How do you operate the dimplex dac-9005 air conditioner?

make sure unit is off!

remove the drain plug at the rear centre of unit,let all water drain then plug it back up. above the drain plug the is a mini drawer type thing, pull it open and slowly pour 800 ml of cool water in there. close the drawer and switch the power on. may take a little while but will work very well. if the red light at top of unit ever comes on, switch off unit and repeat above procedure.

cheers.
