WARNING
Refrigerant Storage Container Safety
What Can Happen: Refrigerant storage containers may vent or explode when the working pressure of the container is exceeded.
How To Prevent It: Refrigerant storage containers are designed with different working pressures. Verify that the rating of the storage cylinder is appropriate for the refrigerant being recovered.
For R-410A, 4BA400 and 4BW400 are appropriate ratings for refrigerant storage containers.
What Can Happen: “80% Shut Off Switches,” also known as Tank Overfill Sensors and Overfill Protection Devices, may fail to prevent overfilling of the storage cylinder leading to venting or explosion.
These sensors only cut power to the recovery machine, and do not stop the flow of refrigerant, which may continue due to a siphon, or due to temperature-induced migration.
How To Prevent It: Do not rely on these switches to prevent overfilling. Only a refrigerant scale can provide an active and accurate measurement of the amount of refrigerant in the storage container.
Do not rely on these switches to stop the flow of refrigerant into the container. Only the valves on the recovery machine and on the cylinder can stop the flow of refrigerant into the container.
What Can Happen: Refrigerant expands when heated (Diagram 1), and storage containers may vent or explode when filled over 80% capacity.
How To Prevent It: A refrigerant scale must be used to monitor the amount of refrigerant in the storage container.
Be sure to close the valves on the storage container when it has reached 80% capacity.
Diagram 1:
Diagram 1: Overfilled storage containers may explode due to liquid refrigerant expanding when heated.
Transportation of refrigerant storage cylinders more than 80% full is a DOT violation.

Refrigerant Recovery Tips
Accounting for Hose Weight
The weight of recovery hoses should be taken into consideration during recovery and charging. Be sure to `tare’ the scale only after placing the cylinder on the platform and connecting hoses (to both tank and system). Also make note of the weight if hoses are removed at any point during the process.
Purging Non-Condensables from Recovery Cylinders
In the event that the Recovery Cylinder pressure is higher than expected, or if the recovery process seems slower than usual, use an external gauge (not the gauge on the recovery machine) and a Refrigerant Pressure/Temperature chart to check for the presence of non-condensable gases in the cylinder.
You can bleed/purge non-condensables into another cylinder following this procedure:
- The recovery cylinder must remain undisturbed for at least 24 hours for the non-condensables to rise to the top of the cylinder.
- Connect the recovery cylinder Vapor Port to the Vapor Port of an empty second recovery cylinder with a short 1/4 in. hose.
- Consult a Refrigerant Pressure/Temperature chart, and check the temperature of the recovery cylinder to determine what the pressure should be.
- While the pressure is higher than the pressure on the chart, slowly open the Vapor Port to bleed off excess pressure until it is about 5 psi (0.35 kg/cm²) above the pressure listed on the chart.
- Close the valves and let the cylinder stand still for 10 minutes. Repeat if necessary.
80% Fill Weight
Refrigerant recovery cylinders should only be filled to 80% of their maximum volume to allow for expansion during transportation. Recovery cylinder weight capacity is calculated by the manufacturer using water and given as Water Capacity. Since refrigerant has a different density than water you must make a quick calculation to determine the maximum weight of refrigerant you can recover.
| Refrigerant | Liquid Density @ 130ºF (Lb/Ft3) |
Fill Multiplier |
| Water | 61.522 | – |
| R-22 | 66.312 | 1.08 |
| R-134a | 67.46 | 1.1 |
| R-404A | 53.18 | 0.86 |
| R-407C | 62.28 | 1.01 |
| R-410A | 56.11 | 0.91 |
| R-417A | 62.383 | 1.01 |
| R-417C | 65.243 | 1.06 |
| R-422A | 58.343 | 0.95 |
| R-422B | 61.85 | 1.01 |
| R-422C | 59.174 | 0.96 |
| R-422D | 60.642 | 0.99 |
| R-437A | 65.231 | 1.06 |
| R-438A | 61.804 | 1 |
| R-454B | 51.83 | 0.84 |
✪ See Page 6 for additional information
Stamped markings on the recovery tank indicate Tare Weight (TW) and Water Capacity (WC). The following equation should be used to calculate the maximum weight allowed in a cylinder.
WC x Fill Multiplier x 0.8 + TW = Max Total Tank Weight
Example (R-22): WC is 47.6 lbs, TW is 24 lbs.
47.6 x 1.08 x 0.8 + 24 = 65.1 lbs Total Tank Weight (41.1 lbs of R-22)
Preparing a Cylinder for Recovery: Prior to beginning recovery, the cylinder should always be evacuated with a vacuum pump. A deep vacuum of 500 microns or better is recommended as this eliminates the possibility of non-condensables as well as improves the initial refrigerant transfer. Always verify with a digital vacuum gauge to ensure you have hit the target. New recovery cylinders may not be sufficiently evacuated – always verify before use.
Preparing for Fast Refrigerant Recovery
Every recovery procedure starts with the same four basics:
- Remove any access valve cores from the AC/R System access fittings with a Valve Core Removal Tool. This removes restrictions that would otherwise limit the performance of the recovery machine and/or cause overheating of the recovery cylinder.
- Remove any core depressors from the hose fittings. Do not use “quick disconnect” or “auto-shutoff” hose connections for refrigerant recovery, as this can bring the recovery to a halt. Use only ball valves for low-loss.
- Use the shortest length of 3/8 in. diameter hoses possible on every connection. Even with 1/4 in. fittings, the larger hose diameter can deliver better performance during recovery.
- Purge the hoses of non-condensables as you connect them, as needed, using best practices to minimize any refrigerant release (aka “de minimis”). Excess non-condensables can cause tank overheating, and may contaminate recovered refrigerant.
✪ Tip: Consult the manufacturer of your Refrigerant Recovery Machine for setup guidance.

Additional Equipment Considerations: Refrigerant recovery requires–and can often benefit from specific use of–additional equipment that connects the recovery machine to the system and recovery cylinder. Verify operational details and safety information from the manufacturers of other equipment before use.
- WARNING A leaking hose may cause venting of refrigerant, and may introduce atmospheric air or other contaminants into the recovered refrigerant. Examine the gaskets on each hose to ensure they are intact, checking for any damage or wear that may lead to leaks.
- Valve Core Removal Tools with a ball valve (such as the Appion Valve Core Removal Tool) can be used as high flow low-loss fittings, in addition to the main function of removing valve cores.
- The recovery cylinder should have extra capacity beyond the amount you intend to recover.
- Examine your external manifold gauges (if used) for proper valve operation and calibration of the gauges. Contact the manifold gauge manufacturer for instructions in this process.
Note: Appion does not recommend the use of a manifold gauge set on most systems due to restriction of flow & refrigerant loss. - Use a new inline filter drier when pumping dirty refrigerant. Replace the filter drier after each use. If the filter has exceeded its capacity, this may affect the performance of the recovery machine.
- Use a sight glass to verify liquid flow. This can also be useful for troubleshooting purposes. Make sure that the sight glass is in good condition and does not leak.
General Maintenance and Care
The WS130 is a precision instrument that must be maintained to ensure proper function. Please follow the guidelines listed.
- Store the WS130 in a cool, dry environment when not in use. The recommended storage temperature (without batteries) is -4 °F to 140 °F (-20 °C to 60 °C).
- Inspect the platform before use to ensure no objects or materials are obstructing the platform from free movement while in use.
- Never use the scale in the case. The case is for protection and may prevent the platform from free movement.
- Remove batteries before storing the device for long periods of time.
