BOMBA DE CALOR ASTRAL - Ferromar

ENGLISH8.- Once in a while, close the LO valve of the gauges in order to confirm the real pressureof intake.9.- Verify that the outflow pressure is not above the normal range for normal workingconditions.10.- When the correct weight of refrigerant has been charged, close the LO valve.11.- When the equipment is functioning according to the specified working conditions,close the valve of the charging bottle and disconnect the tubes taking precautions regarding gaspurge.12.- Place the caps on the supply and return lines of the compressor.Detecting Leaks:Leaks may appear due to various reasons. Leakage risk may be greatly reduced if theequipment is correctly installed by qualified personnel and by taking certain precautions in theassembly of the equipment.The following points are especially important:* Good welding technique.* Use of antivibration tools.* Use of top-quality components and tools designed specifically for the pressure andtemperature conditions of the equipment.Symptoms of a leakLeaks will cause a decrease in the refrigerant charge in the equipment. Low refrigerantcharge may be the cause of:◙◙◙◙The temperature of the evaporating unit is too low. This may be caused by anobstructed fluid line or the incorrect operation of a capillary. The consequences may bevery serious, for example ice may form on evaporating unit, etc.The compressor is functioning on cycles which are too short. This may also be due toincorrect functioning of control humidistat.Compressor is overheated: low gas charge makes for insufficient flow of vapours tocool the compressor. This may cause the tripping of the internal thermal indicator of thecompressor.The compressor operates continuously, there is not enough refrigerant to obtain thedesired results, and since the specified temperatures are not reached, the equipmentdoes not shut down.In any case, it is better not to wait until a leak appears, and for this reason, it isrecommended that the equipment be serviced regularly.Methods for Searching for a Gas Leak:There are various tools on the market used in order to detect leaks, although not all of themare sufficiently sensitive to certain types of refrigerants. It is very important to choose an adequatedetector for the refrigerant used for this equipment and that the maintenance guidelines byfollowed.44
