Section I Introduction
Safety Precautions
• 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.
CAUTION
• Wiring schematics are provided with this
manual.
• Isolating the unit from the supply mains is
accomplished by unplugging the unit from
the power receptacle.
NOTICE
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.
• Do not modify the NuSimplicity 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
• Evidence that the safety certication
of the ACCESSORY has been
performed in accordance to the
appropriate IEC 60601-1 harmonized
standard.
• The plug cannot be located in a position
that requires tools to access.
• 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.

Air Glide (Optional)
NOTE: If the air glide option was ordered,
the air regulator was attached to the base
chassis prior to shipment of the chair.
1. Place the NuSimplicity Chair on a smooth, hard
and level (vinyl, tile or terrazzo type) oor.
2. Connect the air glide tubing to a regulated air
supply source (usually 552 kPa [80 PSI] on
most dental units) (Figure 15).
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 can not seal to
the oor. Slowly decrease the pressure until
the chair stops bouncing.
4. Actuate the air regulator toggle switch
(Figure 16) at the rear of the chair on the base
cantilever section cover.
