LOX Label Service Kits
CAIRE has created symbolic labels for all LOX reservoirs and portable units. Prior to this change, CAIREmaintained a large variety of LOX labels in stock due to the number of different languages throughout
our markets. The use of symbolic labels on LOX reservoirs and portables will greatly reduce the numberof labels that are currently required.
In Europe, when replacing labelling on any CAIRE medical device, it is a regulatory requirement that thenumber of the notified body who authorized the medical device at the time of manufacture not bemodified. In order to assist our European customers, CAIRE Inc. has created service kits for each unit
type. The service kits are specific to the appropriate CE markings that are required for each unit.
The CE requirements are based on the model and the age of the device. The European kits will include asymbolic warning label, a reference guide for the symbols, and a replacement CE label.
U.S. customers are not required to maintain CE labelling on LOX reservoirs and portables.
Because of this, CAIRE has created separate U.S. label service kits that only include the symbolic warninglabel and a reference guide for the symbols.
Please refer to Service Bulletin PN 21174579.

ISSUE:

LOX label service kits

NOTES:CAIRE has created new symbolic labels for all LOX reservoirs andportable units. Prior to this change, CAIRE maintained a large variety ofLOX labels in stock due to the number of different languages throughout
our markets. The use of symbolic labels on LOX reservoirs and portables
will greatly reduce the number of labels that are currently required. InEurope, when replacing labelling on any CAIRE medical device, it is aregulatory requirement that the number of the notified body whoauthorized the medical device at the time of manufacture not be modified.
In order to assist our European customers, CAIRE Inc. has created service
kits for each unit type. The service kits are specific to the appropriate CE
markings that are required for each unit.
The CE requirements are based on the model and the age of the device.
The European kits will include a symbolic warning label, a reference
guide for the symbols, and a replacement CE label. U.S. customers are
not required to maintain CE labeling on LOX reservoirs and portables.
Because of this, CAIRE has created separate U.S. label service kits that
only include the symbolic warning label and a reference guide for thesymbols.
The tables below detail the applicable service kits for reservoirs andportable units. European customers can determine the age of manufacture
by referencing each unit’s serial number. Diagrams are also provided
below that show the location where each label in the kit should be applied.
