The 115VAC/230VAC service line for
the track light should be evaluated
and installed by a licensed electri-
cian in accordance with local electri-
cal codes.
We recommend that a wall switch be
installed in the power supply to fa-
cilitate servicing and protect the light
transformer in the event of power
surges while the light is not in use
(i.e., electrical storms).
Electrical Requirements
*We recommend installation to be
performed by a qualied 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 straight
outward after the end caps are
removed. (See gure below).
2. Use 5/16” lag bolts (not in-
cluded) of a length that will
penetrate at least 3/4” into
solid wood to attach the pallet
to the ceiling or support struc-
ture. 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 struc-
ture. Be sure that the heads
of the lag bolts do extend
past the surface of the pallet.
The side trim extrusions will
not t unless the heads are
ush.
CAUTION: The ceiling or support structure and hard-
ware used must be capable of supporting 200 lbs. dead
weight.
Installation Instructions

11
3. Be sure 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 rmly in place.
(See gure at right).
5. Prior to installing the trolley onto the track, take a
few minutes to clean any debris from the track rails
that may be present from installing the track on the
ceiling.

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 gure 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 se-
cure the trolley in place on the track. Wedge a piece of cardboard
between the wheels and the track to keep the trolley in place.

Installation Instructions - continued...
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.
16. This completes the installation of the TL 500 Track Light Assembly. Turn on the light and check for proper
operation and balance. The light head is fully assembled and functionally tested prior to leaving the fac-
tory. Should adjustments need to be made, please refer to the Adjustments section of this manual.

WARNINGS, DISINFECTING & STERILIZATION - LIGHTS
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
The Manufacturer strongly advocates the barrier technique
be used whenever possible to preserve the nish and
appearance of 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 nishes of the equipment.
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 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.
Only disinfect by wiping, no spray disinfection.
Please be aware that the manufacturer expressly
rejects any claims for warranty or damages when
using other cleaning and disinfections solutions.
*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.
**Iodophor-based disinfectants will cause yellow
staining on many surfaces.
Unacceptable Disinfectants
These disinfectants will harm the surface nishes of
dental equipment and are not recommended. Use
of these products will void your warranty.
Conditionally Acceptable Disinfectants*
These disinfectants have been found to be the
least harmful to the equipment surfaces by our test
methods.
Chemical Composition
Strong Phenols/Phenol Alcohol combinations
Sodium Hypochlorite/Household Bleach
Sodium Bromide
Strong Alcohol
Household Cleaners (Dental Equipment Only)
Citric Acids
Iodophors**
Ammonium Chloride
Accelerated Hydrogen Peroxide (0.5%)
Chemical Composition
Phthalaldehyde
Quaternary Ammonium
Glutaraldehyde
CAUTION
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 on abrasive scrubbers or 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.
Cleaning the Light

18
Cleaning the Light, Continued
Cleaning Reector and Cover
NOTE: Use only denatured alcohol to clean the glass reector. Use only mild soap and water to clean
the plastic reector cover.
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 reector. (See “Bulb Replacement” for bulb
removal).
Use a clean, soft** facial tissue dampened with denatured alcohol and gently wipe the surface of the reec-
tor and the bulb. The plastic reector 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 discolor-
ation of the handles. We recommend covers specically 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 reector 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 reector.
Do not use any solvents, abrasives, abrasive cloths or cleaners,
as they may damage the coated surface of the reector.
