EWH shall be operated in closed heated spaces and is not designed for continuous flowing mode.

Main technical characteristics

The manufacturer reserves the right to make changes to the design and specifications of the heater without prior notice.

Information on place of marking and method of determining of the date of manufacture:

Date of manufacture is coded with a unique serial number on the identification plate (sticker), located at the bottom of the casing. Serial number of the product consists of thirteen digits. The third and fourth digits of the serial number are year of manufacture, the fifth and sixth – month of manufacture, the seventh and eighth – date of EWH manufacture.

Description and principle of operation

• EWH consists of casing, tubular electric heater, relief valve and protective cover.
• The outer casing of EWH consists of steel tank heat insulated with impact-resistant plastic and two threaded pipes for cold water inlet (with blue ring) and hot water outlet (with red ring). Inner tank has a special glass-porcelain coating reliably protecting the inner surface against chemical corrosion.
• Tubular electric heater (TEH) (7), thermostat (8) and magnesium anode (9) are mounted on the removable flange. TEH is used to heat water and thermostat provides with possibility of heating temperature regulation up to +74° c (± 5° C). Magnesium anode is designed to neutralize effects of electrochemical corrosion on the inner tank.
• Water temperature adjustment in the inner tank is made by thermostat control unit (10), located on the protective cover of the water heater. The thermostat also has temperature switch – safety-protection device against EWH overheating, which disconnects TEH from power supply when water temperature exceeds +93° C (± 5° C). In the course of operation EWH casing can heat.
• Actuation of water heater thermal protection is not a malfunction. Return of water heater to operating condition is made by pressing thermal switch rod, located under EWH protective cover (fig.
• Relief valve performs functions of return valve, preventing the ingress of water from water heater into water supply in cases of pressure drop in the latter and in cases of pressure increase in the tank when strong heating of water, as well as function of safety valve, relieving excess pressure in the tank when strong heating of water.
• Backlight power selection key (11) is EWH operating mode indicator Figure. 1: lighted up when heating water and turn off when water temperature reaches the set.
• There is residual current device (RCD) (option) mounted on the EWH electric cord which provides EWH disconnection from power supply when current leakage to grounded EWH elements.

Installation and connection

All installation, plumbing and electrical works must be performed by qualified personnel.

Arrangement and installation

EWH installation shall be performed in accordance with marking on the housing and the following table:

It is recommended to install EWH as close as possible to the place of hot water using to reduce heat loss in the pipes. Depending on the model you will require 2 or 4 anchors.

• When choosing the place of installation total weight of EWH filled with water shall be taken into account. Walls and floor with low carrying capacity should be strengthened accordingly. When drilling (making) holes in the wall, regard is to be had to cables, ducts and pipes in the wall. EWH is suspended with casing on anchor hooks fixed in the wall.
• Hooks mounting on the wall shall exclude spontaneous movement of EWH brackets along them. To perform maintenance and servicing of EWH the distance from the protective cover to the nearest surface in the direction of removable flange axis shall be at least 0,5 m.
• In order to avoid damage of the user’s and/or third parties’ property in the event of a faulty hot water system, it is required to install EWH in spaces with waterproofing and drainage to the sewers, and in no case to place under items exposed to the water under EWH. When placed in unprotected areas a protective plate (not supplied) with drainage into sewers shall be installed under the EWH.
• In case of placing EWH in hard-to-reach places in order to perform maintenance and warranty service (mezzanine floors, niches, ceiling voids, etc.), installation and dismantling of EWH is carried out by the user on his own or for his own account.

Connection to water supply

Cold water shall be supplied to EWH using pre-filter with water treatment level not less than 200 µm.

• Install pressure relief valve (17) at the cold water inlet (21) tube with the blue ring, with 3,5 – 4 revolution, ensuring junction tightness with any sealing material (flax, FUM tape, etc.).
• During water heater operation water may leak out of the exhaust outlet pipe of the safety valve to relieve excessive pressure, which is made for the purpose of water heater safety. This outlet pipe shall remain open to the atmosphere and be installed constantly down and in a non-freezing environment. It is recommended to attach to the drain hole a rubber or silicone tubing of appropriate diameter to drain moisture. It is required regularly (at least once a month) to discharge a small amount of water through the exhaust pipe of the safety valve into the drain to remove lime deposits and to test the operating functionality of the valve.
• Knob (18) is intended to open the valve (17). It is required to control when operating water heater this knob to be in position closing water draining from the tank.
• Connection to water supply system shall be made in accordance with (Figure 1) using copper, plastic pipes or special sanitary flexible conduits designed for temperature up to 100° C at the maximum working pressure. Do not use used flexible pipes. Plumbing pipes and fittings shall conform to the parameters of the water supply network and have the required quality certificates.
• Excessive efforts are not allowed when mounting in order to avoid damage to pipe threads, glass-porcelain coating of inner tank.

ATTENTION! Do not operate EWH without safety valve or valves made by other manufacturers.

After having connected EWH make sure that cold water shut-off valve in EWH (24) is open and hot water shut-off valve in EWH (25) is closed. Open the EWH cold water inlet valve (22), hot water inlet valve (23) and hot water mixer faucet to allow outflow of air from EWH. When complete filling of EWH, water will constantly flow from tap faucet. Close the hot water tap on faucet mixer, check the flange for leaks and, if necessary, tighten the bolts. When connecting EWH in places not provided with water mains it is allowed to supply water to EWH from auxiliary tank using pumping station, or from the tank placed at a height of not less than 5 meters from the top of EWH.

Connection to power supply

Before connecting of water heater to power supply, make sure that its settings correspond to specifications of the heater.

ATTENTION! Before switching on power supply, make sure that EWH is filled with water!
Water heater shall be earthed to ensure its safe operation.
Water heater is equipped with a standard power cord with euro plug and RCD (option). Power outlet shall have grounding contact with earthing wire and be in a place protected from moisture, or meet requirements not less than IPX4.

Operation and maintenance

Control panel has power selection keys (11) Fig. 1 with integrated indicators.

Both keys correspond to power 2.5 kW. You can select heat level, basing on needs in volume of hot water, or depending on the season.
In the course of EWH operation user can adjust heating water temperature using temperature adjustment knob (10) Fig. 1 located on the protective cover. By turning the knob anticlockwise (up to the stop) EWH is disconnected from the power, by turning in a clockwise direction the temperature slowly increases up to +74° c (± 5° C).
Maintenance and timely replacement of magnesium anode are obligatory conditions for long-term operation of EWH. Failure to comply with these requirements is grounds for release from the warranty service.
ATTENTION! Maintenance and replacement of magnesium anode shall be made at least once a year and are not covered by the warranty of the manufacturer and the seller.
When performing maintenance, condition of magnesium anode and scale on TÈH are checked. At the same time residue that may accumulate in the bottom of the EWH is removed.

The magnesium anode must be replaced at least once a year. If water contains high levels of chemical contaminants, the magnesium anode must be replaced more often. Scaling at TEH can result in its malfunction, that is not a warranty case, and its replacement is not included in the warranty of the manufacturer and the seller.

If there is scale on TEH, then it can be removed by using scale removing means or mechanically. When removing residuals from EWH do not apply excessive force and do not use abrasive cleaners not to damage the protective coating of the inner tank.
The importance of the first maintenance is that by intensity of scale and residues, magnesium anode consumption terms for next maintenance services can be decided and, consequently, service life can be extended. In case of non- observance of the above requirements, EWH service life reduces, increases the probability of EWH breakdown and the validity of warranty expires.

To perform maintenance and replace magnesium anode follow steps:

• Turn off EWH power.
• Cool hot water or discharge it through the mixer.
• Cut off supply of cold water into EWH.
• Put a rubber hose on the cold water supply inlet pipe or discharge valve and direct the second end to the drain.
• Unscrew the relief valve or open drain valve.
• Open a hot water faucet on the mixer.
• Drain water from the EWH through cold water supply inlet pipe or discharge valve.
• Remove the protective cover, disconnect wires, unscrew and remove from the casing the removable flange.
• Replace the magnesium anode, clean the TEH if necessary from scale and remove residue.
• To assemble, fill EWH with water and power on.

When conducting EWH maintenance by forces of special organizations the appropriate mark shall be made in the warranty card. When replacing the magnesium anode independently by the consumer magnesium anode purchase receipt shall be attached to the present manual.

Specifying security measures

Electrical safety and corrosion protection of EWH are guaranteed only if there is an effective earthing in accordance with applicable electric installation rules and regulations.

When installing and operating EWH the following is not allowed:

• To power EWH if EWH is not filled with water.
• To remove the protective cover when the power is on.
• Use EWH without grounding or use water pipes as grounding.
• To connect EWH to water supply with pressure exceeding 0,6 MPa. (If pressure in the supply line is more than 0.6 MPa, an appropriate pressure reducing valve shall be installed at cold water inlet ahead of safety valve (not supplied) to reduce water pressure to normal). Installation of pressure reducing valve between EWH and relief valve is forbidden.
• To connect EWH to the water supply without safety valve.
• To drain water from EWH with power switched on.
