Turn off the Sharp CV-P10MX air conditioner, but keep the unit plugged in.
Prepare a rubber hose with an inner 5/8-inch diameter by sliding the hose clamp that came with the unit around one end and pushing the drain grommet, which resembles a tiny cup, into the end.
Locate the drainage nozzle on the back of the unit, just below the exhaust pipe of the left side. The drainage nozzle resembles a dial with a small tubular hole in the center.
Turn the drain dial to the open position, so that it's positioned vertically. Remove the small covering, or stopcock, from the nozzle.
Push the drain grommet on the end of the hose over the drainage nozzle and tighten the clamp around the hose securely. Place the other end of the hose into a bucket.
Press the unit's power button two times to start the flow of water into the bucket. When the water has drained, press the power button once to turn the unit off again.
Loosen the hose clamp and remove the grommet and hose from the drainage nozzle. Replace the stopcock and turn the dial so it's positioned horizontally to close.
Place a shallow container under the drainpipe nozzle, located on the lower right side of the back of the unit. Remove the stopcock and allow the remaining liquid to drain out. Once drained, replace the stopcock. This step isn't necessary if you plan to keep the air conditioner running, but should be done before moving or storing the unit.
