for mounting an additional heating element. Such version is used when the heater is connected to either a solar system
or a system with a heat pump, to heat water in the upper part of the heater to the temperature required. The insulation of
the heater consists of a 100 mm polyurethane foam without CFCs content. The tank shell is made of painted steel sheet;
connecting parts are metal-coated.

IMPORTANT NOTICES
-
Without a confirmation of both electric installation and assembly being performed by an authorised company,
the warranty certificate is invalid.
-
Check and exchange the Mg anode regularly.
-
No stop valves can be put between the heater and the safety valve.
-
All hot water outputs must have a combination faucet.
-
Before filling the heater with water for the first time, it is recommended to fasten the flange connection nuts of the
tank.
-
It is not allowed to handle the thermostat, aside from temperature resetting with a control button.
-
All electric installation handling, setting, and regulation feature exchange, may only be implemented by a service
company.
-
The thermal fuse must not be turned off!
In case of thermostat defect, the thermal fuse interrupts electric power
input to the heating element if the water temperature in the heater exceeds 90 °C.
-
As an exception, the thermal fuse may also switch off due to water overheating caused by overheating the hot water
heating system boiler (in case of a combined heater).
-
We recommend you operate the heater with one type of energy.
In case a solar system is connected to the bottom
exchanger, it is necessary to connect a TJ 6/4" line element in the coupling above the heater for potential additional
heating.

PUTTING THE HEATER INTO OPERATION
After connecting a heater to the water main, the hot water heating system, the electric network, and after testing its
safety valve (based on the valve manual attached), the heater may be put into operation.
Procedure:
a)
Check both water and electric installation; for combined heaters, check the installation to a hot water heating
system. Check proper placement of operating and safety 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 heater;
d)
when the water starts flowing through the hot water valve, the filling of the heater is finished and the valve
needs to be closed;
e)
if there is a leakage in the flange lid, we recommend fastening the flange lid bolts;
f)
fasten the electric installation cover;
g)
when heating service water heating by electric energy, turn on the electricity (for combined heaters, the heating
water inlet to the heating insert must be closed);
h)
when heating service water with electric energy from the hot water heating system, turn the electricity off and
open the valves of heating water input and output, possibly de-aerate the exchanger. When commencing
operation, flush the heater until the cloudiness in the water is gone.
