To prevent overfilling, recovery cylinders should not be filled to more than 80 percent of their internal volume. hbbd```b``A$ I would of thought it wouldn't of really allowed for refrigerant density, the R134A would actually end up filled above 80% liquid level if you just went off WC. Cylinder fill = WC (kg) x relative density x 0.8For R410A being recovered into a cylinder stamped with a WC of 65kg:Cylinder fill = 65 x 1.06 x 0.8 = 55.12 kg.

And then says you can calculate based on density, but the 80% WC rule of thumb will allow for all different refrigerant densities. %%EOF Well yeah obviously because you would probably reach 100% liquid level before you got to that weight. This maximum weight will vary slightly as different refrigerants are used in recovery cylinders and different refrigerants have different liquid densities.

Any cylinder showing signs of rust, damage or heat must be reduced to 0 psig by recovering the contents to another cylinder and then the tank can be discarded.

Next, the digital scale must be turned on and zeroed. Find the amount of refrigerant in the unit by checking the units faceplate (B). To determine the total weight of the bottle with refrigerant inside, multiply .8 by the WC. As refrigerant is being added to a recovery tank, it increases the pressure in the tank and causes the tank to naturally heat up; increasing recovery time. The 80% of marked water capacity rule of thumb is to preserve the room for expansion when the cylinder is stored in different temperatures when filled to this amount. So w.c. 26.6 X 80% = 21.28lbs of refrigerant right? De"jn`K``v=^fUAF4XXV\Q`-@d|`>Iv %`2Dud T |H8]|F Cylinders must remain in good, secure condition. You must calculate to make sure the recovery tank will safely accept the amount of refrigerant being added: (Note: if the tank is empty, the scale should match the tare weight stamped onto the side of the cylinder.).

To me that all sounds good and well if you were filling it with water, but am I right in saying liquid refridgerant weighs less than water (in our case R134A), so therefor to put 22L of R134A in would fill the liquid level to 100%, although it would weigh less than 22kg.
