1. Remove the caps
from the valves.
2. Begin the commissioning
process by briefly opening
the shut-off valves of the
outdoor component until the
manometer displays a pressure
of approx. 2 bar.
3. Use leak detection spray or
suitable devices to check that all
the connections are leak tight.
If no leaks are found, fully open
the shut-off valves by turning
