Caution - material
Risk of damage due to wrong lubricant use !
Do not use petroleum-based lubricants such as Vaseline, oils, or hydrocarbon-
basedlubricants.
Do not use silicon grease.
Use only P-80
• 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;
• existing plumbing should be in a good shape and free from limescale. In case of doubt, it is
preferable to replace it;
• all plumbing must be completed according to local codes and installed without tension or
bending stresses;
• 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;
• do not use lead-based solder for sweat solder connections;
• observe the drain line requirements: maximum 1 m high at 2 bars inlet pressure. Add 50 cm
for additional 1 bar at the softener's inlet;
• the valve is designed for minor plumbing misalignments. 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 25.4 mm (1") NPT elbow, the drain line connections, and other NPT/BSP
threads.

Integration constraints
Location of a water treatment system is important. The following conditions are required:
CAUTION
The surface for installation (platform or floor) must be solid, flat and level.
Mandatory
Drain must be capable of handing a maximum backwash flow rate of 19 L/min.
• locate the softener as close as possible from drain discharge point and within 12.2 m
maximum of drain discharge point, respecting minimum drain line diameter advises given at
chapter Drain line connection [
• flat and firm level platform or floor;
• room to access equipment for maintenance and adding brine (salt) to tank;
• constant electrical supply to operate the controller;
• total minimum pipe run to water heater of 3 m to prevent backup of HW into system;
• always install check valve before water heater to protect the softener from HW return;
