• Screw on the nuts 4 which are delivered with the appliances

ATTENTION! In order to prevent injury to user and/or 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 (or) plumbing drainage.

MOUNTING OF “SOFT” PU INSULATION (800-2000L)
For the installation of insulating material two persons, in the case of very big boiler, three persons are needed. The temperature of the room where the fitting takes place should be at least 18°C. The insulation set should be stored at above mentioned temperature at least one hour before operating!
In the next step both sides of the zipper have to be pulled with light traction into the direction of the arrows shown in FIG.11. Please take care that the prefabricated holes stay in place and the connections are accessible all the time.
It is important to make sure that both sides of the zipper do not remain more than 20mm apart from each other after being fitted (Fig.11). Now push both sides of the zipper to the boiler and fix them on the first position. If necessary, the insulation can be narrowed (Fig.11) down again.

Once the insulation material has been fitted correctly and fastened with the zipper, the foamed material is inlayed and closed with a plastic lid on the top. Finally, rosettes can be fixed onto the connections (Fig.11).
The insulating set should only be stored in a dry place! We cannot be held responsible for damage because of failure to observe these instructions!

CONNECTING THE SYSTEM TO THE MAIN WATER SUPPLY NETWORK

IMPORTANT! Connecting the waterheater to the main water supply network should be fulfilled in compliance with a project created by a hvac designer!
A Presence of WRITTEN DOCUMENT for additional components is required for warranty recognition! Only qualified technicians must install this device!

Installation of the storage tank with two heat exchangers should be done in accordance with Fig.7; Fig.12. Models without heat exchangers – the same as for models with one or two heat exchangers. Parallel installation acc. to Fig.9.

OBLIGATORY elements of installations are:

•  Inlet pipe.
• Main water tap.
• Pressure regulator. When pressure in the mains is over 6 bars it is required. In this case, the set pressure is according to the calculations of the designer, but should be not higher than 0.5 MPa! When pressure in the mains is under 6 bar, its presence is strongly recommended. In all cases the presence of a pressure regulator set at 0.4 MPa is important for the proper functioning of your device!
• Non-return valve. Its type should be defined by HVAC designer according to the local and European lows, standards and technical norms. Safety valve. Use only safety valves inside supplied kit. For schemes different than 7, 8, 9,12 or 13, safety valve must be defined by HVAC designer and have to be in accordance with the local and European lows, standards and technical norms.(Pnr = 0.8 МРа; EN 1489:2000). Valve dimensions acc. to Table.4

• Mandatory inlet pressure control with external expansion vessel!
  Max. inlet pressure of mains water u – 0.6 MPa
  IMPORTANT: Between the storage tank and safety valve there must not be any kind of stop valves or taps!
  IMPORTANT: The presence of other /old/ safety valves may lead to a breakdown of your appliance and they must be removed.

  • Safety valve drainage pipe. Must be implemented in accordance with the local and European lows, standards and technical norms. It must have sufficient slope for water runoff. Both ends should be open to the atmosphere and to be secured against frost. Take safety measures against burning when safety valve is open!. Fig.10 a, b, c.

  • Water heater drainage.

  • Drainage tap.

  • Hose.

  • Expansion vessel. In the storage tank there is no volume to accommodate the expansion of water due to its heating. The presence of the expansion vessel is obligatory in order not to lose water through the pressure relief valve! Its volume and type must be defined by HVAC designer and have to be in accordance with the system technical requirements, local and European lows, standards and technical norms. Its installation shall be carried out by a qualified technician in accordance with its operating instructions. Reference data on the volume of expansion vessel could be found in Table 5.
