Guys good afternoon and sorry for the inconvenience ... I have to face this afternoon to measure a York prayers of 12,000kcal ... The client sent me images and I see that he has DOUBLE SERVICE VALVE ... Obviando that I will measure by Low and that it should be at about 55psi since the Current Temperature in Rosario round Today the 18/20 degrees ... The Alta valve that too. Do you have access to connect service hose, what parameter can you give me? WHAT MIGHT I NEED TO MEASURE HIGH PRESSURE? I do not know of industrialists and I want to see the possibility of giving a hand to a friend who inaugurated a place a few months ago and is not doing very well ... Thanks in advance! Lucas de Rosario, Sta Fe.

Hi Lucas ... whenever you have the possibility to measure the high, keep in mind that it is as important as measuring the low since both pressures will give you a clear picture of the operation of the equipment, in your case you place the double manifold (high and low) and medis both simultaneously, low 55/60 psi high 230/260 psi would be the normal parameters. Note that if you have a Rotalock type service valve you will connect the manifold and it will not give you any measurements, you have to open the valve 1/4 or 1/2 turn clockwise (that after connecting the manifold) and before you remove it you return to its original state. Good luck, regards.

Manu good night and thanks x the contribution ... Visit my friend and I found a Carrier of 15000Kcal Cold only about 9 years old ...
When energizing the equipment, the "chicharra" of the plate began to sound constant and I found that, besides having been intervened several times, they installed a Generic Display, which when energizing makes a flash of the lights but soon falls off...
The team could never turn it on, which brought me the money because in addition several are desolate and when removing the terminals came with ...
WHY THE CHICHARRA RINGS?

Surely the problem is on the board or some bad connection. If, as you say, they already put their hands on you ... you will know what they did. I would choose to rearrange everything, test compressor, fans and sensors each separately, see the features of the equipment and put a chord board. Greetings.

As I did, I came across spliced ​​cables, tapes and so on. I brought the plate with control and Display Generico of those that have the shape of "crescent", I took it to the electromechanical and Friday I'm going to go start the compressor and control the turbines and other ... I want to give a hand to my friend but I do not want to screw up ... Thanks x your time Manu ..
Weekend I tell you what happened ...
