3. Installation Steps (General)
- Prepare the Wall: For recessed mounting, carefully cut an opening in the wall according to the specified wall cut size (19" H x 17 3/8" W x 4" D). Ensure no electrical wires or plumbing are in the cutting area. For surface mounting, identify stud locations for secure attachment.
- Assemble Cabinet Body: If the cabinet body is not pre-assembled, follow the included assembly instructions to construct it.
- Mount the Cabinet:
- Recessed Mount: Insert the cabinet body into the wall opening. Secure it using the provided mounting screws through the cabinet's side flanges into the wall studs or appropriate anchors.
- Surface Mount: Position the cabinet body against the wall. Mark drilling points for the mounting hardware. Drill pilot holes and secure the cabinet to the wall studs using the provided screws. If studs are not available, use appropriate wall anchors.
- Connect Electrical: The cabinet comes with a standard electric plug. If hardwiring, cut off the plug and connect the wires to your existing vanity light circuit. Ensure all electrical connections are secure and comply with local electrical codes.
- Attach Mirror Door: Carefully attach the mirror door to the cabinet body using the hinges. Ensure the door opens and closes smoothly.
- Install Glass Shelves: Insert the adjustable glass shelves into the desired positions within the cabinet.
For detailed visual instructions, refer to the installation diagrams provided in the separate instruction manual included in your package.

Maintenance
- Cleaning the Mirror: Use a soft, lint-free cloth and a non-abrasive glass cleaner. Spray cleaner onto the cloth, not directly onto the mirror, to avoid liquid seeping into the edges.

- Regular Inspection: Periodically check all mounting hardware and electrical connections to ensure they remain secure.
