(5) The drain water is discharged during the
heating and defrosting operation. Choose
a place where well drainage is available, or
provide a drain ditch.
(6) When installing the unit on a roof or a
veranda, the drain water sometimes turns
to ice in a cold morning. Therefore, avoid
draining in an area where people often use
because it is slippery. If installing such
the area, provide a second drain pan and
perform the drainage.
(7) Use the drain boss set (Optional, DBS-26(L))
when the drain piping work is required to the
outdoor unit. Pay attention that the drain
boss set can not be used in a snow and a
cold area.
