(5) When installing the unit on a roof or a
veranda, drain water sometimes turns to
ice in a cold morning. Therefore, avoid
draining in an area where people often use
because it is slippery.
(6) In case of the drain piping is necessary for
the outdoor unit, use the drain-kit
(DBS-26 or DBS-26L: Optional Parts).

(7) The whole of the base of the outdoor unit
should be installed on a foundation. When
using vibration-proof mat, it should also be
positioned the same way.
When installing the outdoor unit on a field-
supplied frame, use metal plates to adjust
the frame width for stable installation as
shown in Fig. 4.10.
When vibration measures
are necessary,
add vibration proof rubber.
