6. STEP-BY-STEP INSTALLATION GUIDE

Step 1: Preparation Before Installation
- Verify opening dimensions, check wall plumbness/squareness, and clean opening from dust and debris.

Step 2: Assemble the Door Frame / Cover
- Assemble top jamb and side jambs using corner brackets and screws to form a rigid U-shaped frame.

Step 3: Apply Foaming Agent
- Place frame into opening, level with shims, and inject expanding PU Foam (Golden Foam) evenly into gap between frame and wall.

Step 4: Install the Hinges
- Fix 4 hinges onto door leaf hinge stile and securely attach opposite hinge leaves to WPC jamb frame.

Step 5: Install the Door Lock
- Insert mortise lock body at 115 cm height, fit cylinder, handle escutcheons, and lever handles.

Step 6: Adjust the Door Gap
- Check margins between leaf and frame (3 mm uniform gap on top/sides) and adjust hinge screws/shims if necessary.

Step 7: Install the Line (Architraves / Casings)
- Clip or glue WPC architrave lines into designated frame grooves on both inner and outer wall faces.

Step 8: Install the Floor Stopper
- Drill floor at door travel end and secure floor stopper using rawl plug and screw.

Step 9: Apply the Sealant
- Apply continuous silicone/acrylic sealant along architrave-to-wall and frame joint interfaces.

Step 10: Cleaning
- Remove protective films, clean excess foam or sealant residue, and inspect door operation.
