Electrical safety is the primary concern. Ensure all integrated pumps and LED lighting systems carry CE, UL, or RoHS certifications. For the North American market, GFCI (Ground Fault Circuit Interrupter) compatibility is a must. If the unit includes a reservoir, verify that the waterproofing grade is at least IP68 for all submerged components. Furthermore, check if the supplier provides material test reports (MTR) to confirm the grade of stainless steel used, especially for projects in coastal areas with high salinity.
