SETTING UP YOUR OXYGEN CONCENTRATOR

1. Position your unit near an electrical outlet convenient for the user.
   Keep the oxygen concentrator at least 5 feet away from heat source, sparks or any sources of flame.
   Do not connect to an electrical outlet controlled by a wall switch. NO other appliances should be plugged into the wall outlet.

2. Position your unit at least 6 inches away from walls, draperies, or any other objects that might prevent the proper flow of air in and out of your oxygen concentrator. The oxygen concentrator should be located in an area way from pollutants or fumes.
   Device operation above or outside of the voltage, temperature, humidity and/or altitude values specified may decrease oxygen concentration levels.

BEFORE OPERATING YOUR OXYGEN CONCENTRATOR

1. Before operating your unit always check to be sure the air filter (located on the back of your unit) is clean.
   Proper cleaning of this filter is discussed on page 14.

2. Attach the appropriate oxygen accessories to the oxygen outlet.
   Oxygen Tubing Connection:
   a. Connect the oxygen outlet connector onto the oxygen outlet.
   b. Attach the oxygen tubing directly to the connector. (Figure 5)

Oxygen Tubing Connection with Humidifier:
Only connect the humidifier if prescribed.

1. Fill the humidifier bottle with distilled water. Do not overfill.

2. Thread the wing nut located on the top of the humidifier bottle to the oxygen outlet so that it is suspended (Figure 6). Make sure it is securely tightened.

3. Attach the oxygen tubing directly to the humidifier bottle outlet fitting. (Figure 7)
   Your provider has prescribed either a nasal cannula, catheter, or face mask, in most cases, they are already attached to the oxygen tubing. If not, follow the manufacturer’s instructions for attachment.

4. Remove the power cord completely from the line cord strap, make sure the power switch is in Off position, and insert the plug into the wall outlet. The unit is double insulated to guard against electric shock.

If the humidifier and tubing are assembled correctly, and the flow setting is more than 1L/min, you will feel the oxygen flow through the cannula and bubbles will rise to the water surface.

OPERATING YOUR CONCENTRATOR

Special precautions need to be taken with Oxygen Concentrators and should be used according to the EMC information provided in this manual.
Oxygen can cause rapid burning when exposed to flames. Do not smoke while your oxygen concentrator is running, or when you are near a person utilizing oxygen therapy.
Keep the oxygen concentrator at least 5 feet away from hot objects, sparks, or any sources of fire.
Improper use of the power cord and plugs can cause burns, fire, or other electric shock hazards, do not use the unit if the power cord is damaged.

1. Press the power switch to “On” position. When unit is on, the Green Power light will illuminate, and the patient alert system —service Required light and audible signal —will briefly beep.
   If the Service Required light illuminates and the unit beeps but the unit is not operating, there is no power to the unit. Refer to the Minor Troubleshooting chart on page 17 and contact your provider if hecessary.
   If an audible low-frequency vibration sound is detected, the unit is not operating properly. Refer to the
   Minor Troubleshooting chart on page 17 and contact your provider if necessary.

2. Check the flow meter to make sure that the ball is centered on the line next to the prescribed number of your flow rate.

It is very important to follow your oxygen prescription. Do not increase or decrease the flow of oxygen without consulting your provider.
If the flow meter knob is turned clockwise, the flow decreases (and eventually will shut off the oxygen flow). If the knob is turned counterclockwise, the flow increases.
