4.1. Installation environment
4.1.1. General
• Use only brine salts designed for water softening. Do not use ice melt salt, block, or rock salts;
• follow State and local codes for water testing. Do not use water that is micro-biologically unsafe or of unknown quality;
• when filling media tank, first place the valve in backwash position, then do not open water valve completely. Fill tank slowly
to prevent media from exiting the tank;
• when installing the water connection (bypass or manifold) connect to the plumbing system first. Allow heated parts to cool
and cemented parts to set before installing any plastic parts. Do not get primer or solvent on o-rings, nuts, or the valve.
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.
