Forced Operation
• To operate the appliance by force in case that the remote control is lost, the forced operation selection switch
is on the main unit of the appliance to operate the appliance in the standard conditions.
• When the power is supplied while the slide switch is on the forced operation position, or when the slide switch
position is switched to the Auto Restarting (or test operation) position or switched from the remote control
position to the forced operation position while the power is on, the forced operation is carried out.
• When the slide switch position is switched from the forced operation position to the Auto Restarting position or
the remote control position, the forced operation is canceled and the appliance stops operating.
