Installation Instructions
WATER SUPPLY
Check and comply with local plumbing codes as you plan, then install a cold water supply fitting. For new home
installation using standard plumbing fittings, see first two illustrations below. A typical installation for existing homes
using the saddle valve is shown in the third illustration below.
B. OPTIONAL HOME INSTALLATION
(Where codes permit)
*For 1/4″ OD or larger metal tubing only.
NOTE: Codes in the state of Massachusetts require
installation by a licensed plumber and do not
permit the use of the saddle valve. For installation,
use plumbing code 248-CMR of the Commonwealth
of Massachusetts.
1. Turn off the cold water supply and attach
saddle valve as shown in illustration below.
DANGER: To protect yourself from
serious injury or fatal shock, use a battery-
powered hand drill only to make the hole.
DO NOT USE AN ELECTRIC DRILL.
2. Close the water supply valve by turning the
handle clockwise.
3. Open the main water supply valve and several
house faucets to purge air from the system.
Close faucets when water runs smoothly.
