HLC CEILING MOUNTED LIGHT
PRE-INSTALLATION REQUIREMENTS:
To insure a safe and proper installation of HLC ceiling mounted light, certain guidelines con-
cerning building construction must be observed.
BUILDING REQUIREMENTS:
After determining desired location of light in reference to chair position (see illustration), some
alterations (framing, reinforcing), may be required and should be discussed with your local
contractor or builder. Major structural modications are not required, however the mounting
bolts used and area of ceiling mounted to should be able to withstand a 250lb. pull-out per
bolt. (This is needed to provide ample protection from side impact loads.)
ELECTRICAL REQUIREMENTS:
Standard 3-wire Romex or conduit w/junction box mounted per local code.
Power required: 0.53 amp at 115 VAC.
A full-size mounting template, dimensions, and suggested methods of installation are as fol-
lows:
This installation must be done by a licensed electrician only, in accordance with the National
Electrical
plicable.
Code(in the USA) or Canadian Electrical Code(in Canada), and local electrical codes as ap-

DUAL INTENSITY ON/OFF SWITCH
1. High Beam; push toggle to left
2. Low Beam; push toggle to right
Switch is conveniently located in light head, enabling intensity
to be changed from seated position.
Low Intensity - for longer lamp life and examining facial sur-
faces.
High intensity - for color matching and examining lingual sur-
faces.
BALANCE ARM ADJUSTMENT (Should drifting occur)
IMPORTANT; Use slot closest to head when making adjust-
ment for drifting of balance arm. Insert adjusting bar into slot
on top of balance arm, turn spring adjustment nut clockwise
for more tension; counterclockwise for less tension.
HEAD ANGLE ADJUSTMENT
IMPORTANT; Use slot closest to swing arm (H-shaped cast-
ing bracket) when adjusting angle of head. Insert adjusting
bar into slot on top of balance arm, turn head angle adjust-
ment nut clockwise for downward angle; counterclockwise
for upward angle.
Adjusting bar is supplied in envelope with Allen Wrenches.
Upward angle when turning
head angle sdjustment nut

BULB CHANGING
1. To install replacement bulb (BELMONT H-3), turn unit off and remove back cover.
2. Push in and turn counterclockwise knob of bulb retainer to remove bulb retainer.
3. Remove bulb by grasping lead wire and pull bulb from housing. Disconnect lead wire
when bulb is completely removed.
4. Clean new replacement bulb surface with alcohol, attach lead wire and insert new bulb into
housing.
5. After new bulb is seated in housing, insert and lock bulb retainer into position.
IMPORTANT; Do not touch glass with bare hand. Light bulb surface must be clean. Oil or body
moisture will affect light intensity and bulb life. If glass surface is touched, clean
with alcohol.
CLEANING
Use soft cloth or cotton only. Soak with alcohol. Clean both sides of lens. Inside surface of re-
ector can be cleaned with a soft damp or dry cloth. Back side of the reector should be wiped
gently with a soft cloth. Extreme care should be taken not to scratch surface or mar appearance
of painted surfaces. Exterior cleaning is all that should be necessary until after many months of
use.
LUBRICATION
A drop of oil once a year at pivot points will provide ample lubrication.
