In respect to this, how do you pierce r134a can?
Thread the R134a can tap onto the R134a can. Attach a R134a changing hose. Always add refrigerant to low side of A/C system. Turn the handle on the R134a can tap clockwise until the piercing stem pierces the R134a can.
One may also ask, how does a piercing valve work? Saddle valves are self-tapping devices. Once mounted on a line, with the included rubber seal in place, all that is required is to turn the valve clockwise until it pierces the water line. When the valve handle can no longer be turned, it is done tapping the pipe. Turning the handle counter-clockwise opens the valve.
Similarly, it is asked, where is the low side on a refrigerator compressor?
How to Find the Suction Side of Refrigerator Compressor
- Find the condenser on the refrigerator. The condenser is a coil or zig-zag-shaped piece of copper tubing that runs along the back of the refrigerator.
- Trace the condenser coil back to the compressor unit.
- Find the remaining valve on the compressor unit; this valve is normally right next to the output valve.
What should the low side pressure be in a r134a refrigerator?
For the normal running pressure in an R134A system, the coil should run at 22 pounds per square inch at the lowest temperature, 45−20 = 25 degrees Fahrenheit. Similarly, at the highest temperature, 60−20 = 40 degrees Fahrenheit, the coil should run at 57 psi.

What is a saddle valve on a water line?
A saddle valve is a valve used to supply liquid where a low volume, low pressure stream is required. The name is derived from the fact that it is mounted in such a way that it "saddles" the line, mounting it from both sides.
