Hydraulic Door Closer Hinge - Step-by-Step Installation Guide

Prepare Door and Frame: Ensure door thickness is >30mm, and mark hinge positions (150mm from top/bottom, plus optional 450mm from top for third hinge on heavy doors).
Create Slots (if needed): Machine slots on the door panel (facing the frame) to fit the hydraulic hinge, ensuring they’re aligned and same depth to prevent twisting.
Install Hinges: Place hinges into slots or directly onto the door, mark installation holes, drill 3mm diameter holes (depth 30mm), and tighten self-tapping screws.
Align Door and Frame: Ensure a 2mm gap at the top and appropriate gap at the bottom between door and frame. Install door on the frame, ensuring upper and lower hinges are on the same center line.
Adjust Functionality: Use a 5mm hexagonal key to adjust closing force (clockwise for stronger force, counterclockwise for weaker), and a 1.5mm key to switch between silent mode and lock-in-place function.
Test Operation: Open and close the door to verify smooth soft close, proper angle control, and secure locking.
