I hope this helps you and thanks for choosing FixYa.

On the data plate for the outdoor unit it will tell you what type and how much refrigerant you need. If the line set is longer than 25 feet you will likely need a bit more than what it says. A 40 degrees evaporator temperature is ideal, approximately 65 psi for r22

Mitsubishi Mr slim comes with no diplay on the indoor unit but there is small display on th eremote unit.for further help kindly send your air conditones complete model

make sure you have freon in your system. they act as a heat pump which does A/c as well s heat. without freon you want have cooling or heat.

the water would not go to the drain pan if you install it vertically.

water would just drop anywhere and would ruin a lot of things...

Visit Mr. Slims website at www.mrslim.com. There you will find a tab for Customer Service. Look in Library to find your model and technical manual. You may have to look at a few to find out what you have for an inside unit, probably it is a PUG.

I am not familiar with a P8 code nor do I understand where you are seeing this But, go to mrslim.com and look under Customer resources, Library and then input your model number. Select Technical & Services. Product Catagory is Mr. Slim Ductless, Sub Catagory is M-series Multi Split, Current models. Remember you have inside units and one outside unit. You will need to look at each model number to find information on both. Usually Mitsubishi's will have two lights that will blink in patterns to indicate what could be wrong. The P8 code is new for this Diamond Dealer!

This usually indicates damage to the circuit board of the control unit assembly. We repair these control units nationwide for only $32.50 postpaid. If you decide first to remove or replace the bulbs or check the sockets or wiring, please unplug the microwave first. Failure to do that is usually how the boards get damaged. If you or a friend decide to work on it, we have *critical* safety and disassembly info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can usually find helpful exploded view diagrams and order parts by entering your base model number (without the suffix) here: http://tinyurl.com/gv383 BUT - I don't recognize NN-2501 as a valid model number. Could you confirm that? Thanks!
