GENERAL INSTALLATION GUIDELINES
• I-Beams can be used as a base support.
• Operation sound and vibration from the outdoor units
may transfer to surrounding floors or walls; to reduce
vibration and operation sound, add anti-vibration
materials to the concrete base.
• Ensure there is enough room under the outdoor unit
if installing the piping and wiring using the bottom
access holes.
• The corners of the outdoor unit must be attached firmly to the
support, otherwise, the bolts may bend, cause the outdoor unit
to fall, which may result in physical injury or death.
• Attach the bolts tightly as shown to ensure the outdoor unit
will not fall due to earthquakes or strong wind gusts, causing
physical injury or death.
