FIRST COMMISSIONING
Once the tank is connected to water supply system and power supply, and the safety valve tested
(accordingly with the manual attached to the valve), the tank can be put in operation.
Procedure:
a)
Check the water main and wiring; Check proper placement of thermostat sensors. The sensors must
be inserted all the way in; first the thermostat and then the safety fuse;
b)
Open the hot water valve on the combination faucet;
c)
Open the cold water inlet valve to the tank.
d)
When the water starts flowing through the hot water valve, the filling of the tank is finished
and the valve needs to be closed;
e)
If a flange lid leak is discovered, the flange lid bolts need to be tightened;
f)
Fasten the electric installation cover;
g)
When heating service water heating by electric energy, turn on the electricity (for combined tanks,
the heating water inlet to the heating insert must be closed);
h)
When heating the water with thermal energy from a hot water heating system, turn off the electricity
and open the valves at the inlet and outlet of heating water or bleed the exchanger.
i)
Once the operation restarts, keep flushing the tank until the cloud disappears.
j)
Make sure to fill in properly the warranty certificate.

TANK CLEANING AND ANODE ROD EXCHANGE
Repetitive water heating causes limestone sediment on both the enamelled tank walls and chiefly
the flange lid. Lime scale settling depends on hardness of heated water, its temperature and on the volume
of hot water used.
We recommend checking and cleaning the tank from scale and eventual replacement
of the anode rod after two years of operation.
The anode life is theoretically calculated for two years of operation; however, it changes with water hardness
and chemical composition in the place of use. Based on such an inspection, the next term of anode rod
exchange may be determined. Have a company in charge of service affairs deal with the cleaning and
exchanging of the anode. When draining water from the tank, the combination faucet valve for hot water
must be open, preventing the occurrence of under-pressure in the tank receptacle which would stop water
from draining.
To prevent the occurrence of bacteria (e.g. Legionella pneumophila) within stack heating
it is recommended, if absolutely necessary, to increase the temperature of hot service water
(HSW) periodically for a transitional period of time to at least 70°C. It is also possible to make
use of another way of disinfecting HSW.
