7. check with an electronic leak detector If a soldering failure is detected open the valve before soldering to equalize the pressure and keep solder from being blown out of the joint or sucked into the piping As soon as the repair is completed charge the correct amount of refrigerant into the system Remember that each system requires a specific amount of refrigerant with a tolerance of 5 grams See Figure 4 Fig 4 Before performing this operation if the vacuum pump and charging cylinder are still attached to the system be sure the valve between the pump and the cylinder is closed to keep refrigerant out of the system See Figure 5 For gas charging check the graduated scale on the cylinder to see the amount of refrigerant that it contains and the amount that will be pumped into the system For example if you have 750 grams of refrigerant in the cylinder and we have to pump 165 grams to the system this amount will be reached when the indicator reaches 585 grams remember that the indicator shows a lower level of meniscus Do this after choosing the scale corresponding to the gas pressure indicated on the pressure indicator located on the upper part of the column To let R 134a flow into the system open the valve at the recharging cylinder s base The total amount of refrigerant should not be installed in one session as it could block the compressor Install 20 30 grams at a time and close the val
