WARNING Before proceeding with electrical installation, all wiring must be in accordance with NEC and
local electrical codes.
To avoid the risk of electrical shock, this equipment must only be connected to a supply mains
with protective earth.
The plug cannot be located in a position that requires tools to access.
Do not modify the chair without permission from DENTALEZ.
The use of ACCESSORY equipment not complying with the equivalent safety requirements
of this equipment may lead to a reduced level of safety of the resulting system. Consideration
relating to the choice shall include:
use of the accessory in the PATIENT VICINITY and
evidence that the safety certification of the ACCESSORY has been performed in
accordance to the appropriate IEC 60601-1 harmonized standard.
To prevent injury from falling or crush hazards, patients should be seated upright in the chair
facing forward. Their head should be on the headrest with their feet at the toe of the chair. Their
arms should be on the armrests or folded across their midsection.
Headrest options that contain magnets can interfere with the function of some medical devices,
including pacemakers.
SECTION I - INTRODUCTION
CAUTION Before attempting to move the chair, it must be lowered to its lowest position and locked in place
at zero degrees rotation. It is strongly recommended that accessories, such as lights and units,
be removed before moving.
Rating of main circuit breakers should be 20 Amps maximum.
To satisfy FCC RF exposure requirements for mobile and base station transmission devices,
a separation distance of 20 cm or more should be maintained between the antenna of this
device and persons during the operation. To ensure compliance, operation at closer that this
distance is not recommended. The antenna(s) used for this transmitter must not be co-located
or operating in conjunction with any other antenna or transmitter.
NOTICE Medical electrical equipment needs special precautions regarding electromagnetic
(EMC) compatibility and needs to be installed according to EMC information. (See EMC
INFORMATION provided in this manual.)
In accordance with Part 15 of FCC rules, this equipment was tested and complies with Class A
digital device limits. These limits are designed to give equipment reasonable protection against
detrimental interference when operated in a commercial environment.
Mobile radio frequency (RF) communications equipment can affect medical electrical
equipment.
Wiring schematics are provided with this manual.
Isolating the unit from the supply mains is accomplished by unplugging the unit from the power
receptacle.

SAFETY PRECAUTIONS (CONTINUED)
SECTION I - INTRODUCTION
NOTICE This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy, and if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications; however, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception (which can be determined by turning the equipment off
and on) the user is encouraged to try to correct the interference by one or more of the following
measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment to an outlet on a circuit different from that to which the receiver is
connected.
Consult the dealer or an experienced radio/TV technician for help.

WARNING To prevent injury as a result of chair tipping, chair must be placed on a smooth, hard and level
floor.
DO NOT position the chair any place where it would interfere with unplugging the chair power
cord.
Before mounting a delivery unit, it is recommended to anchor the chair to the floor for optimal
stability (FIGURE 5).
1. Taking into consideration the chair’s dimensions, range of motion, and specifications (see SECTION I -
INTRODUCTION), position the chair in its permanent location on a smooth, hard and level floor.
NOTE: Make sure the chair is placed where nothing will interfere with its movement.
2. Remove the retaining strap that secured the base mechanism during shipment.NOTE: The base cover must be

1. Place the chair on a smooth, hard and level (vinyl, tile or terrazzo type) floor.
2. Connect the air glide tubing to a regulated air supply source (usually 552 kPa [80 PSI] on most dental units)
(FIGURE 6).
3. The air glide is pre-set at the factory to 138 kPa (20 PSI). Because of additional optional equipment, it may be
necessary to increase the pressure. Slowly increase the air pressure by adjusting the air regulator on the base
chassis until the chair begins to “bounce”. This is an indication that the air pillow is over-pressurized and cannot
seal to the floor. Slowly decrease the pressure until the chair stops bouncing.
4. Actuate the air regulator toggle switch at the rear of the chair on the base cantilever section cover (FIGURE 7).
5. Check for proper air glide operation.
6. Make sure the doctor and staff receive proper air glide feature operation instructions (see SECTION IV -
OPERATION - AIR GLIDE).
