Installation Instructions
5. Plumbing Preparations: Unscrew the two plastic nuts (#1) and pull on the two
brass connectors (#4) to remove them from the bypass assembly. Next remove the
white plastic rings (#2) and the O-rings. (#3) See Figure 1
•
Solder at least 6” of pipe to the brass connectors before reassembly.
(See Figure 2)
•
After soldering is complete, cool the pipe and connectors. Slide the
plastic nuts (#1) over the brass connectors (#4). Place the white plastic
split rings (#2) into the grooves closest to the end of the brass
connectors (#4). Reassembly the connection kit onto the bypass
assembly.
Warning:
When assembling the installation-fitting package (inlet and outlet), connect the fitting to the
plumbing system first and then attach the nut, split ring and O-ring. Heat from soldering or sol- vent cements
may damage the nut, split ring or o- ring. Solder joints should be cool and solvent cements should be set
before installing the nut, split ring and O-ring. Avoid getting primer and solvent cement on any part of the O-
rings, split rings, bypass valve or control valve.
6. Plumbing: When connecting the water softener to the existing plumbing, make
sure the inlet water is connected to the inlet of the softener. Arrows on the valve body
indicate direction of flow. Make sure the bypass valves are in the correct position See
Figure 3 .
Note: All plumbing should be done in accordance with local plumbing codes.
Warning:
The control valve, fittings and/or bypass are designed to accommodate minor plumbing
mis-alignments but are not designed to support the weight of a system or the plumbing.
