Install Piping
1. Depending on the type of softener system and the installation parameters, required pipe lengths and piping
accessories will vary. See
to aid the installation. If the layout drawings are not sufficient for your appli-
cation, consult the Culligan dealer for specific installation guidelines.
NOTE The use of unions and inlet and outlet isolation valves is recommended to facilitate the servicing of the
system. It is also recommended a full flow by-pass line be provided.
CAUTION! All soldering MUST be done on any connections requiring soldering prior to connect-
ing the main control valve. The main control valve will be damaged if it is connected at
the time of soldering.
2. Follow good plumbing practices for installation. These include:
a. Check threads and make certain that they are clean and free of foreign matter.
b. Fittings must be free of cracks or chips.
c. Prepare threads with either a pipe dope sealant or Teflon tape.
d. Make certain that the fittings are not cross threaded during the assembly process.
e. Do not over-tighten fitting or threaded pipe being inserted into a cast or forged part.
CAUTION! Never connect two dissimilar metals (such as copper and steel) together. The use of
dielectric unions or schedule 80 PVC or PVC plastic to break the connection is highly
recommended in order to reduce the risk of galvanic reaction and subsequent corrosion.
CAUTION! The media tank must never be subjected to an internal vacuum or it might be dam-
aged. Drain line suction can be prevented by piping the system in similar fashion to
. A vacuum breaker may be installed on either the inlet or the
outlet side of the vessel as close to the vessel as possible, preferably between the
vessel and any isolating valves. If an installation has a booster pump downstream
of the vessel, install the vacuum breaker on the outlet side. Do not install a vacu-
um breaker on the drain line. Use a vacuum breaker, such as Culligan 00401584 or
01003701. Multi-tank systems will require at least one vacuum breaker per tank.
