GE GXSF27B GNSF35Z GXSF39B Step-by-step installation instructions, Install Bypass Valve

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.

O-ring seal goes into the outer groove only.

The clip snaps into the inner groove (see below).

NOTE: Threads on the bypass valve are 1″ male pipe. If 1″ pipes are needed, do not use the copper tubes and nuts included. Buy 1″ pipe thread female adapter, and plumb directly to 1″

•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.
