I placed two NEMA L5-20P to 5-15/20R Extension Cords on the "dirty" power outlets and placed 3 Heavy Duty Power Strips in B111B Mobile Clean Rooms. My idea is these "beefy" power strips indicate they're for things that don't need clean power, like pumps. I haven't hooked up the pumps to them yet as they're in use, except the LFC Scroll Pump which was and is turned off. See attached photos for their locations: the Northeast corner of the clean rooms, underneath the insersection of the optics tables, and on the top shelf.
After Alex turned off the pumps and fully vented the SNSPD Dewer, I disconnected the pumps and connected them to the heavy duty power strip. I removed the NEMA L5-20 Extension cord that was previously used that didn't reach to the ground and put it away on the south shelves with the other cords.
