Installation
(continued)
Do not install the unit where combustible gas accumulates around the unit, it may cause fire or explosion. The
outdoor unit produces condensation during the heating operation. Make sure to provide drainage around the
outdoor unit if such condensation is likely to cause problems such as freezing over in cold weather. When installing
the unit within the grounds of a hospital or a building where communication equipment is installed, you may need to
take measures to reduce noise and electronic interference.
When installing the outdoor unit on a rooftop or other location where the unit is exposed to strong wind, do not face
the air outlet of the unit directly into the winds. Strong wind entering the air outlet may impede the normal airflow
and it may result in a malfunction.
The following shows three examples of precautions against strong winds. Face the air outlet towards the nearest
available wall keeping about 50cm distance (fig 3.8) Install an operational air guide if the unit is installed in a location
where strong winds such as a typhoon, etc, may directly blow to the air outlet. Position the unit so that the outlet air
can blow at a right angle to the seasonal wind direction, if possible.
NECESSARY SPACE TO INSTALL
When installing a single outdoor unit. When installing multiple outdoor unit
Installation Procedure:
Be sure to install the unit on a solid, level surface to prevent rattling noises during operation. Make sure that the
length of the foundation bolt is within 30mm from the surface of the base.Secure the base of the unit firmly with 4
M10 foundation bolts in solid locations.
INSTALLING THE OUTDOOR UNIT
Do not block the vent. If the vent is blocked, operation will be hindered and the unit may breakdown. If additional
fixation of the unit is necessary, use the installation holes on the back of the unit to attach wires, etc, with self-tapping
screws (Ø5 x 15mm or less).
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 by earthquakes, typhoons, or strong winds. An improperly installed unit may
fall down and cause damage or injuries.
