Before installation, verify that the gap between the window frame and the wall is filled with fire-resistant rock wool to ensure a proper seal. During routine maintenance, avoid using corrosive cleaning agents and regularly check the lubrication of hardware components to prevent sticking or jamming during operation.
Test the reliability of the locking mechanism every six months to ensure automatic closure in the event of a fire. Please note that fire-resistant windows must not be modified or have their glass replaced without authorization; any structural changes require re-testing of fire-resistance performance by a professional agency.
