If you're getting water inside, you need to put more tilt into the unit. The back end should be tilted down, no less than 1/2" per foot. If the AC is 1 1/2 feet long, from front to back, the back should be AT LEAST 3/4" lower than the front. MORE IS BETTER.

12,000 but/ton. If the 101 in your model is their tonnage (101รท12=8.4. its a 8 1/2 ton (5 ton and a 3 1/2 ton combined). That's probably it or very close. I could not look it up cause I don't know the maker of the unit.

The blinking is an indicator that it needs service. Call a technician! Ask if they are experienced in mini split systems. You can check the air filters. Check the outdoor coil to see if its clean or covered up with dirt. And at the breaker or disconnect, turn off power, wait 5 mins, and turn it back on. Then give it 3-5 mins to see if it will reset itself. If this don't work, call a tech/service provider! These units are troublesome to troubleshoot.

Check to see if you have fan on automatic or continuous run ,it should have a setting so you can get air flow at all times or just when unit runs

You have to try resetting the system. First turn the breaker off for the condenser and wait about 20 seconds. After you turn it back on the system should reset.

Supposedly if you have the old filter you can wash it with baking soda. I can't locate the parts. You might have to contact a factory authorized dealer to purchase the filter if it requires replacement.

your main board more so the pipe sensor connected to it, is defective. if the pipe senor can be changed it will work but in most cases the whole main-board will have to be changed as well.

The remote batteries could be defective or installed incorrectly. Try removing the batteries, pressing all buttons to eliminate the possibility of a stuck one, reinstalling batteries and testing operation. If no operation, the remote may have failed or there could be failure at the wall unit.

Cooler than normal discharge air temperatures are kind of nature of the beast for an inverter compressor system. An inverter compressor has essentially an infinitely variable output due the varying speed of the compressor. When is is running slower the transfer of heat is less than when it is running full bore. At least on a mild day. On a cold day, even running at full speed, the leaving air temperature can feel a bit cooler due to the lack or heat available in the outside air to transfer in to the indoor coil. The Mitsubishi's are capable of running down to 5 degrees above zero without the addition of a low ambient control kit and the nearer it is to that temperature, the lower the leaving air temp will be.

There's only about three more 300 page VOLUMNs of information available to describe the function of these little guys, but maybe just a taste of the info will satisfy your concern. Of course what's written above is a very Cliff Notes version with a lot of holes in the description.....but you get the drift.
