2. .The safety return valve must be mounted on the cold water supply pipe, in observance of the direction arrow stamped on its body, indicating the incoming water’s direction. Additional stopcocks must not be mounted between the safety return valve and the water heater. Exception: If the local regulations (norms) require the usage of another protection valve or mechanism (in accordance with EN 1487 or EN 1489), then it must be bought additionally. For mechanisms operating in accordance with EN 1487, the announced 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 sign. In these cases, the safety valve which the appliance is supplied with should not be used.
3. The safety valve and the pipe between the valve and the water heater must be protected from freezing. During 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.
4. In order to secure the water heater’s safe operation, the safety return valve must undergo regular cleaning and inspections for normal functioning /the valve must not be obstructed/, and for the regions with highly calcareous water, it must be cleaned from the accumulated limescale. This service is not provided under warranty maintenance.
5. In order to prevent injury to users and third persons in the event of faults in the system for providing hot water, the appliance must be mounted in premises outfitted with floor hydro insulation and plumbing drainage. Don’t place objects, which are not waterproof under the appliance under any circumstances. In the event of mounting the appliance in premises not outfitted with floor hydro insulation, a protective tub with plumbing drainage must be placed under the appliance.
6. During operation ­ regime of heating, the water ­ water drops through the drainage opening of the protection valve are usual. The protection valve should be left open to the atmosphere. Measures should be taken to lead and collect the leakages in order to prevent damages.
7. If the probability exists for the premise’s temperature to fall below 0°, the water heater must be drained. In the event you must empty the water heater, first, you must cut off its power supply.

DESCRIPTION AND PRINCIPLE OF OPERATION

The appliance is designed to operate in regions where the water hardness is not more than 10°dH. In case it is installed in a region where the water is harder it is possible that limestone precipitation accumulates very fast. This can cause a specific noise during heating, as well as fast damaging of the electrical part. For regions with harder water yearly cleaning of the limestone precipitation in the appliance is recommended, as well as usage of not more than 2 kW of heating power The appliance consists of a body, flange, plastic control panel, and safety return valve.

1. The body consists of a steel reservoir (water tank) and plastic housing (outer shell) with thermal insulation placed in-between, and two pipes with thread G ½“, for cold water supply (marked with a blue ring) and hot water discharge(marked with a red ring). The inner reservoir is made of steel proved against corrosion by a special glass-ceramic coating

2. The flange is fitted with an electric heater and magnesium anode protector. The flange is fixed to the water tank with bolts.
   The electric heater heats the water in the tank and is controlled by the thermostat, which automatically maintains the preset temperature.
   The plastic control panel incorporates a switch (depending on model), an adjustable thermostat (depending on model), and thermal cut-out and control lamps.
   The thermal cut-out is a device, which switches the heater off the power supply when the water temperature reaches excessive values. If this device is actuated, you should call a service station.
   The signal lamps (depending on the model) on the control panel indicate the current model of the unit.
   The magnesium protector provides additional anti-corrosion protection to the internal tank for heaters fitted with glass-ceramic coating.

3. The safety-return valve prevents the appliance’s complete emptying in the event of a cold water supply interruption. The valve protects the appliance from pressure increases higher than the allowed value during heating (! pressure will increase when temperature increases), by releasing the excess pressure through the drain outlet. Water dropping out through the drains during the warming process is a normal event that must be taken into consideration when the boiler is installed.
   ATTENTION! The safety-return valve cannot protect the appliance in the event of water mains pressure in excess of the acceptable pressure stated for the appliance.

INSTALLATION AND SWITCH ON

Attention! Improper installation and connection of the appliance may make it hazardous for the health and life of consumers. It may cause grievous and permanent consequences, including but not limited to physical injuries and/or death. Improper installation and connection of the appliance may also lead to damage to the consumers’ property /damage and/ or destruction/, or to that of third persons, as a result of, but not limited to flooding, explosion, and/or fire. Installation, connection to the main water and power supply, and putting into operation must be carried out by certified electricians and technical personnel certified in the installation of this category of appliances, who have obtained their license in the state where the installation and commissioning of the appliance are carried out, and in compliance with its local legislation.

Installation

We recommend the installation of the device at close proximity to locations where hot water is used, in order to reduce heat losses during water transportation. The selected location must exclude the possibility of water spray originating from the showerhead or other water contacts.

• Appliances designed for installation above sinks are assembled in such a manner that the outlet/inlet pipes are pointed downwards (to the floor of the premise).
  The appliance is affixed to a wall by means of mounting brackets attached to the unit’s body. Two hooks are used to fix the appliance (min. Ø 4 mm) firmly on the wall (included in the mounting set).

• Appliances designed for installation under sinks are assembled in such a manner that the outlet/inlet pipes are pointed upwards (to the ceiling of the premise).
  The appliances can be placed standing on the floor or mounted on the wall. In case you want to mount the appliance on the wall, the suspension must be done with two hooks (min. Ø 4 mm) securely attached to the wall.

IMPORTANT: The type of appliance designed to be installed UNDER / ABOVE a sink is marked on the appliance.
The bearing plank construction for boilers installed above / under sinks is universal and allows the space between hooks to vary between 96 and 114mm. (fig.2).
For a clear understanding of wall installation schemes, please refer to fig.2 (A above sink, B under sink, and C for floor installation).
ATTENTION! In order to prevent injury to user and third persons in the event of faults in the hot water supply system, the appliance must be mounted in premises outfitted with floor hydro insulation and sewer drainage. Don’t place objects, which are not waterproof under the appliance under any circumstances. In the event of mounting the appliance in premises without floor hydro insulation, a protective tank with a sewer discharge drainage must be placed under the appliance.
Notice: the set does not include a protective tub and the user must select the same.

The mounting of the safety return valve supplied with the water heater is obligatory. The safety return valve must be installed on the cold water supply pipe, according to
the arrow stamped on its body indicates the supplied water direction.
Exception: If the local regulations (norms) require the usage of another protection valve or mechanism (in accordance with EN 1487 or EN 1489), then it must be bought additionally. For mechanisms operating in accordance with EN 1487, the announced 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 sign. In these cases, the safety valve which the appliance is supplied with should not be used.
ATTENTION! Another type of stopping armature is not allowed between the protection return valve (the protective device) and the appliance.
ATTENTION! Any other /old/ safety return valves may lead to a failure of your appliance, therefore they must be removed.
ATTENTION! Fixing the safety return valve to threads longer than 10 mm is not allowed, as it could damage the valve and could make the use of your appliance dangerous.
ATTENTION! The safety valve and the pipe between the valve and the water heater must be protected from freezing. During 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.

The boiler is filled with water by opening the tap on the cold water supply system and the tap on the hot water mixing faucet. After the filling process is complete, a constant
stream of water should flow from the water-mixing faucet. Now you can shut the hot water tap on the mixing faucet. When you must empty the water heater, you should first cut it off the power supply.

OPERATING THE DEVICE

Before the initial start of the device, please make sure that the water heater has been correctly connected to the electrical network and that it is filled up with water. Switching on the water heater is done through the device incorporated in the installation, which is described in the subitem
3.2 of paragraph V, or by inserting the plug into an electrical socket (for models with a cord with a plug).
Clarification to Fig.6: Operation modes:

1. Position ( ) anti-freezing mode
   WARNING: The electrical power supply of the device should be switched on. The safety valve and the pipe connecting it to the device must be secured against freezing.

2. Position ( ) maximum temperature

3. Position ( ) at this mode the water temperature reaches about 60°С. In this way, heat losses are reduced.

4. Light indicator – at heating mode, it is lit in red, and it is lit in blue when the water has been heated up and the thermostat has switched off.

5. Regulator knob – for temperature setting

Water heaters with the electrical-mechanical POP-UP operation:

1. Push the knob to pop-up Fig. 7а.
2. Set the temperature of the water heater Fig. 7b This setting allows for gradual temperature adjustment.
3. Push the knob to retract Fig. 7c

WARNING! Once a month set the knob to the position ‘maximum temperature’ for a period of 24 hours (unless the device is constantly operated in this mode). Thus you will ensure better hygiene of the heated water.

RUST PROTECTION MAGNESIUM ANODE

The magnesium anode protects the water tank’s inner surface from corrosion. The anode element is an element undergoing wear and tear and is subject to periodic replacement. This is the cost for 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 stations!

PERIODIC MAINTENANCE

Under normal use of the heater, under the influence of high temperature, limescale /the so-called limescale layer/ is deposited upon the heating element’s surface. This worsens
the heat exchange between the heating element and water. The heating element’s surface temperature increases along /with boiling water/. The thermoregulator begins to switch on and off more frequently. A ‘’deceptive” activation of the thermal protection is possible. Due to these facts, the manufacturer recommends preventive maintenance of your water heater every two years by an authorized service center or service base. This protective maintenance must include cleaning and inspection of the anode protector (for water heaters with glass-ceramic coating), which shall be replaced with a new one if the need arises.
In order to clean the appliances use a damp cloth. Do not clean with abrasive or solvent content detergents. Do not pour water over the appliance.
The manufacturer does not bear the responsibility for all consequences caused by not obeying the instructions, given hereby.
Environmental protection instructions.
Old electric appliances contain precious materials and must not be disposed of with domestic waste! Please make your active contribution to the protection of the environment and dispose of the appliance in the stations organized for the purpose (if available).
