4.4. Recommendations for optimal use
Central heating
For optimal use of the boiler and electric power
consumption, we recommend the use of quality room
thermostat connected to the boiler.
Daily temperature should be between 20°C i 22°C (for each
degree above 22°C the consumed energy is increasing
exponentially).
For the night operation we recommend temperature
between 15 i 17 °C. In this way energy saving is higher than
in case of complete turning off the boiler during the night.
If there is no room thermostat, for night operation the
temperature in boiler should be decreased to about 40°C or
turned off completely (9. main switch).
In summer period, valves below boiler should not be
closed (closing valves disables water circulation in
system (10 – 15 seconds) generated by safety
thermostat.
Warm water
Optimal temperature of sanitary water, in boiler, is 42°C up
to 45°C (above 48°C it comes to increased lime separation
that sticks to the
exchanger
, tubes and pump and may lead
to gradual decrease of boiler effect).
5. Maintenance
We recommend the inspection of a device once a year by
the authorized service (before heating season). This service
is not included in the guarantee. During the inspection all
electric and water connections should be tightened, the
system should be vented and – if necessary – filled up,
valves and general functionality of the device should be
checked.
If you notice a reduced effect of warm water it is necessary
to remove lime accumulated within the plate exchanger (1).
Only authorized service engineer can do removing lime.
Prior to the beginning of cleaning, valves (2) separating
the boiler from the sanitary water installation, should be
closed.
Cleaning tubes should be connected to the foreseen 1/2"
piping (3) (internal thread).
Cleaning solution (5) may be formic acid 2-3%, nitric acid 3-
4% or acetic acid 10%.
The solution should circulate through the system by a pump
(4), as long as there is the sludge in the outlet pipe.
Thereupon the direction of a circulation should be changed
and the process repeated.
Upon finished cleaning the boiler should be washed in
the same way with clear water.
For cleaning the
product, it is not permitted to use
aggressive media as e.g. gasoline, kerosene or solvent. For
the external shell and decorative cover media
for cleaning
plastics or dish washing media may be used. Control panel
should be cleaned with dry or moist cloth (not wet).
