Deputy, just wondering, did your guy notice if the blower ramped up to 100 percent during that 20 minute window?

Possible frost protection error 11 at that time maybe due to fault at blower....

With that 20-25 minute run before cycling almost might be worth a check to see if there is a loose low volt wire at the board and at outdoor unit. Possibly vibrating and interrupting the cycle. Just...

Hey Hoss,

I tried sending you a PM, don't know if it was able to go through as your a regular guest.
Get a hold of me if you can, my email is in my profile.
Thanks

Just do what you normally do during the course of your regular workday. If you find yourself in a jam and you have a lifeline to another tech or supervisor in your company definitely use it.

Just like in trucking... everything is always the truck drivers fault :)

Your working hours in HVAC vary according to the season your in. When cooling season is on, we are hopping crazy busy and 50 + hours in a week is normal. when its time to head home I stop the clock...

I was just explaining in general about the process of getting the target sh to show numbers rather than dashes.
You can accomplish this by placing your clamps at the service valves.



As for...

Yeah I got the k couples

Milwaukee m12 everything here. I don't go anywhere without my m12 bag full of tools

I calibrate atmospheric with valves open to to the air and as for my clamps I calibrate in the ice in my cooler that I carry in the van

That seems a lot faster than my way

I use mine everyday for pulling down systems. Never an issue

Contact FP . They will send you replacement valves.

With you clamps on you lineset at service valves. Cycle to you wet bulb/dry bulb settings. Press and hold enter until the beep sounds and your numbers start flashing. Allow time for the temp reading...

I use a cheap little $17 digital probe thermometer.
Does the trick Just fine and its fast

I am thinking oil return as well.
Interesting. Thanks for sharing.

Hey everyone
Thanks for the replies. Its appreciated. A day after I posted this the calls started coming in and been swamped ever since then.

CrRussell, thanks for the offer there. Greensboro/...

Make sure its not in backwards on the ahu.

I stand corrected on the R-410

If you got questions, your in the right place for answers.

You at least have to take and pass the core exam before you can even think about attempting the other exams. Therefore I would focus on passing the core to begin with.

There's always a prospective helper looking for a job :grin2:

hvac216,
thanks for catching me with the above 0 psig statement, I stand corrected, I should have said equalized at atmospheric. :)
technical terminology always gets me, I am more of a layman's...

if you rose to 2400 microns after you shut the pump off, wouldn't that be refrigerant still in the system, perhaps a little moisture as well?

if your level rose to a positive pressure (above 0...

I don't care who ya are, that's funny right there :cheers:

I feel like your running just fine. only you know if its cooling well in the conditioned space.
read them links and see where you stand. after that if you feel good about it, then good deal....

yeah the bottom of that chart is talking about non txv. the upper talks about Sub cool txv

let me ad this as it talks about TXV SC with the superheat as well.
Hopefully its formatting will...

Hopefully links are allowed. this shows the procedures for charging SC, look at the chart for your indoor and outdoor Bulb temps and your outdoor ambients and you will see that your 23* F SH is...

But on that system and them conditions superheat can be that high.
I have no idea what the load is in the conditioned space. But the 23* SH is plausible if there is a big load.

I understand what...

That's a txv system. So its charged by sub cooling. Documentation I found based on your model #s calls for 8-12 SC. At normal design conditions Your 23* SH is OK and in spec.

If the system is...

Add slowly and don't slug the compressor. Basically throttle it. Small bits at a time. Let stabilize and recheck superheat before adding more.

Actually I forgot. You don't have service valve on...

8-12* superheat would be what you want to shoot for. higher the superheat, the more starved the evaporator is. you definitely have to factor in them long linesets

if you can get the superheat...

That SH reading is much better than the 23* earlier.

now if you can get it down between 8-12 * .

seems like low charge

what's refrigerant capacity on name plate? figure in for the 60 feet...
