Speedsetter 300 Vastech Developer Drips

We are producing poly plates on a SPEEDSETTER 300 with a Vastech Processing Unit and now and again there are drips showing on our plates. We thought it was a light leak but were informed it is probably the processor's developer tank stainless steel cover condensation sweating and dripping on the top of the plate. Upon inspection we believe this to be true. Is this normal? Is the developer set to warm? Can this be avoided without having to wipe the equipment down each time we use it? Thank you for any input.
