❸ Check to see what type of water line you have connecting the
cold water shut off valve to the cold water faucet. You probably
will have one of two types: a copper line or steel flex hose.
❹-A COPPER LINE: If you have a copper line, it is
highly recommended that you replace it with a 30" flexible
stainless steel hose that you can purchase at Home Depot or
Lowes for about $6.00. This will make the job much easier.
Remove the line at both ends; at the cold water shut off valve
and at the faucet. Discard this line and replace it with the 30"
steel flex hose.
❹-B Thread the female end of the diverter valve onto either the COLD water faucet stem or
the COLD water copper line running from the single handle faucet MAKE SURE the o-ring
stays in the female end of adapter. Tighten securely.
❹-C Thread the 1/2" female end of the 30" steel flex hose onto the male threads of the
diverter valve. Tighten securely.
❹-D Thread the 3/8" female end of the steel flex hose onto the cold water shut-off valve.
Tighten securely.
❺-A STEEL FLEX HOSE: Disconnect the hose ONLY at the faucet (end). You will
reuse this hose.
❺-B Thread the female end of the diverter valve onto either the COLD water faucet stem or
the COLD water copper line running from the single handle faucet. MAKE SURE the o-ring
stays in the female end of adapter. Tighten securely.
❺-C Thread the 1/2" female threads on the disconnected end of the steel flex hose onto the
male threads of the diverter valve. Tighten securely.
❻ Feed the 1/4" tubing connected to the IN quick connect connector on the bottom of the
product down through the access hole.
❼ Connect this tubing to the water adjust valve on the diverter valve. Tighten the nut securely
but NOT too much.

Instead of adjusting the water pressure (water flow rate) to the product using the faucet (standard countertop
installation option), you will adjust the water pressure (water flow rate) to the product using the water flow
adjust valve attached to the water supply line diverter valve. After you have turned the cold water shut off
valve back on (AND CHECKED FOR LEAKS), adjust the water adjust valve unit the water flow rate on the
product LCD displays reads between 1.8 and 2.5 liters/minute.
