    What is a HomeFill system?

    The HomeFill(TM) home oxygen system allows patients to fill their own high-pressure cylinders from a concentrator. The ability to fill their own cylinders gives ambulatory patients greater independence and freedom from oxygen deliveries.

    How does the HomeFill system work?

    The HomeFill is a multi-stage pump that simply and safely compresses oxygen from your concentrator into portable oxygen cylinders in sizes M2, ML4, ML6, M6, M9(C) and D.

    Get to Know Your Equipment

    The HomeFill system is comprised of the following equipment:

    HomeFill Compressor - the HomeFill Compressor connects to an Oxygen Concentrator to fill portable tanks.

    Oxygen Concentrator - purifies room air to deliver higher oxygen concentration

    Tank - a portable vessel that stores oxygen for use outside of the home

    Regulator - attachment that sits on the tank's valve that determines the flow of oxygen

    Compressor Orientation Checklist

    Each time the HomeFill Compressor is used to fill a cylinder, complete the following checklist:

    • Ensure the concentrator has been "on" for at least 30 minutes.
    • Perform the prefill inspection on the cylinder.
    • Connect the cylinder to the compressor.
    • Push the compressor power switch to the "On" position.
    • Examine the indicator lights on the control panel.
    • Disconnect and remove the full cylinder.
    • Push the compressor switch to the "Off" position.
    • If filling another cylinder, repeat this checklist.

    Pre-Fill Inspection of the Cylinder

    • Examine the outside of the cylinder for the following conditions, and replace the cylinder if they exist:
      • Dents or dings
      • Arc burns
      • Oil or grease
      • Any other signs of damage that might cause a cylinder to be unacceptable or unsafe for use.
    • Examine the cylinder for evidence of fire or thermal damage. Evidence includes charring or blistering of the paint, or other protective coating or heat sensitive indicator. If fire or thermal damage is found, replace the cylinder.
    • Inspect the cylinder/regulator or assembly for the following and replace if found: 
      • Debris, oil or grease
      • Noticeable signs of damage
      • Signs of corrosion inside the valve
      • Signs of excessive heat or fire damage

  • Filling Instructions

    Always refer to your equipment's user manual for more detailed instructions. Before filling, review the Compressor & Pre-Fill Checklists in section "About Your HomeFill"

    Connecting/Disconnecting the Cylinder from Compressor

    1. Examine the cylinder gauge. If the cylinder pressure is less than 1500 psig, proceed to STEP 2. If the cylinder pressure is greater than 1500 psig, DO NOT attempt to top off this cylinder. It may not fill.
    2. Set the regulator flow dial on the cylinder to Off.
    3. Remove the cylinder and connector fillport covers (if present).
    4. Momentarily push DOWN on the outer ring (sleeve) of the connector fillport until GREEN dots are visible to reset the connector.
    5. Grasp the cylinder in the area behind the cylinder fillport
    6. Position the cylinder in the compressor cradle
    7. Align the cylinder fillport with the connector fillport
    8. Pull UP on the outer ring (sleeve) of the connector fillport while pushing DOWN on the cylinder to couple the cylinder fillport into the connector fillport

    Note: If the outer ring (sleeve) is in the UP position (GREEN dots not visible), the connector fillport will not be able to accept the cylinder fillport. Pushing DOWN momentarily will reset the connector fillport (GREEN dots visible) to accept the cylinder fillport.

    Disconnecting the Cylinder from Compressor

    1. Press the compressor power switch to the Off (O) position.
    2. Grasp the cylinder in the area behind the cylinder fillport.
    3. With the other hand, grasp the outer ring (sleeve) of the connector fillport and push DOWN.
    4. Lift up on the cylinder to remove from the connector fillport.
    5. When the cylinder fillport is disconnected from the connector fillport, release the outer ring (sleeve) of the connector fillport and use two hands to remove the cylinder from the compressor cradle.
    6. Place the fillport covers onto the connector fillport and cylinder fillport.
    7. Examine the cylinder gauge to ensure cylinder is full (needle pointing into GREEN area). If the cylinder is not full, perform the following:
    8. Repeat Connecting the Cylinder to the Compressor..
    9. If cylinder is not full after second attempt to fill, contact Us.

    WARNING: The fillport cover on the connector fillport and the cylinder fillport MUST be replaced after filling and whenever not in use. If either of the fillport covers are missing contact us before using.

    Turning the Compressor On

    1. Make sure the concentrator is On.
    2. The concentrator flow rate to the patient MUST be set at maximum: 3 L/min or less for Platinum 5, XL, and Perfecto2 and 5 L/min for Platinum 10. Otherwise, the oxygen level to the compressor will be <90% and the compressor will not fill the cylinder.
    3. Set the concentrator flow rate to the patient to 3 L/min or less for Platinum 5, XL, and Perfecto2 and 5 L/min for Platinum 10. Refer to the concentrator Owner’s Manual.
    4. Make sure the cylinder is connected to the compressor.
    5. Push the power switch on the control panel to the On position.
    6. Examine the control panel. The following sequence of events should occur
      1. 0‐3 minutes ‐ The O2 Below Normal (YELLOW) light will be lit while the compressor warms up.
      2. After three minutes ‐ The FILLING (GREEN) light will be on while the cylinder is filling.
      3. The FULL (GREEN) light will be on when the cylinder is finished filling. Proceed to STEP 6.
    7. Remove the full cylinder. Refer to Disconnecting the Cylinder from the Compressor.
    8. Push the power switch to the Off (O) position.

    NOTE: The O2  BELOW NORMAL (YELLOW) light may come on if the oxygen level from the concentrator has not yet reached or drops below 90%. The compressor will begin or resume filling when the oxygen level reaches 90%.
