Section 3

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:

Ceiling Mount Weight: Lb Moment: Ft Lb

Single Ceiling 70 215

Double Ceiling 115 350 ← 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 provide adequate support for the heaviest, and will not significantly increase the cost of the lightest. The design margin will also allow for flexibility for future product upgrades.

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 Single Ceiling mount supply circuit line must have as a minimum:

100-240VAC, 50/60 Hz, single phase, three wire, capable of supplying 65 Watts @ 1.5A.

The Dual Ceiling mount supply circuit line must have as a minimum:

100-240VAC, 50/60 Hz, single phase, three wire, capable of supplying 130 Watts @ 3A.

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.

WARNING: Secure the source of power using the means of isolation, before proceeding with electrical work.


Section 3

Ceiling Mount Pre-Installation Guidelines (cont’d)

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

The Ceiling Mount system will experience various level 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 may result in 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.

Figure 3: Recommended Ceiling Structure Construction


Section 3

Ceiling Structure Construction and Mounting (cont’d)

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 A325 bolts with nuts and washers.

Safety Label

Figure 4: Ceiling Casting Mount Diagram

WARNING: To avoid risk of electric shock this equipment must only be connected to a supply mains with protective earth.

Insert the ceiling rod up through the ceiling casting until the hole in the ceiling rod becomes visible. Insert the dowel pin into the hole in the ceiling rod and lower the rod in the ceiling casting, making sure the pin is seated securely in the indentation on the ceiling casting.

Securely tighten the two set-screws located in the casting.

Failure to install the dowel pin can cause the arm/head assembly to fall from the ceiling causing serious injury and/or property damage.

The ceiling casting must be properly grounded during installation. This can be done by mounting the casting to a suitable material that will function as a ground conductor, or a wire lead that must be attached to the ground screw on the casting then routed to proper ground.

Note: Ceiling rod must be plumb. Adjust the nuts/washers accordingly.

Note: The ceiling casting itself must be electrically grounded to maintain proper grounding reliability.


Section 3

Extended Ceiling Mount Installation (cont’d)

If ceiling rod is not plumb, unwanted arm drifting may occur.

Feed the wire harness through the ceiling rod and route to a junction box. Leave sufficient wire to extend slightly beyond the bottom of the ceiling rod. Important: To achieve proper

grounding reliability, the green ground wire from the wire harness MUST be properly fastened to the grounding screw located on the ceiling casting. Make all electrical connections in compliance with all applicable electrical codes.

Failure to comply with local electrical codes can cause a shock hazard.

WARNING: Secure the source of power using the Means of Isolation, before proceeding with electrical work.

Slide the casting cover up the rod extension and over the casting. Similarly, slide the collar to the casting cover, then tighten the set screw to hold the cover in place.

Feed the wire harness through the lower ceiling rod with the rod in the direction shown. Slide ceiling rod up through ceiling rod extension until the holes in the ceiling rod align with the upper holes in the ceiling rod extension.

Section 6

Arm Adjustment

The arm has been pre-adjusted by the factory. Should further adjustment be necessary, utilize the following procedure.

 Release the arm friction brake by loosening the set screw inside the Friction Adjustment

Hole with an Allen wrench (3 or 4 turns). This allows the spring to move freely for a more accurate adjustment. The arm is expected to droop as the brakes are loosened.

 Remove the white rubber Cover from the spring tension adjustment slot as shown.

 Move the arm vertically until the adjustment nut is visible down inside the Slot.

 Engage the tabs of the Adjustment Wrench into the slots in the Adjustment Nut. Turn the nut in the direction of the arrow as shown in the figure to increase the arm tension. Check the progress as you go until the required adjustment is reached.

Do not over tighten the nut. Doing so could result in equipment damage.

 When proper tension is achieved, the arm should travel up or down an equal distance when the same amount of force is applied from above or below. When moved to the maximum Up position, it should travel back down about 1-1.5 inches (until brake is set).

From maximum Down position, it should travel back up about the same.

 After the spring tension is adjusted, re-tighten the brake until the desired resistance is obtained.

 Replace the spring tension adjustment slot cover.
