General Valve Installation
Water Pressure
20 – 70 psi (1.5 – 5bar)
Electrical Supply
Uninterrupted AC
Existing Plumbing
Free of any deposits or build-ups inside pipes
Softener Location
Locate close to drain and connect according to local
plumbing regulations
Bypass Valve
Always provide for a bypass valve if unit is not
equipped with one
CAUTION
•Do not exceed 120psi (8.3 bar)
•Do not exceed 43°C (110°F)
•
Do not subject the unit to freezing conditions
Planning the installation
Locate the softener tank and brine
tank close to a drain where the system
will be installed. The surface should be
clean and level.
Perform all plumbing according to local
plumbing codes.
Use a ½” minimum pipe or tubing size
for the drain line.
Flexible drain line should be limited to
2 metres.
Any solder joints near the valve must
be done before connecting any piping
to the valve. Always leave at least 6”
(152 mm) between the valve and joints
when soldering pipes that are
connected to the valve. Failure to do
this could cause damage to the valve.
Electrical connection
With the power off, connect the transformer - supplied - to a continuous electrical supply. Push the flying
lead from the transformer into the adaptor on the lead coming from the controller.
Obtain your water hardness
Run hard water for approx. 1 minute and rinse the test tube well.
Fill the test tube up to the 10ml level. Add 2 drops of the dark solution and mix gently. If the water sample
contains hardness it will turn red.
Add the dark solution in batches of 5 drops, holding the dropper bottle 45 degrees.

5
Mix gently after each 5 drops.
Count the drops needed until the colour of the sample in the test tube changes from a dark red to a dark
blue/green.
You need this figure for when SET WATER HARDNESS (step XX)
Setting the electronic controller
Turn on power and the softener display will say WELCOME.
The Display is a 2 line display showing both the Model No and
also Time and Hardness. The Time and Hardness will alternate
every 10 seconds.
To finalise commissioning of the softener, you need to set
both Time (24hr clock in hours and minutes) and the water
hardness as determined by the amount of drops in your water hardness test.
Setting the time of day
Wait until display shows Time of Day.
If Time of Day is correct, skip to ‘SET HARDNESS’.
Press Up button to show flashing Hours. Please note it is a 24hr clock.
Press Up or Down button to set Hours.
Press @ to confirm Hours.
After confirming Hours with (), display will show minutes flashing.
Use Up and Down button to set Minutes.
Press @ to confirm Minutes.
Set water hardness
Wait until display changes to Hardness.
Press ‘Up’ Button to show Set Hardness with no flashing.
Use ‘Up’ Button to set number as determined by your water hardness test.
Press @ to confirm setting.
Flush the softener
Add water until there is approximately 1” (25mm) of water above the grid plate. If the tank does not have a
grid, add water until it is above the air check in the brine tank. Do not add salt to the brine tank at this time.
If the unit has a bypass valve, place it in the bypass position.
Slowly turn on the main water supply.
Open a cold soft water tap nearby and let water run a few minutes or until the system is free of foreign
material resulting from the plumbing work. Close the water tap when water runs clean.
Place the bypass in the service position and let water flow into the salt tank. When water flow stops, slowly
open a cold water tap nearby and let water run until air is purged from the unit. Then close the tap.

6
Option – Monarch Rapid-Fit Bypass
The Monarch Rapid-Fit Bypass is available ¾” and 1” mbsp.
The Rapid-Fit also has 3/8” connections for both hard and soft water tee points.
It features a 1” high flow check valve built into the body to comply with local water authority guidelines,
giving a service flow rate of 80 lpm.
Order reference:
BYPASS34 (3/4” mbsp)
BYPASS44 (1” mbsp)

7
Converting Domestic models to Horeca models
Connect to power supply and turn on
Display will show WELCOME then change to alternate between Time and Hardness. If required Model No
not shown, progress to below.
Press Scroll button and hold for 10 seconds. Display will change to System Settings
Press ‘Up’ arrow within 10 seconds of display saying System Settings and display will change to flashing
display Set Date, time, etc
Values within display will flash. These can be adjusted by Up and Down keys, but do not need adjusting.
Press Scroll button repeatedly until display advances to:
NOTE: Flashing text is correct text.
Press ‘Up’ arrow to change display to ON
Press Scroll button and display changes to EXIT
Press ‘Up’ button to confirm Exit. Display will revert back to alternating display
To convert to Time, Hardness with Days Override – CS Models
Display will show WELCOME then change to alternate every 10 seconds between Time, Hardness and
Override
Press ‘Up’ + ‘Down’ buttons together for 5 seconds to enter Factory Settings. Display will change to Valve
Settings & 85HE Up-flow.
Press Scroll button repeatedly until Company Label shows in display.
Go down list by using ‘Down' button until model number is highlighted. In case of CS100 HE only, use ‘Up’
button. Press Scroll button to confirm. Display will change to Salt Efficiency
Press Scroll button and hold for 3 seconds. Display will return to alternating display where new model
number will be shown, plus Time, Hardness and Override will change every 10 seconds.
Programming is complete. Disconnect power

7 Flow to drain
continuously
7.1 Valve settings incorrect Check valve settings
7.2 Foreign material in control valve.
Remove piston assembly and inspect
bore. Remove foreign material and
check control in various regeneration
positions
7.3 Internal control leak.
Replace seals, spacers, and piston
assembly.
7.4 Control valve jammed in
backwash, brine or rinse position Replace piston and seals and spacers
7.5 Timer motor stopped or jammed
teeth
Replace timer motor and check all
gears for missing teeth
7.6 Timer not operating properly Replace timer
7.7 Piston is stuck in position. Motor
may have failed or gears have jammed
or disengaged
Check for power to motor. Check for
loose wire. Check for jammed gears or
gears
disengaged. Replace faulty
parts.

12
8 Softener fails to
regenerate
8.1 Electrical service to unit has been
interrupted
Assure permanent electrical service
(check fuse, plug, chain or switch)
Check / reset time of day
8.2 Controller is not operating properly Replace controller
8.3 Defective valve drive motor
Replace drive motor
8.4 Improper programming Check programming, reset as needed
9 Iron in softened
water
9.1 Iron content exceeds
recommended parameters Add iron removal pre-filter system
9.2 Fouled resin bed
Check backwash, brine draw and brine
tank fill. Increase
frequency of
regeneration. Increase backwash time
Ensure softener does not regenerate at
the same time the iron filter
backwashes.
10 Salt water in
service line
10.1 Plugged injector system Clean injector and replace screen
10.2 Timer not operating properly Replace timer
10.3 Foreign material in brine valve Clean or replace brine valve
10.4 Foreign material in brine line flow
control
Clean brine line flow control
10.5 Low water pressure
Raise water pressure
10.6 Improper programming Check programming, reset as needed
11 Softener fails to
draw brine
11.1 Drain line flow control is plugged Clean drain line flow control
11.2 Injector is plugged Clean or replace injectors
11.3 Injector screen is plugged Replace screen
11.4 Line pressure is too low
Increase line pressure (line pressure
must be at least 20 psi at all times)
11.5 Internal control leak
Replace seals and spacers and/or
piston assembly
11.6 Improper programming Check programming, reset as needed

13
11.7 Timer not operating properly Replace timer
11.8 Insufficient rinse time See above and all points under #5
12 Main PCB not
working
12.1 No power
Check electrical service and
transformer.
12.2 PCB has failed
Replace PCB
13
Drain flow
restrictor jammed
sideways in the
valve
13.1 Wrong assembly direction
Change the direction of DLFC
14 Corroded PCB and
ribbon cable
14.1 Too long refill duration, salt water
go into the board of the PCB
Replace PCB
15 Unit running out of
capacity
15.1 Blending valve is opened
Close blending valve

Check whether the motor is working or
not, and then check the PCB (replace
a new PCB), then check whether the
piston and gears are stuck / blocked or
not (change piston/gears).
