Air-conditioner installation need to know what

freezers - price Air-conditioner installation need to understand what the above chapter, has told you what needs to be done to prepare before move freezers, so move, freezers will need to reinstall, then what should we do this time? What need to prepare? Let the cooler price to share some knowledge in this field. First is to install: freezers in the installation of a new position, please see the line and the random manual for connection circuit system, this is the same as new installation. However, due to the erection and dismantling of the bell on the brass can deformation or damage in the process, some pressure to shoulder wall thinning, even cracks, check carefully before installation. If found damaged or suspicious place, must enlarge bell mouth again. Then is to supplement of air-conditioner refrigerant, add refrigerant used low voltage side gas filling method is more convenient and safe. Put the refrigerant steel cylinder shaft, export facing up. Unscrewing the trachea outdoor nut, the 3-way valve repair at the mouth of the hose will repair the mouth and the cylinder outlet connection. Slightly open the cylinder valve first, with the flow of refrigerant to the best of the air inside the hose, then start of air-conditioner under refrigerating condition, compressor operation, open the 3-way valve repair valve mouth, then slowly open the cylinder valve. At this time, the flow of refrigerant gas from the rough pipe to the compressor suction mouth _, enter into the system. Finally, matters needing attention: ( 1) Cant be reprocessed trumpet smooth and symmetry, no wounds, no burr, there shall be no cracks, so as to guarantee the reliable sealing connection of pipeline system. ( 2) Refrigerant deficiency and excess, will affect the cooling effect, even to a bad compressor. The extension pipe of air-conditioner, should be adding the right amount of refrigerant in a timely manner. ( 3) When vacuum pump leakage, should pay attention to the sealing connection parts, prevent caused by mixes up the phenomenon of miscalculation caused by vacuum degree is not enough. And when the stress reaches 133. 3 pa, should shut three-way valve valve, and then disconnect the vacuum pump power, prevent the reverse flow of air, the wrong result. ( 4) High-rise resident moving, must have enough people, usually requires four people cooperate with operation.
