- Unscrew the vent valve's release cap
- Open the shut-off cocks in order to slowly ll the system
- Use the pressure gauge to check that the pressure is rising
and the water is exiting through the vent valves
- Close the shut-off cocks after the pressure reaches 1.5 bar
- Start the system pumps and the thermal module's pump as
shown in Paragraph "Commissioning and maintenance"
- During this stage, check that the air is correctly eliminated
- Restore the pressure if necessary
- Switch the pumps off and on again
- Repeat the last three steps until the pressure is stabilised
b
The system must be lled up slowly the rst time; once it is
lled and the air expelled it should never need to be topped
up again.
b
Systems should also be operated at maximum working tem-
perature the rst time they are started up, in order to facilitate
de-aeration. (Gas is not released from the water at low tem-
peratures).
b
An automatic spurge can be performed during the rst ignition.
The parameter that set the cycle is Par. 2139. See parameter
table for more information.
