CAIRE Service School Trainings and Webinars 2022
CAIRE offers In-person and Virtual Service Schools covering both LOX and Concentrator lines.
With the easing of travel restrictions due to COVID, CAIRE will be returning to in-person Service Schools
at its Ball Ground location beginning with the November classes. Each class is a comprehensive programthat focuses on the technical and service aspects of the CAIRE family products. Class time is divided
between lecture and hands-on workshops. The seminars will help the student develop a better
understanding of how liquid oxygen equipment or concentrators work, how to identify the symptoms
and causes of potential problems and how to use the technical information that is available in theTechnical Manuals. Registration for CAIRE’s Service Schools is mandatory. Registration forms must be
received two weeks prior to the start of the class in order to guarantee availability and materials.

PRODUCT UPDATESFreeStyle® Comfort® Battery Pack Duration
There are many factors that influence battery run time on FreeStyle Comfort:• Ambient temperature• Ambient pressure• Compressor hours• Device condition• Battery age
FreeStyle Comfort batteries are designed to last 300 charge/discharge cycles: however, battery packs
may perform to specifications past 300 charge/discharge cycles.
Note: If the unit is not in use, it is recommended to remove the battery from the unit when notconnected to a power source to maximize the battery duration when needed.
For more details on battery pack duration test, please refer to Service Bulletin 21494318

End of Service Life for G3 Meters, Harnesses and ManifoldsIn June 2006, CAIRE released the G4 liquid level gauge, harness, manifold assembly, and otheraccessories. At that time production of the G3 liquid level gauges, harnesses, and manifolds wasdiscontinued. However, customers were still able to purchase G3 parts and accessories until the existing
stock was depleted. As of January 2008, CAIRE no longer supplies G3 liquid level gauges or its
components, including the decal plate, harnesses, and manifolds; therefore, G4 parts must be ordered.
G4 liquid level gauges display the liquid level via LEDs arranged in a semi-circle. Additionally, a smaller
battery is in the meter housing and is rated at 5 years with 30 actuations/day.
Please refer to Service Bulletin 13938524 for G3 retrofit kit part numbers.

wait 5 seconds before attempting the sequence again. Patients should notbreath off the device while it is in test mode.
5. Once in test mode the flow can be increased or decreased as usual. Thebattery duration test can be done at any flow setting.
6. While in test mode the unit will pulse at a pre-programmed frequency of 20
breaths per minute.
7. Using a stopwatch or timer, record the time it takes for the FreeStyle
Comfort to completely shut down.
8. Take this time recorded and compare it to the full capacity operating time ofa new battery pack in the table below. If this time is less than 50% of the fullcapacity of a new battery pack, it is recommended that the battery pack betaken out of service. See table 1 below:

The G4 harness features a low-temperature PVC insulated wire and an
externally threaded feed-through nut, see Figure 3.
