Hydroblock
There is a pump, 3 bar safety valve, filling valve, water pressure sensor, plate exchanger, turbine, 3
way motorized valve and immersion/surface NTC on this hydroblocks.
The pump suction is from the left side of the pump and the exit is upside as shown in the figure below.
Filling Tap
Filling tap has a basic structure. To fill the system, open the valve by turning.
When the water pressure reaches between 1,0 - 1,5 bars, filling tap can be closed.
Disassemble of filling tap:
Firstly disassemble the flow manifold and turn the tap.
Assemble of filling tap:
Turn the tap until closing the filling tap.
Pump
Pump central heating (central heating system) provides circulation of water. Also, in monothermic
models, the pump allows the central heating water to be circulated in the boiler, thus domestic hot
water is heated by water passing through plate heat exchanger. The pump is located on the
hydroblock. It has 3 speed range that can be adjusted. The pump has expansion tank connection hole
and an automatic air purge.
