18.3 BS unit test run
18.3.1 About the BS unit test run
The BS unit test run has to be performed on all BS units in the system, before the
test run of the outdoor unit. The BS unit test run has to confirm that the required
safety measures are properly installed. Even when no safety measures are
required, it is necessary to perform this BS unit test run and confirm the result,
because the test run of the outdoor unit checks this confirmation for all BS units in
the system.
Depending on the safety measure and the configuration of the BS unit, it is
required to perform the BS unit test run on a specific BS unit of the system.
Respect the sequence indicated below.
Note:
Do not perform a BS unit test run on more than 1 BS unit at a time.

all BS units with no safety measures.
