Hopefully this will be an easy set of questions to answer.
1) When did Belimo begin inserting a small, metal pin in the shaft of the of their LRB replacements? I spent a disturbing amount of time trying to figure out WHY the new actuator would not fit on the valve body only to discover a small, metal pin jammed in one corner of the actuator shaft. It slides out easy enough, but you need to know the danged thing is in there first in order to remove it.
2) There is nothing in the documentation coming with the new actuator to indicate the pin is in there or that it is required to be removed prior to using the device. Does anyone know WHY the pin is in there, other than to generate business for the pharmaceutical industry making blood pressure medicine?
The building engineer thought I would have known about it and apologized for not sharing the news. He and another tech had to call the supplier to figure out what the heck the problem was and how to get the new actuators to fit.
Thanks for any logical, reasonable, should-be-obvious kind of answers.
