1.0 Introduction

This unit is not a life-support device. Geriatric, pediatric, or any other
patient unable to communicate discomfort while using this oxygen
concentrator may require additional monitoring. Patients with hearing
and/or sight impairments may need assistance with monitoring the
alarms.

This device supplies high-concentration oxygen that promotes rapid
burning. Do not allow smoking or open flames within the same room of
(1) this device, or (2) any oxygen-carrying accessory. Failure to observe
this warning can result in severe fire, property damage, and/or cause
physical injury or death.

Use no oil, grease, or petroleum-based or other flammable products on
or near nasal end of cannula or on the Intensity 10 unit. Oxygen
accelerates the combustion of flammable substances.

1.1 Equipment Provider Responsibility

All Equipment Providers of the NewLife® Intensity 10 Oxygen Concentrator must assume
responsibilities for handling, operational check-out, patient instruction, and oxygen
concentration checks. These responsibilities are outlined below and throughout this
manual.

As an Equipment Provider, you must do all of the following:

 Inspect the condition of each NewLife Intensity 10 unit immediately upon delivery

to your business location. Note any sign of damage on the delivery receipt, and
report it directly to both the freight company and AirSep Corporation immediately.

 Check the operation of each NewLife Intensity 10 before delivery to a patient.

Confirm the oxygen concentration level is within specifications, as referred to in
Section 2.4. (Test the battery and power disconnect alarm, as described in Section

2.3 of this manual.)

 Deliver NewLife Intensity 10 units only to patients authorized by a licensed health

care provider or physician’s prescription. The NewLife Intensity 10 must not be
used as a life-supporting device. A backup supply of oxygen must be available.

 Instruct patients how to use the NewLife Intensity 10 in conjunction with the Patient

Manual.

 Instruct patients to notify their licensed health care provider/physician if they

experience any signs of discomfort.

 Instruct each patient how to perform routine maintenance of the air intake gross

particle filter and how to check the alarm system battery. (Refer to Section 3.2.)

 Be available to provide service to each patient at any time.
 Maintain the NewLife Intensity 10 in accordance with Section 4.0.
 Establish and implement a protocol to check oxygen concentration.
 Repair components and replace parts only as outlined in this manual. Use only

AirSep parts for replacement in NewLife Intensity 10 Oxygen Concentrators.

 Refer to the NewLife Intensity 10 Product Warranty if parts replacement is required

within the warranty period.

As you read the manual, pay special attention to the WARNING, CAUTION, and NOTE
messages. They identify safety guidelines or other important information as follows:

Symbols are frequently used on equipment in preference to words with the intention of
lessening any possibility of misunderstanding caused by language differences. Symbols
can also permit easier comprehension of a concept within a restricted space.

Method for disposing of waste: All waste from the NewLife Intensity 10 (patient circuit,
etc.) must be disposed of using appropriate methods.

Method for disposing of the device: In order to preserve the environment, the
concentrator must only be disposed of using the appropriate methods.

Conformity with EN 60-601 (§ 6.8.2 b):

“The manufacturer, assembler, installer or importer are not considered to be responsible

themselves for the consequences on the safety, reliability and characteristics of a device
unless:

- The assembly, fitting, extensions, adjustments, modifications, or repairs have been
performed by persons authorized by the party in question.

- The electrical installation of the corresponding premises complies with IEC regulations.

- The device is used in accordance with the instructions for use.” If the replacement parts
used for the periodic servicing by an approved technician do not comply with the
manufacturer’s specifications, the latter is absolved from all responsibility in the event of
an accident. Do not open the device while in operation: risk of electrical shock. This
device complies with the requirements of the 93/42/EEC European directive but its
operation may be affected by other devices being used close by, such as diathermy and
high frequency electro-surgical equipment, defibrillators, short wave therapy equipment,
mobile telephones, CB and other portable devices, microwave ovens, induction plates or
even remote control toys, and more generally electromagnetic interferences, which exceed
the levels specified by the EN 60601-1-2 standard.

Classification

Type of protection against electric shock:

2.0 Operational Check and Oxygen Concentration Test

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.

2.1 Description of Operation

Air is drawn into the NewLife Intensity 10 Oxygen Concentrator through an external air
intake gross particulate 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 the compressor and passes through a heat exchanger. The heat exchanger reduces the
temperature 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 molecular
sieve enables it to physically attract (adsorb) nitrogen when air passes through this
material, thus producing high concentrated oxygen.

There are two sieve beds: while one produces high concentration oxygen, the other is
purged 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. The
NewLife Intensity 10 unit delivers up to 95.5% oxygen at flow rates from 2-10 lpm.

2.2 Operation Check

AirSep tests every NewLife Intensity 10 Oxygen Concentrator thoroughly after
manufacture. You must perform the following test to ensure that no damage occurred in
shipping or handling.

1. Open and inspect all cartons (that contain units) upon delivery. Unpack the unit
and remove it from the carton. Inspect the unit itself for damage. If the exterior of

a unit’s carton is damaged, or the unit itself is damaged, note it on the freight bill

signed by the driver.

2. Connect unit to power, and set the I/0 power switch to the “I” position. Check to
see that the following occurs:

a. A continuous alarm sounds for approximately five seconds. See the

troubleshooting chart in Section 6.3 of this manual if the unit’s

alarm does anything other than sound for five seconds.
b. The compressor runs and flow is indicated in flowmeter.
c. OPTIONAL: The Oxygen Monitor’s amber light remains on until

the oxygen concentration reaches 85% ±3% (approximately two

minutes). Perform an oxygen concentration test, as described in

Section 2.4.

2.3 Alarm System

The NewLife Intensity 10 Oxygen Concentrator is equipped with a battery-powered alarm
system, which sounds a continuous and loud alarm when a power failure occurs. It sounds
an intermittent alarm if the high or low pressure indicators are activated or if the optional
