Foundation Work - Mitsubishi Electric City Multi PUHY-P-YKB-A1 series Installationshandbuch

8. Foundation work

Install the unit in accordance with the instructions to minimize the risk of damage from
earthquakes and strong winds.
- Improper installation will cause the unit to topple, resulting in serious injury.
The unit must be securely installed on a structure that can sustain its weight.
- Failure to do so will cause the unit to fall, resulting in serious injury.
・When performing the foundation work, make sure that the floor surface has sufficient strength and carefully route
pipes and wires in consideration of the water drainage that will be required when the unit is operated.
・If considering routing the pipes and wires across the bottom of the unit, make sure that the base is at least 100 mm
(3-15/16 in) high so that the through-holes will not be blocked.
・Provide a strong base of concrete or angle iron. If a stainless steel base is used, insulate the area between the
base and the outdoor unit by putting a rubber cushion or by applying an electrically insulated coating to prevent the
base from rusting.
・Install the unit on a level surface.
・With some types of installation, unit vibration and sound will be transmitted to the floors and walls. In such locations,
take measures to prevent vibration (such as using anti-vibration rubber pads).
