There are three legs of the thermal event triangle: Fuel, Oxidizer and Ignition source. Two of thethree are present: Cotton fiber, skin lotion, facial hair and some plastics are hydrocarbon by
nature. Oxygen of 90% level runs through the plastic tubing to cannula. Therefore, DO NOT
allow sparking, flame from a lighter or match or other elevated temperatures beyond operational
range to reduce risk of thermal event.
To further improve safety, install OxySafe Kit Part No. 20628667 and 20628668.

O2 level inside Concentrator at or below 25% and in combination with highest safety test
temperature poses no threat to any thermal event.
Further protection is double insulation of internal wiring and sufficient electrical safety testing toensure equipment shutdown in overheat

2.0 Operational Check and Oxygen Concentration Test
2.1

Description of Operation
Air is drawn into the NewLife Oxygen Concentrator through an external air intake grossparticulate filter. Before this air enters the compressor, it passes through the unit’s suction
resonator which, quiets the compressor’s suction sound. Pressurized air then exits thecompressor and passes through a heat exchanger. The heat exchanger reduces thetemperature of the compressed air. Next, a two-way solenoid feed valve directs the air into
one of two sieve beds that contain molecular sieve. The unique property of molecularsieve enables it to physically attract (adsorb) nitrogen when air passes through thismaterial, thus producing high concentrated oxygen.
There are two sieve beds: while one produces high concentration oxygen, the other ispurged of the nitrogen it adsorbed (collected) during this pressure swing adsorption (PSA)
cycle. Each adsorber produces oxygen and delivers it to the product tank. Oxygen exits
the product tank through a pressure regulator, flow control valve, and flowmeter.

2.2

Operation Check
CAIRE tests every NewLife Oxygen Concentrator thoroughly after
manufacture. You must perform the following test to ensure that no damage occurred inshipping or handling.
Do not use extension cords with this unit or connect too many plugs
into the same electrical outlet. The use of extension cords could
adversely affect the performance of the device. Too many plugs into
one outlet can result in an overload to the electrical panel, causing the
breaker/fuse to activate or fire if the breaker or fuse fails to operate.
1.

Open and inspect all cartons (that contain units) upon delivery. Unpack the unit

25

MN240-1 Rev E

5.2.6 Caster Replacement
1. Remove the cabinet panels to expose the caster nut.
2. Remove the caster nut with a 9/16-inch socket. Use an extension for the two
front caster nut removals.
3. Install the new caster with original washer and securing nut.
4. Reconnect the cabinet panels.

5.3

Compressor
The compressor is the “pump” within the oxygen concentrator that pushes the room air
into the bottom of the sieve beds. This allows oxygen to flow out of the top of the sieve
beds in the NewLife unit.
Two different aspects of the compressor cause concern: the output and the sound level.
OutputCompressor output refers to how much compressed air the compressor can produce. Thisdepends upon the model of the compressor, stroke size, bore size, and cup seal condition.
The cup seals form the seal between the piston and the cylinder wall. As the cup seals
wear, the compressor’s output begins to gradually decrease. This reduction in compressor
output results in less air for the sieve beds. Therefore, the production of oxygen decreases.
Since this drop in oxygen production occurs over a long period of time, preventative
maintenance on the compressor is not required. You can continue a patient’s therapy on
the NewLife unit as long as that unit’s oxygen concentration level at the prescribed liter
flow rate is within CAIRE’s specifications.
Sound Level
The condition of the compressor’s cup seals, bearings, and other components can result in
an increased sound level. If the compressor’s cup seals or bearings wear to the point thatthey become noisy, the concentrator may become noticeably louder; therefore, compressor
service or exchange may be required.
The total acoustical energy emitted by a source per unit time is the sound power.
Sound pressure is the atmospheric pressure disturbance depending on the distance from thesource, strength of the source, and the environment.
Sound power is the cause of the unit emitting sound pressure waves (and does not changewith the distance from the unit), whereas sound pressure is the effect of the unit emitting
sound on the surrounding air as sound pressure waves (and does vary with distance).
The sound power level for the Elite is 60.2 dB(A) and 69 dB(A) for the Intensity 10.
The sound pressure level for the Elite is approximately 53 dB(A) and 58 dB(A) for the
Intensity 10.

a. EQ coil = 1,000ohms ± 10%
b. Feed/waste coil = 800ohms ± 10%
3. Elite and Intensity 220-240VAC units
a. EQ coil = 4,400ohms ± 10%
b. Feed/waste coil = 3,220ohms ± 10%
You can also determine which coil is not operating by checking each valve to see if
it becomes energized (magnetized) during unit operation.
To check for coil operation, follow the steps below:
1. Remove plastic cap securing the valve coil to the valve stem. (Do notremove coil).
2. With unit operating, hold a paperclip or the metal tip of a screwdriverslightly over the top of the valve stem located in the center of the coil.
3. When the coil becomes energized (magnetized) the paperclip or tip of thescrewdriver will be pulled down onto valve stem, indicating the valve coil isoperating.
4. If a coil is faulty, it will not become energized and require replacement.
To replace a solenoid valve coil, follow the steps below:

5.5

Sieve Beds
The NewLife unit utilizes two sieve beds, each containing molecular sieve. The uniqueproperty of molecular sieve enables it to physically attract nitrogen when air passes
through this material, thus producing highly concentrated oxygen.
While one sieve bed produces high concentration oxygen, the other is purged of thenitrogen it adsorbed (collected) while it concentrates oxygen. Each adsorber (sieve bed)
produces oxygen and delivers it to the product tank

5.5.1 Sieve Bed Replacement
Temporarily seal sieve bed openings with tape to prevent the sievematerial from being exposed to the moisture in room air. Prolonged
exposure to room air results in contamination and permanent damage
to the sieve material.
Leaks can be so small in air loss that oxygen concentration is notaffected immediately. The sieve material can become contaminatedgradually. Careful leak testing is important as the sieve material canbecome contaminated gradually with very small leaks.

If replacement is necessary, you must replace both sieve beds at thesame time.

6.0 Troubleshooting
6.1

Operating Pressure Test
Testing the operating pressure is a useful diagnostic tool when a concentrator produces low
oxygen concentration and requires servicing. Units functioning normally do not require
operating pressure tests.
Use the following procedure to test the operating pressure of the unit:
1.
Set the unit’s ON/OFF power switch to the OFF position and disconnect the power
cord.
2.
Remove the right-side panel.
3.
Locate the pressure test port location (black tube with plug in the end). Remove
plug and using a pressure test port adapter (KI257-1), connect the pressure gauge tothe test port.
Connect the unit to power and set the unit’s ON/OFF power switch to the ON
4.
position. Set the flowmeter to indicated maximum flow setting and allow theunit to run five minutes.
Observe the maximum and minimum readings on the pressure test gauge.
5.

Elite units:
The maximum reading should not exceed 32 PSIG (220.6 kPa).
The minimum reading should not exceed 10 PSIG (69 kPa).
Intensity 10 units:
The maximum reading should not exceed 34 PSIG (234 kPa).
The minimum reading should not be less than 10 PSIG (69 kPa).
When you turn the unit on, the system pressure always registers
higher than normal for the first few minutes of operation.

6.1.1 High Operating Pressure
Higher than normal operating pressure may indicate any of the following:· A restrictive exhaust muffler, which does not allow the waste (purge) gas toexit the system freely.
Operate the unit with the exhaust muffler disconnected to see if the operatingpressure returns to normal.
· An improperly operating circuit board or solenoid valve.
Confirm that the circuit board and solenoid valves function properly.
· Contaminated sieve beds.
Change the sieve beds.

39

MN240-1 Rev E

6.1.2 Low Operating Pressure
If the oxygen concentration level at the desired liter flow is within CAIRE’s
specifications, no service is required, even if operating pressure is low. If
concentration is below specifications at the desired liter flow rate with low
operating pressure, this may indicate any of the following:· A restriction in the intake resonator, which limits the amount of room air
available to the compressor.
Disconnect the braided tube at the compressor and allow the unit to operate
without the intake resonator to see if normal operating pressure returns.
· A compressor with reduced output.
If it is below specifications, replace or repair the compressor.
· An improperly operating circuit board or solenoid valve.
Confirm that the circuit board and solenoid valves function properly.
· A leak in the unit, which allows system pressure to escape.
Leak test unit.

6.2

General Troubleshooting
Before reviewing the troubleshooting chart, the following steps may be useful to isolate
any malfunctions:1.
Turn on the concentrator. If the unit does not turn on, refer to the troubleshooting
chart.
2.
For Intensity units verify the outlet pressure is 20 PSIG (138 kPa). If the outletpressure is not at 20 PSIG (138 kPa), the product regulator needs to be reset. Refer
to Section 5.9. For Elite units verify the flowmeter tops out at 5.5LPM. If theflowmeter ball goes lower or higher than 5.5LPM, the product regulator needs to bereset. Refer to Section 5.9.
3.
Make sure the unit is cycling properly by:
a. Observing the flowmeter ball is stable in flowmeter. (Flowmeter ball does not
move up and down more than ¼ of a liter.)b. Checking the operating pressure, please refer to section 6.1.
4.
Place your thumb over outlet of unit. The flowmeter ball should drop to the bottomof the flowmeter. If the ball does not drop completely to the bottom, there is a leakpresent between the top of the flowmeter and the outlet of the unit.
5.
If concentrator is not meeting specifications, make sure that the unit is leak-free by
testing all tubing connections and fittings with leak testing solution. Protect circuitboard(s) from solution and start leak test at the heat exchanger, following air flowof unit to oxygen outlet. Repair all leaks by tightening connections and fittings.
Set the concentrator at indicated maximum flow setting and connect pressure test
6.
gauge to unit. Determine pressure parameters by observing high and low pressure
points on the gauge. If pressures are high or low, refer to Section 6.1.
7.
Review troubleshooting chart to isolate and repair any other malfunctions.
