REGULATORY INFORMATION
Technical Description
The dental chair is used to position the patient so that the oral cavity is in the desired position for the dentist to
perform various dental procedures. Dental chairs can be either hydraulically or electromechanically operated.
There are two dynamic functions: the base (up/down) and the back (forward/back). These functions are
activated by use of either a foot switch or a hand-operated touch pad.
The dental chairs have the provision to mount additional dental equipment including over-the-patient delivery
systems. For this purpose the chair must provide a stable foundation for both the patient and the additional
equipment.
Power to the chair is either 115 or 230 volts. The power is delivered to a microprocessor controlled printed circuit
board. Software in the microprocessor controls the movement of the chair. The dentist can program some chair
models to preset positions.
Device Classication
The dental chair is classied as Class 1 device under rule FDA CFR 21, Class I device
under Health Canada guidelines, and a Class I device under rule 11 of the MDD 93/42/
EEC of Annex IX.
Safety and Identication Markings
This dental chair can be identied by its product label, located inside or underneath the chair seat. This label
states the chair model and serial number, electrical specications, manufacture date and safety classication.

WARNING: *The Manufacturer makes no
representation as to the disinfectant efcacy
of these products. We make no warranty
expressed or implied that these disinfectants
will not damage the surface nishes. Damage
and discoloration of the surface nishes are
not covered under the warranty.

CLEANING, DISINFECTING & STERILIZATION
IMPORTANT: Do not use powdered cleansers, scouring pads or abrasive scrubbers on any of
the painted, plastic or metal surfaces of this dental unit. To remove dried-on material, use a soft-
bristled brush and a solution of mild detergent.
Equipment can be cleaned with a solution of mild detergent and warm water. A variety of surface disinfectants are
available for use in dental treatment rooms. Some of these can cause discoloration of painted, plated or anodized
surfaces with repeated use. This can be minimized by careful adherence to the disinfectant manufacturer’s
instructions and by frequent washing with soap and water.
The Manufacturer strongly advocates the barrier
technique be used whenever possible to preserve
the nish and appearance of the equipment. Wher-
ever possible disposable barriers should be used
and changed between patients. The barrier tech-
nique will ensure maximum long term durability of
the surfaces and nishes of the equipment.
Unacceptable Disinfectants Conditionally Acceptable Disinfectants*
These disinfectants will harm the surface nishes of
dental equipment and are not recommended. Use of
these products will void your warranty.
These disinfectants have been found to be the
least harmful to the equipment surfaces by our test
methods.
Disinfection & Sterilization
Infection Control in the dental ofce continues to
be a high priority for our customers and end users.
OSHA, the ADA and the CDC are also involved in this
complex issue. The Manufacturer will not attempt to
specify the required intervals for disinfection nor can
it recommend the overall best surface disinfectant.
Please refer to the Infection Control Recommendations
published by the American Dental Association for further
information. The question is often asked, “What should
I use to disinfect my dental unit, chair and light?” This
question is more complex than it seems because of
the wide variety of products on the market as well as
formulations of the products changing to meet the
needs of increased asepsis.
Barrier Technique
Chemical Disinfection
Regardless of the chemical disinfectant used, it
is imperative that the equipment be thoroughly
washed with mild soap and warm water at least
once per day. This wash-down will minimize the
harmful effects of chemical disinfectant residues
being allowed to accumulate on the equipment.
When using chemical disinfectants, always pay
strict attention to the disinfectant manufacturer’s
directions. When using concentrated disinfectants,
measure the concentrate carefully and mix
according to package directions. Disinfectant
solutions that are relatively harmless to surfaces at
their recommended strengths can be corrosive at
higher than recommended dilution ratios.
WARNING: Disinfect only by wiping,
no spray disinfection. Please be
aware that the manufacturer expressly
rejects any claims for warranty or
damages when using other cleaning
and disinfection solutions.
**Iodophor-based disinfectants will cause yellow staining on many surfaces.

CLEANING UPHOLSTERY*
While staining and soiling exposures are common to upholstery fabrics, most may be removed by using
the following cleaning methods.
Light Soiling
• Use a solution of 10% household liquid dish soap with warm water and apply with a soft, damp
cloth. Be sure to rinse away any remaining solution from the chair’s surface.
• If stubborn dirt remains as a stain embedded in the grain of the vinyl use a soft brush, and if
necessary, a touch of cleaning powder or other household cleanser. In both situations, rinse and
dry with a soft cloth.
Heavy Soiling
• Dampen a soft, white cloth with naphtha (lighter uid) or rubbing alcohol and rub gently. Rinse
with a water dampened cloth to remove any remaining concentration.
Other Tips
• To clean stained or soiled areas, a soft white cloth is recommended. Avoid use of paper towels.
• To restore luster, a light coat of spray furniture wax may be used. Apply for 30 seconds and follow
with a light bufng using a clean, white cloth.
• When using strong cleaning agents such as rubbing alcohol or bleach, it is advisable to rst test in
an inconspicuous area to determine potential damage to the material.
• Never use harsh solvents or cleaners which are intended for industrial application.
