6 - Installation and Commissioning
Installation must meet valid rules and may be done only by qualified staff.
Defects caused by improper installation, use or handling are not covered by warranty.
After the tank is installed and connected to an existing heating system, it is recommended to clean the entire heating
system using a suitable cleaning agent, e.g. MR-501/R.
Anti-corrosion protective liquid should be also used, e.g. MR-501/F.
6.1 - Connection to heat sources
Place the tank on the floor and level it. Fit the insulation, see Installing Insulation on the Tank. Connect the heating system
according to the diagram of recommended connection - see Chap. 5. Install a drain valve at the lowest point of the tank.
Install an air vent valve at the highest point of the system. Insulate all the connection piping.
6.2 - Connection to water mains
DHW piping shall be done according to valid rules. The connections to the tank including the location of components is
shown in the recommended connection diagram in chapter 5. Installation of a pressure reducing valve on the tank inlet is
recommended. For water mains pressure above 6 bar a pressure reducing valve is necessary. To prevent water loss, we
recommend installing an expansion vessel at the cold water inlet with a minimum volume of 4% of the total volume of water
in the DHW piping, including heat exchangers, circulation pipes, etc. (usually 8 l). Should the water be too hard, install a
water softener before the tank. In case the water contains mechanical impurities, install a filter.
6.3 - Commissioning
The tank shall be filled up together with the heating system, respecting valid standards and rules. In order to minimize
corrosion, special additives for heating systems should be used. The quality of heating water depends on the quality of
filling water at commissioning, on the top-up water and on the frequency of topping up. This has a strong influence on the
lifetime of heating systems. Poor quality of heating water may cause problems like corrosion or incrustation, esp. on heat
transfer surfaces.
Quality of DHW shall meet the conditions shown in the Table of limit values for total dissolved solids in hot water
on this page.
Fill the heating circuits with the appropriate fluids and air-bleed the entire system. Check all connections for leaks and verify
the system pressure. Set the heating controller in compliance with the documentation and manufacturer’s recommendations.
Check regularly the proper function of all control and adjustment elements.

7 - Installing Insulation on the Tank
Product description
Thermal insulation is a part of thermal stores, preventing heat loss. For easier handling, the insulation shall not be fitted
on the tank until it reaches its definite place of installation.
Warning
Insulation installation shall be done in two persons. Do not use any tools for installation. Keep away from open fire.
Installing Insulation
1. Fix the tank following installation instructions.
2. Wrap the insulation around the tank carefully. Check that the insulation adheres to its body perfectly. This can be
reached by rubbing and patting the insulation by hand from its center evenly in both directions until the insulation
adheres to the tank’s surface completely and no bubbles are left.
3. Use the holes for connections as a rest during the insulation installation.
4. At least one person presses the insulation to the tank, pulling both ends together. The other person closes the
insulation lock from the side.
5. Put on the upper insulation and cover.
6. Push on the covering plastic rosettes depending on the size of connections.
7. Finish the tank installation in compliance with the respective instructions and valid standards and rules.
Warranty on insulation
□ Warranty shall become null and void if:
○
the procedure described in the Installation Manual was not respected
○
the product was used for other purposes than intended.
□ Warranty does not cover:
○
usual wear and tear,
○
damage caused by fire, water, electricity or a natural disaster,
