The labels for the high pressure and low pressure manifold and coupler valves may have been swapped, incorrectly stating which way to open or close the valves.
This may result in the release of pressurized refrigerant, posing a risk of injury.
What to do
Harbor Freight will notify owners, and send new replacement labels with instructions how to correctly apply them over the original labels.
The manufacturer has not yet provided a schedule for recall notification.
