19
Open the service valves, fill up the unit/heating installation so that the pressure is 1,0-1,5 bar
(depending on the static height of the system) and start the purge programme.
X
20
Perform a test operation of the product and heating installation, including hot water generation,
and purge the system once more if necessary.

content (the air ratio) of the product again.
X
24
Ensure that there is no gas, flue gas, hot water, condensate or solar fluid leaking from the
product. If required, intercept the leakage.

X
25
Check the solar fluid level and top it up, if necessary.
X
26
Check the fill level in the glycol container and the pressure in the glycol circuit.
If the pressure is below 1 bar, manually actuate the air trap and correct the glycol fill level.
