1. Introduction
2. General description
You have just purchased one of the finest water conditioners on the market.
At UST-M we understand that the quality of water treatment products is an investment in your family
health and well-being. Realizing this fact we do not just sell products, we sell quality you can count on.
That is why in our warranty you will find no fine prints, which are usually the most important for the
Customers.
UST-M warranty is clear, straightforward and comprehensive.
Water softeners with automatic controller are dedicated to improve water quality, especially to lower
its hardness. Water considered „hard” contains large amount of minerals (calcium and magnesium
compounds). They can precipitate creating scale. It can narrow pipes diameter, limiting or in some cases
even blocking the flow. Scale deposits on the heating elements increase the energy consumption for
water heating.
Hard water can also lead to water supply installation and household appliances damages, which
removal can be expensive. Moreover, hard water increases detergent consumption and creates stains
on fixtures.
UST-M’s water softeners soften water so effectively thanks to the usage of high quality ion exchange
resin. They are equipped with by-pass allowing easy installation. Competitive price in combination with
low exploitation costs make this softener an excellent choice.
The softener has been approved for use by the National Institute of Hygiene.

5. Installation
Before installation make sure the package contains all parts. The package should contain:
nWater softener
nTransformer
nInstruction manual
nBy-pass
nHex key
n1” coupling
Before installation please read this manual carefully and comply to all safety precautions related to
starting-up and operation. In case of any questions please contact the dealer or the manufacturer.
Before installation remove all parts out of the box. Check if the device has not been damaged during
transport. All comments should be reported to the seller immediately.
The device should be removed from the box carefully. The softener can be heavy, so when carrying,
grab it "from the bottom". It is forbidden to move the device grabbing hoses, by-pass and other delicate
parts. Avoid moving across the floor. It is forbidden to drop the device, putting it on sharp or angular
edges and turning upside-down, because this may lead to permanent damage of the softener. The
device should be transported only in an upright position, otherwise it may damage the controller.
When installing the softener:
- make sure you have the knowledge or hire a professional
- make sure the placement area is clean, flat, stable and it can withstand the load of the softener filled
with water and salt
- make all connections according to the local laws and regulations
- to seal all threaded, gasket-free connections use PTFE tape only. Using tows is prohibited and may
result in connections damage.
Softener must be preceded with at least 50 micron rating sediment pre-filter (eg. UST-M’s PS or PP).
Drain hose and brine overflow hose should be connected to the sewage system separately
using siphon and air gap, in order to prevent the backflow of odors and bacteria inside the
device.

treatment was between 4 and
5 German degrees of hardness
( approx. 89 ppm).
8. Adjustng treated water hardness
The softener allows to adjust water hardness supplied to the object.
Adjusting can be done by turning the screw, located on the left side of the controller or by using a by-
pass valve.
Turning the screw clockwise the hardness of water supplied to the object is increased. Water hardness
can also be adjusted by turning the blend adjusting knob on a by-pass valve in a way shown on the
picture below.
You can also adjust water hardness supplied to the object (the higher angle of turn ‘A’, the higher water
hardness).
ATTENTION! If yellow water
appear in the installation,
BACKWASHING and RINSING
must be repeated.

9. Salt level sensor and free chlorine generator (Lotus softener only)
The principle of operating of the free chlorine generator and the salt level sensor.
The salt level sensor reminds about the need to fill up the salt in the device. When activated in the menu,
it will constantly monitor the level of salt in a solution. If a concentration drops below the set value, an
alarm will be triggered. The alarm is activated by flashing icon and an audible noise. It can be set in a
“silent” mode in any hour range. During this period no sound will be heard. The alarm can be removed by
a short disconnecting of the power supply.
Activation/deactivation of the salt level sensor
The salt level sensor is also the free chlorine generator.
The the free chlorine generator minimizes the risk of bacterial growth inside the softener. It eliminates
the problem of biofilm formation and resulting microbiological corrosion. It produces free chlorine from
brine during a ion exchange resin regeneration process. This function can be activated or deactivated
according to ones needs. When activated, the generator will produce free chlorine during every
regeneration.

10. Holiday mode
When planning a longer break in the use of the softener (longer than 30 days) it is recommended to set
it in a HOLIDAY MODE. It is important due to the possibility of bacterial growth on the media, which may
lead to its irreversible damage and the need of replacement. Activation of the HOLIDAY MODE allows
ion exchange resin rinsing and a removal of microorganisms at the same time.
During holiday mode the device does not draw salt. To set the softener in a HOLIDAY MODE do the
following:
nPress the MENU button
nSelect HOLIDAY MODE using the UP/DOWN buttons
nConfirm by pressing the SET/REGEN button
nSelect ACTIVATE using the UP/DOWN buttons
nConfirm by pressing the SET/REGEN button
nSet the end of the holiday mode. Set every following digit using the UP/DOWN
buttons and confirm using the SET/REGEN button
nPress the MENU button 3 times
The device is now in the holiday mode.
This mode turns off automatically after specified time.
