1) Advisory Note

Always use a professional certified electrician to install any electrical

device that must be hard wired. These notes are guidelines only.

For your situation, consult a professional and adhere to local building codes

Weights: Medallions are decorative only and do not hold weight.

Any fixture must be hung by the electrical receptacle's threaded rod.

For heavy fixtures, re-enforce the ceiling joists or rafters to hold the weight.

2) Selecting the Right Medallion

3) Sizing the Medallion for your Light Fixture

Sizing is based on the Golden Rule called PHi

This is the ratio calculation PHi (1.618)

Here is a simple calculation to consider

1- (.618) = (.382) ie 38.2%

This keeps within the Golden Rule of Phi

18" medallion x 1.38 = a 25 inch medallion

No rules rule so select 29", 25" or what ever matches your design

Always remember that when you view the medallion mounted on the

ceiling it will appear much smaller from your perspective at a lower level

By selecting one that uses the golden rule calculation, it will appear to

be the right size with the correct visual distortion

4) Split Service & Hole Cutting

If required, all medallions can be split for reassembly so that you do

not have to take down a chandelier. We offer custom hole sizes

and precision splitting services ... see the following page

5) Preparation
Power: Make sure there is no power to the receptacle box by turning off the breaker or fuse and confirm no power with an electric tester Before you nail or screw into the ceiling make sure with a probe that there are no electrical wires in the proximity of where you will be nailing or screwing. Also beware of water pipes.
	Mark the Spot: Center the hole of the medallion to the receptacle box and trace out the outside of the medallion on the ceiling with a pencil
Wear a mask and lightly sand and remove all dust or popcorn plaster (stucco) from the ceiling prior to install to ensure a flat surface Special Note: Pre 1980 Beware that some popcorn ceilings contain asbestos check this out first and have a professional remove the popcorn coating
The Hole: Most octagon ceiling receptacle boxes are 3-3/4 inches Order your medallion with a precut specified hole or drill a hole yourself - See how we Drill Holes and Split medallions
Paint the medallion before you install - allow 24 hrs to dry

6) Get the Medallion Up There First !
The Approved Glue On various spots on the back surface, dab the approved construction adhesive Note: wear gloves read and follow the manufacturer's warnings The back of the medallion should not be painted and should be rough sanded if necessary so the glue will adhere ArchPolymerTM Limited Warranty is void unless the approved adhesive is sold with the medallion or panel Some construction adhesives are solvent based glue that may melt the product
Use 4 screws to temporarily hold the medallion or preferably use a brad nailer to affix the medallion to the ceiling Use only a few brad nails as they are just holding the medallion till the adhesive dries In the case of Neo-Plaster-GRG use screws only and countersink them to be filled later
Check to make sure the medallion is level on all sides If it is not use a small wedge to pry one side downward until all sides are even. This is the time to correct any unevenness before the glue dries Make sure you have pulled the wires through the center hole.

7) Fixing and Filling the Medallion
Allow 24 hours for the glue to dry Once dry use the approved Poly Spackling Compound to fill any holes and gaps between the ceiling and the medallion Wet sand OR let dry and sand the Spackle prior to painting We do not recommend caulking as it may shrink and cannot be sanded. Only certain caulking can be painted thus the spackling compound is a better product
