CAUTION! Before switching on the power supply, make sure that the EWH is filled with
water!
The water heater shall be grounded to ensure its safe operation.
The EWH is equipped with a regular power cord with or without a europlug and an residual current
device (optional). The electrical socket shall have a grounding terminal with a ground wire supplied to
it and be located in a place protected from moisture or meet the requirements not lower than IPX4.
It is important to constantly monitor the EWH after the initial powering. In case of any parameter
mismatch (heating, temperature, indication, thermostat failure), contact the maintenance depart-
ment.
Maintenance
Periodic maintenance and timely replacement of the magnesium anode are indispensable conditions
for the long-term operation of the EWH. Failure to comply with these requirements is the basis for
withdrawing the EWH from warranty service. Maintenance and replacement of the magnesium
anode are not included in the manufacturer's and the seller's warranty liabilities.
During maintenance, the check is performed with respect to the condition of the magnesium anode
and the presence of scale on the THE. Simultaneously, the sediment is removed, which may
accumulate at the bottom of the EWH.
The magnesium anode shall be replaced at least once a year. If water contains a large number of
chemical impurities, the magnesium anode shall be replaced every six months. The formation of
scale on the heating element may lead to its failure, which is not a warranty case, and its replacement
is not included in the manufacturer's and the seller's warranty liabilities.
If there is some scale on the heating element, it can be removed with the use of descaling agents or
mechanically. When removing sediment from the EWH, do not apply excessive force and use
abrasive cleaners to avoid damaging the protective coating of the inner tank.
The first maintenance procedure is particularly important, because the intensity of the formation of
scale and sediment and the consumption of magnesium anode serve as the grounds for determining
the timing of subsequent maintenance, which in turn provides an opportunity to extend the EWH life
cycle. If the above requirements are not fulfilled, the EWH life cycle is shortened, the probability of
EWH failure increases, and the warranty liabilities are terminated.
To carry out maintenance and replace the magnesium anode, one shall perform the following
steps:
џ
Power off the EWH;
џ
Allow hot water to cool down or use it through a mixer;
џ
Block the flow of cold water into the EWH;
џ
Unscrew the relief valve or open the drain valve;
џ
Put the rubber hose on the cold water inlet pipe or on the drain valve by directing its second end into
the sewage system;
џ
Open the hot water faucet on the mixer;
џ
Drain the water from the EWH through the cold water inlet or drain valve;
џ
Remove the protective cover, disconnect the wires, unscrew and remove the removable flange
from the casing;
