Commissioning The Softener
Put approximately 5 litres of water into the brine tank. You may also at this point put a
quantity of salt into the tank. Do not allow the salt level in the brine tank to exceed the
height of the overflow. You should keep the salt level above the water level and check the
salt level on a regular basis until a usage pattern has been established.
Programming The Valve
When the softener is first plugged in the valve type will display (F79) then a few seconds
later show the time setting screen. Use the up and down arrows to set the time and then
press confirm (all settings except time of day are pre-programmed but should be
adjusted where suitable, such as water hardness).
Capacity Settings
The capacity will have a default setting based on 300ppm hardness. If you wish to
change this, please follow these instructions. Using the up and down buttons, scroll to
‘Advanced Settings’ and Press CONFIRM. Scroll down to ‘Set Residual Water’ and press
CONFIRM. This will show you the total amount of treated water the softener can achieve
before regeneration. For reference the Cyan has a resin capacity of 12.5 litres.
If you need to change capacity settings, follow this calculation:
“Resin Capacity” x 50 ÷ “Water Hardness In PPM”
Example (12.5 x 50) ÷ 300 = 2.08m³
Regeneration
With the softener fully plumbed in and the valve programmed, final commissioning can
now start. When the softener is fully functional the regeneration will happen at the pre-
set time (see programming the valve in case of memory loss section below).
To initiate an immediate regeneration press and hold the RETURN button until the valve
motor starts to turn. If during a regeneration cycle you need to skip through the cycle,
this can be done in the following way. To skip to the next stage press the RETURN
button and this will take it to the next stage of the regeneration, this can be repeated to
get to the end of the regeneration cycle.
