• Disconnect the power cord from the electrical outlet before cleaning the housing of the HomeLox System.
• This equipment complies with IEC 60601-1-2 for electromagnetic compatibility for medical electrical
equipment and/or systems. This standard is designed to provide reasonable protection against harmful
interference in a typical medical installation. However, because of the proliferation of radio-frequency
transmitting equipment and other sources of electrical noise in health care and other environments, it is
possible that high levels of such interference due to close proximity or strength of a source might disrupt
the performance of this device. Medical electrical equipment needs special precautions regarding EMC,
and all equipment must be installed and put into service according to the EMC information specified in
this manual.
• Take precautions to prevent electrostatic discharge (ESD). Precautionary procedures include methods
to prevent buildup of electrostatic discharge (e.g., air conditioning, humidification, conductive floor
coverings, and non-synthetic clothing), discharging one’s body to the frame of the equipment or system or
to earth or a large metal object, and bonding oneself by means of a wrist strap to the equipment or system,
or to earth.

HomeLox User Manual
How the System Works
Your Respironics HomeLox is a device that can generate and store liquid oxygen in your home by converting
the oxygen gas, generated from an integrated oxygen concentrator, to its liquid form. e liquid oxygen stored
in this device can then be transferred to your Respironics GoLox-93 portable liquid oxygen device for your use
as a source of ambulatory oxygen. e HomeLox is only a liquid oxygen reservoir for lling a portable unit and
will not provide any ability for you to breathe oxygen gas directly from it. is device is not intended to be life
supporting nor life sustaining.
Your HomeLox is made up of an oxygen generator, low temperature refrigeration system and an insulated liquid
oxygen storage bottle. e HomeLox operates by taking oxygen gas that it produces from room air and turning
it into liquid oxygen by lowering its temperature to -279 F (-173C) using refrigeration. At this temperature,
gaseous oxygen becomes liquid oxygen. e device then stores this liquid oxygen until you are ready to ll your
GoLox-93.
When your GoLox-93 is properly attached to the HomeLox, the liquid oxygen will be transferred to your
GoLox-93 in approximately 1 to 2 minutes. To be sure you will always have liquid oxygen available for your
use, the HomeLox monitors the amount of liquid oxygen stored inside it. When your available supply has been
reduced to a level set by your equipment provider, the HomeLox will automatically turn on and run until it has
completely relled itself and then will turn o.
To ensure the correct use of this device, please read the information in this manual carefully before trying
to operate this device. After reading this manual, keep it in a safe place where you can refer to it anytime a
question arises.

Filling Your GoLox-93
Warning: Do not leave the GoLox-93 unattended while it is lling.
Warning: Risk of electrical shock if unit is accidentally immersed or if uids are spilled on the HomeLox device.
Do not allow uids to come in contact with the device, as they may create a shock hazard.
If the HomeLox has been installed with liquid oxygen already in the device, you may ll the GoLox-93
immediately. If the HomeLox has been installed without liquid oxygen, wait 24 hours before lling the
GoLox-93. When the rst batch of liquid oxygen is stored in the HomeLox insulated liquid oxygen storage
bottle, the control panel light next to Ewill turn on. In the event of a temporary power loss, you can still ll
your GoLox-93 with oxygen by following the steps below.
1. Wipe the GoLox-93 and HomeLox connectors with a clean, dry,
lint-free cloth to remove any residual dirt or moisture.
Warning: Do not depress the HomeLox ll valve while wiping it clean.
2. Stand in front of the HomeLox facing the control panel.
3. Rotate the turntable on top of the HomeLox counter-clockwise until
it stops. Notice that the indicator line on the turntable is aligned
with the line on the HomeLox.
4. Make sure the Vent Fill Lever on the back of the
GoLox-93 is in the upright, closed position.
5. Make sure the Flow Control Knob is in
the OFF position.
6. Place the GoLox-93 in the recess in the turntable.
7. Rotate the turntable clockwise until it stops. Notice that the
indicator line on the turntable is aligned with the line on the
HomeLox. The portable unit and HomeLox are now connected and
ready for liquid oxygen to be transferred from the HomeLox into the
GoLox-93.

HomeLox User Manual
Warning: Make sure the devices are properly connected before lling the GoLox-93.
8. Pull down the Vent Fill Lever on the back of the GoLox-93 so filling
can begin. Liquid oxygen is now flowing from the liquefaction unit
to the GoLox-93. You will hear a hissing sound as gaseous oxygen
escapes. This is normal. You may also see a white vapor near the
connection as the very cold oxygen comes in contact with the warm
air in the room. This is also normal.
Warning: Do not leave the GoLox-93 unattended while lling.
Warning: Do not smoke while the device is in use.
9. Allow filling to continue until the sound of venting stops, about 1-2
minutes. When the sound stops, it means that the
GoLox-93 is full and its internal shutoff valve has stopped receiving
liquid oxygen from the HomeLox.
10. Move the Vent Fill Lever on the back of the GoLox-93 to its closed,
upright position.
11. Rotate the turntable on the top of the HomeLox counter-clockwise
until it stops. Notice that the indicator lines on the turntable align
with the lines on the HomeLox.
12. Gently remove the GoLox-93 from the turntable.
(See the GoLox-93 User Manual for complete instructions.)
Warning: Frostbite may occur on contact with liquid oxygen, cold gaseous oxygen, or frosted parts. Do not
touch any frosted parts. See the Troubleshooting Guide on the next page for more information.
Warning: Always wait at least 15 minutes before attempting the next ll of your GoLox-93 to prevent
excessive frosting of the connections.
