4.2. Softener connection to piping
TIP
To prevent your softener from incoming sediment and iron particles, Pentair recommends the
installation of a 100 μm pre-filter upstream the unit.
MANDATORY
The unit should be installed in accordance with the manufacturer’s recommendations and meet all
applicable plumbing codes.
4.2.1. Installation layout
4.2.2. Water supply line
The connections should be hand tightened using PTFE (plumber’s tape) on the threads if using the threaded connection type.
In case of heat welding (metal type connection), the connections should not be made to the valve when soldering.
NOTE
See chapter 3.1. Technical specifications, page 7 to identify the connections.
When pressurized, any composite tank will expand both vertically and circumferential. In order to compensate the vertical
expansion, the piping connections to the valve must be flexible enough to avoid overstress on the valve and tank.
In addition, the valve and tank should not be supporting any part of the piping weight. This is hence compulsory to have the piping
fixed to a rigid structure (e.g. frame, skid, wall…) so that the weight of it is not applying any stress on the valve and tank.
