nents:
1. Controller
2. Brine lid
3. Main hood
4. Brine tank
4. Description of function
4.1. Meter regeneration
In normal use the LCD display alternates between following
indications:
• Time of day
• Remaining capacity (m3)
•Flowrate
• Number of days until next regeneration
• Installer name
• Softener name.
Atthetimeofregenerationthecontrollercomparestheremai-
ningcapacitywiththereserveanddecidesifitisnecessaryto
start the regeneration. KS20S softener is equipped with a
blending device to insure a residual hardness in softened
water.
Controller
During regeneration the LCD display alternates between
following indications:
• Cycle number
•Cyclename
• Remaining time for the current cycle.
Whenallthecyclesarefinished,thevalvecomesbacktothe
service position.
The controller of KS20S softener can manage:
• Normal brining
• Proportional brining
• Counter current regeneration (upflow ).
4.2. Valve operation
The bypass valve of KS20S softener can be set in different
positions (see 7.2. Valve positions):
• Normal operation
• Bypass
• Diagnostic bypass
• Shut off.
Setting Mode

water hardness of 30 f°H and an average daily
consuption of 0,1 m3 waterper person.
Note! Honeywell recommendsto install a 100µ-
cartridge filter.

4.4. Sodium concentration limit
When operating a KS20S softener, the limit value for the
sodium concentration (acc. drinking water ordinance) of
200 mg/l may not be exceeded.
To reduce the water hardness by 1 °fH, add about 4,5 mg/l
sodiumtothewater.Additionally,takeintoaccountthebasic
sodium content of the raw water. The maximum possible
softening results from these values.

6. Installation Instructions
6.1. General advices
Location
When you choose the softener location, please take into
account the following parameters:
• Install the KS20S softener ina chosen place on a flat firm
and clean surface.
• The KS20S softener must beclose to a drain line to allow
an easy connection.
• Make sure there is an electrical earth grounded plug to
power the unit.
Pressure
A minimum pressure of 2 bar is needed to allow the valve to
regenerate properly.Please do not operate over 8 bars.
If this is the case, use a pressure reducer upstream of the
installation.
Power connection
Be sure that power cannot be switched off accidentally at
a wall switch. If the power cable is damaged, please ask a
professional electrician to change it.
Plumbing
Theplumbingmustbeingoodstate. Incaseofdoubt, please
change it. We advise the use of prefilter upstream the instal-
lation.
All plumbing for the water inlet, distribution and drain lines
shouldbe donecorrectlyinaccordancewiththelegislationin
forceatthetime oftheinstallation.Thepipesizeforthedrain
line should be a minimum of 20 mm (3/4’’).
To prepare for any maintenance:
1. Shut down water inlet
2. Unplug the KS20S softener
3. Drain the installation by opening the taps at the highest
and the lowest level of your house.
Water Temperature
6.2. Mounting
1. Thoroughly flush pipework.
2. Install the KS20S softener.
• Note flow direction (indicated by arrow).
• Install without tension or bending stresses.
3. Establish the connections to the KS20S softener.
4. Connect the sewerage tube to the discharge connection
(inner tube ø min. 13 mm, 1/2").
Caution! The installation must be performed by a
professional installer only.
Caution! It isseriously recommended to install apres-
sure reducer ahead of the softener, if the input pres-
sureis morethan6bar.Failingtoadheretothissafety
note can cause irreversible damage.
Caution! During cold weather, bring the softener to
room temperature before operation.
Caution!Duringhotweather,donotinstallthesoftener
in direct sunlight or in a room with a temperature
above 45°C.
Warning! All electrical and plumbing installations
should be performed by professional electricians and
installers in accordance with all local codes.
Caution!Finishallthesolderingonthemainplumbing
and on the drain, before connecting the softener.
Failing to adhere to this safety note can cause irrever-
sible damage to the KS20S.
Caution! Inlet water temperature must not exceed
35° C. Complete installation must not be allowed to
freeze. Failing to adhere to this safety note can cause
irreversible damage to the KS20S.
Caution! Finish all welding and soldering works in the
near vicinity to the softener before mounting.
Failing to adhere to this saftey note can cause irrever-
sible damage.
Caution! Make sure the seal is fitted properly!

The black lines represent the direction of water flow.
7. Start-up
7.1. Start-up instructions
1. Manually addwater in brine tankabove the aircheck
(around 10 liters)
Do not fill with salt at the moment.
2. Place the valves into the bypass position (see 7.2. Valve
positions).
3. Turn on the main water supply.
4. Open a cold water tap downstream of the KS20S
softener.LetthewaterrunafewminutesuntiltheKS20S
softenerisfreefromanyforeignmaterial(usuallysolder)
that may have resulted from the installation.
5. Once the softener is clean,close the water tap.
6. Switch on the power.
7. Push andholditdownfor3 seconds.Thesystem
will advance to the "first" position
8. When themotorstops,push repeatedly until the
display shows "RINSE".
9. Slowlyturn thebypassvalvetoclosetheoutletandopen
the system inlet.
10. Run water to the drain until it runs clear.
11. PlacetheKS20Ssoftenerinthebypassposition(system
inlet-outlet closed – full bypass).
12. Push until the KS20S softener is back in to
softening mode.
13. Once again, push and hold it down for
3 seconds.
14. Whenthemotorstops,push repeatedlyuntilthe
display shows "BACKWASH".
15. Slowly open the inlet bypass valve 1/2 way to feed the
softener with water. Allow water to slowly fill the tank.
16. When a solid stream of water starts coming out of the
drainline,opentheinletbypassvalvealltheway.Letthe
water drain until its clean.
17. Slowlyplacethebypassvalveinto"Normalposition"(see
7.2.Valvepositions)byopeningtheoutletsideofbypass
valve. Now the system inlet-outlet is open.
18. Push until the display shows "REGENERANT
DRAW DN" or "REGENERANT DRAW UP".
19. Carefully check the water level in the brine tank.
If it decreases, skip to the next step or see the section
“Troubleshooting” on page 19.
Caution! The start-up mustbe performed by a profes-
sional installer only.
Note! Once put under electrical power, the valve may
automaticallyrunacycleinordertogetintotheservice
position.Displaywill alternate betweeninstallername,
time of day, flow rate and remaining capacity.

20. Push again until the display shows "RINSE".
Allow the rinse cycle to run its full course.
21. Whiletherinsecycleisfinishing,loadbrinetankwithsalt.
22. If the refill cycle is at the end of the regeneration cycle,

tion.
23. Go to section “Programming - Advanced Installers” on

9. History
The KS20S softener saves the follwing parameters in cont-
roller history:
• Number of days since the last regeneration
• Salt consumtion since the last regenetation
• Salt consumption since start-up
• Total number of regenerations since start-up
• Reserve history
• Usage history
• Maximum flow rate in the last 7 days

Caution! Do not change the operation cycles or their
order.Anychangesoftheoperationcycleswillprevent
the device from functioning correctly.
Caution! Donotchangethecontrolvalvesfrom down-
flow to upflow brining or vice versa.
The valve bodies for downflow and upflow are unique
to the regeneration type and should not be interch-
anged. A mismatch of valve body and regeneration
piston will result in hard water bypass during service.
Note! Maximum number of digits to set is eleven.
Note! Maximum number of digits to set is eighteen.
