             Section 1: Listing of Warnings and Cautions

The following is a summary of safety precautions which must be observed when operating or servicing this
lighting fixture. WARNINGS indicate the potential for danger to personnel, and CAUTIONS indicate the potential
for damaging equipment. The precautions are repeated (in whole or in part) where applicable throughout the
manual. Carefully read all precautions before proceeding to use or service this equipment.


WARNING – PERSONAL INJURY HAZARD:
       Be sure electrical service is shut off and locked out and tagged out at disconnect switch or fuse box
       before beginning any maintenance on this lighting fixture. Also, be sure outer cover and lamp holder
       are cool before touching.

       Repairs and adjustments should be attempted only by experienced technicians fully acquainted with
       this equipment. Use of inexperienced, unqualified persons to work on the equipment or the installa-
       tion of unauthorized parts could cause personal injury or result in costly damage.

       Do not attempt to replace lamp unless power is turned off at the variable intensity controller by
       disengaging the circuit breaker(s), and lighthead has cooled sufficiently.

       Do not attempt to clean lighthead unless power is turned off at the variable intensity controller by
       disengaging the circuit breaker(s), and lighthead has cooled sufficiently.

       Do not use lighting fixture if red band is visible below rubber cap at top of vertical suspension tube.

       The nuts on the ceiling mounting bolts for the Centra 360 must be tight, using the required washers
       and lock washers.

       Do not attempt to remove the lighthead from the horizontal suspension arm without first removing
       the lighthead/arm assembly from the suspension tube.

       Make sure the suspension arm is positioned against the upper mechanical stop when the yoke is
       removed. Fingers, or other parts of the body, may be crushed if this precaution is not taken, as the arm
       will snap up when the yoke is removed.

       Never attempt to install or remove lighthead and arm unless arm is in the full upright position, against
       the knuckle stop (not vertical). Fingers, or other parts of the body, may be crushed if this precaution
       is not taken. The arm and knuckle contain a counterbalance and spring which will cause the knuckle
       to close rapidly with considerable force.

       Do not look directly at lamp while testing.

       The lighthead and suspension arm weigh 70 pounds (32 kg). Use enough personnel and/or equipment
       to safely perform this task.

       If the quartz lens has been damaged, personal protective equipment (hand protection, eye protection)
       should be used when servicing this assembly.


WARNING – EXPLOSION HAZARD:
       Do not use lighting fixture in the presence of flammable anesthetics.




                                                     1-1
                                                  764326-998
WARNING – PATIENT BURN HAZARD:
    Prevent patient skin and tissue burns. Potentially damaging radiant energy levels may be emitted by
    replacement lamps not qualified for use in Amsco® surgical lights. Use ONLY Amsco replacement
    lamps, part number P129362-228.


WARNING – PATIENT INJURY HAZARD:
    The plug button tether is anchored around the electrical wires routed from the yoke commutator. To
    ensure the plug button is anchored, run at least one of these wires through the plug button tether.


WARNING – ELECTRIC SHOCK HAZARD:
    Do not remove covers or perform service other than as described in this manual. Refer servicing to
    qualified service personnel.

    Turn power off at facility breaker, and lockout/tagout breaker prior to removing the front cover of
    Variable Intensity Control.


WARNING – RISK OF FIRE:
    Replace fuses (F-1 and F-2) as noted: 24V ~ FLM 20 250 V. Contact STERIS Corporation for replacement
    fuses.



CAUTION:
    Do not operate circuit breaker with the intensity controller knob in any of the "ON" positions.

    Do not bump lightheads into walls or other equipment.

    Use only recommended cleaning/disinfecting and/or antistatic agents on this light. Some degree of
    staining, pitting, and/or discoloration could occur if a phenolic-, iodophor-, or glutaraldehyde-based
    disinfectant is used on the surfaces of this light. Also, use of alcohol or aerosol spray cleaner/
    disinfectants containing a substantial amount of alcohol in the formula can damage the acrylic plastic
    lens.

    Use of any disinfectant solution other than those listed below may cause discoloration or deformation
    on the acrylic lens surface: Coverage® Spray TB Ready-to-Use Disinfectant Cleaner, Germicidal Cloth
    Impregnated Non-Woven Disposable Cloth, Coverage® Spray HB Ready-to-Use Disinfectant Cleaner,
    Coverage® HB Concentrate, T.B.Q.® Hard Surface Disinfectant Cleaner, or Coverage Plus® Concen-
    trated Disinfectant. Cleaning solutions other than those listed have NOT been tested for compatibility
    or effectiveness. Always follow manufacturer instructions for concentrations and use of cleaning
    products.

    Do not scratch optical coating on accessible portions of optical core when cleaning; always wear rubber
    gloves and use only a clean, white, lint-free cloth when wiping internal surfaces.

    Prevent leakage of fluids into interior of lighthead.

    Do not touch glass portion of lamp during re-lamping or cleaning.

    Manual actuation of the lamp change mechanism may result in permanent damage to the gear motor.




                                                  1-2

Make sure all three tabs for the funnel and cap assembly are fully engaged and the fit is tight when
locked in.

With brush housing removed, insulator slot should be approximately 1/2" wide.

Let lamps cool, then use cotton gloves or cloth to remove lamp(s) to prevent skin oils from contacting
glass.

The commutators at the inboard and outboard pivots have different diameters. Therefore, the brushes
are different because they have different radii.

To prevent voiding the warranty or damaging the equipment, use only STERIS replacement parts.

To prevent camera or camera replacement unit from falling, tighten thumb screws securely.

Do not use circuit breaker as routine operation ON/OFF switch.

Do not immerse the hand-held control in fluid.

When the lighthead is used with the camera, a
sterile handle is attached to the camera housing.
The sterile handle is used to position the lighthead,
and direct illumination from the lighthead.

    • The sterilizable handle can be removed for
      sterilization by unscrewing it from the
      threaded nylon extension.
    • Handle can be re-sterilized using standard
      hospital cycles. Always sterilize handle be-
      tween surgical procedures.
    • Following sterilization, allow the handle to
      air cool for three to five minutes before                      Figure 3-6. Metal Sterilizable Handle

6.3.1 Articulation of Lighthead in Yoke
1. Verify the lighthead moves smoothly from stop
   to stop inside yoke. Lighthead should move
   with minimum force and not drift when left in
   any position. If drift occurs, or force required to
   rotate lighthead seems excessive, the lighthead
   yoke friction needs to be adjusted (see Section
   7.6).
   NOTE: The following factory test procedure re-
   quires special tools and is included for reference
   only. This procedure should not be required for
   routine maintenance. Actual forces can be ad-
   justed to customer preference.
2. Attach a force gauge to the sterile handle and
   measure the maximum force required to rotate
   the lighthead within the yoke in two directions                      Figure 6-5. Rotation of Yoke in
