Section 3
System One Pre-Installation Guidelines
SPECIAL NOTE: Installation and repair of this equipment should be performed by
qualified persons only. Medical Illumination International, Inc. does not warranty any
damage occurring as a result of improper installation.
It is recommended that this installation manual be completely reviewed prior to
installation.
Before installation, check to insure the following minimum conditions are provided:
•The structural ceiling mount is designed to support a vertical load of 175 lbs and an off
center moment of 450 ft-lbs. The structural mount should meet all local building codes.
A structural mount that does not meet these minimum conditions can cause serious
injury and/or property damage.
•Use the template provided to drill the six mounting holes for the ceiling casting sub-
assembly. If these are going to be through holes drill 7/16” diameter holes. If these will be
threaded holes use hole size consistent with fastener being used.
•It is recommended that the System I surgical lighting system be mounted directly over a 4-0
junction box. If this is not possible the input power supply lines should be wired in
accordance with all applicable building codes.
•The supply circuit line must be as follows:
120 VAC lights-110-120 VAC 50/60 Hz, single phase, three wire, capable of supplying 525
watts @ 5 amperes.
230 VAC lights- 220-240 VAC, 50/60 Hz, single phase, three wire, capable of supplying 525
watts @ 2.5 amperes.
•The power supply circuit must be in compliance with all applicable building codes.
•The light head switches secondary transformer power only. It is recommended that the
System One Surgical Lighting System is connected to its own supply circuit with integral
circuit breaker. The circuit breaker will act as the supply main disconnect switch.
Failure to provide a circuit meeting these minimum standards or complying with
local building codes can cause a shock hazard.
•Check the length of the ceiling rod supplied to make sure that it is the proper length to install
and operate the light without interference or over reach.(See ceiling Rod Calculation Pages
8-12)

GENERAL INFORMATION
The System One solo ceiling mount is shipped in three separate cartons. The ceiling casting
assembly, hardware kit and installation manual is in one carton. The arm assembly, cable
assembly and ceiling rod is in one carton. The head assembly and lamp holder assembly is in
the last carton.
Note: There are 5 standard length rods for different ceiling heights. Verify that your ceiling rod
length is correct for your ceiling height (See Page 8). If not correct please contact customer
service. For ceiling heights greater than 11 feet the ceiling rod will be shipped separately.
Prior to installation insure that all components shown in Figure 6 are present.
WHEN REMOVING PARTS FROM THE SHIPPING CARTONS, BE CAREFUL NOT TO
DAMAGE THE COMPONENTS OR BREAK ANY GLASSWARE. IMPORTANT:
THOROUGHLY CHECK EACH BOX FOR PARTS THAT MAY BE LOCATED IN AREAS
THAT CAN BE OVERLOOKED.

•Loosen the three 3/8-24 hex screws in the ceiling casting.
•With the ceiling casting laying on the floor or on a bench, slide the ceiling rod into the hole in
the ceiling casting in the direction shown in Figure 7. Push the rod through the casting
exposing the hole at the end of the rod.
•Install the 3/8” diameter dowel pin through the ceiling rod and seat inside the groove
provided in the ceiling casting.
Failure to install the 3/8” diameter dowel pin can cause the arm to fall from the
ceiling causing serious injury and/or property damage.
•Tighten the three 3/8-24 Hex head screws to secure the ceiling rod into place.
Failure to tighten the 3/8-24 hex screws can cause the arm/head assembly to
become unstable causing serious injury and/or property damage.
•Slide the cable assembly through the center of the ceiling rod with the Molex connector
protruding approximately 1” from the shaft protruding from the ceiling rod.
