What should be the normal gauge pressure for my compressor?
reading of 35 psi will be okay?

Answer these few questions:

Outside air temperature?
Low side suction pressure?
High side discharge pressure?
Air from max ac with windows rolled up cool enough?

I'll help you in anyway I can

outside temperature:35 celsius
Low side port: 40psi
high side :100
inside blowing hot air


took system apart to clean, evacuated first and found water in back accumulator, dont know how water got there.
Will evacuate again once system is together: 500 to 1000 microns for water to be removed.

when charging the system, will 3 cans will make it?
134a 12oz

 

A "normal" set of readings would be low side cyling from around 23-25 psi up to around 42-45 psi with high side readings from 150 psi and up. These pressures can vary a great deal depending on your temperature. Having the chart on hand that shows what to expect is a very good idea.

I am away from my server until Monday. I can look then for any documents you still need than.
