Proper alignment of doors will prevent excessive gas escape and ensure door sensor alignment. Some leakage, however, is normal. Because cabinets operate under varying degrees of positive pressure, Terra door gaskets are designed to allow controlled gas escape.
All cabinets are checked prior to packaging to ensure proper door alignment. However, they can come out of alignment during shipping due to the inherent flexibility of plastic.
Doors feature sensor magnets that must be aligned with the associated sensor on the desiccator door. If these magnets are misaligned, the Dual Purge™ system may not function properly, and door seals may not seat properly, allowing nitrogen leakage.
