They're all a pain in the *** to service !, your installation if done right will save you a lot of headaches down the road. In Florida, big problem is algae accumulation and drain clogs, drain hole is about the the diameter of a pencil ! Mitsubishi, it's real easy to drop the drain pan down, but I've had issues with their condenser main control boards, had to replace 3 of them on a 12 system condo install but they may have fixed the problem by now. A few things on your install. Make sure your drain hose fitting is tight and positively drained away into a 3/4" PVC pipe, but it can get bulky back there when you try to mount the head against the wall with the freon lines back there. Second, get rid of the flare fittings and braze the connections. When you mount the head, the flares and copper can flex and create a leak, you need to be almost exact and need a second person to help if you stick with the flared fittings. Do not mount the head too close to the ceiling. You will need to pop the latches on top with a screwdriver to take the shell off for service. Lastly, buy a float switch for the drain pan. Mitsubishi( not sure on the others) have an on-board 2-pin port to hook it up, it's available where Mitsubishi are sold. Buy Nu-clean drain cleaner and treat the pan frequently. I just open the filter cover and pour it over the coils. Also check the plastic blower wheel once every 6 months, they easily accumulate dirt and mildew which can lead to problems, I usually hit it with compressed air. Sorry this was so long, good luck .
