Connection to power supply
EN
Before connection of water heater to electric power supply make sure that its conditions correspond
to technical characteristics of water heater.
ATTENTION! Before connecting to the power supply, be sure that EWH is filled with
water!
The water heater has to be grounded for ensuring its safe work. The water heater is equipped
with regular power cord and euro-plug, and tripped breaker (option). The socket has to have a
ground contact with the grounding wire connected to it and shall be settled down in the place
protected from moisture, or meet the requirements not below IPX4.
Maintenance
The Maintenance (M) and timely replacement of the magnesium anode are the obligatory conditions
for long-term work of EWH. Non-performance of these requirements is the basis for removal from the
guarantee maintenance.
ATTENTION! Maintenance and replacement of the magnesium anode has to be carried
out at least once a year and don't enter warrantee certificates of the manufacturer and
the seller.
When carrying out the maintenance, the condition of the magnesium anode and the existence of a
scum on the electric heating element shall be checked. Along with it, the sediment which can be
collected in the lower part of EWH has to be removed. If the scum was formed on the electric heating
element, it can be removed by a scum removal means, or mechanically. During removal of sediment
from EWH it isn't necessary to apply excessive efforts and to use abrasive cleaners not to damage a
protective covering of an internal tank.
Importance of the first maintenance is that it is possible to determine the terms of carrying out the next
maintenance by intensity of scaling and deposit, an expense of the magnesium anode and, as a
result, to prolong operation terms. At non-performance of the mentioned above requirements
operation term is reduced, the probability of EWH breakdown increases and the warrantee certificate
is terminated.
For carrying out maintenance and replacement of the magnesium anode it is necessary to
execute the following:
Disconnect EWH power supply.
џ
Wait till hot water becomes cool or spend it via a sink mixer.
џ
Block the entry of cold water in EWH.
џ
Unscrew the safety valve or open the drain valve.
џ
Put on a rubber hose on water inlet or on a drain valve, directing its second end to the sewerage.
џ
Open hot water tap on a sink mixer.
џ
Drain the water from EWH using water inlet or a drain valve.
џ
Remove the protective cover, disconnect wires, unscrew and take out the removable flange from
џ
the case.
Replace the magnesium anode, clean the electric heating element out of sediment or lime, if
џ
necessary, and remove a deposit.
Assemble, fill EWH with water and connect to the power supply.
