Before affusion, turn on the automatic air vent
valve on the circulation pump and the air-vent
valve at the end of the heating system.
Fill softened water into the preset position for
affusion on the pipe of heating system.Observe
the pressure meter on the operation panel,stop
filling in water when the pressure reaches
between 0.1-.12Mpa(1—1.12 bar)
Turn on the boiler (do not turn on the gas
valve),then the pump start working.when the
pressure drops to 1 bar, turn off the boiler.
Keep on filling softened water in until the meter
hands points to 0.1-0.12(1-1.2 bar). Restart the
boiler(do not open the gas valve),the pump will
start running.when the pressure drops again,
Repeat the above steps until the pressure keeps
steadily at 0.1—0.12 Mpa(1—1.2 bar).
Turn off the air vent valve on the end of the
heating system.
Caution:As the air cannot be exhaused from the
boiler completely at first affusion.the remaining air
may go with steam into the water pressure detection
system,which may result in the lace-water-protection
system running-Refill the water until the pressure
reaches to 0.1 -0.12Mpa(1 -1.2 bar).Turn the "reset "
button,restart until the system operate steadily.
The boiler is equipped with a manual valve for
affusion and refilling water.Add water when the
water pressure is below 0.1Mpa(1 bar) during the
operation.
Switch off the power supply of the boiler.
Check to make sure there is no water leakage
from the heating system.
Turn the Affusion/refilling water valve in an
anticlockwise direction.
Observe the water pressure metre, till water
pressure reaches 0.1-0.12Mpa(1—1.2 bar),turn
the affusion/refilling in a clockwise direcition,and
close the valve.
Restart the boiler.
Check the heating system pressure regularly.The
boiler pressure metre hand should be pointed at
the 1-1.2 bar. If the pressure is less than 1 bar(cold
boiler),refilling the water by affusion valve on the
bottom of the boiler.
Caution
Turn off the refilling valve after the Refilling
finished,If the pressure of the heating system goes
up to 3 bar,the safety valve will be opened.Please
contact the technician.
