Water Filtration system: 4 filters and 2 x UV lights.

Water Flow from the collection tank: Sediment filter, Carbon filter 1, Reverse Osmosis, Carbon filter 2, then the 1st UV Light. Additional UV light for cold water: All cold water is additionally sanitized by passing the water through a 2nd UV light.

Recycle Mode: Several recycle modes not only assure that the D-1 produces the freshest water available when you need it, recycling on power up and every 4 hours during normal operation for 20-30 min. (depending on mode) yields longer filter life & less maintenance.

2 speed fan: A 2 speed fan is used to allow the dealer or end user to select between maximum water production, or a quieter operation mode. The switch is on the back of the unit.

Quiet Operation Sound: measures less than 50dB maximum sound level (measured 1ft from the unit, when generating water).

Municipal Water Mode: Municipal water mode is designed to provide additional water source if atmospheric water generation can not keep up with demand. Municipal water requires an external pre-filter kit to maintain water quality vs. atmospheric water.

Note: Without a pre-filter, all of the standard filters, especially the Reverse Osmosis filter life will be much shorter.

If an external water source is present, and the Relative Humidity is above 40%. Any time the collection tank is empty, the unit will fill the collection tank from the external water source (takes about 1 min), and then shut off the external water source, and resume Atmospheric water production.

If an external water source is present, and the Relative Humidity is below 40%. Any time the collection tank is empty, the unit will fill the collection tank from the external water source (takes about 1 min), and then shut off the external water source. Atmospheric water production will resume if the R/H goes above 40%.

Hot Water Child Lock: Hot Water will only be dispensed if the Child Lock button is pressed before the Hot Water Button. The system resets after each use, or if no Hot water is dispensed for 30 seconds. The unit sounds a long warning tone if the Hot Water button is pressed without first pressing the Child Lock button. This can remind an adult to engage the Child Lock, or warn that a child is playing with the machine.

Filter Replacement Warning: The unit will remind the end user to replace each filter as required. Filter replacement timers can be reset at any time, if the filters are replaced early. The Sediment, Carbon filters (x2) & the Reverse Osmosis filter should be replaced every 12 months. The filters are accessible from the front of the machine, have quick disconnect connectors and the panel is easily removed to facilitate filter replacement.

Dolphin1 User Interface Liquid Crystal Display: The unit displays the current status of the machine with full animation on the front panel color LCD. Displays include Atmospheric water generation, filtering the water, dispensing Hot or Cold Water, Hot and Cold water tank temp, Heater and Cooler Status, UV Light Status / Failure, filter replacement, leak sensor, defrost sensor, the level of water in the collection tank and storage tank, etc.

All button presses respond with an acknowledgement tone and where appropriate, mode change on the LCD, or a long warning tone if the requested operation cannot be performed.
