It's close coupled like probably less than 3'

Go figure.

Is there water in the vaporizer pan when he's measuring the LL temp before the valve?

Also when measuring evaporator SH the top panel needs to be in place so air is being forced through the coil.

Measuring with the top off could give an inaccurate reading.

Looks like a simple unit.

If it worked before it should work now.

What about a pump down test to see if the valves are leaking by?

With no liquid valve how about a compressor performance check?

Package units dont have service valves .... so thats out

How's the insulation on the suction line?

Is there a suction accumulator before the compressor??

Insulation is all good. And no accumulator before compressor

Are you sure the condenser is clean? Did you wash it or just blow it out?

Yes it is very clean I can put my anemometer in from to measure the airflow

I thought that. What are linesman pliers used for anyhow? Package unit pumpdown tests?

Interesting. What were the results?

Try closing the x valve a half turn. Now what is all your temps and psi's?

There are suction and discharge access valves

Would need the compressor BOM ( Bill Of Materials )

6 X 10 🤔

No water in pan. And top is on. I’m thinking I evacuate the unit and do a pump down

Too small of box?

The opposite
6 x 10 needs at the least 5,000 BTU closer to 6

[Red850kid]

Somethings fishy about this thread...

[Red850kid]

Yes try evacuating and changing the fd/ adding a MISG.

Weigh in fresh gas. Did you try adjusting the valve at all?

Ya know, just to try to get a lower SST?

How about seeing if the bulb reacts to temperature change(if there is a remote bulb).

Or to simply see if the valve modulates when adjusted?

[VTP99]

Not gonna happen with that condensing unit sorry

If you knew the reading, then that would help but we Don't know so look thru it. You should see clearly through the coil. If you can't wash it out.

Go to the Emerson site and download the performance curve for that pump.

Or download the Mobil App and run the #'s
