D) Flush water through drinking water faucet for 10 minutes to remove carbon fines. Check for

Alternate Installation
This alternate installation will require the purchase of additional fittings to be used with the water supply
adapter. It will be necessary to remove a section of the cold water line to the main faucet. This cold water
line is typically 1/2-inch inner diameter and 5/8-inch outer diameter plastic tubing. Adapter fittings for this
tubing can be either barb type (based on the inner diameter), or compression or quick connect (based on
the outer diameter).
See Illustration A for possible fitting combination. If barb fittings are used, hose clamps must accompany
them. If compression fittings are used, tube inserts should also be used. Always use Teflon
male threaded connections.
