How
to
Attach
Drain
Pan
The
air
conditioner
employs
a
proper
drain
method
whereby
the
condensed
water
(moisture
removed
from
the
air)
is
drained
to
the
outside.
In
very
humid
weather,
(and
for
reverse
cycle
models
in
the
reverse
mode)
excessive
condensate
water
removed
from
the
air
may
cause
some
water
to
collect.
To
remove
this
excess
water
you
can
install
the
drain
pan
as
detailed
below.
1.
Take
the
drain
pan
which
is
located
in
the
air
discharge.
2.
Remove
the

rubber
from
the
base-pan
(for
some
models).
3.
Install
the
drain
pan

filter
should
be
checked
at
least
twice
a
month
to
see
if
cleaning
is
necessary.
Trapped
particles
in
the
filter
will
build
up
and
block
the
airflow.
This
reduces
the
cooling
capacity
and
also
causes
an
accumulation
of
frost
on
the
cooling
coils.
1.
Open
the
inlet
grille
upward
by
pulling
out
the
bottom
of
the
inlet
grille.(a)
In

case,
you
can
open
the
inlet
grille
downward
by
pulling
out
the
top
of
the
inlet
grille.(b)
2.
Remove
the
