The
water heater connections for the in-flowing and out-flowing water are colour-coded. The
connection for the
supply of cold water is coloured blue, while the hot water outlet is coloured
red.
The
water heater may be connected to
the
water supply
in
two
ways. The closed-circuit
pressure system enables several points
of
use, while the open-circuit gravity system enables
a single point
of
use only. The mixer taps must also be purchased in accordance with the
selected installation mode.
The
open-circuit gravity system requires
the
installation of a non-return valve
in
order to
prevent the water from draining out
of
the
tank
in the event
of
the water supply running
dry
or being shut down.
This
installation mode requires
the
use
of
an instantaneous mixer tap.
As
the
heating of water expands its volume, this causes the tap to drip.
The
dripping cannot
be stopped
by
tightening it further; on
the
contrary,
the
tightening can only damage
the
tap.
The
closed-circuit pressure system requires
the
use of pressure mixer taps. For safety
reasons the
supply pipe must be fitted with a return safety valve
or
alternatively, a valve
of
the
safety class that prevents
the
pressure
in
the
tank
from exceeding the nominal pressure
by more than
0.1
MPa. The outlet opening on the relief valve must be equipped with an outlet
for atmospheric pressure.
The
heating
of
water
in
the
heater causes the pressure
in
the
tank
to increase
to
the level set
by the safety
valve.
As
the water cannot return to
the
water supply system, this can result
in
the
dripping from the outlet of
the
safety valve.
The
drip can be piped
to
the drain by installing
a catching unit just
below
the safety valve.
The
drain installed below
the
safety valve outlet
must be piped down vertically and located
in
the
environment
that
is free from
the
onset
of
freezing conditions.
In case the existing plumbing does not enable you to pipe
the
dripping water from the return
safety
valve into the drain, you can avoid the dripping by installing a 3-litre expansion
tank
on the inlet water pipe
of
the boiler.
In
order to provide correct operation of
the
relief valve, periodical inspections of
the
relief
valve
must be carried
out
by the user.
To
check the valve, you should open the outlet
of
the
return safety
valve by turning the handle
or
unscrewing
the
nut
of
the
valve (depending on
the
type of the valve).
The
valve is operating properly if the water comes
out
of the nozzle
when the outlet is open.

Between the water heater and return safety valve no closing valve may be built-in
because with it the function of return safety valve wou
Id
be impeded.
The water heater may be connected to the water network
in
the house without reduction
valve if the pressure
in
the network is lower than 0.5 MPa
(5
bar). If the pressure exceeds
0.5 MPa (5 bar), a reduction valve must be installed. Prior
to
the electric connection the
water heater must
obligatorily be filled with water. By first filling the tap for the hot water upon
the mixing tap must be opened. When the heater is
filled with water, the water starts
to
run
through the
outlet pipe of the mixing tap.
CONNECTION OF THE WATER HEATER
TO
THE ELECTRIC NETWORK
Before connecting to power supply network, install a power supply cord
in
the water heater,
with a min. diameter of 1,5 mm
2
(H05VV-F 3G 1,5 mm
2
).
For it the protection plate must be
removed from the water heater.
The connection of water heater
to
the electric network must be performed according to
standards for
electric installation. Install a disconnect switch (separating all poles from the
power
supply network) between the water heater and the permanent power connection,
in
compliance with
the
national regulations.

OPERATION AND MAINTENANCE
After connecting to water and power supply, the heater is prepared for use.
The water heater features
an
that enables
of
water temperature of
in
water heater tank. The
electronic regulator allows manual adjustment of temperature
in
range from 35°C to 75°C,
settings
to
cost saving operation mode and temperature adjustment
to
prevent freezing.
Electronic regulator display shows the current temperature
of
water
in
water heater.
OPERATION CONTROL:
The heater is switched ON and OFF by pressing the
~
key for 2s.
Continue pressing the
@ key and select the three operating modes:
-
~protection
against freezing (factory water temperature set
to
7°C)
e cost saving operation (factory set
to
55°C)
-

the
water
heater is not in use
for
longer periods
of
time, it should be protected
from
freezing
by
setting the temperature
to"*".
Do
not
disconnect the power.
Thus
the temperature
of
water
is
maintained
at
about
10°C. Should you choose
to
disconnect the power, the
water
heater should be
thoroughly
drained before the
onset
of
freezing conditions.
Water
is
discharged from heater
via
the inlet pipe. To this purpose, a special fitting (T-fitting)
must
be
mounted between
the
relief valve and the heater inlet pipe, or a discharge tap.
The
heater
can be discharged directly through
the
relief valve,
by
rotating
the
handle or
the
rotating
valve
cap
to
same position
as
for checking the operation. Before discharge,
make
sure
the
heater is disconnected
from
the
power
supply
, open the hot
water
on
the
connected
mixer tap. After discharging through the
inlet pipe,
there
is still
some
water
left
in
the
water
heater.
The
remaining water
will
be discharged after removing the heating flange, through
the
heating flange opening.
The
external parts
of
the water heater
may
be cleaned with a mild detergent solution. Do not
use
solvents and abrasives.
Regular preventive maintenance inspections ensure faultless performance and long
life
of
your heater.
The
first
of
these
inspections should be carried
out
by
the authorised
maintenance service provider
about
two
years
from
installation
in
order
to
inspect the
wear
of
the protective anticorrosion anode and remove the lime coating and sediment
as
required.
The
lime coating and sediment on the
walls
of
the
tank
and on
the
heating
element
is a product
of
quality, puantity and temperature
of
water
flowing through the
water
heater.
The
maintenance service provider shall also issue a condition report and recommend the
approximate date
of
the
next inspection.
Never
try
to repair
any
possible faults
of
the
water
heater by yourself, but inform
about it the nearest authorised service workshop.
