Fastening Rooftop Unit Panel Tabs

As a business tech, I’ve labored on many fashions and varieties of rooftop gear.  One main drawback I’ve seen over time is panels not staying put, generally it is the fault of the tech forgetting to lock the screws.  Generally it is on account of stripped screws that go unnoticed and over time, vibration can push the panel out.  Some fashions of York rooftop items make the most of tabs fixed to the unit chasis with 7/16″ bolts.  Up to now, I’ve left these unfastened.  Today, I tighten them down on each unit after putting in the panel.  It can stop these calls the place the panel is discovered laying on the roof.  One other vital motive to lock these tabs is to keep away from water infiltration.  I just lately responded to a name the place the entire blower part was stuffed with water.  It rained closely the night time earlier than and the panel was barely bowed out, inflicting the panel to not seat correctly with the gasket.  The suction of the fan pulled within the water flowing down the unit exterior inflicting it to construct up contained in the blower part and leak into the constructing. Tightening down the tab, compelled the panel again into place creating the right seal.  If any unit, not simply York, makes use of auxillary tabs of any type, I extremely advocate placing them into use.  That being mentioned, guarantee all panels on all items are safe earlier than heading down the ladder.
