After completion of the repair work, perform vacuuming of the outdoor unit using the following procedure.

1. Short CN30 on the interface P.C. board on the outdoor unit for which the repair work has been completed, to

open the PMV fully. (Confirm that Bit 1 of SW12 is OFF.)

Note) The PMV opening by using short CN30 returns the PMV to fully closed after 2 minutes.

To continue to fully open status, turn off the power supply of the outdoor unit within 2 minutes after
using short CN30.
