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.
1
Complying with plumbing codes, install a fitting on the cold water pipe
2
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.
Typical location
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
1
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.
2
Open the main water supply valve and several house faucets to purge
3
air from the system. Close faucets when water runs smoothly.
