Mechanical parts
• Do not use PTFE (plumber’s tape) lubricants such as Vaseline, oils, or hydrocarbon-based
lubricants. Only use 100% silicone lubricants;
• All plastic connections should be hand-tightened. PTFE (plumber’s tape) may be used on
connections that do not use an O-ring seal. Do not use pliers or pipe wrenches;
• All plumbing must be completed according to local standards;
• Soldering near the drain line should be done before connecting the drain line to the valve.
Excessive heat will cause interior damage to the valve;
• Observe the drain line requirements:
• Maximum height 1 m with inlet pressure of 2 bar. Add 50 cm for each additional bar of inlet
pressure;
• Do not use lead-based solder for sweat solder connections;
• Do not support the weight of the system on the valve fittings, plumbing, or the bypass;
• It is not recommended to use sealants on the threads. Use PTFE (plumber’s tape) on the
threads of the 2" BSP or in any other threaded connection in the valve.
• The installation of a pre-filter is recommended (100 µ nominal).
Integration constraints
The installation location of a water treatment system is important. The following conditions are
required:
• Level platform or floor;
• Room to access equipment for maintenance and adding brine (salt) to the tank;
• Total minimum pipe run to the water heater of 3 m to prevent hot water return into the system;
• Always install a check valve upstream of the water heater to protect the softener from hot water
return;
• Local drain for discharge as close as possible;
• Water line connections with shut-off or bypass valves;
• The installation site must meet any local and national standards;
• The valve is designed to tolerate only minor plumbing misalignments. The plumbing will not
withstand the weight of the system resting on it;
• Make sure all soldered pipes are fully cooled before attaching plastic valves to the plumbing;
• The existing plumbing should be in a good condition and free from lime scale. If in doubt, replace
it. It is always advisable to fit a pre-filter.
