13.4 Safety measures
13.4.1 No safety measure
When the room area is sufficiently large, no safety measures are required. This also
includes a BS unit installed in the lowest underground floor.
The duct connection must be replaced with the duct closing plate accessory (see
"14.5.2 To install the duct closing plate" [
4
66]).
BS unit test run
Before BS unit operation, it is required to perform a test run that simulates a
refrigerant leak. See
"18.3 BS unit test run" [
4
101] for more details.
