The drain adapter kit isinstalled onto your sink drain pipe above the P-trap.See Fig. 7.• Use another existing drain in your home(See Fig 10 & 11) This is usually used in remotelocation type installations. The drain tube from theReverse Osmosis Filter runs directly to an opendrain. See Fig. 10 & 11.NOTE: An incorrectly connected drain point cancause water to leak from the faucet’s air gap.NOTE: Local code may dictate which type of draininstallation is used. Other than local code, eitherdrain install type may be used in both under thesink or remote location installations.

Assemble the drain tubing connector to the drainadapter using the ferrule and nut. Snug the nut, butdo not tighten. See Fig. 8.NOTE: Locate so that the drain tubing from theReverse Osmosis faucet will run straight to theadapter, with no dips, loops, or kinks. See Fig. 9.5.
