Figure 4.3. Recommended principal hydraulic scheme
for connecting the hot
water electric boiler of series “ELTHERM” to a heating system and heat
accumulator tanks.
ATTENTION: The finalization of the system installation and performing the
commissioning tests should be filled in the appropriate documents of the boiler,
where the required data fields should be filled in (this is obligatory).
4.3.
Procedure for connecting the hot water electric boiler of series
“ELTHERM” of the electrical power circuit.
NOTE
:
the electric hot water boiler of series “ELTHERM ” should be connected
to the electrical power supply only after successful connection to the heating
system has been performed, no circulating water leakages has been found and the
heating system is totally free of air (make sure to open all the control valves and
other control modules in order to allow the air to get out of the heating system)
.
Check the condition of the circulating pump’s rotor by unscrewing its protective
cap and observing the movement of the rotor at power supply of the pump. Do not
operate the boiler if the pump’s rotor is blocked as this will result in boilers
overheating
