ARY MAINTENANCE the ANKs are filled with R410A gas and are inspected at the factory Under normal condi tions they do not require Technical Assistance related to control of refrigerant gas Through time gas leakage may be generated from the from the joints causing refrigerant to escape and discharge the circuit causing appliance malfunctioning In these cases the leakage points are to be discovered repaired and the Gas circuit is to be replenished respecting the December 28 1993 n 549 law 27 6 LOAD PROCEDURE The load procedure is the following Empty and dry the entire cooling circuit using a vacuum pump connected to the low and high pressure socket until 10 Pa is read on the vacuum meter Wait a few minutes and check that this value does not rise above 50 Pa Connect the refrigerant gas cylinder or a load cylinder the socket on the low pressure line Load the amount of refrigerant gas indi cated on the appliance features plate After a few hours of functioning check that the liquid indicator indicates the dry circuit dry green In the case of partial loss the circuit must be emptied com pletely before being re loaded R410A refrigerant must only be loaded in the liquid state Functioning conditions that are different to the nominal conditions can give rise to values that are greatly different The sealing test or the search for leaks must only be performed using R410A refrigerant gas

31. NOTE On the following page an example is given to help graph reading Using the diagram below it is possible to determine the percentage of glycol required this per centage can be calculated by taking of the following factors into consideration one Depending on which fluid is considered water or air the graph is interpreted by the right or left side at the crossing point on the curves with the external tempe rature line or the water produced line A point from which the vertical line will pass is obtained and this will distinguish both glycol percentage and relative correc tion coefficients 11 1 HOW TO INTERPRET GLYCOL CURVES The curves shown in the diagram summarise a signifi cant number of data each of which is represented by a specific curve In order to use these curves correctly it is first necessary to make some initial reflections 1 Ifyou wish to calculate the percentage of glycol on the basis of the external air temperature en ter from the left axis and on reaching the curve draw a vertical line which in turn will intercept all the other curves the points obtained from the upper curves represent the coefficients for the correction of the cooling capacity and input power the flow rates and the pressure drops remember that these coefficients must be multiplied by the nominal value of the size in question while the glycol percentage value recommended to produce desired water tempe rature is on the lower
