It uses three float switches rather than one: N1 sets the working level, N2 sits above it as a safety cut-out if N1 sticks, and N3 sits in the reservoir to protect the refill pump from running dry. Everything runs at 12 V low voltage from a 100–240 V power supply, with plug connections on every cable for easy installation and servicing.\u003c\/p\u003e\n\u003cp\u003eN1 has a delay function, so ripples and surface movement do not set the pump switching on and off. If N1 fails and the water rises to N2, refilling is interrupted, which Aqua Medic describes as a safety shutdown for a defective level sensor. When the reservoir runs low, N3 stops the pump and triggers an optical and acoustic alarm. Status lights on the controller show refilling in progress, low reservoir water with an audible beep, and power on. The supplied refill pump draws 0.5 to 5.0 W at 3.5 to 12 V DC and delivers up to 350 L\/h with a maximum head of 220 cm, feeding through 2 m of 8\/12 mm hose. The supplied N1 and N2 holder needs about 13 cm at the aquarium or sump rim, and both sensors sit above the water line with their floats pointing upward.\u003c\/p\u003e\n\u003ch3\u003eUsage \u0026amp; Application\u003c\/h3\u003e\n\u003ch4\u003eWhen to Use\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReef aquariums:\u003c\/strong\u003e Keeping salinity steady by replacing evaporation with fresh RO water.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSump systems:\u003c\/strong\u003e Holding a constant level in the return section so the pump never runs low.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolidays and busy weeks:\u003c\/strong\u003e Top-up continues without daily attention.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen-top tanks:\u003c\/strong\u003e Higher evaporation that would otherwise mean daily hand-filling.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eInstallation \u0026amp; Setup Guide\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCables first:\u003c\/strong\u003e Connect every sensor and the pump before switching on the power supply.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit N1 and N2:\u003c\/strong\u003e Mount them on the supplied holder at the desired level and safety level, floats upward.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet the reservoir:\u003c\/strong\u003e Stick the pump and N3 to the bottom with the suction cups, and keep the reservoir no higher than the hose outlet.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoute the hose:\u003c\/strong\u003e Fix the outlet above the water so no siphon can form; keep sensors free of algae.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Specifications \u0026amp; Highlights\u003c\/h3\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree float switches:\u003c\/strong\u003e Working level, overfill cut-out and reservoir low-level.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDelay switching:\u003c\/strong\u003e Ignores surface movement for steady operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDry-run protection:\u003c\/strong\u003e Stops the pump and sounds an alarm when the reservoir is low.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e12 V low voltage:\u003c\/strong\u003e Safe voltage at the tank and in the reservoir.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlug-in cables:\u003c\/strong\u003e Every component connects and disconnects without tools.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eProduct Details\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Aqua Medic (Germany)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e AM50277\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBarcode (GTIN\/EAN):\u003c\/strong\u003e 4025901141702\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e ATO Systems \u0026gt; Automatic Top-Up System\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRefill Pump:\u003c\/strong\u003e 3.5–12 V DC, 0.5–5.0 W; max. 350 L\/h, max. head 220 cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Supply:\u003c\/strong\u003e 100–240 V AC, 50\/60 Hz input; 12 V DC output\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensors:\u003c\/strong\u003e 3 float switches (level, safety, reservoir)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose:\u003c\/strong\u003e 2 m, 8\/12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIn the Box:\u003c\/strong\u003e Power supply, controller, 3 float switches, refill pump, 2 m refill hose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensor Holder:\u003c\/strong\u003e Needs approx. 13 cm at the rim\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 24 months via the dealer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTarget Environment:\u003c\/strong\u003e Marine and freshwater aquariums with sumps\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"The Coral Shop","offers":[{"title":"Default Title","offer_id":67990029107262,"sku":null,"price":308.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/0778\/8606\/files\/aqua-medic-refill-system-20-ato-aquatic-supplies-australia-1027101.webp?v=1793319268","url":"https:\/\/thecoralshop.com.au\/products\/aquamedic-refill-system-2-0","provider":"The Coral Shop","version":"1.0","type":"link"}
