                  After placement upon roof jack assembly, installation was pretty straightforward. Had to manhandle it a bit. Leveled, corner legs installed, silicone applied, system wired. Looks good on the roof.

                    I WOULDNT BUY ANOTHER ONE OF THESE...
                    Save your money and do not buy this.... after purchasing this last week and installing it this past weekend, i am not satisfied one bit at all. I replaced my old style, rusted out in every corner, down draft 3000DD unit with this model ADA51. The 3000DD was already there on my roof when i purchased my home three years ago. Big difference between these two units, don't be fooled by the looks of the ADA51 unit. My old style one, the 3000DD which uses the Aspen pads, kept my house so much cooler on low speed. This model does not compare at all to keeping my house cool... not one bit at all, on either speed. Only at night is it some-what noticeable. My 3000DD made my house at night like a freezer, and very cool in the day, much more cooler than the ADA51 unit, again, this unit DOES NOT compare to the 3000DD. I thought we had put the Media in wrong as we did take it out for installation, but we did put it back in correctly after all. I did some research and talked with owners of this unit in my neighborhood before purchasing it, they all approved of it. That's why i purchased it. Sorry, i don't approve of it. In short, my 3000DD was much better and a lot cooler. I'll never buy this style again. In fact, i am thinking about returning it to the store. Complete waste of money, a lot of hard earned money. Save yours. Now the positives with this unit: Has a replaceable plastic tray that the water sits in so the bottom of the unit will have a much more prolonged cabinet/floor life (wont rust out). If only the 3000DD had that (they should come with it, Essick). Installed semi easy with a friend of mine with a minimum amount of tools and some foil tape. A neighbor thought it was an a/c unit, lol. Looks great (works lousy tho). Strong sturdy cabinet that comes apart easy to install motor/access the media etc etc. Comes with the water circulation pump and scale screen installed already, Power cord, Bleed Off kit (but i used the optional Powerclean purge pump instead, sold seperately as shown in orange), Media (has 5 year warranty), Power plug-in base (which can be put on either side of the cooler), Belt, Drain outlet. But again, not a good working unit... sorry Essick/HD

                    Great Unit
                    I have had this style cooler since 1983 and this is my 3rd one. I find with correct size down pipe and 3/4 HP motor with pulley set correctly it works absolutely awesome. And of season maint is a breeze. If your cooler is not cooling a 1600sq ft home either the down pipe is sized wrong or your pulley adjustments on your motor is not set right On my original unit the pulley wasnt adj right and wash disappointed until installers came out and did a readjust worked great after that so we need to remember its not completely plug and play. Check this items and let us know.
