Not all refrigerators have gas circulating that is safe to change at home. Before refueling, be sure to check which refrigerant is the engine of your refrigerator and then decide what you will do. You may need to call a specialist, because replacing it at home will be extremely dangerous.
- when changing the gas supply, be sure to disconnect the refrigerator from the power supply.;
- when you start working, you need to ground the equipment;
- ventilate the room every 15 minutes during refrigerant injection or discharge;
- do not turn on electrical appliances and do not smoke;
- please read the safety instructions for fridges when working with freon before you start working.
Take a gas station and connect its left branch pipe to the shredder valve, connect the middle branch pipe to the refrigerant cylinder, and attach the right one to the vacuum pump. Take care and check in advance, all the valves on the cylinder and the station must be closed. Pump out the air.
Open the taps at the gas station and turn on the pump so that the pressure drops to min. mark. The process is quite long (from 15 to 30 minutes).
Close the right-hand valve, open the valve on the fuel tank, and fill the refrigerant to the volume required for your model of cooling system. Turn off the valve.
Now turn on the refrigerator and check the pressure quality in the unit. Is everything working? Now make a pinch of the compressor pipe and seal its ends.
Take the leak detector and check again that the installed system is working properly.
