Checks
Water Softener: Check salt: Salt level should be checked regularly and the Wa-

Cycle: every two days
Dosing unit: Check Aqua-Plus: The Aqua-Plus level should be checked
regularly and the container replaced as appropriate.
Cycle: once a weeks
6.3.1 Installation Rail (pressure lost, pressure reducer filters)
The water softener's input pressure and output pressure (i.e. PerPur input pressure) can be
read at the two manometers. The difference indicates the pressure lost in the water sof-
tener, the filter of the pressure reducer and the two cartridge filters. If, as is assumed here,
the water softener is working properly, then this pressure difference just indicates the condi-
tion of the filters. The more material that these filters have filtered out, the greater the loss
of water pressure.
When this difference, or pressure loss, exceeds 0.9 bar (13.5psi), the filter of the pressure
reducer must be cleaned (1) and/or the filters (4, 5) must be replaced. In this case please
get in touch with your
Nortec Systems Customer Service.
Cycle: once a weeks
6.3.2 Storage Tank (initial pressure)
Valve where the pressure meatering device has to be connected.
The initial pressure of the storage tank can be checked with a pressure measuring device.
Then the tank must be completely empty. The pressure must be 0.7 bar (10 psi).
Cycle: every 6 months
