GE GNSF18Z01 Owner's Manual & Installation Instructions page 7

Step-by-step installation instructions.
• Turn off the gas or electric supply to the water heater, in the possibility that the
water heater may be drained while draining pipes.
• Turn off the water supply to pipes to be cut and drain the house water pipes.
• Open both hot and cold faucets.
1. INSTALL BYPASS VALVE
• Remove plastic shipping plug and wire from valve outlet.
NOTE: Be sure the turbine
and support are firmly in
place in the valve outlet.
Blow into the valve port
and observe the turbine
for free rotation.
• Push the bypass valve (lubricate o-ring seals with silicone grease) into both ports
of the valve as shown in Fig. 3A.
• Snap the 2 large plastic clips in place, from the top, down as shown in Figures 3A
and 3B. Be sure they snap into place. Pull on the bypass valve to make sure it is
held securely in place.
2. MOVE THE SOFTENER ASSEMBLY INTO INSTALLATION POSITION:
• Be sure the installation surface is level and smooth. Sharp objects under the tank
may puncture it. If needed, place the tank on a section of 3/4 thick (minimum)
plywood. Then, place shims under the plywood as needed to level the softener.
3. PLUMB IN AND OUT PIPES TO AND FROM SOFTENER:
CAUTION: Observe all of the following cautions as you connect inlet and
outlet plumbing. See Fig. 1 or 2.
• BE SURE INCOMING HARD WATER SUPPLY IS DIRECTED TO THE
SOFTENER VALVE INLET PORT. If house water flow is from the left, use a
plumbing cross-over as shown in Fig. 1.
• If making a soldered copper installation, do all sweat soldering before connecting
pipes to the bypass valve. Torch heat will damage plastic parts.
• When turning threaded pipe fittings onto plastic fittings, use care not to
cross-thread.
• Use pipe joint compound on all external pipe threads.
• Support inlet and outlet plumbing in some manner (use pipe hangers) to keep
the weight off of the valve fittings.
4. CONNECT AND RUN THE VALVE DRAIN HOSE:
• Use the provided drain hose (20 length included) to attach to the valve drain
fitting. To keep water pressure from blowing the hose off, use a hose clamp to
secure in place.
• Locate the other end of the hose at a suitable drain point (floor drain, sump,
laundry tub, etc.) that terminates at the sewer. Check and comply with local codes.
IMPORTANT: If more drain hose is needed, it should be ordered from GE Parts
at 800.626.2002. The water softener will not work if water cannot exit this hose
during regenerations.
• Tie or wire the hose in place at the drain point. High water pressure will cause it to
whip during the back-wash and fast rinse cycles of regeneration. Also provide an
air gap of at least 1–1/2 between the end of the hose and the drain point. An air
gap prevents possible siphoning of sewer water into the softener, if the sewer
should "back-up."
• If raising the drain hose overhead is required to get to the drain point, do not
raise higher than 8 above the floor. Elevating the hose may cause a back-pressure
that could reduce brine draw during regenerations.
