Hi, got this portable AC/Heat Pump from someone who burnt me on it(I should have known better)... Anyways it is flashing HL as soon as its been plugged up. I have taken the casing off of the unit to have a better look, there is absolutely no water anywhere because it has been in storage and unused since last year(according to the person).
So, I have verified there is not water, I have checked the float switch and it seems like it should be working it has a nice little click when raised. I have followed the wiring back to the circuit board, I do not see anything on the board that is alarming(blown caps, burnt marks or anything) I have connected the 2 float switch wires together to see if I could bypass the switch but it did nothing for it... I have verified 120v coming in from electrical.
There is a little black box on the circuit board that gets power from a brown wire and looks to me like its supposed to put power out to the top of the compressor via the red wire that comes out of the little black box also. It gets 120v on the brown wire but the red wire has nothing.
I know its probably a lost cause but I am trying to figure this out since I wasted the money on it... Any help would be appreciated. Thanks Little black box in the top right of board has power in on brown but no power out on the red

Reason: adding pictures
Your pictures are too small to be helpful.
The manual doesn't even list HL as a fault code. It does list Hi.
That "black box" in the corner is the compressor relay.
The board tells that relay to turn on to run compressor.
That wiring diagram is illustrating an inside and outside unit yet the manual disagrees.
Indoor and outdoor fan motors.
I've never worked with a portable heat pump unit before.
On the surface it appears to be marketing hype.
Do you have two independent units that form a system ?
It may be indicating two motors in the same unit.
There is no technical info on your unit which is normal for Delonghi.
My daughter just bought a house. 1300 sq feet located in the PNW (which means it doesn't get that cold and normally doesn't get too hot but we do get slammed with wild fire smoke/soot every year). 3 bedrooms, 2 baths. A family room/kitchen open area (courtesy of non-load bearing wall being removed) makes up half of that 1300 square feet and that portion of the house had a vaulted ceiling). One level ranch with very accessible/roomy crawl and I would give the attic a 5 of 10. Half of it is very workable and then you hit the side of the house that is vaulted with scissor trusses. Built in 1990 and just a track house and certainly not a model of energy efficiency (I've have already started with some air gapping and will do what I can to button it up). Right now, there is no traditional HVAC, just Cadet wall heaters (no gas to the property, just electric). Originally 5 Cadets total but I took a circuit out of the removed wall so now down to 3 in the bedrooms on a different circuit (remaining have been checked to validate not on the recall list). She wants to take out the rest of the Cadets and put in heat/air. I assumed going into this that the most obvious solution with no ducting was going to be multizone minisplits and then we would have to figure out ventilation (presumably combo of some higher end exhaust fans and some air intake with filtration to balance out). I was holding off on specing out the ventilation thinking that given the house set up that it may be easier to install a "traditional" HVAC system which would have ventilation. First HVAC outfit came through yesterday and they proposed a sort of traditional system. It was a 30K BTU Mitsubishi single zone condenser and a matching air handler (SUZKA30NAHZ and SVZKP30NA). Condenser outside, handler in crawl and ducting from there out to 9 vents for supply and one return vent. Do not have Manual J calc and the outfit yesterday roughly sized the equipment based on number of vents. I'm sure this is TMI. I'm not going to DIY this. Above my pay grade and I want it permitted. My goal here is mainly to be an educated consumer as we have a few other outfits come through since the first quote was a lot of money for her. I personally like the solution because it addresses ventilation and she likes it because it doesn't have air handlers on the walls but the $$$.... Questions: 1) I have been unable to find anything online showing a configuration as being quoted and what I've seen are the "classic" air handlers that hang on the wall for a mini split and how would the ventilation be handled on this air handler (not obvious to me from the picture or reading the specs); 2) If she ended up going with a regular multi-zone mini split system am I over thinking the need for ventilation?; 3) should we get a Manual J calc (I've done it on my house but it's her money...); 4) other questions I'm not thinking of in my quest to become an educated consumer? I realize that the first proposal is very close to a traditional HVAC set up sans a furnace/air handler being able to generate heat if it gets super cold (this unit is rated to handle temps we would likely never see in the PNW). Apologize for the rambling and all help appreciated. Read More
