the superheat is set on all my cases. my fans are off during defrost and during my drip time.
my drains are all trapped, and they go to the floor drains set up beneath the cases. i have had an issue with the drains but hussman told me thats just because of the plastic they used being too brittle.
its possible im introducing air and moisture from the drain. maybe if i prime the main drains and check the vents becaause i could be getting air from the drains into the cases. i never really looked into that because my trough itself is not freezing up.
But we take care of a lot of the same store and all the drains are set the same but this store is the only issue and its refurbished cases.
im not farmiliar with the KE2 but im not sure it can be used with the einstein E2. my control doesnt seem to be the issue i have a ton of features off my einstein.
