Step 6: Spiral deployment and finishing touches
Once the work was completed we carefully migrated the beast to the roof. We setup on the south facing side of the house. We fastened a rope to the center of the frame and tied it off on the north side of the house to prevent the coil from sliding down the roof. Once it was secured we connected the garden hose adapters to each of the leads coming from the coil and hooked up the cold water feed and hot water return hoses to the coil. (Note: Both our connector where female so we ran the return hose backward with the female end in the spa.) After the hoses were connected we hooked the cold water feed hose up a regular garden hose faucet and charged the system so to speak using the house hold water pressure. Once the water was completely through the system we connected the cold water feed to a pump in the spa and ran it for a test drive. Voila! it worked the pump was pumping water through the coil and it was returning to the spa.
I will update this instructable with thermal findings once we get a full day to test the system.
