In cold areas, do not use a drain hose with the outdoor unit.
Otherwise, drain water may freeze, impairing the heating
performance.

See figure below for installation of the drain plug.
2
Connect a field supplied vinyl hose (internal diameter of 25 mm)
to the drain socket (A).
If the hose is too long and hangs down, fix it carefully to prevent
kinks.
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 keeping proper distances away from stereo
equipment, personal computers, etc...
In extreme circumstances you should keep distances of
3
m or more and use conduit tubes for power and
transmission lines.
