NOTICE
The equipment described in this manual may cause electronic noise generated from
radio-frequency energy. The equipment complies to specifications that are designed
to provide reasonable protection against such interference. However, there is no
guarantee that interference will not occur in a particular installation.
It is therefore recommended to install the equipment and electric wires in such a
way that they keep a proper distance from stereo equipment, personal computers,
etc.
In places with weak reception, keep distances of 3 m or more to avoid
electromagnetic disturbance of other equipment and use conduit tubes for power
and transmission lines.
▪ Take care that in the event of a water leak, water cannot cause any damage to
the installation space and surroundings.
▪ Choose a location where the operation noise or the hot/cold air discharged from
the unit will not disturb anyone.
▪ Air flow. Make sure nothing blocks the air flow.
▪ Drainage. Make sure condensation water can be evacuated properly.
▪ Paper pattern for installation (upper part of packing) (accessory). When
selecting the installation location, use the paper pattern. It contains the
dimensions of the unit and the required ceiling opening.
▪ Air flow directions. You can select different air flow directions. Choose the one
best suited for the room. For more information, see the installation manual of
the optional blocking pad kit.
