Test runs
! CAUTION
• 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.
4.1.5 Electrical connection of RCIM units
Before proceeding to any electrical connection
1 Turn off the power supply switches before starting work and t the appropriate locks and safety warnings.
2 Wait 5 minutes after turning off the power supply switches.
3 Check that the fans on the indoor and outdoor units are at a standstill before starting work.
? NOTE
• The electrical power for the unit must involve a specic power line, with an exclusive power control switch and residual current breaker,
installed in line with local or national safety regulations.
• Check that the electrical power line has enough capacity to supply the unit. Its length, the cable diameter and their protection (sleeve
or jacket) must be appropriate for the unit.
• For further information, always consider the current regulations in the country where the unit is to be installed.
! CAUTION
• Risk of re: cables must never touch the refrigerant pipes, printed circuit boards (PCB), sharp edges or electrical components inside
the unit to avoid damaging them.
• Loose connection terminals may lead to cable and terminal overheating. The unit may operate incorrectly, leading to a risk of re.
Check that the cables are rmly secured to the connection terminals.
