A.) When the product flips over, the Frog @Ease SmartChlor Cartridge is empty. Remove the empty cartridge and replace with a new one. This system naturally sits at a tilt in the water. To check if the Frog @Ease SmartChlor Cartridge is empty, lift up and drain all the water from the system. You should be able if there is still SmartChlor left in the cartridge. If only a small amount is left attach a new Frog @Ease SmartChlor Cartridge and hook the old cartridge on the tether until it is completely empty. When empty, discard in trash or offer for recycling if available.
B.) After 4 months or when draining and refilling the swim spa, the blue Frog @Ease Mineral Cartridge must be replaced even if you hear the spent minerals inside.
