III. DESCRIPTION AND PRINCIPLE OF OPERATION
The appliance consists of a body, flange at the bottom side (for water heaters
intended for vertical mounting) or at the sides (for water heaters intended for
horizontal mounting), protective plastic panel and a safety-return valve.
1. The housing consists of two steel tanks (water tanks) and a casing (outer
shell) with heat insulation between them from an environmentally clean high-
density polyurethane foam and a housing (outer shell) with thermal insulation
placed in-between made of ecologically clean high density polyurethane, and
two pipes with thread G½'' for cold water supply (marked by a blue ring) and hot
water outlet pipe (marked by a red ring).
The inner tanks are made of steel protected from corrosion by a special glass-
ceramic or enamel coating.
2. An electric heater and a magnesium protector are installed on each flange.
The electric heater is used for heating the water in the tank and is operated
by the thermostat, which automatically maintains the set temperature. The
appliance has two built-in devices (for each of the water tanks) for overheat
protection (thermo-switches) which switch off the respective heater from the
mains when the water temperature raises too much.
3. The safety-return valve prevents the appliance's complete emptying if the
cold water supply stops from the water mains. The valve protects the appliance
from pressure increases higher than the allowed value during heating mode
(an increase of temperature causes water expansion and therefore pressure
increase) by releasing the excess pressure through the drainage opening.
The safety-return valve cannot protect the appliance in the event of water mains
pressure that is higher than the pressure stated for the appliance.
MOUNTING AND SWITCHING ON
IV.
Attention! Improper installation and connection of the appliance will make it
hazardous with grave health consequences and may cause even death of users.
It may also damage their property, that of third parties, as a result of flooding,
explosion, fire. Installation, connection to the water mains and connection to power
lines must be carried out by qualified technicians. A qualified technician means a person
who has appropriate competencies pursuant to the regulations of the relevant state.
Mounting
1.
We recommend the device to be mounted in close proximity to locations where hot
water is used in order to reduce heat losses during transportation in the pipelines.
If the device is mounted in a bathroom, it should be in such a place so as not to be
poured with water from the showerhead or a portable showerhead attachment.
When mounted on a wall - the device is suspended by means of the M8 bolts attached
to the housing, which are installed on brackets pre-mounted and levelled with the
wall. The load-bearing brackets and dowels for wall mounting are included in the kit.
Vertical installation scheme - Fig. 4.1
Horizontal installation scheme – Fig. 4 2.
Depending on the installation method of the appliances (horizontal or vertical), you
can orient the TESY logo on the control panel according to the orientation of the
appliances. - Fig. 4 2.
In order to prevent injury to the user and/or third persons in the event of faults in
the system for hot water supply, the appliance must be installed in premises
with floor hydro insulation and drainage to the sewerage. Under no circumstances
should you place objects which are not waterproof under the appliance. If the
appliance is installed in premises without floor hydro insulation, a protective tub with
drainage to the sewerage must be in place under the appliance.
Note: The set does not include a protective tub and it should be chosen/
purchased by the user.
Connecting the water heater to the water supply system

the water mains higher than 0.6 MPa); 4 - stop valve; 5 - funnel connected to the
sewerage; 6 – hose; 7 – drain water tap.
Upon connecting the water heater to the water mains you must consider the
indicative colour markings (rings) affixed to the pipes: blue for cold (incoming)
water, red for hot (outgoing) water.
English
The mounting of the safety return-valve supplied with the water heater is
obligatory. The safety return-valve must be mounted on the cold water supply
pipe, in accordance with the direction of the arrow stamped on its body, indicating the
direction of the incoming water.
Exception: If the local regulations (norms) require the use of another protection
valve or device (which conforms to EN 1487 or EN 1489), then it must be
purchased additionally. For device operating in accordance with EN 1487 the declared
maximum operational pressure must be no more than 0.7 MPa. For other protection
valves, the pressure at which they are calibrated must be 0.1 MPa lower than the one
marked on the appliance's plate. In these cases the safety valve which the appliance is
supplied with should not be used.
Other type of stopping armature is not allowed between the protection return
valve (the protective device) and the appliance.
The presence of other (old) safety return-valves may lead to a breakdown of
your appliance and they must be removed.
The attaching of the safety return-valve to threads longer than 10 mm is not
allowed; otherwise this may damage the valve and therefore pose danger to
your appliance.
The safety-return valve and the pipe between the valve and the water heater
must be protected from freezing. In case of hose draining its free end must be
always open to the atmosphere (not to be immersed). Make sure that the hose is also
protected from freezing.
To fill the water heater with water first open the hot-water tap of the water-mixing
faucet. Then open the cold-water tap of the water-mixing faucet. The appliance is full
when a constant stream of water flows from the water-mixing faucet. Then close the
hot water tap.
When you have to empty the water heater, first you must cut off its power supply.
Then stop feeding water to the appliance. Open the hot-water tap of the water-
mixing faucet. Open tap 7 (fig. 5) in order to drain the water from water tank. If there
is no such tap built in the pipeline, than the water can be drained directly from the inlet
pipe of the water tank, having it disconnected from the water mains prior to this
When removing the flange, it is normal for several litres of water, which have remained
in the water tank, to be discharged.
Measures must be taken to prevent damages by the discharged water.
If the pressure in the water mains piping exceeds the value specified in paragraph II
above, a pressure-reducing valve must be installed, otherwise the water heater will
not be correctly operated. The manufacturer will not bear any liability for problems
arising from improper operation of the appliance.
3. Connecting the water heater to the electrical mains
Make sure the appliance is full of water before switching on the electrical power
supply.
3.1. For models with a power cord with a plug, connection to the electrical mains is
done by inserting the plug into an electrical socket.
Disconnection from the electrical mains is done by unplugging the power cord from
the socket.
The electrical socket must be properly connected to a separate current loop that
is provided with a safety fuse. It must be earthed.
3.2. Water heaters without power cord
The appliance has to be connected to a separate current loop of the stationary
electrical installation, provided with a safety fuse with nominal current of 16A
(20A for power > 3700W). Connection is done using copper single core (rigid)
conductors – cable 3 x 2.5 mm² for a total power of 3000W (cable 3 x 4.0 mm² for
power > 3700W).
In the electrical circuit providing power supply for the appliance there has
to an inbuilt device which would disconnect all poles in case of category III
overvoltage.
To install the power supply wire to the water heater, remove the plastic cover
(Fig.7.2).
Connect the power supply wire in compliance with the marking on the terminals,
as it follows:
•
the phase – to marking A or A1, L or L1;
•
the neutral – to marking N (B or B1 or N1);
•
The safety wire must be connected to the screw joint marked with
After installation, put the plastic cover back in its place!

ANTI-CORROSION PROTECTION – MAGNESIUM ANODE
V.
The magnesium anode provides additional protection to the water tank's inner
surface from corrosion. It is an element undergoing wear and tear and is subject
to periodic replacement, which is at the expense of the user. In view of the long-
term and accident-free use of your water heater, the manufacturer recommends
periodic inspections of the magnesium anode's condition by a qualified technician
and replacement whenever required, and this could be performed during the
appliance's technical preventive maintenance.
For replacements, please contact the authorized service centres or a qualified
technician!
