Installation & Maintenance Tip: Ensure the frame is securely mounted and level in the pool shell before re‑installing the grate. Check that required suction‑outlet flow does not exceed the grate’s rated capacity. Inspect the grate annually for cracks, chips or damage—replace immediately if compromised to maintain VGB safety compliance. When cleaning, use a soft brush and mild detergent; avoid solvents that might degrade the plastic material.
