WARNING
•After installing the product, be sure to perform leak tests on the piping connections. Before pumping down refrigerant to inspect or relocate the outdoor unit, be sure to stop the compressor and then remove the connected pipes.
––Do not operate the compressor while a valve is open due to refrigerant leakage from a pipe or an unconnected or incorrectly connected pipe. Failure to do so may cause air to flow into the compressor and too a high pressure to develop inside the refrigerant circuit, leading to an explosion or product malfunction.

4Turn off the air conditioner and switch mains supply off.
5Disconnect tubing. After disconnection, protect valves and tubing ends from dust.
CAUTION
•Compressor damage may occur if the compressor is run at a negative suction pressure.
