Can someone tell me where I can get a list of the propper pressures for low side and high side pf a 10 seer 2 ton ac system with a copeland CR28KF-PFV-130 compressor both running and off? as well as how much r22 it should have in it?
Thank you

The pressure when it is off is mostly dependent on the ambient temperature around the part of the system that contains majority of the liquid refrigerant, usually the condenser, and varies with the conditions.

The pressures when the system is running are dependent on a number of factors, including, but not limited to, outdoor temperature, return air temperature, airflow, metering device size/type, and how clean the evaperator and condenser coils are.

The amount of refrigerant the system holds is based on the condenser coil design and refrigerant line length, as well as a number of other factors.

In short, nobody can possibly give you anything even approaching a correct set of numbers to answer your question, sorry.

First you have to learn the secret handshake.

Nah, just kidding. Here is the list you need; http://assets.fluke.com/appnotes/electricalpower/1265816_.pdf

Now all you have to do is learn how to do superheat and subcool calculations and how to determine what the relationships between outdoor ambient temperature, indoor return air temperature, dewpoint etc. are to the system pressures.

Let us know how this works out for you.

if you really wont to money you will have to call a pro. and if you dont you will most likly damage your unit and you will need to call a pro anyway and the cost could sore into the $1000s
