Appendix B: Reordering Instructions
(For front panels S/N AHT07499 and below)
The VELA series ventilator has had three different platforms since it’s release in 2002.
VELA T-2, VELA CF-1 & VELA CF-2
The major differences between the three platforms is seen in the Front Panels. VELA T-2 used a
modified Main PCB from the T-Bird series ventilators, and a separate video PCB. When we went to
the VELA CF platform we had a new Main PCB that incorporated it’s own Video capabilities with
FiO2 monitoring as well. This was a solid PCB that would allow the ventilator to have external
software downloads with minimal down time waiting for parts to be shipped. Our software updates
and upgrades are obtainable through our Website.
Our first run of Cold Fire processors worked well, but unfortunately certain components used on this
PCB were no longer manufactured in a similar package and so we had to redesign the PCB
completely. During this time also other capabilities were required for the growth of the VELA
Ventilator series and these new features were then introduced into the new design. With the release
of Cold Fire 2 there was a need to change the P/N’s of the Front Panel and the Main PCB’s which is
evident in the Disassembly/reassembly section of this manual.
We have a limited amount of the Cold Fire 1 Front Panels P/N 16345A & J available. When these
are no longer available, kit P/N 82850K Main PCB will replace them. This kit will include the Turbine
EEPROM, as the existing EEPROM on the Cold Fire 1 Turbines are not forward compatible with the
Cold Fire 2 processor.
When ordering the kit the S/N of the ventilator and the turbine will need to be provided. The factory
will then reprogram the new turbine EEPROM with the stored characteristics from the original
turbine file.
