Single Ceiling Mount Installation Instructions
| The Burton FlexiMount™ Single Ceiling Mount System has been designed to be used with the Burton Flexible Arm Lights. These Lights are provided as Head and Arm assemblies which are authorized for use only with Burton FlexiMount ceiling mounts, wall mount or floor stand. Any other use will void the warranty and may cause a safety hazard.
PREPARATION
NOTE: BURTON RECOMMENDS THAT THIS LIGHT BE INSTALLED BY A QUALIFIED ELECTRICAL CONTRACTOR.
Tools Required: Drill, hack saw, 9/16" open-end wrench, wire cutter/stripper, Allen wrench, small flat-blade screwdriver.
Also Required: 3 mounting bolts and wire nuts for supply connections.
SPECIAL NOTE: To prevent sway and provide proper support to the Light, the ceiling mount must be attached to a structurally-sound ceiling. Most ceilings will require adequate reinforcing to hold the Light. The installing contractor is responsible for providing this reinforcement to suit the individual requirements of each installation. A typical reinforcement consists of a 1/4" steel plate, the bottom surface of which is flush with the inside surface of the finished ceiling (e.g. acoustical tile) and connected firmly to the structural ceiling. Sway braces (e.g. made of angle iron) are recommended when there is more than 12" between the structural and finished ceilings. Make certain the installed plate is level.
The proper height for the Light should be set by the end user. Typically the arms are installed 6' 1" (78") above the floor. This allows the light heads to be adjusted from 51" to 80" above the floor.
INSTALLATION
1. Mount the Ceiling Casting to the ceiling/Jct. Box Assy. Use (3) 3/8" bolts, split lockwashers and nuts. See back panel for support details.
2. Assemble the "Downtube" by sliding it up the center hole in the Ceiling Casting (a) until the top protrudes (b). Position the tube for desired lamp height and fasten the tube securely using the (2) setscrews. The "dog-point" setscrew must engage the mating hole in the Downtube. Depending on ceiling height, the Downtube may have to be cut (at the top) and a new hole drilled so the light will hang properly.
Note: The "Downtube" is pre-cut and pre-drilled at the factory for the average user having an exam room with a 9 foot ceiling (the light should be approximately 6' 1" above the floor when positioned horizontally). When installed in this "typical" room, there will be approximately 2 inches of tube showing above the ceiling plate. A longer Downtube (for higher ceilings) is available on special order. Be certain the setscrew engages the drilled hole in the tube.
3. Run the wire harnesses from the Transformer up a hole in the Casting (and plate), and inside the Downtube until the connectors stick out the bottom of the tube.
4. Connect the (115V-60Hz) supply lines[hot(load)/black, neutral/white, and ground/green] to the terminal block (a), using wire insertion technique of (b). Recommended size of the supply lines is 14 gage maximum (if larger gage wires are used, the terminal block connections will not be secure).
5. Install the outer Bell Housing over the Ceiling Casting and fasten it with the (4) 10-32 screws provided.
Note: Be certain to assemble the shield to the Downtube before assembling the extension arm to the Downtube.
6. Install the Extension Arm/Pivot Support onto the Downtube by first mating the connectors (a). Make certain that proper color coding is maintained; that is the brown wire from the tube is connected to the brown wire in the proper Arm, etc. After the proper electrical connections have been made, push the excess harness up the tube, and slide the Pivot Support into the tube. Make certain the (6) holes in the Pivot Support match the holes in the Downtube. Fasten the two together with 8-32 screws provided (b).
7. Attached the Light Head/Articulating Arm assembly to the Extension Arm by first lubricating the hollow Shaft lightly with grease and sliding it onto the mating hole in the Articulating Arm. To mating the connectors (a) run the (2) conductors from the Light through the hollow Shaft on the Extension Arm. Mate the connectors according to color code; there will be (1) unused wire which can be pushed back into the Extension Arm. Retain the Articulating Arm on the shaft using the provided brass Friction Plug, Spring, and Threaded Plug (b). Note that the Friction Plug must be oriented properly to "capture" the Shaft by riding down in the Shaft groove (c). Screw the Threaded Plug in until it is flush with the mating surface. It does not require full tightening to hold the Pivot Support assembly in place. It can be tightened for increased friction, if desired, after the overall assembly is complete.
8. Push the wires back into the Extension Arm, and, using a plastic mallet, gently tap the provided end caps into place. Also, align the provided Hole Plug in the hole on th etop of the Articulating Arm. Use a mallet to drive the Hole Plug flush. Fasten the cover plate to the Extension Arm using the 4-40 screws provided. Figure 8.
8a. Assemble the external friction parts provided in the hardware kit to the articulating arm, see diagram. Keep parts in order as found.
9. Energize the Light assembly by turning the Switch "ON" to check proper operation. Each Extension Arm should swing freely horizontally, but have slight restraining force due to friction of the o-rings in the central Pivot Support. The Extension Arm should swing back and forth about 320°. To prevent the internal wiring from becoming tangled it will not swing through 360° because of an internal stop.
The Articulating Arm should move freely up and down approximately +/- 40°, and horizontally back and forth through 320°. Built-in friction for both vertical and horizontal movement prevents drift of the Head/Arm. Note that the Articulating Arm will not swing through the center Downtube.
