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
attach wires, etc., if necessary to install the unit. Use self-tapping screws (ø5 × 15
mm 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.
Caution:
• Install be unit on a rigid structure to prevent excessive operation sound or
vibration.
