Warning:
The system water injection pressure should not exceed 1.2 bar.
Always remember to turn off the water injection valve immediately after filling
water. Otherwise it may cause the heating system safety relief valve to open.
Check if the power and voltage meet the requirements, if the power polarity is
correct, if the earth connection is correct and the resistance to ground is normal.
Any problems with the power supply will lead to improper working and even
damage of the boiler, and it may injury the operator.
Carefully wash the entire heating system to remove all residues that might be
left in the system before it is put into operation, to avoid system blockage or
damage to the boiler during the future operation.
Open the hot water tap, fill water to boiler D.H.W system fully, until the water
comes out from hot water outlet.
Acces s to the tap water and heating water adding connector, then open the
tap water adding connector and heating water adding connector valve in turn,
fill water to heating pipeline.
Unscrew the automatic exhaust valve bonnet of the pump for 2 turns;
also you can discharge the air by the exhaust valve on the radiator.
Open the clockwise injection valve to fill cold water into the system fully,
until the pressure reaches 1.0-1.2bar.
Discharge the air inside the system, and open the exhaust valve of each
radiator until there is water outflow;
Check if the system pressure is lower than 1.0bar;
If nece ssary, refill water to the system with pressure stabilized at 1.0-1.2 bar;
If there is bubble during the long-term operation, the gas will be discharged
through automatic exhaust valve on the upper part of the circulating pump body;
After filling the water, remember to close the tap water and heating water
connector valve.
