Xuzhou Sheng Erda Refrigeration Electrical Services Limited II. When installed there to open the valve emptying: as follows: After the inside and outside of Xuzhou fixed installation used wedding dresses, 1. Air conditioning is good, mainly to connect the inner and outer tubes are tight Xuzhou good hand air conditioning recovery, attention must connected, to prevent refrigerant leaks. 2. Allen hit the autopilot switch on the air conditioning to work to open the high-pressure valve (thin tube valve) Xuzhou air conditioning maintenance and fluoride, fluoride in the mouth with a hex withstand thimble (fluoride mouth on the low pressure), so that the inside of the gas came out, about 10 seconds you can, do not wait too long, so refrigerant running too much. So you can make the air inside the pipe to put out. 4. Then the high and low pressure valves are open, both inside and outside the machine's power cord is connected to it. Note: The connecting pipe is copper, not the disk into a dead corner, otherwise it will affect the flow of refrigerant can cause cooling and heating. Demolition when the first harvest of fluorine, otherwise it will cause leakage of fluorine. Xuzhou 圣尔达 Refrigeration Electrical Services Ltd removable air moving machine we call the moves first need to recycle the refrigerant air conditioning refrigerant recovery which it needs to be recycled in the winter is not cooling refrigeration state how to do? Touch the machine with warm water temperature sensor allows the operation of the machine as well as the four-way valve line can be pulled when the first thin tube cooling valve shut and then wait for about 1 minute or so off the crude pipe valve, be sure to remember compression machine running when it is valid. , Then recovered after a good excuse to put the machine into the gray bag up there do not have to wrap the brass connector. Then begin outside the machine power cord or something, just great since you can then install it demolished almost put the machine after a good position to determine when to wear out from the air holes and then determine that you are outside the machine and then hang on and dismantle the equipment is to row about the air that there are two ways I teach you in the most primitive of the first thin tube is thick tube connected well after tightening the valve to open a little thin tube beneath the thick tube that the downward A total of a turn on top of it with something when refrigerant excluded again when tightening thick tube wiring can then test machine Xuzhou Hitachi central air conditioning repair center, air conditioning repair, Sheng Erda refrigeration refrigeration appliances from Xuzhou Sheng Erda Services Limited.
