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
