Unical KON 1 C24 - Filling the System

24
When the system connections have been completed,
the circuit can be lled.
This operation must be performed carefully, respect-
ing the following phases:
- open the radiator vent valves and make sure the
automatic valve is working properly in the boiler.
- open the lling tap gradually Rc making sure that
the automatic air release valves installed on the
system work properly.
- close the radiator air release valves as soon as
water comes out.
- check pressure (right value 0.8 / 1 bar) indicated
on the pressure gauge 36 (or from the remote
control parameter PS *).
- close the lling tap Rc and bleed air once again
through the radiator air release valves.
- make sure that all the connections are watertight.
- after commissioning the boiler (see par. 3.10) and
bringing the system to the operating temperature,
stop the boiler and repeat the air bleed operations.
- let the system cool down and, if necessary, return
the water pressure to 0.8/1 bar.
(See par. 4.4).

Parameter PS.
Attention!
Do not mix the heating water with in-
correct concentrations of antifreeze
or anti-corrosion substances! This
could damage the gaskets and cause
noise during operation.
