this system is configured to perform optimally at an operating
pressure of 3 bar (±½ bar); in case of a lower or higher
operating pressure the performance may be affected
negatively!

check water pressure regularly.

take into account that night time water pressure may be
considerably higher than day time water pressure.

install a pressure reducer ahead of the water softener if
necessary.

OPERATING TEMPERATURE: min. 2 / max. 48 °C

do not install the water softener in an environment where
high ambient temperatures (e.g. unvented boiler house) or
freezing temperatures can occur.

the water softener cannot be exposed to outdoor elements,
such as direct sunlight or atmospheric precipitation.

do not install the water softener too close to a water heater;
keep at least 3 m of piping between the outlet of the water
softener and the inlet of the water heater; water heaters can
sometimes transmit heat back down the cold pipe into the
control valve; always install a check valve at the outlet of the
water softener.

this water softener only works on 24VAC; it is equipped with a
230/24V-50Hz transformer; always use it in combination with

make sure to plug the transformer into a power outlet, which
is installed in a dry location, with the proper rating and over-
current protection.
