INSTALLATION NOTES

•The SKYTRON Surgical Lighting Fixture is nor­mally shipped in two to three crates, depending on
the model. A carton containing the Vertical Support
Tubes, miscellaneous hardware, and various in­structional materials is packed separately.

•Follow the Installation Instructions and utilize the
Installation Check List to assure proper installation.

•Additional materials required for proper installation
include Blue Loc-Tite compound.

•Special adapter plates for mounting SKYTRON
surgical lights on existing mounting structures are
available. Contact your SKYTRON representative
for special application details.

•Contact SKYTRON representative for Seismic
calculations if applicable.

UNCRATING

•Should any damage to the fixture be
noted while uncrating, further unpack­ing should be stopped and the container
with all the wrappings held for inspec­tion. The transportation company should
be notified immediately so an inspector
can be sent. Consult the Damaged
Shipment Claim Procedure sheet for
further details.

•Personnel uncrating SKYTRON sur­gical lights should be aware that they
are delicate medical equipment and spe­cial care in handling should prevail
throughout installation.

•Use extreme caution when removing
the contents from the crates to prevent
damage to the lights. Leave the
lightheads in their crates until ready to
install.

•If the lighthead must be set down after
it is removed from the crate, always lay
it on the front face on the foam shipping
block. Do not lay it on the front face.

1. Mounting Plate

a. Check the strength and stability of the mount­ing structure. It should be fabricated of steel and
welded or bolted to the structural ceiling. It should
be braced in a manner that will allow no twisting or
lateral motion. A steel stiffener plate should be
used to connect the 3/4" diameter "all-thread" sup­port rods and to provide an attachment base for the
angle-iron sway bracing. The 3/4" diameter sup­port rods should be mounted in a 9-1/2" square
pattern and should extend 2-1/4" below the finished
ceiling. See Mounting Structure details in the

back of this booklet.

b. Install the SKYTRON mounting plate on the
threaded rods between jam nuts. The plate should
normally be located 1-1/4" off the finished ceiling
(measured from the bottom of the plate) and accu­rately leveled, within 0.1 degree, using a digital
level. Tighten the jam nuts securely. See figure 1.

WARNING

The mounting plate must be accurately
leveled to prevent lighthead drift.

UNCRATING PROCEDURE

Open the top of the lighthead box and remove the
packing material, remove the sterilizable position­ing handle and remove lighthead from the crate.

NOTE

Details may vary depending upon model
and support structure fabrication.

ALL fixtures use METRIC fasteners.

INSTALLATION PROCEDURE

The lighting fixture should be installed in the

following sequence:

1. Mounting Plate

2. Radial Arm Assembly and Ceiling Cover

3. Vertical Support Tubes/ Balance Mechanisms

4. Lightheads

NOTE

•The multiple arm assemblies are easier
to handle during installation if the arms
are left taped and tied together.

•In some cases it may be necessary to
connect the electrical wires to the radial
arm junction box before the arm assem­bly can be bolted to the mounting plate.

a. Install the Radial Arm Assembly(RAA) onto
the mounting plate using the bolts provided. Tighten
the mounting bolts securely.

CAUTION

TO AVOID BLOWING FUSES, DO
NOT TURN MAIN POWER TO FIX­TURE "ON" UNTIL ALL LIGHTHEADS
ARE INSTALLED AND ALL WIRING
CONNECTIONS ARE COMPLETED.

b. Observe color codes and connect the trans­former wires to a 120VAC, 60Hz power supply
using a DPST wall switch

NOTE

WARNING

Apply Loc-Tite to all of the 5mm mount­ing screws and use a 3mm allen wrench
to tighten the screws.

Figure 2. Radial Arm Installation

a. Install the VST on the BOM, apply Loc-Tite to
screw threads and secure VST with the allen
screws provided. See figure 3.

Connection of the fixture wires using
Crimp Connectors is recommended .

c. Install the ceiling cover and secure. See

figure 2.

3. Vertical Support Tubes/Balance Mecha­nism

NOTE

Determine correct placement for each
Balance Mechanism(BOM)/Vertical Sup­port Tube(VST) on the radial arm assem­bly. The longest VST goes into the top
radial arm.

b. Observe the wire colors and connect the
wires from the radial arm to the corresponding
BOM/VST wires using crimp connectors. See
figure 4.

c. Insert the vertical support tube into the radial
arm receptacle. Observe any screw color codes,
apply Loc-Tite to screw threads, and secure the
BOM/VST assembly with the 5mm mounting
screws. Repeat procedure for any remaining BOM/
VST assemblies.

b. Remove the four (4) screws from the lighthead

mounting stub.

c. Install the lighthead mounting stub into the
support arm and secure with the screws previously
removed. See figure 6.

4. Lighthead

a. To make it easier to install the lighthead,
locate the support arm of the balance mechanism
so that it points inward toward the ceiling cover.
This will prevent the radial arm from moving when
installing the lighthead. See figure 5.

Figure 6. Lighthead Installation

d. Pull the lighthead down and remove the
Above Horizontal Limit Stops from the BOM. See
figure 7.

WARNING

DO NOT remove lighthead when sup­port arm is in down position; The bal­ance mechanism will be severely dam­aged and may result in bodily injury.

terminals) should be 20V ± 0.2V. See figure 9.

CAUTION

The internal circuitry used in the Stellar
system requires the use of a true RMS
type digital voltmeter to accurately
set the bulb voltage. Premature bulb
failure will result from incorrect voltage.

DAMAGED SHIPMENT CLAIM PROCEDURE

Whenever a shipment suffers damage while in the
custody of the transportation company, the re­sponsibility lies with the transportation company,
and the value of the damages can be collected from
the transportation company if the proper proce­dures are followed.

When a shipment is received in a damaged condi­tion and due to the appearance of the containers
such as a broken crate, torn wrapping, or smashed
carton, the contents may have been damaged.
That fact should be noted on the Bill of Lading
offered by the transportation company. An ex­ample of an applicable statement would be;
ceived in good order except as noted" or "Crate
damaged, possibility of concealed damage." The
addition of these types of statements on the ship­ping documents will automatically give grounds for
starting a claim.

If damage cannot be identified on the exterior of the
container, but is found when the container is opened,
further unpacking should be stopped immediately
and the container with all wrapping or packing
materials should be held. The transportation com­pany should be notified so an inspector can be
sent. Failure to follow either of these two proce­dures may result in an inability to file a claim and
collect for damage done.
the sender without such an inspection may prevent
filing a claim, because it will divide the responsibility
for damage and in many cases the
transportation company will return the shipment to
the sender without charge after the inspection.

Returning the container to

"Re-

The claim itself may be filed by either the shipper or
consignee, but the consignee must notify the trans­portation company and the shipper that the damage
has occurred. Remember that refusal of the ship­ment or failure to note the possibility of damage on
the shipping documents may jeopardize the claim.
Also, acceptance of a damaged shipment which
has been processed properly to allow for filing a
claim, will not jeopardize the position of the con­signee. In any case, SKYTRON will see that
damage which is not the fault of the consignee or
his agents is corrected, if the transportation com­pany does not honor the claim, as long as SKYTRON
receives the full cooperation of the consignee in
filing the claim.

Some of the papers needed for filing a claim are in
the hands of the consingnee after the shipment has
been received. If SKYTRON must file a claim, we
will request these papers by name from the con­signee at such time as the claim is under discus­sion.

We will require the originals of these papers

and not copies.
Knowledge of the procedures outlined above and

your cooperation in submitting damaged shipment
claims will help both you, our customer, and
SKYTRON by assuring the integrity of our prod­ucts from manufacturing to installation.
