fixing can be possible.
When the vibration measures
are necessary, add vibration
proof rubber. (Field-supplied)
When installing the unit, the location with good drainage should
be selected, or establish the drainage.
It is recommended not to install the unit at high place such as on
a roof or a veranda, because the water may drip from the unit.
If the unit installation at high place is not avoidable, the drain
water should be treated surely by installing additional drain pan.
(Especially in winter, the drain water may be frozen and cause
of injury by slipping.)
4 In case of the drain piping is necessary for the outdoor unit,
use the drain-kit (DBS-26 : Optional Part).
