Routine Care
Clean plastic and upholstery surfaces iegularly using a mild soap and water solution.
When cleaning, use a dampened cloth only, as excess cleaning solution can flow into the chair and cause perma-
nent damage to electrical components.
Barrier Technique
Use of disposable barrier products should be the first choice for the protection of dental equipment. Disinfectants
leave behind a surface residue that accumulates over time and eventually damages equipment and upholstery
surfaces.
Chemical Disinfection
If a chemical disinfectant is to be used on chair or upholstery surfaces, contact the manufacturer of the disinfec-
tant prior to use.
Obtain verification from the disinfectant manufacturer that their product will not damage the chair or upholstery
surfaces.
Unacceptable Disinfectants
The following chemicals may damage equipment and upholstery:
* Alcohol based solutions
* Bleach
* Phenol / Alcohol combinations
* Foam spray products
* Benzalconium chloride solutions
Use with Caution
* Water based phenolic disinfectants, following manufacturer’s exact instructions for use.
Do not spray liquids directly onto chair surfaces.
In order to prevent damage to electrical components and systems, do not apply excess cleaning solution
onto chair surfaces.
Warranty does not cover damage to equipment and upholstery caused by disinfectant solutions.
