18.3 SV unit test run
18.3.1 About the SV unit test run
The SV unit test run has to be performed on all SV units in the system, before the
test run of the outdoor unit. The SV 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 SV unit test run and confirm the result,
because the test run of the outdoor unit checks this confirmation for all SV units in
the system.
Depending on the safety measure and the configuration of the SV unit, it is
required to perform the SV unit test run on a specific SV unit of the system.
Note: Do not perform a SV unit test run on more than one SV unit at a time.
▪ No safety measure: all SV units with no safety measures.
