 and then make sure that the that unit is is completely isolated electrically and then go in there and just blast away clean out the inside of it clean all the dirt out of it maybe you do need to get a shop vac nozzle down in there and suck up a bunch of leaves or twigs or whatever's down there collect it in the bottom of the pan maybe do that first while it's dry it's a lot easier right and then go ahead and rinse it all out rinse out underneath it rinse out behind it where it's up against the house
