1. Safety instructions
1.1 Symbols
Danger to life and limb! Caution!
Important instruction regarding the correct operation of the device
Observe strictly!
1.2 General safety instructions
Use only original spare parts and accessories that have been tested and approved by the manufacturer. The
manufacturer is not liable for damages caused by the use of non-original spare parts and accessories or improper
handling. Should these instructions not answer all your questions, please contact the manufacturer first.
1.3 Safety instructions - Electricity
An electric shock can be lethal or cause serious injuries; any non-authorized work on the electric system is
strictly forbidden!
Prior to cleaning works on the device or close to it, always unplug the apparatus as water
and current form a lethal mixture!
Only qualified installers are authorized to install the device.
Ensure that the socket is always readily accessible. If the cable of the device is damaged, replace it in order to
avoid any risk. Unplug the device prior to changing any setting in the electronic system. The apparatus is deliver-
ed with a mains adapter.
1.4 Safety instructions - Salt
The residual regeneration salt will be flushed out of the regeneration tank along with the waste water, which
should not be used for watering flowers or similar purposes. Observe the instructions in chapter „Installation site
requirements“ to ensure perfect safety when draining the waste water and the salt.
The indicated salt quantities refer to salt tablets. When using industrial salt (salt pellets
or blocks) quantities may vary.
1.5 Safety instructions - Temperature
Danger of scalding! Load resistances may become hot in operation and should not be
touched.
Vent the water softening system right after the connection to the water mains to ensure perfect safety.

Instructions for Use and Maintenance LEX Plus 10 Connect Water Softener
2. Foreword
To the customers‘ attention!
you made a very good decision in selecting this water softening system, as it stands for the
latest developments in the water conditioning technology.
The SYR LEX Plus 10 Connect Water Softener is designed to protect pipes and water heaters
against lime deposits, which reduce the water flow through the pipes and lead to a high energy
consumption. By protecting appliances and valves, the device prevents expensive repair works.
There are no restrictions for the field of application according to DIN 1988.
The ion exchanger resin is located in a tank. The ion exchanger resin is regenerated in several
cycles. The regeneration time is preset to 02.00 am. The control unit automatically adapts to
the consumers‘ habits. The LEX Plus 10 Connect Water Softeners do not provide softened water
during regeneration.
Synthetic pipes or other corrosion resistant pipes shall be installed in all cases, where
water (process water) of 0 ° dH (German hardness degree) flows through the pipes to
prevent corrosion. Galvanized or copper tubes can also be used in case of partial softening
(approximately 8 °dH). This stabilizes the remaining carbonate hardness particles and forms
the prerequisite for building up a homogenous protective coating in the downstream piping
system. Some particular cases require an additional dosage of minerals/mineral solutions.
The functional parts are made of high-quality materials, which all meet the local regulations
and specifications.
Verify that the device shows no visible damages as soon as it is delivered. In case of damage
caused by transport, directly contact the forwarding agency.
The warranty does not cover damages caused by improper handling or operation.
Please refer to the terms of delivery and payment of your local dealer for any further or other
claims.
To ensure trouble-free functionality, the regeneration salt used must comply with the
requirements of the European Standard EN 973 (former DIN 19604 standard). We recommend
Broxo or Solvay salt tablets.
We recommend to conclude a service contract to make sure that the
perfect functionality of all water treatment devices is verified on a
regular basis.
The ion exchanger resin is made up of small synthetic resin beads, which replace the calcium
ions causing water hardness with sodium ions.

3. How the system works
The water becomes „soft“. However, the ion exchanger resin absorbs only a limited amount
of hardness particles. Depending on the water hardness, the absorbing capacity of the resin
becomes depleted sooner or later and has to be regenerated.
Regeneration with this system means removing the hardness particles from the ion exchanger
resin.
The diluted salt brine that flows through the resin bed removes the hardness particles, which
are then directed to the sewer.
The regeneration process requires only a small amount of salt and complies with EN 14743 and
DIN 19636-100.
The water softening system undergoes automatic disinfection on a regular basis in order to
prevent microbial growth. The small amount of chlorine required for that process is generated
electrolytically from the brine sucked in during regeneration.
The regeneration is carried out automatically.
A water meter integrated in the device records the quantity of produced soft water, which is
summed up in the electronic system. When the value set for the raw water hardness is reached,
the electronic system triggers the required regeneration process.

Instructions for Use and Maintenance LEX Plus 10 Connect Water Softener
4. Installation site requirements
Follow these instructions in order to prevent any problem with the LEX Plus 10 Connect
Water Softener.
Install the water softener in a dry room, which is not liable to frost. The ambient temperature
should not exceed 30 °C.
The system requires a power supply (230 V, 50 Hz) under constant voltage.
It also requires a gravity flow connection to the sewer for the waste water hose and the salt
tank‘s safety overflow.
The water softening system is usually installed downstream of the protecting filter, the
pressure reducing valve (compulsory when the static pressure is equal to or exceeds 5.0 bar)
and upstream of a dosing pump (optional).
To prevent huge damage on the installation site due to a leaking device or supply line (for
instance in an office, medical practice etc.), it has to be ensured that during the personnel‘s
absence the water and power supply are interrupted upstream of the system.
We recommend our leakage detector Safe-T Connect with an integrated floor sensor
(serial number: 2421.00.010).
Do not disconnect during the regeneration process.
When restarting the device after a service interruption, repeat the same steps as for the initial
start-up (cf. the instructions for installation and start-up).
The water to be softened has to be clear, free of solid impurities as well as iron and manganese-
free.
An additional water analysis may be helpful: we will be glad to offer you support by analyzing
your water sample free of charge. Send us your sample with our accompanying letter that you
can download in the Internet under www.syr.de > Service > Formulare.

6. Service / Service interruption
As the water softener works automatically, you will have to
refill salt from time to time only, but at the latest when the
display signals that the salt level is low. The SYR Connect
control indicates the number of weeks left until the salt
stock has to be refilled.
The salt stock should not be reduced to the extent that the
liquid level is above the salt, as otherwise it will rise exces-
sively when refilling salt. The SYR Connect control will signal
a malfunction.
When using SYR Connect via Internet with SYR‘s App or the
web interface of a PC, the SYR Connect control will indicate
in due time that the salt level is too low.
When no softened water or just a little quantity of softe-
ned water is drawn off, the water softener will automatically
carry out a forced regeneration after 4 days at the latest to
ensure perfect hygiene (in compliance with EN 14743 and DIN
19636-100 (DVGW-test guideline).
When restarting the water softener after a service
interruption, the start-up process has to be carried out again
(cf. the relevant instructions for installation and start-up).
Should the main water supply of the water softener be
interrupted (main shut-off valve closed or on „bypass“), the
power supply of the device has to be interrupted as well.
