This product notice is to inform you about an improvement we have made to the spring assembly on the Gen II Side Mount Liquid Level Controller.
Beginning 11/1/2018, all Gen II side mounts with 6”, 12”, or 18” extensions will include a 5557A, which contains both a 5557 spring and a 5467 spring. This will allow for a tighter span, especially when operating in 2-phase applications.
This change is immediate and will be seen in all future Gen II side mount orders. You do not need to change out current springs, and it requires no further action.
Please note that all other side mounts (without extensions) will include only a 5467 spring, regardless of displacer size or material.
