●
Do not install an air
bleeder as this may cause
water to spray from the
drain pipe outlet.
(Fig. 3-28)
●
If it is necessary to
increase the height of the
drain pipe, the section
directly after the
connection port can be
raised a maximum of
25 cm. Do not raise it
any higher than 25 cm, as
this could result in water
leaks. (Fig. 3-29)
●
Do not install the pipe
with an upward gradient
from the connection port.
This will cause the drain
water to flow backward
and leak when the unit is
not operating. (Fig. 3-30)
●
Do not apply force to the
piping on the unit side
when connecting the
drain pipe. The pipe
should not be allowed to
hang unsupported from
its connection to the unit.
Fasten the pipe to a wall,
frame, or other support as
close to the unit as
possible. (Fig. 3-31)
●
Provide insulation for any
pipes that are installed
indoors.
