This section containsA bottle of Wei Chang refrigerantplusA DIY automobile air filling pipe

Wei Chang is the United States imported R134a shipped to Kunshan Dianshan Lake filling (United States owned), the effect of package

With this set of products, you can automatically operate for automotive air conditioning refrigerant filling

Within the mainland except Hainan, Xinjiang, Tibet, Inner Mongolia, Qinghai and other regions three bottles of national shipping

The United States Wei Chang refrigerant three bottles of shipping:

 

Detection of cotton oil:

The company took pictures are not really making a map, picture, occasionally find a friend to help add a few words to steal.

The following is a case of Wei Chang Li, quality inspection report included, with the official seal and Huachang company telephone number above, can query

 

After June 5, 2014 to replace the new surface

The following is the quality inspection report and the original proof, can call

 

 

 

 

Simple operation, simple to give a tire gas:

Automotive air conditioning in general will each year about 10% of the loss of normal refrigerant, which is due to automobile air conditioning compressor sealing mode decision (automotive air conditioning compressor is half sealed). As long as we regularly to automotive air conditioning refrigerant can be added to detect. Don't need to worry about the use of methods, I tell you you friends DIY automotive air conditioning detection method. Friends can try it yourself with refrigerant.
The method is as follows:
1. need to prepare a car air conditioning DIY detection tube.
With R134A refrigerant 2. a bottle of car.
3. now to the car testing pressure: first DIY tube opener end of the thimble anti clockwise rotation to the top of the bottle opener, the refrigerant is screwed into the screw.
4. identify the low voltage interface in general under the hood of the left side has a blue or black hat, hat there is a L word, the small cap is screwed down.
5. will the car engine starting and open air blower AC switch, open to the maximum, run and wait for three minutes. The DIY pipe interface to access low end car air conditioning.
6.DIY interface connected to the low pressure pipe, DIY pipe pressure gauge will instantly have dial indicator. Then the DIY tube on the pressure gauge is consistent with the pressure of air conditioning system, see the pressure on the pressure gauge calibration system, know the pressure. The need to add refrigerant in how much pressure? Then there is a description of knowledge! Automotive air conditioning system pressure varies according to changes in the external environment temperature.
The ambient temperature (Fahrenheit) low pressure gauge pressure, numerical table below pressure is constant temperature in the laboratory in the theory of value, the outdoor temperature in the process of using is not up to the requirements. So the owners of friends please press chart in numerical minimum calculation in the use process, calculation method is the minimum value to the minimum value minus 10PSI calculation is normal pressure system, the pressure must not exceed the minimum pressure, more than once, the opportunity to reduce automatic protection, then it will be very poor cooling effect! Such as the outside temperature of 30 degrees, the chart shows 45PSI-55PSI, which is a constant value. We should use the calculation of 45PSI minus 10PSI pressure, the result is 35PSI, this is the normal pressure, preferably not more than this value.
18.33 degrees Fahrenheit 65 corresponding to the system pressure is 25-35PSI
21.11 degrees Fahrenheit 70 corresponding to the system pressure is 35-40PSI
23.89 degrees Fahrenheit 75 corresponding to the system pressure is 35-40PSI
26.67 degrees Fahrenheit 80 corresponding to the system pressure is 40-50PSI
29.44 degrees Fahrenheit 85 corresponding to the system pressure is 45-55PSI
32.22 degrees Fahrenheit 90 corresponding to the system pressure is 45-55PSI
35 degrees Fahrenheit 95 corresponding to the system pressure is 50-55PSI
37.78 degrees Fahrenheit 100 corresponding to the system pressure is 50-55PSI
40.56 degrees Fahrenheit 105 corresponding to the system pressure is 50-55PSI
43.33 degrees Fahrenheit 110 corresponding to the system pressure is 50-55PSI
7. low pressure air conditioning system, the need to add refrigerant, the bottle opener in the thimble clockwise, pierce the refrigerant bottle, bottle opener in the thimble immediately counter clockwise to the top, (Note: this time scale pressure gauge will show to 100PSI to 110PSI, 2 seconds after the time scale pressure gauge will slowly drop down, scale back the original show, this is normal, because the bottle is punctured, the pressure, a few seconds it shows the R134A bottle of the pressure in the bottle pressure by the compressor after absorption is shown as the pressure in the system!) Shake the refrigerant bottle, the refrigerant gas will flow into the system at the same time, see the pressure gauge, and the temperature and pressure of PSI units to be. Note: the refrigerant bottles do not inverted!!! (except oil mixture)
Note: in the absence of pierce the refrigerant bottle, DIY tube has a little air, if the owner to need to drain a little air in the pipe, please according to the following method, in the absence of refrigerant bottles will pierce the refrigerant bottle opener and gently loosen a bit, then the DIY pipe in the air will be air conditioning system in the refrigerant to go out, then tighten the refrigerant bottle!!!
8. observed pressure gauge is normal, please immediately opener in a clockwise rotation to the lower end of the thimble and screw, remove the air conditioning system of low port connection. Like a bottle after adding enough, please add second bottles of refrigerant on the narrative method, until the outside temperature and system pressure to date.
9. the car of refrigerant air conditioning system to complete, please L small cap screw.
Note: the above pressure scale and filling method is filling in refrigerant Sales USA ID and EF, completed a successful filling of my own, and will feel tire gas as convenient!

Please note: when the outdoor temperature is 20 degrees of filling!
