The distributor on the return water distributor side should be placed lower than
the heating inlet.
Connection should be made by installing a safety valve with 3.5kgf/
偌
or lower
opening the discharge piping to the cistern tank.
The maximum operation pressure is 3.5kgf/
偌
. Do not supply water at a higher
pressure or directly connect the water pipe having the pressure higher than.
Overflow of water during the heating to the cistern tank means short tank
capacity. Exchange it with a larger one.
Backflow of water during the running or stopping of the circulation pump to the
cistern tank is caused by too much air in the pipe. Remove air by opening valves
on the distributor one at a time, while running the circulation pump.
Evaporation at the cistern tank means failure in the system. Contact your
representative to receive the check.
Never install any valve between the boiler and the cistern tank.
We will not be liable for any defect or breakdown caused by the failure to
comply with the above precautions.
