Example of the exposed bearings on the job siteThis should be modified to be more of a standard installation.This OA damper motor mount to the armature is incorrect and the damper has a lot of play in it. Common throughout the equipment room.This is one of eight Mixed Air Damper Motors that are acting up. Common on AHU S – 1 to S – 4. ALL should be corrected.All the Curtain style Fire Dampers have dropped on AHU S – 4. Difficult to get to and last reported that they are now open and waiting to restart the unit..Thank you Pete Coolie for all your hard work! It just shows what some UW people will do to get something done.Dropped Curtain DamperThe unit has such a high suction pressure that the condensing water from the Air Conditioning Coil overflows the Units internal pan that it needs to be captured before is spills out onto the floor and down into the Arts Museum.These is a “as found” steam trap body that was releasing excessive amounts of moisture into the 5th floor equipment room. It was immediately corrected by UW Steam Fitters and a BIG THANK YOU TO THEM FOR THAT. YOU ARE THE BEST ED CORCORAN!These pneumatic damper motors do NOT track correctly. Usually damper motors with pilot positioners are installed (correctly) and then the pilots are calibrated and all is good. Note the 3 inch strokes of these damper motors. Even though they share a common signal line, are not stroked even closely to the same lengths. This is a common mismatch issue and should be rectified; however, it is common on nearly all the units in the 5th floor penthouse, even the units with pilot positioners. Common problem in buildings with overall intermittent building pressure issues.Additional image of the previous one.This coil is at the end of it’s life-cycle. This coil is at the end of it’s life-cycle.E – 13. Loose Internal Insulation at the discharge of the unit.
