D A N G E R
• Before installing the electrical wiring or before performing a periodical check, turn OFF the main switch to
the indoor unit and the outdoor unit. For safety reasons, be sure that the indoor fan and the outdoor fan have
stopped.
• Prevent the wires from touching the refrigerant pipes, the plate or cutting edges and the electrical components
inside the unit, to prevent them getting damaged. In worst cases, a re may occur.
• Tightly secure the wires with the cord clamp inside the indoor unit.
N O T E
• In case of performing a test run operation take especially care because some security features are disabled:
the units will operate during 2 hours without Thermo-OFF, and the 3-minute guard for compressor protection
will not be effective during the test.
• Fix rubber bushes with an adhesive on the panel when the conduit pipes to the outdoor unit are not used.
• In forced stopped compressor mode, the compressor operation is OFF.
