Good news, we now sell the Epic Smart Shield with a stand alone faucet and if you already have an Epic Smart Shield, yes you can attached the Epic Smart Shield to a stand alone sink. Most stand alone faucets come with 1/4 inch tubing. We usually recommend John Guest Angle Stop Valve 3/8 to 3/8 to 3/8 - Part Number - ASVPP2LF. The other piece we use is a John Guest Super Speedfit - Stem Reducer. You would want the 1/4 to 3/8 Stem Reducer - Part Number PI061208S so it will fit the tubing of your faucet on the clean (outlet) side of the Epic Smart Shield manifold. This would be the piece you would plug into our manifold on the clean water side (blue sticker) and run the 1/4 inch line to your stand alone faucet.
So from your cold water valve, you will place the John Guest Angle Stop Valve on top of it instead of our cold water adapter (you can set that aside because you won't using it). From the John Guest Angle Stop Valve, you will use our 3/8 tubing up to the inlet side of the Epic Smart Shield manifold. On the outlet side of the manifold (where the blue dot is located), you will insert the John Guest Super Speedfit - Stem Reducer. Then hook up the faucet's 1/4 tubing to the female end of the John Guest Super Speedfit Stem Reducer and you should be all set.
