Connecting Direction For Refrigerant Piping; Noise Level - Mitsubishi Electric CITY MULTI PUHY-YSMF-B Installationshandbuch

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.
