Safety Instructions
3.1. Warnings Overview
1. The device must be used in the carry bag to provide protection from liquid intrusion
from rain and/or spills.
2. There is a risk of re associated with oxygen equipment and therapy. Do not use near
sparks or open ames.
3. The settings of Zen-Olite™ Portable Oxygen Concentrator RS-00600 might not corre-
spond with continuous ow oxygen.
4. The settings of other models or brands of portable oxygen concentrators do not cor-
respond with the settings of Zen-Olite™ Portable Oxygen Concentrator RS-00600.
5. Wind or strong drafts can adversely aect accurate delivery of oxygen therapy.
6. Geriatrics or any other patient unable to communicate discomfort can require addi-
tional monitoring to avoid harm.
7. Smoking (including e-cigarettes) during oxygen therapy is dangerous and is likely to
result in facial burns, serious injury or death of the patient and others from re. Do
not allow smoking or open ames within the same room as the portable oxygen con-
centrator or any oxygen carrying accessories. If you smoke, you must always turn the
oxygen concentrator o, remove the cannula and leave the room where either the
cannula or the concentrator is located. If unable to leave the room, you must wait 10
minutes after the ow of oxygen has been stopped.
8. Use only water based lotions that are oxygen compatible, before and during oxygen
therapy. Never use petroleum or oil based lotions or salves when operating the device
to avoid the risk of re and burns.
9. Open ames during oxygen therapy are dangerous and are likely to result in re or
death. Do not allow open ames within 3 metres (10 feet) of the oxygen concentrator
or any oxygen carrying accessory.
10. Oxygen makes it easier for a re to start and spread. Do not leave the nasal cannula
on bed coverings or chair cushions with the concentrator on, but not in use; the oxy-
gen will make the materials ammable. Turn the concentrator o when not in use to
prevent oxygen enrichment.
11. Explosion hazard. Do not use in the presence of ammable anaesthetics!
12. Do not use this device in the presence of pollutants or fumes.
13. Do not submerge this device in liquid. Do not expose to water or precipitation. Do not
expose to dusty conditions.
14. Do not use a device or any accessory that shows any sign of damage.

15. Do not use lubricants on this device or any of its accessories.
16. Use of this device at an altitude above 4,000 m (13,000 feet), or outside the tempera-
ture range of 5°C (41°F) to 40°C (104°F), or outside the humidity range of 5% to 93%
may adversely aect the owrate and percentage of oxygen and consequently the
quality of therapy. When not in use, the device should be stored in a clean, dry en-
vironment between -20°C and 60°C (-4°F and 140°F). Use and/or storage outside of
the valid conditions may damage the product. For more technical details see Chapter
1515. Technical Description.
17. Always ensure the battery is inserted before using this device.
18. If feeling ill or experiencing discomfort while using this device, contact your clinician
or seek medical assistance immediately to avoid harm.
19. Your home oxygen provider must verify the compatibility of the device and all acces-
sories used prior to use. To ensure you are receiving the therapeutic amount of oxy-
gen for your medical condition, the device and accessories must only be used after
one of more settings have been determined or prescribed for you at your specic ac-
tivity levels by a healthcare professional.
20. The electrical cord and tubing could present a tripping or strangulation hazard. Keep
away from children and pets.
21. Do not disassemble or modify this device or any of its accessories. Do not attempt any
maintenance other than tasks described in Chapter 10 -Troubleshooting. Disassembly
can create an electric shock hazard and will void the warranty. Contact your distribu-
tor for servicing by authorised personnel.
22. Use only spare parts recommended by the manufacturer to ensure proper function
and to avoid the risk of re and burns.
23. Do not repair or perform service work while the device is in use by the patient.
3.2. Cautions Overview
1. Keep away from heat sources (replaces, radiant heaters, etc.) that could cause the oper-
ating temperature at or near the device to exceed 40°C (104°F).
2. The display may be dicult to read under bright lighting conditions (sunlight, interior
lights, etc.), move away from direct light for viewing the display.
3. Keep away from lint or other loose material that could block the air intake vents.
4. Some countries restrict this device to be sold by or on an order of a prescribing clinician.
Please ensure you comply with relevant local laws.

6.2.1. Charging the Battery
CAUTION: Only charge the battery in this device or
in an approved charger section 6.1 - 6.1. Accessories
List.).
• Prior to using the device for the rst time, install
the battery as shown in Fig. 2. the battery will latch
when fully seated.
• Close the battery compartment ensuring the cover
latches to the device.
• Connect the AC/DC power supply by plugging the
round connector into the power input on the side
of the concentrator Fig. 3.
• Plug the other end of the AC/DC power supply into
a power outlet. Always use caution when inserting
the power supply to a wall outlet.
• The display shows .
The charger is universal and supports a wide variety
of international markets, so it can be plugged into an
outlet with 100-240V AC, 50-60 Hz.
Allow the battery to charge for a minimum of three
hours before use. Once completely charged, the de-
vice can run for up to 4 hours on battery power, at
setting 2 and 18 breaths per minute.
IMPORTANT: Battery run time may vary based on
breathing rate, age of battery, and environmental con-
ditions. See displayed text on device for battery charge
status.
IMPORTANT: Ensure power status icon (see Fig. 7) in-
dicates power is connected. If not, check that cord is
plugged in completely (see Chapter 10 - Trouble shooting for more information)
To maximise battery life and run time, avoid letting the battery deplete and use while con-
nected to a power source whenever possible. The internal battery will automatically charge
whenever the concentrator is connected to a power source. You can use the device while the
battery is charging. The LCD panel will indicate whether the device is operating on battery or
external AC power.
The fully charged battery will retain some level of charge for up to thirty days in this device
when not in use - see Caution below for battery removal/storage recommendation.

Operating Zen-Olite™
IMPORTANT: Read Chapter 3. Safety Instructions before using this device.
Zen-Olite™ Portable Oxygen Concentrator is designed for ease of use, with all functions ac-
cessed through just a few buttons on the control panel.
The device should be carried in its carry bag and used when positioned upright on a at sur-
face or on the oor while in the carry bag. The patient should be within the recommended
cannula length during use.
IMPORTANT: Except during startup and shutdown sequences, the backlight on the display screen
will remain o. Pressing any button will turn the backlight on briey. The backlight will also re-
main activated during an un-muted alarm condition.
7.1. Connecting a Nasal Cannula
CAUTION: Replace the cannula on a regular basis. Check with
your home oxygen provider or clinician to determine how of-
ten the cannula should be replaced.
CAUTION: Always follow the cannula manufacturer’s instruc-
tions for proper use.
Connect the tubing to the cannula port as shown in Fig. 5.
To connect the cannula to the patient, position the cannula tips
in patient’s nostrils and pass tubing over both ears and under
chin. Follow manufacturer’s instructions.
Slide adapter up tubing to adjust for comfort and t.
Once the cannula is secured, breathe normally through the nose.
Zen-Olite™ will detect a breath and deliver the oxygen during
inhalation.
IMPORTANT: Improper cannula placement may result in the device
being unable to detect all respiratory eorts of the patient. Ensure
cannula is connected securely and it has been fully inserted.
