The
DPLS1
Drain
Pan
Level
Sensor
/
Control
provides
protection
against
drain
pan
overflow
in
Mitsubishi
Electric
Mr.
Slim
and
CITY
MULTI
Indoor
Units.
The
unit
will
sense
a
high
condensate
level
in
the
drain
pan.
Should
this
occur
the
control
shuts
down
the
indoor
unit
before
an
overflow
can
occur.
A
thermistor
error
code
will
be
produced
should
the
DPLS1
activate
indicating
a
fault
which
must
be
resolved
before
the
unit
will
re-start.
This
unit
provides
electronic
overflow
protection
for
Drain

in
all
Mr.
