Installation Instructions.
Feed Water Supply
Check and comply with local plumbing codes as you plan; then install a cold feed 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 third illustration below.
A. PREFERRED INSTALLATION
Turn off the cold water supply.
Complying with plumbing codes, install a fitting on the cold water pipe to adapt 3 ⁄ 8
″ OD tubing. A typical
connection is shown in illustrations at right (parts not included). Make sure a water supply valve is used.

B. OPTIONAL HOME INSTALLATION Where codes permit
*For 1/2" 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.
Turn off the cold water supply and attach saddle valve as shown in illustration at right.
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.
Close the water supply valve by turning the handle clockwise.
Open the main water supply valve and several house faucets to purge air from the system. Close faucets
when water runs smoothly. 3
