Ceiling Mount 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:

← recommended

Medical Illumination strongly recommends that the ceiling structure be designed to the weights and moments for the worst case (double ceiling). Designing for the heaviest model with the highest load/torque will ensure adequate support for all models.

A structural mount that does not meet these minimum conditions can cause serious injury and/or property damage.
A sloped or vaulted ceiling will require a level mounting surface be constructed that meets the above listed requirements.

• The ceiling structure must be strong enough to support the weight and rigid enough to constrain rotation to less than 0.1° at the ceiling casting.
• The equipment may be mounted directly over a 4-0 junction box. Input power supply lines should be wired in accordance with all applicable building codes.
• The supply circuit line must be as follows: 100-240VAC, 50/60 Hz, single phase, three wire, capable of supplying 200 Watts.
• The equipment is not deemed compatible with any sort of electrical dimming device. Use line voltage only.
• The power supply circuit line must be routed and wired to the wire harness in compliance with all applicable building codes.

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.
Means of Isolation
The Means of Isolation disconnects (Isolates) the light from the source of power. This isolation akes it safe to work on the light. In the case of a ceiling mounted light, the means of isolation is the circuit breaker that supplies the power to the circuit. In the case of the Wall, Floor or Floor UPS, the means of isolation is the cord. Unplugging the cord isolates the light from power.

Ceiling Structure Construction and Mounting

The Ceiling Mount system will experience various levels of dynamic off center moment during regular use. Therefore, it is crucial that the ceiling structure be strong enough to uphold the weight of the system and support the positioning arms and light head without deflection. The owner and/or owner’s contractor has the final responsibility for the strength and rigidity of the ceiling structure. An inadequate ceiling structure may result in serious injury, unintended drift,
and/or equipment damage.
Because the ceiling structure is the owner’s responsibility, the design and construction recommendation shown below covers only one of the many possible alternatives that can be used. Medical Illumination highly recommends that the owner consult a structural engineer prior to designing and installing the ceiling structure.

Recommended Ceiling Structure Construction Details

The illustrations below are suggested mounting schemes per 2001 California Building Code – Section 1632A: Anchorage and Seismic. For any other mounting scheme, please consult a structural engineer and/or professional contractor for the best solution for your situation.
Installation and repair of this equipment should be performed by qualified persons only.
Medical Illumination does not warranty any damage occurring as a result of improper installation.

Ceiling Structure Construction and Mounting
Improper fastening of the ceiling casting can cause serious injury and/or property damage.

• Mount the Ceiling casting to the ceiling structure using four 3 /8” DIA Grade-8 bolts with nuts and washers as shown in Figure 3.

Arm Cable Termination

Figure 5: Arm Cable Termination
(Note: Ceiling Mount Assembly with a Single with Power Supply)

The DC Power cable is attached to the DC Power Terminal on Mounting Plate Assembly so that it can be tested as a complete system prior to packaging. To shorten the cable length, route the DC Wire Harness through the Wire Pass-Thru and then out of the center hub. Then run the cable through the Down Tube and position the Down Tube over the center hub aligning the Wire Pass-Thru recesses. Position the connector at 2” past the end of the Down Tube and
remove the slack to measure the excess cable length to be removed.
Disconnect the cable from the DC Power Terminal and cut the excess length from the cable.
Then strip and reconnect the three wires back to the DC Power Terminal observing the polarity: First connect the Green w/Yellow Stripe wire to the Mains Earth Ground terminal, then the Black wire to the Terminal labeled “Black” and then the Red wire to the Terminal labeled “Red (+24VDC)”. For a dual light configuration, connect the second DC wire harness to the other power supply in the same manner.
For ease of installation, install the Down Tube on the Ceiling Mount using the three (3) of the ¼-20 x½” Flat Socket Head and tightening sequentially. Ensure the Wire Harness Connector(s) exceed the open end of the Down Tube and that the wires are hanging unencumbered.

Protective Earth Ground Warning, to avoid risk of electrical shock, this equipment must be only connected to supply mains with protective earth.

Unpacking the Light System
All MI Products all are packed in a similar manner (see illustration) and the instructions for installation are the same. Once the carton is open the Installation Manual can be found on top of the Foam Pad. It is highly recommended that the installation be performed by at least two people.

Unpacking the Light System

To begin the installation, remove the Upper Light Head Foam Pads and move the Light Heads to a safe place for mounting after the Mounting Assembly is securely installed. Use the Light Head Pads to protect the Light Head until it is installed.
Note: due to its size, the packaging for the Dual MI-1000 requires the second MI-1000 Light Head to be packed in a separate carton.
Remove the Mounting Assembly Covers, Hardware Kit and Down Tube from the packaging.
With the Arm Assembly still in the Foam Packaging, carefully lift the Foam Packaging and Arm Assembly out of the Carton and place the Foam/Arm Assembly near the light installation. The Carton can also be cut away to access the Foam Packaging from the Carton. The Mounting Assembly will be in the very bottom of the Foam Packaging.

Installing the Light System
Once all of the components have been unpacked, install the Mounting Assembly to the ceiling structure using four (4) 3/8” diameter, grade 8 blots with nuts and washers. Following Ceiling Structure Construction and Mounting nstructions and ensure that the assembly is level and shim the assembly if necessary. Once the assembly is securely mounted, install the down-tube using the three (3) ¼-20 Flat Head Screws. Note: A small amount of synthetic grease applied to the inside wall of the down-tube will help prevent binding.

Ensure that any grease or lubricant used contains no hydrocarbons so that it is nonreactive with oxygen gas.

Installing the Arm Assembly

It is recommended that a scissor-lift be used to lift and mount the Arm Assembly. If a scissorlift is not available the installation can be performed by two people. In either case, carefully lift the Foam Packaging up to the Down Tube. Connect the Light Head Power Connector(s) and then Slide the Arm Shaft up into the Down Tube. Align the holes on the Down Tube to the Arm Shaft and install the remaining six (6) ¼-20 Flat Head Screws

Finishing the Arm Assembly

Once the Arm Assembly is securely mounted, lower the Foam Packaging from the Arm Assembly. Use EXTREME CAUTION when removing the Foam Packaging in that the Extension Arm(s) and the Articulating Arm(s) will both rotate freely once the Foam Package is removed.

Endo Mode
The MI-1000 also has an Endo (Endoscopy) Mode integrated into the lights’ dimming capabilities. The output in this mode produces low level lighting for use during endoscopic procedures. To put the MI-1000 into the Endo Mode, at any dimming level, press and hold the dimming button for 3 seconds.
Power Failures
If the light experiences a power interruption for any reason, the light is programmed to return to the dimming level that was applied before the power failure. This feature is intended to maintain the same lighting intensity when the power is restored and is applicable to the intensity level, the Endo Mode and the off position.

Positioning the Light Head
Ensure that the Light is properly installed before attempting to operate the light and arm mechanism.
To position the light head and arm over the work area, firmly grasp the Sterilizable Handle and bring the light head or arm to the desired location. Adjust the tilt of the light head by holding the Sterilizable Handle and rotating forward or backward. The light head can revolve around the Yoke/Arm connector by tilting the light head and rotating the head using the sterilizable handle.
The arm should move smoothly and remain at the desired position.
Each rotational joint in the arm assemblies allows 540° of rotation before the internal stop mechanism engages. The light head can rotate 300° on the yoke before the internal stop engages.

Maintenance
Fuse Replacement

IMPORTANT: Make sure that the power supply disconnected to the light before replacing the fuse(s).
Lights that are connected directly to supply mains require 1 fuse per light head
Lights that are plugged into wall outlets require 2 fuses per light head
Locate the fuse holder locations:

Bottom of Wall Bracket
Floor Model| On the Power-Supply Assembly located on the bottom side of the Base| Position the Floor Base on its side

Use only Medical Illumination fuses. See the following table to identify the correct fuse for your model. All fuses must be 250VAC, Slow-Blow. Failure to do so could result in personal injury and/or property damage.

LED Maintenance
If one or more LED(s) are off and/or generate noticeably dim light output, contact our customer service department at 818-838-3025. The LED’s are not readily replaceable by end users and should only be serviced by Medical Illumination or facility authorized maintenance personnel.

Spring Tension Adjustment Tool
ENSURE THAT THE ARM/LIGHT HEAD IS IN ITS HIGHEST VERTICAL POSITION BEFORE ATTEMPTING TO ADJUST THE ARM TENSION. DO NOT OVERTIGHTEN.

The Spring Tension Adjustment Tool (1000736) is required to adjust the spring tension on all MI Spring Arms. This wrench is included in the hardware kit and combines the “Lock” hex drive and the “Adjustment” hex drive into a single wrench. A 5/16” combination wrench (not supplied) is required to Lock and Unlock the Spring Tension Adjustment mechanism.
For safety, it is recommended that the box end of the combination wrench be used when locking the adjustment screw (see illustration).

DO NOT ATTEMPT SPRING TENSION ADJUSTMENTS WITHOUT THIS WRENCH.

Adjusting the Spring Arm
IMPORTANT The Spring Arm MUST be rotated up as far as it will go in order to access the spring-tension ADJUSTMENT SCREW and LOCK NUT.
To adjust the spring-tension of the Spring Arm the adjustment screw must first be “unlocked”.
To do this, carefully insert the Spring Tension Adjustment Wrench (P/N: 1000736) through the split-rubber receptacle until the smaller hex seats in the ADJUSTMENT SCREW socket and then slide the LOCK (outer) hex upwards until it seats in the LOCK NUT socket. While holding the Wrench stationary, use the 5/16” combination wrench (not supplied) to turn the outer Hex counter- clockwise a quarter of a turn. The ADJUSTMENT SCREW is now unlocked and the spring tension can be adjusted.
To adjust the spring tension, pull the outer hex back so only the ADJUSTMENT SCREW socket is engaged and rotate the wrench handle counter-clockwise to increase tension and clockwise to reduce the tension.
IMPORTANT The wrench MUST be removed before rotating the Spring Arm vertically to check the adjusted arm tension. Once the spring tension has been set and the Light Head balances, reinsert the Wrench until the small hex seats in the ADJUSTMENT SCREW Socket then slide the outer Hex upwards until it seats in the LOCK NUT socket then while holding the wrench stationary, use the 5/16” combination wrench to lock the LOCK NUT clockwise and the ADJUSTMENT SCREW into place.

Handle Sterilization
Remove sterilizable handle by pressing the button near the base of the handle and pulling the handle off the handle post. See the following illustrations.
Sterilize the handle utilizing steam sterilization of minimum 250° Fahrenheit for a minimum of 30 minutes in compliance with AAMI-SSSA-1988: Good Hospital Practices, Steam Sterilization and Sterility Assurance, or an approved equivalent method.

Cleaning Instructions

• The front lens is made from a UV resistant polycarbonate plastic that has an external hard coating to resist scratching. Clean the lens using glass/plastic cleaner or mild soap and water mix. It is very important to use a clean, soft cloth to avoid any scratching of the diffuser. Never spray the cleaning fluid directly onto the lens surface, but instead spray into clean cloth and then wipe the lens.
• Clean the light housing and arm using mild soap and water mixture. Apply this mixture to a clean cloth and wipe down the light head and arm. Never spray the cleaning fluid directly onto the light head or arm, but instead spray onto clean cloth and then wipe the light head and arm.
