For UKDAX-xxEDT and UKDAX-xxEDM models, this is done with the blue filling tap
on the bottom of the device. The filling should be done by following the instructions
below.
▪
Make sure that the cold-water inlet valve of the device is open.
▪
Turn on the filling tap.
▪
Open the air vents and discharge the air accumulated in the radiators
and shut them when water starts to flow.
▪
When the air accumulated in the radiators is discharged, there may be a
decrease in the water pressure of the heating system. Make sure that the
water pressure of the heating system is between 1-1,5 bars, if there is a
decrease, fill it up by opening the filling tap.
For UKDAX-xxETT and UKDAX-xxETM models, this process is done using the filling
valve to be connected to the heating system. For this, a valve connection must be
made from the cold water system to the heating system. The filling valve should be
close to the device and in a position that sees the pressure gauge on the device.
After the filling valve, there must be a silt trap. The filling should be done by following
the instructions below.
▪
Turn on the heating system water filling valve.
▪
When the water pressure gauge reaches 1 - 1.5 bar, turn off the filling tap.
▪
Open the air vents on the upper side of the radiators and discharge the air
accumulated in the radiators and turn them off when water starts to flow.

5.2.1.2. Filling the Heating System for ETT and ETM Models
After the heating system is filled, it should be carefully checked for any water
leak.
If the filling tap is left on and the pressure of the heating system exceeds 3
bar, water discharge starts from the safety valve inside the device.
