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.

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.
