Installation Instructions
*Marus recommends installation to be performed by a qualified technician.
1. After the required support structure is in place, remove the track from its shipping container. Remove
the plastic end cap from each end of the track, remove the transformer cover and remove the side trim
panels. The side trim panels are removed by pulling the straight outward after the end caps are removed.
(See figure below).
2. Use 5/16” lag bolts (not included) of a length that will penetrate at least 3/4” into solid wood to attach the
pallet to the ceiling or support structure. Holes can be drilled and countersunk in other locations along the
edges of the pallet, if required, to align with existing ceiling joists or support structure. Be sure that the
heads of the lag bolts do extend past the surface of the pallet. The side trim extrusions will not fit
unless the heads are flush.
CAUTION: The ceiling or support structure and hardware used must be capable of supporting 200 lbs. dead
weight.
3. Ascertain that the power to the track light circuit is off and make
the necessary electrical connections. We recommend that a
licensed electrician make the required power connections.
4. Assemble the post to the trolley. To do so, remove the electrical
bracket and insert the post into the trolley, slide the coiled power
cable into the post and insert the cross pin. After being certain
that the cross pin is resting fully in its groove, re-install the electrical bracket. Finally, tighten the two socket head set screws to
hold the post firmly in place. (See figure at right).

Installation continued...
6. Remove the two trolley stops from the track by
pulling off the plastic cover and turning the stop
stud counter-clockwise until it unscrews from the
track. Slide the trolley onto the track being sure
that the wheels that are concave align with the
raised side of the track.
7. Plug the power cable into the trolley electrical
bracket being certain that the cord is curved
behind the trolley. (See figure at right).
8. Roll the trolley to approximately the center of the
track and re-install the stop studs removed in
step #6. Don’t forget to replace the plastic caps
onto the studs.
9. At this point, roll the trolley back and forth on the track several times to check for freedom of movement.
Also check that the trolley stays in place and does not drift to one end of the track. If the trolley tends to
drift toward one end of the track, place spacers between the opposite end of the track and the ceiling or
support structure to level the track. Recheck and add spacers as required until the track is level and the
trolley will remain stationary.
CAUTION: When adding or removing spacers, take steps to secure the trolley in place on the track. Wedge a piece of cardboard
between the wheels and the track to keep the trolley in place.
10. Re-install the side trim extrusions, transformer cover, and end caps
removed in step #1.
11. Place the locking tab retaining collar on the post just above the
locking tab slot and lightly tighten the set screw. CAUTION:
OVERTIGHTENING THE SETSCREW WILL MAR THE PAINTED
SURFACE. Install the stop screw in the light adapter according to
whether the operator is right or left handed.
12. Grease the light adapter and the inside of the bottom of the post.
Have an assistant hold the light assembly with the adapter near the
bottom of the post. Plug the short male cord into the female coiled
cord firmly being certain that this plug makes a tight connection so
as not to become disconnected in the future. (See figure at right).
13. Slide the light adapter into the bottom of the post until it bottoms.
Look into the slot to be sure the stop screw is not within the confines of the slot. Now place the locking tab into the slot in the side
of the post. The locking tab fits flush into the ceiling post. Now
loosen the setscrew and the locking tab retaining collar and lower it
over the slot. Align the collar with the bottom of the post and tighten
the setscrew firmly. The assistant supporting the light can now
release it. (See figure at right).

Installation continued...
14. Remove the reflector shield by turning the bulb shield counter-clockwise and pulling the bulb shield
straight out. (See figure below). Peel the protective plastic film from the reflector shield and reassemble.
NOTE: Make sure the bulb shield locks into place. The Marus logo should be straight and level. Gently
pull out on the bulb shield to ensure that it is locked in place.
*NOTE: If bulb or reflector has been touched, they MUST be wiped clean using denatured alcohol before being put into operation.
15. Turn on power switch and check the light for proper operation at high, medium, and low. The light is factory preset for a 27” focal distance. This focal distance can be varied to suit the operator. See the included
operator’s manual for details. This completes the installation and testing of the track light.

Controls
On/Off Switch
The on-off switch is located on the control panel directly above the light reflector. The long toggle provides
easy, one motion movement to “flick” the light on or off. When the toggle is in the up position, the light is
on; the down position turns the light off.
Intensity Switch
A 3-position, rocker-type switch is located adjacent to the on-off switch on the control panel. Depressing
the upper portion of the switch places the intensity control in the “HIGH” position allowing the light to emit
its maximum brilliance. An intermediate or “MEDIUM” intensity is obtained by placing the switch in the inbetween position and the lowest intensity by depressing the lower portion of the switch.
Spare Bulb
12
The Marus light is equipped with a spare bulb located in the rear of the light head. If the bulb should happen to fail, replace with spare bulb provided. See bulb replacement page 13.

Bulb Removal and Replacement
NOTE: For maximum reliability and optimum operation, always use Marus Replacement Bulb No. 014R207.
The use of after-market bulbs can cause damage to the bulb socket.
WARNING!!
DO NOT ATTEMPT TO REMOVE THE BULB FOR 2 MINUTES AFTER THE
LIGHT HAS BEEN TURNED OFF OR UNTIL THE BULB HAS COOLED.
To Remove Bulb
The bulb shield is secured by a twist-lock. To remove the shield, twist counterclockwise and pull straight outward until it clears the bulb and reflector shield and let hang on the tether out of the way; then lift off the cover.
The bulb is a two-prong push-in type with one prong larger than the other to prevent improper installation. To
remove the bulb, grasp the base of the bulb and pull straight outward; a slight side-to-side rocking motion will
work the bulb loose.
Always grasp the bulb by the base when inserting. Do not touch bulb or
reflector. If the bulb or reflector has been handled or touched, they MUST
be wiped clean with denatured alcohol before being put into operation.

Cleaning the Light
The 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.
If you use an iodophor, it is especially important that you follow up with an iodophor neutralizer.
IMPORTANT: Do not use powdered cleansers, scouring pads or abrasive scrubbers on any of the
painted, plastic or metal surfaces of this light. To remove dried-on material, use a soft bristled brush
and a solution of mild detergent.
WARNINGS, DISINFECTING & STERILIZATION - LIGHTS
Infection control in the dental office 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:
equipment. Wherever possible disposable barriers should be
used and changed between patients. The barrier technique
will ensure maximum long term durability of the surfaces and
finishes of the equipment.
Infection Control
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 manufacturer’s disinfectant 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.
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
The Manufacturer strongly advocates the barrier technique be used
whenever possible to preserve the finish and appearance of the

CLEANING YOUR UPDATED PROJECT FILE ATTACHED IN PDF
Cleaning Reflector and Cover
NOTE: Use only denatured alcohol to clean the glass reflector. Use only mild soap and water to clean
the plastic reflector cover.
Do not use any solvents, abrasives, abrasive cloths or cleaners,
as they may damage the coated surface of the reflector.
Be sure the electrical supply is turned off and the light is cool before attempting any cleaning or polishing.
Remove the bulb shield, cover and bulb for full access to the reflector. (See “Bulb Replacement” for bulb
removal).
Use a clean, soft** facial tissue dampened with denatured alcohol and gently wipe the surface of the reflector and the bulb. The plastic reflector cover may be gently washed with soap and water and dried using a soft
towel.
Cleaning Painted Surfaces
The painted surfaces of your light can be cleaned by simply wiping with a damp cloth. No other protective
coating is required to preserve the permanent luster of the painted surface.
CAUTION: Placing aluminum foil over the lamp handles for barrier asepsis will cause permanent discoloration of the handles. We recommend covers specifically manufactured for this purpose. Discoloration of the
handles caused by the above is not covered under warranty.
**We recommend Puffs facial tissues.
NOTE: The plastic reflector cover must always be in place when light is used because it will
catch bulb particles in the rare event a bulb should break; also, it will keep abrasive material
away from the coated surface of the reflector.

Introduction
Principle of Operation/Overview
The LuxStar light was designed from the outset to be
easily and quickly serviced with a minimum of downtime.
With this manual and basic tools the light can be serviced
by anyone with a basic understanding of electricity and
mechanics.
The LuxStar light utilizes a multi-tap transformer which
reduces and converts the AC line voltage to three AC
voltages which are supplied to the three-position intensity
switch. The selected voltage is then routed through the
single pole on/off switch and then to the lamp. The lamp
is a halogen-filled quartz lamp with a polarized bi-pin
plug in the base. The light produced by the lamp is
reflected and color corrected by the dichroic coating on
the inside surface of the reflector. The dichroic coating
provides a correlated color temperature of 4500 degrees
Kelvin at the medium intensity setting. The light also
incorporates a self-resetting thermal switch in the
transformer and a fuse incorporated in the ceramic lamp
base for electrical safety.
Recommended Tool List
In addition to basic hand tools the following tools are
required when troubleshooting and repairing the light:
• Volt-Ohm meter — used to measure voltage
and resistance.
• Complete assortment of hex wrenches.

PROBLEM
CAUSE
Lamp will not light. Burnt out lamp.
TEST/SOLUTION
Replace lamp. The lamp can be tested with an ohm meter to confirm its failure. A
good lamp should indicate approximately 2 ohms resistance. A failed lamp will have
infinite resistance.
No power to
light.
Confirm that the circuit the light is powered by is live. Confirm that light has not
become unplugged inside the post.
Defective on/off
switch.
Check the on/off switch with an ohm meter. A good switch should indicate
approximately 0 ohms resistance when on and infinity when off.
Defective lamp
socket.
Check the pins of the lamp for evidence of arcing or burning. The pins should be clean
and shiny. If arcing or burning is present, replace both the lamp and the socket.
Defective lamp
socket wire.
Check the two gray Teflon insulated wires in the light yoke for continuity. Check
between the socket and where the gray wire attaches to the on/off switch. The other
gray wire attaches to the white wire from the arm cable. If one or both wires are open,
replace the socket and wires as an assembly.
Defective
intensity switch.
Remove the lamp from its socket and inser t voltmeter leads. The voltmeter should be
set to measure 25 volts AC. Turn the on/off switch on. The following voltages should
be present at these settings:
High:
19 volts AC
Medium: 17 volts AC
Low:
15 volts AC
If one or all of the above voltages are not present, proceed to the next step. If all of the
above voltages are present, review the preceding steps.
Remove the rear housing cover and check for the following voltages at the rear of the
intensity switch.
Black and White wires:
19 volts AC
Green and White wires: 17 volts AC
Red and White wires:
15 volts AC
If all the above voltages are available at the back of the intensity switch, the intensity
switch is defective and must be replaced. If one or all of the voltages are not present,
proceed to the next step.
Defective arm
cable.
**CAUTION: HIGH VOLTAGE**
If one or more of the voltages in the step above is not present, remove the transformer
cover and check for their presence at the secondar y outputs of the transformer. See
the wiring diagram for details. If one or more of the voltages is not present at the back
of the intensity switch but is present at the transformer, the arm cable is defective and
must be replaced. If the voltage(s) is not present at the transformer, proceed to the
next step.
Defective
transformer.
**CAUTION: HIGH VOLTAGE**
Confirm 115 volts AC is supplied to the primar y of the transformer. Check at the
terminals of the transformer secondar y for the following voltages:
Terminals C-1 and 1: 15 volts AC
Terminals C-1 and 2: 17 volts AC
Terminals C-1 and 3: 19 volts AC
If any or all of the voltages listed above are not present, the transformer is defective
and must be replaced.
Light cannot be
turned off.
