• Make sure that the length of the foundation bolt is within 30 mm, 1-3/16 inch of
the bottom surface of the base.
• Secure the base of the unit firmly with four-M10 foundation bolts in sturdy locations.
Installing the outdoor unit
• Do not block the vent. If the vent is blocked, operation will be hindered and break-
down may result.
• In addition to the unit base, use the installation holes on the back of the unit to at-
tach wires, etc., if necessary to install the unit. Use self-tapping screws (ø5 × 15
mm, ø13/16 × 19/32 inch or less) and install on site.
Warning:
• The unit must be securely installed on a structure that can sustain its
weight. If the unit is mounted on an unstable structure, it may fall down and
cause damage or injuries.
• The unit must be installed according to the instructions in order to minimize
the risk of damage from earthquakes, typhoons, or strong winds. An incor-
rectly installed unit may fall down and cause damage or injuries.
