the board until a click
sound is generated, then
connect the lead wires
shown right.
2 Next connect the lead
wires in the route shown
below and fix them with
tie wrap in the following
order.
Connect the fan
motor lead wire to the
connector X20A.
Connect the lead wire
of capacitor for fan
motor to the
capacitor.
Insert the lead wire of
drain pump to the
connector X25A.
Connect the lead wire
of float switch to
X15A through the
specified path and
wire clamp 1.
Insert two thermistors
to the connector
matching the color
with X17A and X18A
through the wire
clamp 1
(e.g. connect the wire
with yellow tape to the
yellow connector).
Connect the lead wire of
float switch and two
pieces of wire of
thermistor to the switch
box by using tie wrap .
(Use tie wrap properly to
prevent the wire from
contact with hot part of
the PC board.)
Insert the rubber bushing
of air temperature
thermistor into the slit
