Let me know if you found all the info you're looking for.

Found some manual.
You want to had a email address in your profile.
I'll be able toforward what I have to you

I have always used Pete's plug for pressure reading with a gage and needle.
Can you use it as a temperature well?

Any luck with the job?
Did r22 fix the issue?

Please let us know if it fix the problem

"Temperature is gonna be constant refrigerant is 100% vapor."
Was gonna say
Temperature is gonna be constant until refrigerant is 100% vapor.(or until the change of phase is completed)

The glide and instability on my side as prevented me to do the conversion.

As for the thermistor I understand what you are saying and there might be 30 F differences from one thermistor to the...

Exactly what ehsx said

I believe I saw the 30gt r134 as a option in the 30gt.
You are right it is a possibility in the 30gt.
Software is the limitation

Superheat not ajustable.
Only option is 29 F for r22 and another number for r134.
If you try to adjust it it revert back to setpoint for refrigerant.
At least on mine it's not working.
It's...

A conversion is a temporary fix.
On a rooftop might give the customer time to prepare a budget for equipment replacement.
On a chiller it's a big no on my side.

30gt use a sensor at the outlet of the motor at the back of the compressors for superheat measurement. It's not superheat nor discharge superheat.

The chiller was converted from r22 to whatever other refrigerant?

Got a customer who as the same exact unit. Personally I am against converting a chiller that as EEV and a "ref chart" programmed...

Not sure if it's good on J1000,but on z1000 and a1000
you just swap the terminal board .Parameter are saved there

If you have a plated heat exchanger some manufacturers will ask for a fine filter at the chiller inlet pipe. Not having it install will void your warranty.

Most of the time the pump filter is to...

With a simple google search I stumbled upon.
Max flow recommended at 2.5 inch is 75 gpm.
4 inch is the way to go.

At the evap what is the smardt pipe size, not the one from the building.

Got that for you.

Got one I'll flip it to you later today.

If you lost your liquid seal in the evap, you're passing ton of hot gas in the evap.
Creating a false load. Chiller is ramping up to compensate. That is why you see 85 at suction elbow

Jayguy is...

[emoji106]
No liquid seal in condenser, hot gas flashing in the line.
Probably increasing the load on the evap.
So 4 F between leaving and entering evap water temp

I believe that by having the hot surface in the presence of the flame it will lower its resistance and at a certain threshold it will prove the flame

You have bypassed the leaving water sensor?
Is the chiller controlled via the return?
Because you can badly damage your chiller by running it with leaving water feedback.

Next time if you can...

External demand limit.

Load limit for kw

Just saying your evap temp are well above your condensor temp you might want to check that out.
What type of compressor you got, screw or scroll?

Is your condensor installed below the evaporator or above?

If below you might want to take a good look at the piping.

If you want to check for bypass at compressor, and you have a mechanical...

Flow switch are installed to profile flow protection.
So what is your flow compare to design?
To pressure drop across in/out of exchanger.
Compare to safety setting of the differential switch

I've been using CDI torque wrench.
It's a sub company of snap on.
Nothing to complain about.
Price is fair and quality is good
http://www.cditorque.com/

Most of them.
There's is no calibration on a chiller brand I can think of

If it's a small package or you have a oil separator running unloaded with enough velocity should be good to get the oil back

We use a subcontractor that come with a truck that as a tank filled with water.
There pressure washer heat and push water to 3000 psi.
It beat everything else to my opinion.
Never seen coil so...

Make sure your testo are reading good.
For 10-15 psi on r410 it won't make a big difference.
Like Jay said you can change them if it's creating issues

I would suggest to look at fan contactors and fan motor.
If I remember right there is a contactor before the vfd.

Trigger board, logic board and IGBT is for the compressor only

I don't know if it come pre-programmed.
Probably you can ask Lennox supports for the parameters set.

If you can buy yourself one of those keypad from Mitsubishi and keep it in the truck.

When you get the 85 psi diff, which value is changing?
High pressure or oil pressure?

They are probably all the same capacity
So you need to divide the total capacity 100%by the compressors number 6
So basically 16.7% each step

It's not energy consumption its for staging and PID...

Not exactly your compressor but here is what I have written in my notes

Is there a message on the optiview panel?
If you reset it ,does it try to start

I don't remember. But I'm pretty sure you could find the information in the VFD parameters

Look at ifm spec. They specify to place sensor where there is no rapir6change of temperature

You can try to clean contact on the connector side of the wires that goes from the power supply to optiview.
Or replace the cable.

I'd say it should fix most of the issues

What is the problem?
Any reading or data?

Around 110-120 F

Hi,

Did you try to replace the amplifier card.
After a couple of years it provide less voltage for your flame rod signal.

Check the ground on the burner and make sure it's good.

Would definitively look at sensor as already suggested.
You got any log sheet ?
As the filter on the evap side in the manifold been cleaned?
What is the flow?

I would not recommend for now...
