Installing the Neptune ATK is pretty simple especially since it comes with everything you need. The ATK uses a few different technologies to help make it be the safest ATO on the market today. Between dual optical level sensors and a backup float valve the safety doesn't end there. It also has IQ Fill which is a smart algorithm that will monitor how much it takes to fill your tank and if something were to go wrong it will never pump more than twice as much water as your tank may need. Installation is pretty straight forward, placing the magnetic sensor in your sump or return pump compartment to monitor the changing water level. Place the pump in your favorite ATO reservoir (we like the Trigger Systems ATO Containers) and plug everything into the FMM module. The ATK does not even need an Apex Controller to function. If you have an Apex, you get bonus features, however, without a controller, the ATK will work just fine.
