5.3.5. Mechanical
• Do not use PTFE (plumber’s tape) lubricants such as vaseline, oils, or hydrocarbon-based
lubricants. Use only 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 codes;
• 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 1 m high at 2 bars inlet pressure. Add 50 cm for each additional 1 bar 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 prefilter is always recommended (100μ nominal).
5.3.6. Integration constraints
The 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 tank;
• total minimum pipe run to water heater of 3 m to prevent backup of hot water into system;
• always install a check valve before 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;
• must meet any local and state codes for the installation site;
• the valve is designed for minor plumbing misalignments. Do not support the weight of the
system on the plumbing;
• 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 limescale. If in doubt, replace
it. The installation of a pre-filter is always advised.
