• Perform routine descaling in hard-water areas to prevent heating element buildup and maintain consistent steam output.
• Keep the generator installed in a dry, ventilated, and accessible location (cabinet, closet, or insulated mechanical space).
• Inspect the drain line and valves periodically to ensure full, unrestricted drainage after each cycle.
• Check LED diagnostic indicators regularly for early alerts such as water level, heating faults, or service needs.
• Ensure all 240V electrical connections are secure and serviced only by qualified technicians.
• Replace inlet water filters (if used) to reduce sediment entering the system and extend component life.
• Keep exterior stainless steel surfaces clean using a soft, damp cloth—avoid abrasives or harsh chemicals.
• Maintain proper steam room ventilation after use to reduce moisture stress on nearby materials.
• Use only genuine Mr. Steam replacement parts to ensure safety, efficiency, and warranty protection.
