General Safety Instructions
Production and use of oxygen
Oxygen is not a flammable gas, but accelerates the combustion of materials. To prevent fire risks, the MARK5 NUVO should be kept away from flames, incandescent sources or sources of heat (cigarettes) and combustible products such as oil, grease, solvents, aerosols, etc.
Do not use in an explosive atmosphere.
Prevent oxygen from accumulating on upholstered seats or any other fabric. If the concentrator operates without being administered to a patient, locate it so that the flow of gas generated is dissipated into the air.
Locate the equipment in a free space (filter to the rear and below) which is well ventilated and free of fumes or atmospheric pollution.
Use and Maintenance of the Device
Use the electric cable provided and check that the voltage of the mains socket used complies with the electrical characteristics of the appliance indicated on the manufacturers plate on the rear of the appliance.

2.0Operational Check and Concentration Test
2.1Description of Operation
Air enters the Mark5 Nuvo® Oxygen Concentrator through an external cooling air intake filter. This filtered air enters the compressor via a suction resonator and fine filter, which quiets the suction sounds made by the compressor. Pressurized air then exits the compressor and passes through a heat exchanger into an air tank. The heat exchanger reduces the temperature of the compressed air and the air tank stores air when feed is interrupted. Next, a rotary poppet feed valve directs the air into one of two sieve beds that contain molecular sieve. The special characteristic property of molecular sieve is that it physically attracts (adsorbs) nitrogen when air passes through this material, thus enabling the production of high purity oxygen.
There are two sieve beds or adsorbent columns; while one produces high purity oxygen, the other is purged of the nitrogen it adsorbed (collected) while it was producing oxygen. Each column produces oxygen for approximately four seconds and delivers it to the product storage volume in the end of the column. Oxygen exits the adsorbent column through a pressure regulator, flow control valve, flow meter, and final product filter. The flow control valve, which is part of the flow meter, controls the flow rate of oxygen delivered to the patient. The Mark5 Nuvo® unit 2010-2225 Rev — B Page 9 of 59
delivers up to 95% oxygen concentration at flow rates from 1 to 5 l/min. The remaining constituents of the product gas stream are nitrogen and argon, both of which are part of the air we breathe, are inert and are completely safe.
2.2Operational Check
Nidek Medical runs each device through a burn in period and tests every Mark5 Nuvo® Oxygen Concentrator thoroughly after manufacture before releasing for shipment. As the home service provider, it is your responsibility to perform the following test to ensure that no damage occurred in shipping or handling.
1.Open and inspect all concentrator cartons upon receipt. Unpack each unit and remove it from its carton. Inspect the unit itself for damage. If the exterior of the carton is damaged, or the unit itself is damaged, note it on the freight bill signed by the driver.
●Before plugging the unit into the wall outlet, actuate the I/0
(ON/OFF) switch to the I (ON) position and note that the audible alarm sounds continuously. (See Section 2.3). Move the switch to the 0 (OFF) position.
2.Plug in the power cord of the unit, and set the I/0 (ON/OFF) switch to the I (ON) position. Check to see that the following occurs:
●The compressor runs, listen for the sound.
●Exhaust air flows out of the bottom of the unit.
●OPTIONAL for Units Equipped with Oxygen Concentration Status
Indicator (OCSI): The OCSI green light remains off until the oxygen concentration reaches 85% ± 3% (82% ± 2% for 50 Hz units) (approximately two minutes).
3.Turn the flow meter adjustment knob counterclockwise until it stops (wide open). The flow meter should register in excess of 5.5 liters/min. If not, refer to Section 5.8 to adjust the product regulator.
4 Perform an oxygen concentration test, as described in Section 2.4.
2.3Alarm System
The Mark5 Nuvo® Oxygen Concentrator is equipped with a battery-powered alarm system, which sounds a continuous and loud alarm when a power failure occurs or when one or more cycle variables are not within specification. It sounds an alarm if the high or low pressure indicators are activated or if the optional OCSI detects lower than predetermined levels of oxygen concentration. The alarm remains on until you correct the alarm condition or you set the I/0 (ON/OFF) switch to the 0 (OFF) position. Refer to Section 6.0 for a list of probable alarm causes,
Page 10 of 59 |
2010-2225 Rev — B |
2.3.1 Battery Test
The Mark5 Nuvo® battery can be checked by observing that the continuous alarm sounds when the I/0 (ON/OFF) switch is moved to the I (ON) position when the unit is unplugged from the wall outlet.
2.3.2 Power Failure Alarm Test
To test the power failure alarm, perform the following actions:
Unplug the power cord from the wall outlet, and set the I/0 (ON/OFF) switch to the I (ON) position.
This should immediately activate the audible alarm. If it does not, refer to the troubleshooting chart in Section 6.0 of this manual.
2.4Oxygen Concentration Test and Specification
To ensure that the output of oxygen from the device is within specification, you must perform an oxygen concentration test. Test the unit upon delivery to a patient and at periodic intervals. Home Service Providers, based on their expertise and documentation, may establish and implement their own plans for checking oxygen concentration. The interval established may be longer or shorter than 90 days, which is Nidek Medical’s default time period for providers who do not choose to establish their own plan.
1.If an oxygen humidifier bottle is used, remove it from the oxygen outlet.
2.Connect a calibrated oxygen concentration analyzer to the oxygen outlet.
3.Set the I/0 (ON/OFF) power switch to the I (ON) position. (It takes approximately five minutes for the oxygen concentration to stabilize.) Take oxygen concentration readings over a period of several minutes to reduce any cyclic variations
4.Verify that the product flow rate delivered by the unit matches the patient’s prescription and does not exceed the capacity of the unit.
5.Disconnect the oxygen analyzer, and reconnect the humidifier bottle (if used) and any other equipment / accessories that may be required.
6.Adjust the flow meter adjustment knob to the prescribed flow rate.
NOTE
Do not measure oxygen concentration output after the product stream passes through a humidifier bottle, erroneous readings will result and your oxygen concentration measuring device might be damaged.

3.0Patient Instructions
3.1General Instructions
It is important that patients thoroughly understand how to operate the Nidek Medical Mark5 Nuvo® unit. This enables proper treatment as prescribed by a qualified, licensed physician. You must explain that the purpose of this therapy is to alleviate symptoms. If patients experience any discomfort or the unit alarms, they must notify their Home Service Provider and/or physician immediately. You, as the Home Service Provider, are responsible to see that each patient receives the Patient Manual. Explain each step in the operation of the unit to the patient in reference to this manual.
3.2Routine Maintenance by the Patient
To ensure accurate output and efficient operation of the unit, the patient must perform two simple routine maintenance tasks:
•Clean the cabinet air filter
•Check the alarm system battery
3.2.1Cleaning the Cabinet Air Filter
NOTE:
The patient must clean this filter weekly, as described below. The filter may require daily cleaning if the Mark5 Nuvo® unit operates in a harsh environment such as a house heated by wood, kerosene, or oil, or one with excessive cigarette smoke.
1Remove the dirty cabinet air filter from the back of the Mark5 Nuvo® unit.

3.2.2 Checking the Alarm System Battery
See Procedure described in Paragraph 2.3.1
4.0Home Service Provider Maintenance
4.1Routine Maintenance
The Mark5 Nuvo® unit has two filters and a 9-volt battery that require scheduled maintenance and replacement.
To ensure that the output of oxygen from the unit is within specification, you must perform an oxygen concentration test. Test the unit upon delivery to a patient and at periodic intervals. Home Service Providers, based on their expertise and documentation, may establish and implement their own practices for checking oxygen concentration. Consult Nidek Medical’s Service and Maintenance Log (A- 15) for the recommended intervals for testing.
Nidek Medical does not require preventive maintenance on the concentrator. You do not need to perform any maintenance as long as the Mark5 Nuvo® unit remains within specifications at the prescribed flow rate. (Refer to Section 2.4)
Cabinet Air Filter
The external cabinet air filter is located on the back of the unit, You can easily remove it by hand. Instruct the patient to clean this filter weekly. (Refer to Section 3.2.1.)
NOTE
The filter may require more frequent cleaning if the Mark5 Nuvo® unit operates in a harsh environment such as a house heated by wood, kerosene, or oil, or one with excessive cooking, cigarette smoke or atmospheric dust.
4.1.2 Final Product Filter Replacement
The final product filter does not require periodic replacement; it needs to be replaced only if it restricts oxygen flow. It is suggested that it be replaced whenever the sieve module is repaired or replaced and after the compressor is rebuilt.
1.Set the I/0 (ON/OFF) switch to the 0 (OFF) position, and unplug the power cord.
2.Remove the cabinet back to locate the final product filter.
NOTE: Observe the position of the filter before removal.
3.Separate the silicone tubing from both sides of the filter.
4.Install the new filter with the inlet side in the same position as before. Push the tubing together so that it overlaps the barbs of the final product filter

connections.
5.Record information about the final product filter replacement in Appendix 15 of this manual and online at www.nidekmedical.com under the ‘Maintenance Log’ tab.
6.Reinstall the cabinet back.
4.1.3 Inlet Air Filter Replacement
The inlet air filter requires inspection at each patient visit. The filter should be replaced annually, or more often depending on environment.
1.Set the unit I/0 (ON/OFF) switch to the 0 (OFF) position, and unplug the power cord.
2.Remove the rear cabinet access panel to locate the inlet air filter.
3.Remove filter from the unit, and replace with a new filter.
4.Record information about the filter replacement in Appendix 15 of this manual and online at www.nidekmedical.com under the ‘Maintenance Log’ tab.
5.Reinstall the access panel.
4.1.4 Battery Replacement
Each time the standard Mark5 Nuvo® unit is turned on, the alarm must sound loudly for approximately five seconds to indicate a good battery. An alarm that does anything other than sound loudly for five seconds indicates a weak battery and requires replacement. For units with OCSI, actuate the switch with the power cord unplugged to test the battery.
To replace the battery, take the following steps:
1.Set the I/0 (ON/OFF) switch to the 0 (OFF) position, and unplug the power cord.
2.Remove the access panel in the cabinet back.
3.Pull the battery from the mounting slot and remove the connection wires.
4.Attach the new battery to the connector and reinsert it into the mounting slot.
5.Set the I/0 (ON/OFF) switch to the I (ON) position to test the alarm.
6.Record the battery replacement information in Appendix 15 of this manual and online at www.nidekmedical.com under the ‘Maintenance Log’ tab.
7.Reinstall the access panel.
4.1.5 Wick Replacement
The wick is installed in the process air stream of the unit, connected to the air tank, to assist with removal of moisture from the air. This helps prevent premature contamination of the sieve beds, particularly in humid climates. The wick should be replaced at each compressor service / module replacement; it is suggested that more frequent replacement be done in very humid climates. The wick is located in a bushing located just to the right of the gearmotor. It is installed in a quick release fitting. Pull the fitting from the bushing by hand – it may require several pounds of force, remove the wick and install a new one in its place. Re-insert the wick end and fitting into the bushing so the wick is totally below the base plate surface.

4.1.6 Recording Maintenance
As the Home Service Provider, it is suggested that you record all routine maintenance and repairs performed on the Mark5 Nuvo® unit, including hours and dates of service in Appendix 15 of this manual and online at www.nidekmedical.com under the ‘Maintenance Log’ tab.
4.2Cleaning and Infection Control
With the growing concern about possible cross infection from home oxygen equipment (i.e.. oxygen concentrators) from one home care patient to another, appropriate cautions should be exercised.
The organisms of most concern are M. Tuberculosis, HIV, and Viral Hepatitis. These are potentially pathogenic.
Tuberculosis can survive outside of the human body, but its mode of transmission is by droplet nuclei. When infected individuals cough, they release droplet nuclei into the air, and these carry the Tuberculosis organism. Another person may breathe in these droplet nuclei, but prolonged exposure to the infected person is usually necessary for infection to occur.
HIV and Viral Hepatitis are both viruses, which are not living cells themselves but which can duplicate when in a living “host” cell. Both of these organisms are usually passed on by person-to-person contact, and both need to be in the human body to survive. Once outside the body, viruses can survive for only a short period of time.
4.2.1 Preparing for New Patient Use
When you remove the Mark5 Nuvo® from a patient’s home, always dispose of the used nasal cannula and humidifier bottle. Clean the exterior of the Mark5 Nuvo® with a soapy water solution or commercial detergent cleaner to remove any gross debris, organic or otherwise. Be careful not to get any liquid into the interior of the unit.
Next, clean the exterior with either a common chemical disinfectant or a bleach solution* and allow it to air dry. For the bleach solution, wear eye and skin protection to prevent exposure to the chlorine. Retest the Mark5 Nuvo® before you return it to your inventory.
Replace the cabinet air filter between each patient’s use or clean with warm soapy water if it is in good condition. Clean this filter at least once per week or more frequently if operated in a dusty environment.
*Make the bleach solution a 1:100 dilution of 5.25% sodium hypochlorite. Mix one part household bleach (e.g. Clorox) with 99 parts cold tap water. To measure the

solution easily, take 1/4 cup of household bleach, and mix it with a gallon of cold tap water. Allow the mixture to sit on potentially contaminated surfaces for 10 minutes.
5.0Service
5.1Components
The design of the Nidek Medical Mark5 Nuvo® Oxygen Concentrator allows for easy access and removal of most components. This allows you to perform scheduled maintenance, repair, and replacement of parts with minimal time and effort. The inlet air filter and battery are conveniently located inside the small access panel in the cabinet back.
CAUTION:
For your safety, be sure to set the I/0 (ON/OFF) switch to the 0 (OFF) position and unplug the power cord before you service the Mark5 Nuvo® Oxygen Concentrator.
NOTE: Record all scheduled maintenance. (Refer to Section 4.1.6.)
5.2Cabinet Removal
5.2.1 Removing Cabinet Back
To remove the cabinet back, remove two screws near the base (one on each side) and two inset screws at the top just under the handle.
5.2.2 Removing Cabinet Front
To remove the cabinet front, remove two screws near the base (one on each side) adjacent to the rear cabinet screws and two inset screws at the top just under the handle. It is necessary to remove the cabinet back to access the top screws.
5.2.3 Removing Control Panel
Eight screws hold the control panel in place; the front cover must be removed to access these screws. It is necessary to remove the electrical wiring and pneumatic tubing to fully release the control panel.
5.2.4 Main Structure
The weight and forces of the internal components rest solely on four parts: the main structure, the compressor plate, the base-plate and the base. These parts were specially designed and formed. They should never require replacement under normal use.

5.2.5 Caster Replacement
The casters are a push in type that does not require any fastener. Lay the device on its back to access the casters from the bottom. Pull them straight out away from the bottom.
5.3Compressor
The compressor is the pump within the oxygen concentrator that supplies air to the separation process performed by the sieve beds. The pressure generated by the compressor forces oxygen to flow out of the top of the sieve columns.
The compressor is the likely cause of two potential specific problems:
a.An insufficient amount of air is supplied to the process, and
b.An excessive sound level.
● Air Supply
Compressor output refers to how much compressed air the compressor can produce. This depends upon the model of the compressor, length of stroke, piston diameter, speed of rotation and condition of seals. The cup seals form the seal between the piston and the cylinder wall. As the cup seals wear, the output begins to gradually decrease. This reduction in compressor output results in less air, and thus less oxygen, entering the sieve beds. Therefore, the production of oxygen decreases.
Because this drop in oxygen production occurs over a long period of time, preventive maintenance on the compressor is not required.
You can continue a patient’s therapy on the Mark5 Nuvo® unit as long as the oxygen concentration level at the prescribed liter flow rate is within Nidek Medical’s specification limits. Refer to Section 2.4.

● Sound Level
The sound level is largely determined by the condition of the compressor’s bearings.
There are four bearings located within the compressor that allow the inner components of the compressor to rotate. If the bearings wear to the point that they become loose and noisy, the compressor becomes noticeably loud and needs servicing. The life of a compressor is determined primarily by its operating temperature. It is extremely important that the cabinet air filters are cleaned and replaced as required.
