Valve Display
Your CalSoft unit has been pre-programmed for a water hardness level of 300ppm. Under normal
operating conditions these settings do not require any adjustment but if they are required to be
adjusted please contact your installer or Calmag.
If the electricity fails, the electronic controller will keep in the memory the pre-set program.
Use the up and down arrows to set the correct time of day.
If you need to manually initiate a regeneration, please see section “PROGRAMMING” in the manual.
Operating Tips
• Keep the bypass closed at all times.
Open the bypass to service the water softener
and to allow hard water to service.
•Keep the salt level at all times above the
water in the brine tank.
Installation
Water pressure
A minimum of 1.5 bar inlet water pressure is required for the valve to operate effectively.
Do not exceed 5 bar. If the pressure is higher t a pressure reducing valve. Note:- It is recommended
that a pressure reducing valve rated at 5 bar should be tted on the valve inlet.
Electrical connection
A standard UK power supply is required to operate the unit.
Bypass
Always provide a bypass valve for the installation.
Water temperature
Water temperature is not to exceed 43°C. The unit cannot be subjected to freezing conditions.
Both will invalidate any guarantees.

2. Installation guidelines

Manual Regeneration
Press and hold the key ‘ ’ for 3 seconds to unlock keys.
In stand-by position, you can press and hold the key ‘ ’ for 5 seconds whereby the valve will
go into the manual regeneration interface:
(1) If you choose ‘DELAY’ and press key ‘ ’ to exit, the valve will regenerate in the next
REGEN. TIME (default is 2am).
Note: The regeneration mode “METER IMMEDIATE” has no ‘DELAY’ choice.
(2) If you choose ‘IMMEDIATE’ and press key ‘ ’ to exit, the valve will regenerate immediately.
When regeneration has started, the screen will display:
“BACKWASHING” starts ashing. When the valve reaches “BACKWASH” position, “BACKWASHING”
will stop ashing. Vertical bars will decrease on the regeneration cycle. Pressing any key will
automatically advance the valve to the next cycle position: ie BRINE, Screen will display:
The valve will advance to the remainder of the regeneration cycle (RINSE and FULL)
as per the above steps.

Installation and start up procedure
1. Turn off the mains water supply to the house by closing the stopcock. Then drain the
pipe by opening the kitchen tap.
2. Cut the pipe after the stopcock and install the inlet, outlet and bypass valves. To comply
with regulations a check valve must be installed between the stopcock and the softener.
3. Connect a hose between the softener inlet and the inlet valve, then connect a hose between
the softener outlet and the outlet valve.
4. Turn off the inlet, outlet and bypass valves.
5. The drinking water tap connection and the garden tap connection should be made
in the pipe between the stopcock and the bypass valve.
6. Run the drain tube to the nearest waste pipe, typically a washing machine type standpipe.
Cut off any excess tube. Secure the pipe so that it cannot fall out of the standpipe. Ensure
that it is installed with an air gap of 20mm.
7. Push the overow hose onto the overow connection on the back of the cabinet and run it
downhill to the outside of the house, keep the hose as short as possible.
8. Open the mains stopcock then the inlet, outlet and bypass valves. Open the kitchen sink tap
for a few minutes to remove all the air and any colour from the water, and then close the tap.
Leave for 10 minutes, checking for leaks. Close bypass valve.
9. Plug the valve into an approved power source. Once powered, it is possible that the valve
drives itself to the service position.
10. Set the time of day using the “PROGRAMMING” section of the manual.
11. Fill approximately 7 litres of water above the bottom of the salt bucket.
12. Start a manual regeneration using the “PROGRAMMING” section of the manual:
This will begin the regeneration cycle and allows the CalSoft to determine the correct water
level in the cabinet. This process will take approximately 35 minutes.
13. After the regeneration cycle has completed salt can be added into the salt bucket at the
front of the cabinet. The amount of salt is not critical apart from that there should always
be 3-4kg in the bucket to accommodate at least one regeneration.

Bypass Assembly
The bypass valve is provided with various functions such as bypass and water hardness adjustment.
Different angles of bypass knob have different functions (see below). The larger angle (value A),
the higher water hardness in hardness adjustment position.

7. Further Information

Advice from various international bodies state that when a water softener has been installed then a
separate unsoftened water tap should be provided - mainly for drinking water purposes. This would
normally be at the kitchen sink as this would ordinarily be the main area that people would pour drinking
water from and also used for cooking purposes. Alternative positions for this supply, or more than one
supply can be installed, and is purely down to the individual application. The separate unsoftened
drinking tap should then be connected into the supply pipe prior to the bypass valve and then run directly
to the specied drinking tap. See illustration below.
The Regulations state that “All premises supplied with water for domestic purposes shall have at least
one tap conveniently situated for the drawing of drinking water”. Drinking water must also comply with
the Regulations which stipulate a maximum limit of 200ppm for sodium. The Department of Health
recommends that this sodium level should not be exceeded for baby food preparation and also for
individuals that may be on a low sodium diet.
As the maximum limit is set at 200ppm,it is therefore necessary to check if this would be exceeded in the
area and could be the case where the water is extremely hard. This level of sodium would be exceeded
if the incoming water hardness reaches 425ppm (assuming that the incoming level of sodium is zero
from the mains supply). This can be checked with the Calmag water hardness test kit or alternatively by
asking the local water supplier the level of hardness
and sodium in the area . Once this information is
conrmed then a balanced decision can be made for
the requirements of a water lter or not.
Replacement lters...
Contaminants are trapped within the lter cartridge, therefore you need
to change them on a regular basis to maintain a clean water supply.
The lifespan of a cartridge is dependent on the quality of water passing
through it and we recommend changing lter cartridges every 4-6 months.
