5.2.1.1. Filling Of Boiler
After installment is completed, boiler is needed to fill. This process must be done by
implementing following instructions.
Open boiler inlet valve of installment.
Open any tap connected to device hot water outlet. (preferably nearest tap). Air
inside boiler will be discharged from tap.
Close the tap after air discharged from tap and continuous water flow start.
5.2.1.2. Filling Heating System
For UKDAX-xxETP this process is made with filling valve which is connected to
heating system. It is needed to make connection with valve from cold water system
to heating system. Filling valve must be positioned as close to device and sight
pressure gauge of device. After filling valve, there must be silt trap. Filling process
must be done by implementing following instructions.
Open heating system water filling valve.
When water pressure indicator reaches between 1-1,5 bar, close the filling
tap.
Discharge the accumulated air inside radiators by opening air relief cock
placed in side of radiators and close when water starts to flow.
When the accumalted air inside radiators discharge it can be decrease at
heating system water pressure. Make sure that heating system water
pressure is between 1 and 1,5 bar. If decreases, complete by opening
filling valve
After heating system is filled, must be studiously controlled if there is water leakage
or not.
If filling valve is forgot as open and heating system pressure exceeds 3 bar,
drainage starts from safety valve inside device.
