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.
