needed, fitting constriction or blockage can cause inability circulation of
heating. Connections that are made to device must be easy removable when it
is needed. Valve and silt trap must be used for water and radiator inlet pipe
.
After hydraulic connections are made, filling the heating system is necessary.
For models of UKDAX –xxEDT and UKDAX –xxEDM this process is made
with filling tap under the device. This process must be done byimplementing
following instructions.
Be sure cold water inlet tap is open.
Open filling tap until water pressure indicator comes between 1 and 1, 5
bar.
Close the filling tap when filling is completed.
When the air collected inside radiators is discharged, it can be reduce at
radiator water pressure. Be sure by checking radiator water pressure is
between 1 and 1, 5bar. If there is decrease, it must be completed by
opening filling tap.
It must be checked studiously if there is water leakage or not.
