Mitsubishi Electronics PUHY-YMC Connecting direction for refrigerant piping, Noise level

Down piping and down wiring precautions

When down piping and down wiring are performed, be sure that founda- tion and base work does not block the base through holes. When down piping is performed, make the foundation at least 150 mm high so that the piping can pass under the bottom of the unit.
