•
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.
5.3.2. Water
•
Water temperature must not exceed 43°C;
•
a minimum of 1.4 bar (dynamic pressure on injector) of water pressure is required for the
regeneration valve 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.
5.3.3. Electrical
There are no user-serviceable parts in the AC/DC transformer, motor or controller. In the event of a
failure, these should be replaced.
•
All electrical connections must be completed according to local codes;
•
use only the power AC/DC transformer that is supplied;
Mandatory
The use of any other power transformer than the one supplied void the warranty of all
electronic parts of the valve.
•
the power outlet must be grounded;
•
to disconnect power, unplug the AC/DC transformer from its power source;
•
an uninterrupted current supply is required. Please make sure that the voltage supply is
compatible with the unit before installation;
•
make sure the controller power source is plugged in;
•
if the electrical cable is damaged, it must imperatively be replaced by qualified personnel.
5.3.4. Mechanical
•
Do not use petroleum-based 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;
•
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;
