Yes. That is a proper installation. No reason why flushing would be an issue. Did air come out when he last flushed it? I would look to see if...
Can you post pics of your interior piping, like where the flush ports are located in relation to the unit. Non Pressurized systems are great but...
Your delta T suggests that your flow is good. I would confirm the pressure drop with another gauge before making any changes
Is that 6 delta in first or second stage?
What is your temperature differential?
its not the smallest pump they make
Do you know what size the loop piping is? type of antifreeze and % ? I would call the installer explaining your conversation with CM and kindly...
Do you Know if they flushed/purged the lines when they replaced the pump(s)?
If you are getting a Internal Flow Center Fault and you don't have an Internal Flow Center than it is not configured correctly. Unfortunately...
These digital units need to be configured through a service tool or a thermostat. It sounds like yours was incorrectly configured. What kind of...
Clamp meter should get the job done. Your compressor will draw more based on the LWT being 5 degrees colder. It has to pump the heat a greater...
I think your installer is showing a lot of integrity exchanging your 3 ton for a 4 ton, assuming there no charge for this. I would hang in there I...
If I had a 10*F delta with the compressor in second stage I would not be concerned a bit. But since you have a cool monitoring system you may want...
If your pressure delta and your loop temp delta remains the same, set it at the lowest speed
the unit monitors the REFRIGERANT temperature and shuts it off at 30*. Not the LOOP temp. I would not be surprised if it shuts down with loop...
