dynarex 207-163 5 Liter Oxygen Concentrator
Product Introduction
This medical Oxygen Concentrator is a device that extracts oxygen from atmospheric air. It is an electrically-powered molecular sieve (artificial zeolite) used to separate nitrogen from ambient air. It could be used in a variety of settings. The oxygen concentrator can supply a patient with a steady oxygen flow.
Symbols
The following table is a list of symbols and definitions that are used with
the Dynarex Oxygen Concentrator.
Warnings
For your safety, the Oxygen Concentrator must be used according to the
prescription determined by your physician. It is very important to follow your
oxygen prescription. Do not increase or decrease the flow of oxygen – consult
your physician. Your delivery settings of the Oxygen Concentrator should be
periodically reassessed for the effectiveness of therapy. If a warning light
is lit, or the concentrator is not operating properly, or if you feel
discomfort or are experiencing a medical emergency while undergoing oxygen
therapy, seek medical assistance immediately. Under certain circumstances,
oxygen therapy can be hazardous. Seek medical advice before using an Oxygen
Concentrator. This device manufactures high concentration oxygen, which
promotes rapid burning. Keep Oxygen Concentrator far away from open flames. Do
not use in the presence of a flammable anesthetic mixture with air or with
oxygen or nitrous oxide. Smoking during oxygen therapy is dangerous and is
likely to result in facial burns or death. Do not allow smoking within the
same room where the Oxygen Concentrator or any oxygen-carrying accessories are
located. If you intend to smoke, you must always turn the oxygen concentrator
off, remove the cannula and leave the room where either the cannula or mask or
the Oxygen Concentrator is located. If unable to leave the room, you must wait
10 minutes after you have turned off the Oxygen Concentrator before smoking.
Turn the Oxygen Concentrator off when not in use to prevent oxygen enrichment.
Do not leave the nasal cannula or mask on bed coverings or chair cushions when
not in use. Never use petroleum or oil-based lotions or salves to avoid the
risk of fire and burns. Do not lubricate fittings, connections, tubing or
other accessories of the Oxygen Concentrator to avoid the risk of fire and
burns. To prevent product damage, do not attempt to operate the unit without
the air filter or while the filter is still damp. Only use service parts
recommended by the manufacturer to ensure proper function Secure oxygen tubing
and power supply cords to prevent tripping hazards and reduce the possibility
of entanglement or strangulation. Care should be taken to prevent the unit
from getting wet or allowing water to enter the unit. Do not place the Oxygen
Concentrator in surroundings where its airflow is obstructed. Do not place
items on top of the concentrator. Keep a clearance of at least 32″ around the
unit. When the device is used under extreme operating conditions, the
temperature near the exhaust vents on the bottom of the unit may reach 145˚F
(63˚C). Do not use the unit if the power cord is damaged. Before attempting
any cleaning procedures, turn the unit “OFF”. Do not service or clean this
device while in use with a patient. Electrical shock hazard. Do not remove the
cover while the unit is plugged in. Only your equipment provider or a
qualified service technician should remove the covers or service the unit. The
use of harsh chemicals (including alcohol) is not recommended. If bactericidal
cleaning is required, a non-alcohol-based product should be used to avoid
inadvertent damage. Use only the voltage specified on the rating label. Always
place the concentrator on a hard surface. Never place the concentrator on a
surface such as bed or couch, where the concentrator may tip or fall. NEVER
leave the concentrator unattended when plugged in. Allow the unit to run until
it reaches the proper purity level. a service technician should remove the
covers or service the unit. The use of harsh chemicals (including alcohol) is
not recommended. If bactericidal cleaning is required, a non-alcohol-based
product should be used to avoid inadvertent damage. Use only the voltage

where the concentrator may tip or fall. NEVER leave the concentrator
unattended when plugged in. Allow the unit to run until it reaches the prop-er
purity level.
- CAUTION: Radio Frequency Interference. Most electronic equipment is influenced by Radio Frequency Interference (RFI). When there is strong electromagnetic interference, the LCD (Liquid Crystal Dis-play) may be slightly affected, but the Oxygen Concentrator is still running. ALWAYS exercise CAUTION with regard to the use of portable communications equipment in the area around such equipment.
- NOTE: When turned off allow at least 5 minutes before restarting the concentrator.

-
Oxygen Flow Meter – The location of float in the oxygen flow meter shows the outlet oxygen flow (L/min.).
-
Flow Meter Knob – It adjusts and controls the outlet oxygen flow.
-
Air Filter – Prevents dirt, dust, and lint from entering your unit.
-
LCD – Display the total working hours of the oxygen concentrator.
-

Operation Instructions
- If used with a humidifier, unscrew the bottle cover from the humidifier in a clockwise direction, pour in proper distilled water between the max line and the min line, then re-connect the top cover to the humidifier bottle, as shown in Figure 3 and Figure 4.
- Connect the nasal oxygen cannula to the humidifier outlet nozzle. Set the nasal oxygen cannula over the patient’s ears, and insert the nasal oxygen cannula into the patient’s nostrils to absorb oxygen.
- Set the I/O power switch to the “I” position to turn the unit on, at the same time the PO lamp will light.
- To set the flow of supplemental oxygen, turn the knob of the oxygen flow meter switch left or right until the ball inside the flow meter centers on the flow line number of the prescribed oxygen flow. Flow value:
Flow value: can be set from0.5~5 L/min on the flow meter, as shown in Figure 5.
Alarms and Safety Devices
- Power failure alarm – In case of a loss of power an audible alarm is activated and a red indicator light will illuminate.
- Low & high-pressure alarm – There is a pressure sensor on the mainboard to check the system pressure, when the pressure is lower than 0.1 Mpa, or higher than 0.23 Mpa, there is an audible alarm and a red indicator light will illuminate.
- Low oxygen concentration alarm –The oxygen concentration will rise to the normal level within five minutes of operation. If oxygen purity falls below 85%, there is an audible alarm and a red indicator light will illuminate.
- Low flowrate alarm – There is a sensor to check the flow rate, if the flow rate falls lower than 0.5 L/min, a red light turns on to indicate a low flow rate.
Maintenance
- Cabinet Filter – It is critical to inspect the cabinet filter on a routine basis. Remove the cabinet filters, clean with mild soap or detergent, rinse thoroughly and ensure filters are dry before reinstalling, as shown in Figure 6.
- Change the Air Intake Filter – Change the air intake filter when it is too dirty or turns black
- Reset Circuit Breaker – The circuit breaker is an electrical switch designed to protect the electrical circuit from damage caused by excess current. When excess current is present the circuit breaker will trip, blocking the flow of electricity. It must be reset manually by pushing the breaker button in
