Another hot humid weekend. They called for occasional showers, so I rigged up some tarps for protection...this is not my permanent cover ;-)  Got the primer on the rest of the frame and cut in the holes for the ducts.  Finally threw out my damn Crapsman saber saw after trying to cut with it.  I have had it for years and it has alway cut crooked and breaks blades constantly.  Finished the holes with a B&D saw I bought at a yard sale for $5 a couple years ago. I need some dry weather before I caulk and attached the duct collars later this week.

So,while I was waiting for the weather to clear up some, I decided to work on the mechanicals.  Mounted my fan housing on the window sill.  The sharp techies out there will probably recognize my housing as a Dell Laser Printer.  I used the case, power cord, switch and circuit breaker.  Waiting for my transformer and relay switches for the snap switches so I can run 24 volts to the snap switches out in the box.  I am planning to install the snap switch right above the outlet from the back, sticking the switch face into and 1 inch hole in the plywood back and iso.  The sensor part of the snap switch would actually be recessed in the iso.  I have some doubts about this setup, but want to be able to easily remove the 110/90 switch with maybe a 80/65 that I have if I experience low temps.  This basement room has typically been in the mid 50's in the winter time...one reason I am doing this project.

That's awesome. I love repurposing but I guarantee that is a mod I never would have thought of.

Bruce-

I'm so glad you primed your foil surface before painting. There are plenty of examples of bubbled or flaking black paint from people that skipped the primer. Not always, but for something where the paint can get damp from condensation and hotter temps than paint is normally exposed to, it should help the paint to adhere better. And who wants to open up a collector just to repaint a surface. 

So how often do you expect to replace the color cartridges? Nice adaptation of something that would have ended up in the trash heap! Is there any way to add an air filter, or will the filter be elsewhere? And if possible, add a bypass switch so you can turn the fan on manually. I've found a bypass switch to be quite useful at times, such as working on the ductwork, and making any adjustments to the snap switch wiring while still allowing air to flow, etc.

I might be wrong but I think painting a reflective surface defeats the purpose. I always put the reflective surface towards the outside.

Probably reflective on both sides. I have the same stuff and mine is.

Yes, The RMax iso is foiled on both sides and I believe priming them (and everything else) will save a lot of problems in the future.  I do plan to get a 7 1/2 inch by 11 1/12 inch filter in the area in front of the fan that used to be occupied by thermal laser jets.  I have room to work there for whatever filter(s) I can find cheaply, as this is a high dust area in my 75 year old house.  A bypass switch is a good idea...I need to draft up a schematic and see where I have room for it in the rear area (electronics) of my printer...err fan housing.  I am also optimistic enough that I ordered a second relay switch for a fan on the output side...but we will wait to see what kinds of performance we get out of my contraption. The transformer and one relay switch was shipped from supplyhouse.com (thanks, Don for that tip) so I should get it tomorrow.

The polyiso I have is a different brand I think and is only foiled on one side. The other side is just papered.
