2.8 INSPECTION, MAINTENANCE & CARE FOR THE APPLIANCE
During the heating process the water that increases its volume during the heating must drip
off the safety valve outlet (in non-pressurised connection this water drips off the
combination faucet valve). In full heating (about 65
3% of the tank capacity. The function of the safety valve has to be checked regularly (based
on the information contained in the attached safety valve manual). In common operation,
such a check needs to be implemented at least once a month, and after each appliance
shutdown that exceeds 5 days.
Caution! In doing so, the cold water supply pipe and the connection fitting of the tank may
get heated! If the hot appliance does not work, or if hot water is not withdrawn, no water
shall drip off the safety valve. If water drips, then the pressure in the supply piping is
either too high, or the safety valve is defective. Please call a specialised plumber
immediately!
If water contains too many minerals, an expert has to come to remove the scale that forms
inside the tank, as well as free sediments. Repetitive water heating causes limestone
sediment on both the tank walls and chiefly the flange lid. The sedimentation depends on
the hardness of water heated, its temperature, and amount of hot water consumed.
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 the company in charge of service affairs clean and
exchange the anode.
When discharging water from the appliance, the combination faucet valve for hot water
must be open in order to avoid creating under pressure that would prevent water discharge.
This has to be performed after one or two years of operation. The cleaning is carried out
through the hole in the flange by: draining the boiler, dismantling the flange lid and cleaning
the tank. A new sealing has to be used for re-fitting. Since the inside of the vessel has special
enamel, the surface of which must not get in contact with a scale removing agent - do not
work with a lime pump. Remove the lime layer with a timber and suck it off, or wipe it off
with a clout. After that, the appliance must be rinsed thoroughly and the heating process is
checked the same as during the initial putting in operation. Do not use any abrasive cleaning
agents or dye thinners to clean the outer shell of the appliance (such as cellulose thinner,
trichlor, and the like). For cleaning use a wet clout and add a few drops of liquid cleaning
agent for household applications.
