Hey thanks for watching this video is from service technician, Erik Mele. He does a lot of commercial work as well as commercial refrigeration and in this job he finds a particular problem. But what this video is actually about is preventing refrigerant flood back after you get the compressor up and working Erik's a very thoughtful technician, and whenever you're running a compressor, you need to think about. Are you potentially bringing liquid down that suction line, where it's going to get into that compressor and cause either a flooded start or flooded running, because it will cause damage, even if it doesn't make it into the head? It can cause damage by washing that oil out of the compressor, which then results in loss of lubrication hope you enjoy here on this freezer, I'm a little out of practice.

I ran to the indoor unit and saw on e7 error code, which I thought was compressor shutdown, so I come up to the roof. Well, let me back up a bit, so I went in the monitor menu. It's a beacon - and I looked at what I thought was suction pressure and it was showing two. So I came up to the roof and checking its 60 up here.

60. Psi equalized, so I'm like well, that's not correct. Maybe I have a bad pressure. Transducer downstairs.

So I go back down and I verify e7 is the compressor shutdown error code and the setting I was looking at was valve position and not suction pressure. So long story short, I got no power to the disconnect. I check to see if I have anything grounded in the unit before I restore power, so I'm gon na go down now and restore power to the disconnect we're gon na see what happens. They've been having tons of brownouts at this store.

I know it took out an automatic door the other day and had a couple other issues. So maybe it's a reset and run call. Maybe not here we go. We got a tripped breaker 20-amp on the show, but I think that's good for the unit's.

Alright. Now one thing to keep in mind: I got a interesting situation right. I got my freezers at 10:00. This this condenser also does the same box.

I got 60 psi equalized in the system. I am low side because this thing's been trying to run without a compressor. I don't wan na flood out this unit and since it's a beacon, it's kind of gon na do what it wants with the EEV. I got no good control over that.

So I have the receiver closed. I have the suction closed. I'm gon na pump this thing down and I'm gon na crack the suction and use that to hold back the refrigerant. So I slowly bring it back to the compressor and store it in my receiver.

Before letting this thing run, I don't want to just rip it open and all that liquid, potentially that's in the coil, unless it's low for some reason, but potentially my whole system charge is in my evaporator right now, because it's hot out here, it's cold in there. I don't want to flood this out, no accumulator, so I'm not gon na be able to get it on video because I got too much going on, but I have to engage that contactor throttle this and watch my probes on my phone. So that's the idea of what I'm gon na do I'm gon na very slowly. Let the refrigerant come back and stack up in the receiver, everything that's in the suction side of the system right now, then I'll.

Let it rip and see what happened so after easing it back on, we got a foil plate glass. We got a clear sight: glass, everything's good. It was just down so low in pressure because of how cold it is down there, which is what I expected. I didn't expect it was gon na be low, but you never know until it gets running.

That's gon na be it for this call. Actually, let's check that breaker sighs forget max overcurrent 20. That's right what it's supposed to be so we'll let it run and uh. I think it was just a brownout and I got another call over there.

I already looked at that's that first stream, but that second is rusted through the condenser: nothing exciting there. That's what happens when the ocean is right on the other side of those buildings that one's of 2013, this one's getting already getting replaced. I already wrote this one up, I'm getting a new curve on this one new disconnect, I think so, 2015 or 16 is done. It's already got a coil done, that's what happens.

I mean we've replaced both of these units, all three of these units, somehow that sandwich case is hanging on, but I know I'll be back for that soon anyway, thanks for watching.
