The smoothing capacit-
ors (330µF x 3pcs.) are
charged to about 380V.
Don't forget to discharge
them before attempting
access to electric parts.
DISCHARGING CAPACITORS
1.
Turn off the indoor unit's power switch or unplug the power cord, and wait for
a minute or so.
2.
Open the cover of the electric parts compartment. Discharge electricity from
smoothing capacitors (330µF x 3pcs.) by connecting the leads of a soldering
iron of 30-75W to the terminals provided for this purpose. Continue discharg-
ing for more than 15 seconds.
