Backwash - GE GXOF18K Owner's Manual & Installation Manual

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 at the lowest location possible
NOTE: For easier installation, remove the top cover (Figure 3).
cover forward and lift up.
1. INSTALL BYPASS VALVE ( Actual bypass may differ from drawing)
• Remove top cover (fi gure 3) and remove plastic shipping plug and wire from valve outlet .
• 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.
Make sure to read the the hardness bleed screw settings on page 91 of this manual
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 2 cm 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 illustrations on page 5.
• BE SURE INCOMING HARD WATER SUPPLY IS DIRECTED TO THE SOFTENER
VALVE INLET PORT. If house water fl ow is from the left, use a plumbing crossover as
shown in Fig. 1, page 5. If house water fl ows up from the fl oor level, turn the bypass valve
upside down as shown in Fig. 3C.
• 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 fi ttings onto plastic fi ttings, 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 fi ttings.
4. CONNECT AND RUN THE VALVE DRAIN HOSE
IMPORTANT: If you want to attach the drain fi tting to a rigid tube, see Step 4A .
• Assemble drain fi tting as shown in Fig. 4.
• Use the provided drain hose to attach to the valve drain fi tting. To keep water
pressure from blowing the hose off, use a hose clamp to secure in place. Cut
the necessary length and use the remainder in Step 5.
• Locate the other end of the hose at a suitable drain point (fl oor 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.
The water softener will not work if water cannot exit this hose during
recharge.
• 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 recharge. Also provide an air gap of at least
4cm 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 2 m above the fl oor. Elevating the hose may cause a back-pressure that could
reduce brine draw during recharge.
