entire cold water supply piping. It is therefore advisable to drain all fittings and piping that
carry water, up to the part where the house water meter is installed (connection of the house
to water main) which is not jeopardised by frost. When the tank is to be used again, it has to
be filled with water and one needs to make sure that the water flowing out at the hot water
valves did not contain any bubbles.
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
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 heater 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 If the hot water heater does not work, or if hot water is not withdrawn, no water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. This has to be performed after one or two years
of operation. Repeated heating causes lime scale settling on the receptacle walls and mostly
on the lid of the flange. 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 discharging water from the heater, the mixing valve battery for hot water must be open
in order to avoid creating underpressure that would prevent water discharge. 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 heater
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 heater (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.
