NOTE
Notes are used to emphasize a characteristic or important consideration.

2.2 Warnings
 The operator should read and understand this entire manual before servicing or repairing the
device.
 The device is not intended for life support. Where the prescribing health care professional has
determined that an interruption in the supply of oxygen, for any reason, may have serious conse-
quences to the user, an alternate source of oxygen should be available for immediate use.
 Geriatric or any other patient unable to communicate discomfort, or hear or see the alarms while
using this device, may require additional monitoring.
 Oxygen supports combustion. Oxygen should not be used while smoking or in the presence of
an open flame.
 Do not use the device in the presence of a flammable anesthetic mixture in combination with ox-
ygen or air, or in the presence of nitrous oxide.
 Do not use oil or grease on the concentrator or its components as these substances, when com-
bined with oxygen, can greatly increase the potential for a fire hazard and personal injury.

 Periodically inspect electrical cords, cables, and the power supply for damage or signs of wear.
Discontinue use and replace if damaged.
 To avoid electric shock, unplug the device and remove the batteries before cleaning the bag. DO
NOT immerse the device in any fluids.
 Your home care provider is responsible for performing appropriate preventive maintenance at
the intervals recommended by Philips Respironics.
 For proper operation, your device requires unobstructed ventilation. Always make sure any
openings in the case are not obstructed by items, which may impede ventilation. Do not place
the device in a small closed space (such as a closet). The device should not be used adjacent to
or stacked with other equipment. For more information, contact your home care provider.
 Do not use an extension cord.
 Device operation above or outside of the voltage, breath rate, temperature, humidity and/or alti-
tude values specified may decrease oxygen concentration levels.
 Never drop or insert any object into any opening.
 Be aware that the electrical cord and/or tubing could present a tripping or strangulation hazard.
 Use only power cords supplied by Philips Respironics for this device. Use of power cords not
supplied by Philips Respironics may cause overheating or damage to the device and may result
in increased emissions or decreased immunity of the equipment or system.
 Do not operate without the battery installed and working. If primary power is lost with no battery
in place, the device will stop operating without warning the user. If the device must be operated
without the battery, the user should be aware that there is no backup power and no warning if

2.3 Cautions
 Do not immerse the device or allow any liquid to enter the enclosure.
 When the device is used in an automobile, disconnect it from the DC auto adapter outlet when
the automobile is turned off. Do not operate the device in a non-running vehicle for an extended
period, as this may deplete the vehicle’s battery and prevent the vehicle from starting. Do not
allow the device to be connected to the auto adapter outlet when starting the automobile. Wait
until the automobile starts before connecting the device to the DC power outlet. Secure the de-
vice securely when used in any moving vehicle. (The same cautions apply if using the DC
adapter outlet on a boat or recreational vehicle.)
 Turn off the device before removing the battery. The device should not be operated without the
battery installed. If the device is operated without the battery installed, the standard shutdown
routine will not be implemented when the power is disconnected prior to turning off the unit. This
can result in damage to the device.
 Only use the supplied shoulder strap to carry your device. With every use, verify that the case
and shoulder strap are in good condition.

6.3.14 UDI Labels

Per the Unique Device Identification (UDI) initiative, medical devices are required to be labeled with certain
device identifiers. The information provided on these labels allows the public to search and download
information from the Global Unique Device Identification Database (GUDID) at AccessGUDID.

A UDI is a unique numeric or alphanumeric code that consists of two parts:

 a device identifier (DI), a mandatory, fixed portion of a UDI that identifies the labeler and the specific
version or model of a device, and
 a production identifier (PI), a conditional, variable portion of a UDI that identifies one or more of the
following when included on the label of a device:
 the lot or batch number within which a device was manufactured;
 the serial number of a specific device;
 the date a specific device was manufactured;
 the distinct identification code required by §1271.290(c) for a human cell, tissue, or cellular
and tissue-based product (HCT/P) regulated as a device.

Devices that are currently out in the field and manufactured before September 24th, 2016 that are returned for
repair, return to stock, conversion, or otherwise do not need to be relabeled with UDI compliant serial/model
labeling. However, the device packaging will need to be updated to reflect UDI information.

Devices that are manufactured after September 24th, 2016 with a UDI compliant serial/model label and is
converted to R/U from the base part number will not need new UDI serial/model labeling applied. However, a
new UDI number will be assigned to the corresponding R/U part number for the packaging labeling.

Serial/model labels need to be replaced with UDI compliant labeling if the label has become illegible or the
repair part where the serial label is applied requires replacement.

7.6.2 Leak Test
The purpose of the leak test is to confirm that SimplyGo Mini core assemblies have been assembled without
gaps or cracks for gas to leak from.

Per Section 7.5, SimplyGo Mini devices are adequately tested for leakage regardless of the implementation of
a core assembly leak test. However, the core assembly leak test can identify leakage earlier in the service
repair process; and thus, aid in rapid troubleshooting.

This test utilizes the SimplyGo Mini Service Tool software. Refer to the install instructions in Section 3.2.

The PC and the SimplyGo Mini Service Tool communicates with the SimplyGo Mini device to control the core
assembly’s process valves.

NOTE

The argon gas tank, tubes, and tube fixtures are not shown in the recommended test station equipment table
above and should be obtained at the discretion of the test rig preparer (e.g., tubes should be sized to work with
the flow meter of choice, tube fittings should be chosen based on the selected tubes, etc.).
Additionally, ensure that the flowmeter purchased for testing is compatible with your their test set up (e.g.,
configure for Argon gas when using Argon to test for leaks).

7.6.2.2 Test Procedure

 Set up leak test:

TEST SETUP WILL VARY SUBJECT TO PROCURED EQUIPMENT.
o It is recommended to set up the test in the configuration shown in Section 7.6.2, but
there are many variations of the test setup and equipment that could be utilized.
o An example test setup is shown in the Figure below.

Page 149

1112893, Ver. 04

SIMPLYGO MINI SERVICE & TECHNICAL INFORMATION

 Example Test Setup (Tank and Computer not Shown)

o The primary pressure gauge on the argon gas cylinder should always remain above 100
PSI during testing. The secondary pressure gauge should be set to 40 - 60 PSI.
o The precision regulator downstream of the gas cylinder should be collocated with the
test setup and be set to 12 PSI. It should always read approximately 12 PSI during test-
ing.

Example Regulator

Page 150

1112893, Ver. 04

SIMPLYGO MINI SERVICE & TECHNICAL INFORMATION

 o The ball valve should be in the ‘on’ position to allow gas flow to the test setup while test-
ing, otherwise this should be ‘off’.
o The 3-way valve is used to bypass the orifice and flow meter to allow rapid filling of the
core during the initial fill and pressurization step. Once the test setup is pressurized, flow
should be directed to the flow meter for testing.

Example Valves

o The flow protection orifice protects the flow meter from damage that could be caused
from excessive flow.

Example Orifice
o The flow meter measures the mass flow of gas into the core assembly. If the core is as-
sembled correctly, this flow should be approximately zero. An example flow meter is

 shown below, note that the meter stand and cable tie are added for convenience and not
specified.

Example Flow Meter

o A T-connector fitting reconnects the flows paths from the 3-way bypass valve.
o A plug is used to occlude the product tank outlet.

Occluded Product Tank

o The O2 interface kit facilitates communications between the PC and the SimplyGo Mini
device (see COM port procedure and the figure below).

Page 152

1112893, Ver. 04

SIMPLYGO MINI SERVICE & TECHNICAL INFORMATION

 COM port Connected to Disassembled SimplyGo Mini

o The core should be removed from the unit, placed on an electrostatic discharge surface
close enough to the SimplyGo Mini device to plug the process valve connector into the
device.
o The SimplyGo Mini device should have its power brick plugged in.
 COM port procedure:
o The SimplyGo Mini Service Tool consists of a PC running a test application developed in
LabVIEW. The test PC should be configured to have at least one (1) dedicated COM
port to communicate to the SimplyGo Mini device, any available COM port is acceptable.
o The PC’s COM Ports must be configured as follows:

 Process valve verification procedure

1. Connect the SimplyGo Mini Service Tool to the SimplyGo Mini device with the O2 Inter-
face kit.
2. Turn the SimplyGo Mini device ‘on’.
3. While running leak test, do not touch the user interface on the SimplyGo Mini device.
4. Using the SimplyGo Mini Service Tool, open the menu that controls the process valves
(i.e., “Process Valve Control” under the “Functions” menu).

 Process Valve Control Screen Shot
5. Refer to the figure below for the valve configuration.
i. Activate the valve labeled 1 for B side exhaust.
ii. Place finger on the valve to feel or be close enough to the unit to hear the ‘click’
of the valve actuating.
iii. Deactivate the B side exhaust valve.
6. Repeat steps i, ii, and iii above with the valve labeled 2 for B side fill, the valve labeled 3
for A side fill, and the valve labeled 4 for A side exhaust.
7. If any of the valves are not actuating, then the test is deemed a failure. After verifying
that the failure is with the valves (i.e., not a faulty PCA, etc.) either the process valves or
the entire airside manifold should be replaced depending on the availability of parts.

SIMPLYGO MINI SERVICE & TECHNICAL INFORMATION

  Running the test:
1. Open the A & B side fill valves.
2. Ensure that the exhaust valves for the A & B side are closed.
3. Set the bypass valve to the bypass path (i.e., path without the flow meter).
4. Open the gas flow valve to allow the core to pressurize.
5. Allow the core to fill for sixty (60) seconds.
6. Ensure that the precision regulator is still at 12 PSI.
7. Set the fast fill bypass valve to the flow meter path.
8. Let the system stabilize for ten (10) seconds.
9. Record the indicated flow rate of the meter on the “Service Leak Test Data Sheet”.
 The device’s test results records shall be physically and/or electronically stored
in order to satisfy the storage and retention requirements of all applicable regu-
latory bodies.
10. Record the indicated pressure on the “Service Leak Test Data Sheet”.
 If the flow meter has the capability of measuring PSIA and/or PSIG, this data
should be incorporated instead of the pressure regulator.
 If the unit measures PSIA, then take a before and after reading. Subtract the
two readings to get PSIG (e.g., older Alicat flow meters).
 If the unit reads PSIG, then the reading can be used directly (e.g., newer Alicat
flow meters).
11. The recorded flow rate shall be less than or equal to five SCCM (≤5 SCCM).
12. The recorded pressure shall be twelve plus or minus two PSIG (12 ±2 PSIG).
13. If the two recorded measurements are not within the prescribed ranges, then the test is
deemed a fail.
