Test runs
C A U T I O N
• Be careful during the test runs, as some of the safety functions remain disabled: the units operate for two hours
without switching off via the thermostat. The three-minute compressor protection is not enabled during the
test.
• Secure the rubber bushes to the panel using adhesive when the outdoor unit ducts are not used.
• The compressor remains at a standstill during forced stoppage.
