6 - Installation and Commissioning
Installation shall meet valid rules and may be done only by qualified staff. The tank shall be placed on the floor,
as close to the heat source as possible.
Warning: Defects caused by improper installation, use or handling are not covered by warranty.
6.1 - Connection to heat sources
Connect heating circuits to the inlet and outlet of the heating coil. The heat source connects to the tank using G
3/4” fittings.
6.2 - Connection to water mains
DHW piping shall be made according to valid rules. G 3/4” fittings are used to connect the tank to a cold water
inlet and hot water outlet. A safety kit (code 17387) shall be installed at the cold water inlet. Installation of
a reducing valve to the tank inlet is recommended. If the pressure from water mains exceeds 6 bar, a reducing
valve is necessary. An 8-liter expansion tank shall be installed at the cold water inlet.
Should the water be too hard, install a water softener before the tank. In case the water contains mechanical
impurities, install a strainer.
There is a drain valve at the lowest point of the tank.
Complete DHW piping shall be properly insulated.
6.3 - Electronic anode rod installation
Magnesium anode rod is factory installed in the tank. An electronic anode rod (code 13793) can be installed in
the tank instead of the magnesium one.
6.4 - Commissioning
Earth the tank before commissioning.
The earthing screw is located at the marked place. Fill the entire
system with liquids and air-vent. Check all connections for leaks and a system pressure.
The quality of top-up and heating water is set by ČSN 07 7401:1992.
Hot water quality must meet the conditions
shown in the Table of limit values for total dissolved solids in hot water, page 7 of this Manual.
It is recommended to maintain the temperature of the hot water in the tank, e.g. by means of a heat pump, in the
temperature range of 48-52 °C. It is recommended to temporarily raise the temperature of the entire hot water
system to 65-70 °C as a protection against the formation of bacteria, especially Legionella. It is recommended
to carry out a temporary temperature increase whenever the hot water supply is shut down for a longer time.
Requirements for the quality and temperature of hot water can be set by a special regulation according to the
methods of hot water use (staff hygiene, hot water for hospitals, educational institutes, technological water,
etc.). Set the parameters of the respective controller according to the manufacturer‘s documentation and
recommendations. Check regularly that all control and adjustment elements are functioning properly.
