💡 Tip: Allow at least 100 mm (≈ 4 in) clearance above the open louvers for safe operation and air flow.

Leave 50 mm (≈ 2 in) of clear space on the motorized beam side for housing and wiring.
Place a power outlet within 1.5 m (≈ 5 ft) of the control box.
Keep cables accessible before attaching roof panels.

Mark post corners using the outer-to-outer post dimension (3945 mm).
Verify diagonals before pouring footings — both should be equal to ensure a square frame.
Recommended footer: 400 × 400 mm (16 × 16 in) × 400 mm deep (16 in).
Leave 30 mm (1.2 in) tolerance around post anchors for alignment adjustments.
Level all posts first before securing the roof frames or motor components.
Confirm motor functionality and louver movement before final tightening.
Re-check clearances to avoid wall or furniture obstruction when louvers open.
