3.2 Cables and other supporting materials required for installation and external connection are not supplied.
4. Safety
4.1 This TSEFB model takes into account the international level of protection from the dangers caused by the
electrical, mechanical, thermal effects, possible ignition or radiation during normal operating conditions according to
the instructions.
4.2 It is forbidden to carry out maintenance and repair of TSEFB connected to the power supply circuit. In accordance
with the installation rules, the circuit breaker (see Table 1) must be installed in the fixed wiring, which is guaranteed
to provide a single action off all poles from the mains.
4.3 Before energising TSEFB, check it for any damage that threaten lives and health, and also check the integrity of the
grounding conductor and reliability of its contact with the ground terminal. Check the serviceability of the mains and
its voltage.
4.4 Attention! Do not turn on TSEFB if not filled with water, closed valves (no water circulation) and in the case of
possible freezing of water in the heating system and TSEFB. Do not use water from the heating system for food and
household needs.
4.5 To avoid violations of the strength and integrity of the heating system and TSEFB with a possible increase of the
internal pressure, it is imperative to install the pressure-limiting safety valve to the heating system in a convenient
place for the user when installing TSEFB (included in the package). If the feed water pressure is above 3.0 bar, the
feeding line must have a reducer.
4.6 It is strictly forbidden to establish isolation valves between TSEFB and the security group (expansion tank, safety
valve, air valve, etc.).
4.7 Do not leave operating TSEFB unattended for a long time.
4.8 Attention! To prevent accidents, all work on the installation, connection, repair and maintenance of TSEFB must
perform only qualified professionals who have the competence and authority for their conduct.
5. Design and Operation Principle
5.1 TSEFB consists of individual nodes placed in steel parallelepiped housing (see Figure 2). The housing perceives
stress, which occurs during operation and transportation.
5.2 TSEFB basic elements: a tank - steel rectangular container, thermally insulated on the outer surface with steel
pipes (threaded) for connecting the heat carrier to the tank and draining it into the heating system with installed THE;
power light, temperature controller; drainage system; heating switches; a thermomanometer, a circulation pump. The
tank has a biased-off thermoswitch limiting heating temperature in the anomalous mode. After sufficient cooling,
heating switches automatically. For assembly work and visual inspection, remove the front cover. To audit or
replacement parts using the drainage system coolant is drained from the boiler.
5.3 The TSEFB principle of operation is as follows. Cold water is pumped through the lower tube in the tank, where it
is heated by the THE and enters the heating system through the top outlet pipe. The thermostat, the handle of which
is located on the front panel, sets the supply water temperature. The desired temperature is maintained automatically
with a deviation within the band (4 - 8) °C. Electricity consumption economy mode is selected using the "Heating"
key and the thermostat handle.

6. Preparing for Operation and Operation Order
6.1 TSEFB wall installation, connection to the heating system and testing should be performed by qualified personnel
in compliance with the requirements of the project and all the installation and operation rules. Before connecting TSEFB,
thoroughly rinse away any dirt from the heating system.
ATTENTION!
Protective connection to Earth required.
Check all wiring connections including factory connections before switching on.
Water must be treated with the correct concentration of inhibitor.
Failure to follow these instructions will void the product warranty.
Forced circulation of water through TSEFB provides a circulation pump.
The heating system (see Figure 1) must have the pressure relief valve (Pmax = 1.5 Pnom = 3 bar).
ATTENTION! Lack of pressure relief valve and damage during installation can lead to failure of the boiler
under abnormal operating conditions.
6.2 Remove the front panel by unscrewing the mounting screws, place TSEFB on the wall vertically in the prepared
place and outline two metal mounting anchor bolts (mounting holes shown in Fig. 2).
Pushing TSEFB aside, drill in the wall 8 mm holes per marking to a depth of at least 35 mm, put into the holes anchor
bolts and secure them by spreading out the metal collet (tightening the nut).
Before final installation, check the load bearing capacity of bolts and wall (taking into account the weight of TSEFB
with water). Set TSEFB on anchor bolts and secure with lock nuts M6 through spring washers.
Connect TSEFB to the heating system, connect the power cable with the grounding conductor in accordance with the
marking (F, N, PE/A, B, C, PE). Conduct an external inspection of parts to identify and resolve problems.
6.3 After verifying that the heat carrier is in the heating system and the integrity of the system, turn TSEFB on in the
following order: Set the thermostat handle to the position that corresponds to the maximum temperature (turn fully
clockwise), check voltage and turn on the opening line circuit breaker supplying power to TSEFB (the housing network
lamp lights up) and consistently (at intervals of 3-5 s) push key of heating mode switches: 1, 2, 3. This enables THE,
and the water warms up. Check the heating and circulation of the carrier.
6.4 The flow temperature on the thermometer is set by a handle of thermo-controller and corresponding heating stage
key. Subsequent operation of TSEFB is in automatic mode, and the desired temperature is maintained constant with
possible deviations within the band (4 - 8) °C.
6.5 To turn TSEFB off, it is necessary to turn the thermostat knob counter-clockwise until it stops (position
corresponding to tmin), disable "Heating" keys and in (3 - 5) min the automatic circuit breaker in the fixed wiring.
7. Maintenance
7.1 Prior to commissioning, as well as two hours after the start and periodically, at least once a month, you need to
check the reliability of fastening of wires, cables, tightening of threaded connections. If necessary, tighten
connections, avoiding damage that affect the subsequent use of TSEFB.
7.2 A company that performs installation and maintenance of TSEFB must be experienced, trained or licensed to
perform this work.
7.3 Servicing TSEFB is allowed to persons who have studied the operating principle, structure, mode of operation,
and have been instructed in safety and got admission to perform this type of work.
7.4 For the operation of apparatus and components of a heated system without damage due to deposits of scale and
sludge or corrosion of metal, the circulating water and feed water used should be suitably treated. Indicators of water
quality must meet the following requirements: the total hardness less than 20 uEg/kg, the contents of mechanical
impurities and suspended particles in the water are not allowed. Ways to treat water, which guarantees the fulfilment
of these requirements must be selected by the owner or specialised organization (project or maintenance).
7.5 Periodically check the operation of the safety valve, i.e., check water drain at least 1 time in 6 months.

8. Storage
8.1 Before operating, TSEFB must be placed indoors in packaged form. Room temperature 5 °C - 40 °C, relative
humidity 60% at 20 °C. The indoor air should not have aggressive and flammable vapours and gases.
8.2 Keep unwrapped TSEFB at repair stations only for the period of repair.
8.3 TSEFBs must be transported in closed vehicles (cars, containers, wagons, and the like).
8.4 Ambient temperature during transportation: from minus 10 to plus 50 °C, relative humidity 60% at 20 °C.
8.5 Packaging and apparatus after use shall be delivered to wastepaper and scrap metal stations.
