Frequently Asked Questions | AquaNuTech


1. Is the 4N1 user Friendly?

Yes, the standard hot/cold handle operates like any other full flow faucet with pulldown and spray features to dispense hot/cold water.

One touch on the touch sensor will illuminate blue LED and filtered water will be dispensed. Another touch ceases dispensing or the filtered water will automatically shut-off after 2-liters.

Touch and hold the touch sensor and red LED will fully illuminate, after a 3-second safety delay, and instant hot water will be dispensed. As a safety feature you must maintain touch on the sensor while dispensing the instant hot water. Cease touching and the immediately shutoff safety feature will be initiated.

2. How is the 4N1 better than a standard pull-out faucet or instant hot water dispenser?

The 4N1 combines all the features of a full flow faucet, filtration faucet, instant hot water dispenser and a filtration system into a single transitionally designed system. Daily duties at the kitchen sink become more efficient and convenient while giving you a space saving, eco-friendly product.
Inferior products can't match the superior dispensing performance and precise temperature control of the instant hot water dispenser. Filtered water is dispensed from this faucet as well, so no more going to the refrigerator, using plastic bottles or wasting money on filtered pitchers.
