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 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.

**** All alterations and modifications to the water heater’s construction and electrical circuitry are forbidden. If such alterations or modifications are established during inspection, the appliance’s warranty shall be null and void. Alterations and modifications shall mean each instances of removal of elements incorporated by the manufacturer, building in of additional components into the water heater, replacement of elements by similar elements unapproved by the manufacturer.

Mounting

1. The water heater must only be mounted in premises with normal fire resistance. 2. In the event the device is mounted in a bathroom, the selected location must exclude the possibility of water spray contact from the showerhead or portable showerhead attachment.
2. The water heater is designed to operate only in closed and heated premises where the temperature is not lower than 4°C and it is not designed to operate in a continuous protracted regime.
3. The appliance is affixed to a wall via the mounting brackets attached to the unit’s body (if the brackets are not attached to the unit’s body, they must be affixed in place via the provided bolts).

Water heater connection

1. The appliance is intended to supply hot water to household sites equipped with a piping system working at pressure below 6 bar (0,6 Mpa).

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 lime scale. This service is not provided under warranty maintenance.

5. In order to prevent injury to user 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 a 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°С, the water heater must be drained. In the event you must empty the water heater, first you must cut off its power supply. The inflow of water from the water mains must first be terminated and the hot water tap of the mixing-faucet must be opened. The water tap 7 (fig 3)
   
   
   
   must be opened to drain the water from water tank. If there is no such tap build in the pipe line, than the water can be drain directly from inlet pipe of water tank after when you disconnect it from water main.

8. These instructions shall also apply to water heaters equipped with a heat exchanger – Section VII. These are appliances with inbuilt heat exchanger and are intended to be connected to the heating system with maximum temperature of the heat carrier of 80°C.

Connection to the electrical network

1. Do not switch on the water heater unless you established it was filled with water.. 2. Upon connecting the water heater to the electric mains care must be taken to connect the safety lead. 3. Models without power cord, the circuit has to be supplied with a safety fuse (16A) and with inbuilt device to ensure disconnection of all pole pieces in the conditions of over-voltage from category III. 4. If the power supply cord (of models that have one) is damaged, it must be replaced by a service representative or a person with similar qualification, to avoid any risk.
2. For water heaters intended for horizontal mounting the power supply conductor insulation from fixed wiring must be protected from direct contact with the flange (in zone under the plastic panel). For example, insulating sleeving having temperature rating higher than 90 °C can be used.
3. During the heating the appliance could produce a hissing noise (the boiling water). This is common and does not indicate any damage. The noise gets higher with the time and the reason for this is the accumulation of limestone. To remove the noise the appliance must be cleaned from limestone. This type of cleaning is not covered by the warranty.

Dear Clients,
The TESY team would like to congratulate you on your new purchase. We hope that your new appliance shall bring more comfort to your home.

DESCRIPTION AND PRINCIPLE OF WORK

The appliance is designed to operate in regions where the water hardness is not more than 10°dH. In case that it is installed in a region where the water is harder it is possible that limestone precipitation accumulate 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 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 safety-return valve.

1. The body consists of a steel reservoir (water tank) and housing (outer shell) with thermal insulation placed in-between made of ecologically clean high density polyurethane foam, and two pipes with thread G ½ ‘’ for cold water supply (marked by a blue ring) and hot water outlet pipe (marked by a red ring).
   The inner tank may be of two types depending on the model:

   • Made of steel protected form corrosion by a special glass-ceramics coating
   • Made of stainless steel
     The vertical water heaters may be outfitted with a built in heat exchange unit (serpentine tube). The heat exchenger’s entrance and exit are located at the sides and represent pipes with thread G ¾ ‘’.

2. The flange is outfitted with: electric heater and thermostat. The water heaters with glass-ceramics coating are outfitted with a magnesium protector. The electric heater is used for heating the water in the tank and is managed by the thermostat, which automatically maintains the set temperature. The thermostat has a built in overheating safety device, which switches of power to the heater when the water temperature reaches excessive values.

3. The safety-return valve prevents the appliance’s complete emptying in the event the cold water supply is interrupted. The valve protects the appliance from pressure increases higher than the allowed value during heating (! pressure increases upon an increase of temperature), via release of excess pressure during the drainage opening.

**** 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.

MOUNTING AND SWITCHING 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 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.

Notice: The installation of the unit is at the buyer’s expense.

1. Mounting
   We recommend the mounting of the device at close proximity to locations where hot water is used, in order to reduce heat losses during transportation. In the event the device is mounted in a bathroom, the selected location must exclude the possibility of water spray contact from the showerhead or portable showerhead attachment. The appliance is affixed to a wall via the mounting brackets attached to the unit’s body (if the brackets are not attached to the unit’s body, they must be affixed in place via the provided bolts). Two hooks are used for suspending the appliance (min. Ø 10 mm) set firmly in the wall (not included in the mounting set). The mounting bracket’s construction designed for water heaters intended for vertical mounting is universal and allows a distance between the hooks of 220 to 310 mm (fig. 1a, 1b, 1c).
