How does the display on the Opera smart kitchen sink work?

The Self-Powered Smart Display runs on water flow: a small dynamo inside the panel makes the power, so it needs no battery and no electrical point. It shows the water temperature in °C and the total running time while water flows through the pull-out faucet, the waterfalls or the glass rinser.

Is the Opera thermostatic?

No. You set the temperature with the One-Knob Temperature Control and read it on the display. Turn the knob clockwise from cold to hot; it sets the pull-out, both waterfalls and the glass rinser.

What is the sink made of?

The bowl is handmade 304-Grade stainless steel with welded corners. The pull-out faucet body and the RO tap are 304-Grade stainless steel, and the chopping board, strainer basket and vegetable basket are 304-Grade steel. The control panel has a brass core, a stainless steel outer body and a glass top.

Will the black finish or the steel rust?

The bowl is PVD Matt Black, colour bonded to the steel in a vacuum chamber, not painted on, with a Nano coating that resists moisture and rust. Under it, the 18% chromium in 304-Grade steel forms an invisible layer that protects against rust. Clean with mild soap and a soft cloth. No acid, bleach or scrubbing pads.

What water pressure does it need? Do I need a pump?

The sink needs about 40 PSI (2.8 bar) at its water inlet. With a high overhead tank (about four floors up) and ¾ Inch pipes with few bends, no pump is needed. Otherwise fit a 1.5 HP pump with a 24-litre tank.

How do the Flute Keys work?

Each outlet has its own round key: press to turn it on, press again to turn it off. Left to right, the keys are for the small waterfall, glass rinser, pull-out faucet, big waterfall and RO tap. Several outlets can run together; the flow is lower when they do.

What are the two waterfalls for?

The big waterfall gives a shower-style flow. The small waterfall gives a smooth sheet of water. Both run hot or cold.

What spray modes does the pull-out faucet have?

Three: Spray, Stream and Sector flow. The round button on the head gives Sector flow; the two-way switch gives Spray (top) or Stream (bottom). The hose is 1.5 m long with a counterweight that draws the head back.
