C. Checking hydraulic fittings at installation site
Tap water pressure
In order for the water softener to
function properly the pressure in the
water supply network must not be
lower than 1.4 bar and higher than 8.0
bars. If water pressure is below the
former, pressure raising pressure tank
must be used; if water pressure
exceeds the maximum value,
pressure regulator (pressure reducing
valve) must be installed.
Important notice!
If during daytime water pressure is
high it is very likely that during night
D. Selecting installation site for the device
The water softener should be
located as close as possible to
hydrophore (in case of supplying
water from private well [intake]) or
water meter measuring the whole
water in the household (in case of
supplying the household with tap
water). The device should be
located in the immediate vicinity of
the outlet drain (floor drain, stub
pipe, laundry tub).
Installing the device upstream
from water heater (or boiler
unit), make sure that the
temperature of water at the
connection point does not exceed
0

C. It is recommended that a
back - pressure valve is fitted
between the water softener and the
water heater (or boiler unit) in order
to prevent hot water backflow to the
water softener. Too hot water may
cause damage of control valve
elements as well as the ion-
exchange resin.
E. Materials
Before commencing installation of the device, it is
important to check relevant connection of inflow
and outflow of water to the water softener. Water
"inflow" connection is located on the right side of
6
time it will exceed the maximum value
of 8.0 bars. In such case pressure
regulator (pressure reducing valve) is
recommended. It is recommended to
fit pressure gauges on the installation,
in accordance with the schematic
diagram (figure 1), in order to control
operating water pressure in the
installation.
Water flow rate
In order for the water softener to
function properly the minimum water
flow rate at the water inlet should be
11.0 litres per minute.
Make sure that the valve for water
used outside of the house (such as
water used for garden watering) is
installed upstream from the water
softener. Softening water that will be
used outside of the house is not cost
effective (unless necessary).
Installation site of the water softener
must be prevented from being
exposed to freezing. If frozen, the
water softener will be damaged.
Any damage resulting from freezing
is not covered by the warranty.
The water softener is powered with
24 V. Direct plug - in transformer
and power cable are provided along
with the device. Earthed power
socket for the water softener should
be located within the immediate
vicinity of the device and should be
protected against rain and subzero
temperatures. The water must be
always connected to the power
supply source; the power socket
must not be fitted with a controller
that could be incidentally switched
off.
