An oxygen concentration this low may be caused by placing the concentrator in the “Satellite” setting without connecting a Satellite Conserver, or by having a leak in the tubing, allowing the product gas to leak from the system, thereby reducing the oxygen concentration. If the user is certain that such a leak did not occur, there may be a problem with the concentrator and it may need to be returned for troubleshooting. Please contact OxygenToGo Customer Care for further instruction. "System HOT, Shutdown" - Why do I get this message, and what should I do next? If the internal system temperature is too hot, the concentrator will display this message and shut down.

While it is unlikely that the system will become this hot, the risk of this situation can be minimized by operating the unit in a comfortable environment and ensuring the intake and exhaust are clear of obstructions. The intake particulate filter should be kept clean, and there should be no filter in the exhaust vent. If this error regularly occurs, please contact OxygenToGo Customer Care for further instruction. How does the EverGo™ portable concentrator work (produce oxygen)? The Respironics EverGo portable concentrator separates oxygen from room air and delivers it through a single lumen cannula. Room air contains approximately 21 percent oxygen and 79 percent nitrogen. By passing the air through a series of molecular, bacterial and dust filters, EverGo removes nitrogen and stores nearly pure (therapeutic) oxygen. How long can EverGo operate on battery power? Its two rechargeable batteries provide up to 8 hours of oxygen while operating at a typical patient setting of two (20 breaths per minute).

See the chart below. What is EverGo’s oxygen producing capability? EverGo can deliver a maximum of 1050 ml/min. That is more oxygen per minute than any other portable concentrator available. What size is EverGo? It is about the size of a camera bag or small carry-on bag. 12” L x 6” W x 8.5” H (30.5 cm L x 15.25 cm W x 21.6 cm H) Can I use the EverGo while I sleep? Your doctor can determine whether or not the EverGo portable concentrator is appropriate for you while you sleep. An overnight pulse oximetry test may be necessary to measure your oxygen saturation level while using EverGo at night. What type of cannula works with EverGo? A standard single-lumen nasal cannula and tubing (not supplied) should be used to deliver oxygen from EverGo. The device works with cannula tubing up to 30 ft. (9.1 m). How is EverGo controlled? All product operation occurs via an easy-to-read, simple-to-operate touch screen interface. The touch screen is a back-lit liquid crystal display (LCD) located on the top of EverGo.
