Example of an deflated middle cell section.
The controller is only able to detect defective inner cells according
to chapter 6.3. The defective upper cells must be identified by the
user according to the instructions stated in chapter 7.2.3.
If you notice any damaged components or surfaces, contact Carital
®
service.
7.2.4 Life cycle of the mattress system
The estimated life cycle of the mattress system, when properly cleaned and maintained
under its normal intended purpose, has been assessed to be as follows:
• Controller and hanger: eight (8) years
• Cells and tube system: six (6) years
• Covers: five (5) years
If the mattress is used in violation of the instructions specified in
the user’s guide, or it is not cleaned of body secretions containing
urea in particular, or the mattress system is used by a prominently
sweating or mobile patient weighing over 200 kg, the estimated life
cycle of the cover and the cells may be shortened.

ler and the replacement of wearing parts.
