F6-BOOST REFRIGERANT STORAGE CYLINDER SAFETY

Check with your federal and/or state regulations on the proper vessel to store refrigerant. In the USA, DOT
CFR 40 is required when filling and transporting refrigerant storage vessels.
This unit is designed to be used with 400 PSIG rated storage vessels. In the USA, this is denoted by a DOT
rating of 4ABA400 or 4BW400.
When recovering or filling a refrigerant storage vessel, never fill beyond 80% of its water capacity (WC).
Filling a tank at 70F to 90% and then putting it in a hot service van will cause the liquid to expand until it
becomes 100% full. The hydrostatic force of the refrigerant could rupture the tank causing rapid venting or
explosion. See illustration in Diagram 1 below.
To calculate the maximum weight of a storage tank you will need to get two ratings from the tank. One is WC
(water capacity) and the other is TW (empty tank weight). The maximum tank weight (MTW) is calculated as
follows:
MTW=.8 x WC + TW
Turn on the scale and tare to Zero. Place storage tank on scale. Read the weight. Compare that to the MTW
calculated above. If the scale weight is below MTW, the difference is the amount of storage capacity you have
in the tank. If the scale weight is above MTW, you have a tank that is overfilled.
If an overfill condition does exist on a storage tank, place in a cool area and transfer some of the refrigerant
into another storage tank until the weight is below MTW.
Always use a calibrated scale to monitor the total weight of the tank when recovering or filling refrigerant into
a storage tank. Devices such as tank overfill floats should stop the recovery unit, but do not stop the flow of
refrigerant to the storage tank.
If the scale or an overfill device does detect tank full condition, the recovery unit should be turned off and the
storage tank valves closed.
