1.0 User Information
Intended Use
The Nuvo Surgical Light is intended to provide a field of illumination in surgical,
diagnosis or treatment applications. The single light head configuration is intended for
minor surgical, diagnosis, and/or treatment applications and may be used in the situation
where the treatment or procedure can be interrupted. The dual and triple light head
configurations may be used in operating rooms for all surgical applications and where a
fail safe condition is required; alternatively, two singles, or a dual plus a single, are often
installed.
Introduction
This manual provides the information required for normal operation of the Nuvo Surgical
Light from Nuvo. Before operating the Nuvo Surgical Light, be sure that you have read
and understood in detail the contents of this manual. It is important that you read and
strictly adhere to the aspects of safety contained in this manual.
Product Overview

Positioning
The Nuvo Surgical Light provides the surgeon with a suspension system that is perfectly
balanced and can be guided effortlessly into any position.
The upper and lower suspension arms can rotate continuously around the ceiling mount.
The longer upper arm allows both arms to be positioned independently without
interfering with one another.
The counterbalance arms also rotate continuously around their vertical extensions. These
extension pieces are custom sized according to the ceiling height, assuring adequate head
clearance.
The yoke assembly, which holds the light head, turns continuously around the end of the
counterbalance arm. The light head pivots 320° inside the arms of the yoke.
The combination of these individual elements allows medical personnel to move the light
freely into an infinite variety of positions using only slight pressure on the Sterile Handle
Control. Once positioned, the system remains stable, without drifting, allowing focus to
remain where it belongs...on the patient.

Illumination Performance
• The Sterile Handle Control gives the user full command of the Nuvo Surgical Light.
Positioning, intensity, and pattern size can all be easily controlled from inside the sterile
field. A second set of intensity controls is conveniently located on a wall mounted panel.
• The Nuvo Surgical Light’s compact, 23" (58.4 cm) diameter light head combination
provides color-correct, shadow free illumination well suited to a wide variety of
procedures.
• The perfectly-honed inner reflective surface of the light head features 1890 reflective
facets computer designed for maximum light intensity and shadow reduction.
• With the generation of so many individual light rays, a large percentage of the projected
light can be blocked before any shadow is evident.
• Deep cavity illumination negates the need to refocus midway through a procedure. The
minimum depth of field, without refocusing, is 20" (50.8 cm).
• Each light head delivers 137,000 lux (12700 foot candles) and the color temperature of
the lamp has been optimized at 4300°K to ensure the color clarity of the surgical site.
• The use of a custom designed IR filter reduces emitted IR to a 3.8 μW/cm2fc average.
This low heat output ensures maximum comfort during long procedures.

Easy Maintenance Features
Backup Lighting and Bulb Replacement
To assure that the Nuvo Surgical Light will offer peak performance on demand, each
Light head is equipped with two bulbs. In the event that the primary bulb burns out
during normal operation, the backup will take over immediately. The changeover
happens so quickly that it is transparent to the user.
The quartz tungsten-halogen bulbs employed in the lamp provide as many as 1000 hours
of uninterrupted light before they need to be replaced. Spare bulbs are conveniently
housed in the wall control box. When necessary, fast, simple bulb replacement can be
accomplished in minutes between cases and without the need for special tools.
Cleaning and Sterilization
Special attention has been given to the aesthetics of the Nuvo Surgical Light. The
smooth, clean lines are visually appealing and aid in the prevention of dust particle buildup. Enhanced streamlining greatly reduces air turbulence over the surgical field.
The Sterile Handle Control is compatible with a wide range of sterile covers. It can also
be easily removed for steam sterilization or cold sterilization.

Instructions for Use
WARNING:
Do not operate the light if the glass filter is broken or removed. Operation without
the glass filter or with a broken glass filter could cause high levels of ultraviolet
and infrared radiation resulting in injury to the patient or user.
To identify a broken glass filter, inspect for the following:
1. Changes in the light pattern.
2. Loose particles under the lens.
3. Rattling noise when moving the light.
WARNING:
Not for use in areas of explosion hazard. This apparatus is neither approved nor
certified for use in areas where combustible or explosive gas mixtures are likely
to occur.
The light can be turned on or off by the use of the push button located at the center of the
sterilizable handle, or by the push button mounted on the wall control unit (both operate
in the same order). The push button on the sterilizable handle overrides the wall control
unit, thereby enabling medical personnel to operate the light in the general vicinity of the
sterile area.
The push button turns the light ON/OFF, and also controls the intensity level of the light.
When the light is turned on, LED’s located on the side of the sterile handle collar, and on
the wall control, illuminates to indicate the intensity level.
SIM-S2Z0001 Rev 05 Effective Date 10/25/09

To Turn ON:
Push the button in once, and release. The blue LED’s located on the side of the handle
collar, and on the wall control, illuminate to indicate the intensity level.
NOTE:
After a power outage, the light automatically comes on at the intensity level that it was at
when the power was disconnected.
To Decrease/Increase Brightness Intensity:
Push the button in once, and release. Each time the button is pushed, the level of intensity
is decreased, until only one blue LED is illuminated. The brightness intensity goes back
to full intensity if the button is pushed and released again.
NOTE:
If the button is depressed and held for three seconds, the light goes off.

2.1 Check the Ceiling Structure
Ceiling Bearing Strength
The medical facility is required to supply a ceiling structure that is capable of sustaining the load
requirements for the contractor installed lighting system. To accomplish this, it may be necessary to
contract with an architect and certify that the Nuvo Surgical Light can be installed safely. The
following table shows calculated worst case load conditions for mounting single, dual, and triple
lighthead configurations. Worst case is defined as having all arm, monitor, and lighthead assemblies on
the same side of the ceiling plate with the lightheads fully extended from the ceiling plate. Improper
installation could result in personal injury or equipment damage. The contractor-installed ceiling
structure and mounting studs must be capable of supporting the following moment loads and vertical
weights (see figure 2.1.1and table 2.1.1):

Ceiling control / Transformer Box
Monitor Controls
Light Control
Camera Control
Select a suitable location to mount the Ceiling Control Box (if not installed previously) within 50 feet
(15.24 meters) of the Nuvo Surgical Light. The selected location should provide room for a technician
to be able to remove the cover and access the voltage adjustment.
Typical locations include:
above the ceiling next to an access panel,
above the ceiling next to a removable lighting fixture,
above the ceiling of an adjacent hallway with removable panels,
in an electrical cabinet on the wall either inside or adjacent to the OR
The control box for single and dual lights measures 8½"(22 cm) x 16"(41 cm), and for a triple light
8½"(22 cm) x 21 ¼(54 cm). Sufficient room above the box is required to remove the cover and adjust
the voltage. A total height of at least 18" is preferred.
If the ceiling control / transformer box is to be located more than 4’ (four feet) from the mounted light
hub, an extension cable must be ordered. These extension cables are available in 6’, 12’, 18’, 25’ and
48’ lengths.
Wall Control Box
The wall control box measures 10" x 10 1/2"(25.4 cm x 26.7 cm) square and is 1 3/4"(4.4 cm) deep. It
connects to a standard two gang 4"(10.2 cm) x 4"(10.2 cm) back box recessed into the wall at
approximately 60” from the floor. A location where this control will be readily accessible to the
circulating nurse should be selected. The wiring harness (35′ 10.67 meters Standard), (50′ 15.24 meters
optional) is then routed from the wall box to the ceiling control box.
Single, dual, or triple light configurations can be operated from a single wall control box. The wall
control contains a discrete set of controls for each lighthead in the configuration. Each is numbered to
correspond to the labels on the suspension arms.

The suspension system may have the vertical tubes pre-installed at the Nuvo factory, if this is the case
then this section does not apply.
1. Remove the vertical tubes (B) from the shipping container, and all of the parts included with the
vertical tube kit box (see figure 2.4.1).
Figure 2.4.1. Vertical Tube Installation
2. Ensure that the vertical tubes (B) you are installing are the proper length for the
Nuvo Surgical Light installation that you are performing (see table 2.4.1).
NOTE:
The longest vertical tube should be installed on the suspension arm assembly closest to the ceiling. The
shorter vertical tube should be installed on the suspension arm assembly closest to the floor.

Vertical Tube Installation
3. Test fit the threads on each vertical tube (B) by temporarily screwing it onto the appropriate
suspension arm assembly (A).
NOTE:
The threads may need to be cleaned if the vertical tubes do not screw onto the suspension arm
assemblies smoothly, and without any binding.
4. Ensure that the wiring (AH) extending from the suspension arm assemblies (A) is long enough
to go through the vertical tube (B), and extend slightly out of the end of the vertical tube (B)
when it is screwed onto the suspension arm assembly (A) all of the way.
5. Screw the vertical tube (B) onto the suspension arm assembly (A) until it bottoms out.
6. Unscrew and back-off the vertical tube (B) until the hole (AI) in the vertical tube (B) lines up
with the threaded hole in the suspension arm assembly (A).
NOTE:
This procedure should give you approximately 1/32” (0.8mm) of clearance between the rotating tube
and the stationary portion of the arm.
7. Test the rotation of the suspension arm assemblies (A), and ensure the arm moves smoothly
without any binding.
