Installation requires a clean, level opening. Begin by checking the structural integrity of the reveal. Use the provided glazing packers to ensure the frame is perfectly square within the aperture; failure to do so may prevent the opening mechanism from operating smoothly. Seal the exterior joints with high-quality exterior-grade silicone to prevent water ingress.
For maintenance, clean the PVC frames with a soft cloth and mild soapy water, avoiding abrasive chemicals that could scratch the finish. Periodically lubricate the locking mechanism and hinges with a light, non-acidic machine oil to ensure long-term ease of use. Keep the trickle vents free of dust and debris to maintain consistent airflow.
