Installation Instructions
FEED WATER SUPPLY
Check and comply with local plumbing codes as you plan, then install a cold feed water supply fitting.
A. PREFERRED INSTALLATION
1. Close the cold water supply valve under
the sink.
2. Unscrew the flexible tubing from the
supply valve that connects to the COLD
water riser.
3. Install the feed water adapter* that is the
diameter to match either the 1/2
″ or 3/8″
plumbing in your location. DO NOT
OVERTIGHTEN.
*Notice the direction of the feed water
adapter and coupling. It is installed
differently in order to match either the
1/2
″ or 3/8″ plumbing in your location.
B. OPTIONAL HOME INSTALLATION
Where codes permit (Requires additional parts)
*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.
Saddle valve is available through GE Parts
and Services at 1.800.626.2002, part number
WS15X10023. Self piercing saddle valves are
not recommended.
1. Turn off the cold water supply and attach
saddle valve as shown in illustration
below.
DANGER:
Many homes are
electrically grounded through the plumbing.
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.
