ÜNMAK – Radiator User Manual
FIRST START-UP
In order to fill the heating system with water, it must be connected with a hose from the lowest code entry of the
system. The vent must be left open for air to exit from the highest point of the system. This is not necessary in open
expansion systems. The environment should be filled with water by opening the faucet, then it should be connected
to the point where the water will be pumped. If the lowest code is in the radiator, while the system is flooding, if
there is a manometer in the heating device, it should be observed with a manometer and the system should be
brought to around 1-1.5 bar.
Care should be taken not to leave any air in the system.
MAINTENANCE AND CLEANING
Regular checks:
• It should be checked whether there is a water leak (leakage), and if there is a water leak, the installer should be
contacted.
• Radiators should only be cleaned with a lint-free cloth with warm water and no chemicals.
Periodic checks:
• By separating the sides of the panel radiators, the grids on them can be removed and the gaps between the
convectors can be cleaned, or by blowing air from above with a hair dryer without removing the grille, the dust
can be poured from below.
• While the system is running, the radiator surfaces should be checked manually from bottom to top to see if there
is a cold zone. Being a cold zone indicates that there is air remaining in the radiator.Sezonluk kontroller:

RADIATOR BLEEDING
It is taken from the places shown in the figure, the air vents. A deep container should be found and precautions
should be taken for the dirty water to come out. The system
should be started and the pressure should be increased up
to 2 bar. With the air vent wrench or flat screwdriver, the
screw on the air vent should be turned counter clockwise
slowly. If air is trapped in the system, it will come out at this
time. When the water starts to flow properly, its air will be
taken. Then the pressure of the system should be checked
and brought to around 1-1.5 bar.
