1. Junction box location: 
please fix the power supply and junction box in the place shown on the drawing.

2. Mirror support panel: 
In order to utilize heat energy more effectively, usually apply a 9-18mm thickness plywood panel to support the mirror from wall, In installation situation, the cable lead of defogger may have some surplus length after cable connection. Then we suggest opening a hole on the plywood panel as shown in the drawing to hold the cable so that mirror is stable and flat after installation. 

3. Cable connection: there is no live pole & neutral pole difference on defogger’s cable, connect the cable with power supply by connector.

4. Fix the mirror on wall: apply some neutral silica glue to the plywood panel, and place mirror to the designated position.
