Step-By-Step Installation Instructions; Feed Water Supply - GE Smart Water PNRV18ZWH01 Installation Instructions Manual

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 Fig. 2A below. A typical installation for existing homes using the saddle valve is shown in Fig. 2B below.
A. PREFERRED INSTALLATION
1. Turn off the cold water supply.
2. Complying with plumbing codes, install a fitting on the cold
water pipe to adapt 1 ⁄ 4 " OD tubing. A typical connection is
shown in Fig. 2A (parts not included). Make sure a water
supply valve is used.
B. OPTIONAL INSTALLATION
Where codes permit
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 Fig. 2B.
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.
