Installation
4.1
Warnings
CAUTION
Do not lay down or flip over the softener at any time. The media may paste to the upper
distributor thus obstructing its slots and may therefore compromise the softener
operation.
Softener must be protected against freezing, which can cause cracking of the softener
and water leakage.
4.2
Safety notices for installation
• Observe all warnings that appear in this manual;
• only qualified and professional personnel are authorized to carry out installation work.

Installation environnement
4.3.1
General
• Use only brine salts designed for water softening. Do not use ice melt, block, or rock salts;
• keep the media tank in an upright position. Do not turn on its side, upside down, or drop it.
Turning the tank upside down may cause media to enter the valve or might clog the upper
screen;
• follow State and local codes for water testing. Do not use water that is micro-biologically
unsafe or of unknown quality;
• when filling the media tank with water, first place the valve in the backwash position, then
partly open the valve. Fill the tank slowly to prevent media from exiting the tank;
• when installing the water connection (bypass or manifold), first connect to the plumbing
system. 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.
4.3.2
Water
CAUTION
Do not treat water over 38°C, hot water would damage the softener and void warranty.
• If you are on a private well system, check minimum water pressure with an accurate gauge
(gauges on older water systems are often inaccurate). Static pressure that is less than 2 bar
may cause low flow rate and inadequate regeneration, depending by the pressure drop of the
system as a minimum of 1.38 bar dynamic pressure (on injector at 1.2 m
3
/h) of water is
required for the valve’s injector to operate effectively;
Mandatory
Do not exceed a maximum of 8.6 bar inlet pressure. Should this happen or be subject to
happen, it is necessary to install a pressure regulator upstream the system.
