Step 13The Ventilation System
Start the Ventilation system by getting:
4ea, 5" ABS Deck Drains
1ea, 4" PVC Tee
2ea, 12V Computer Cooling fans
1ea, Shop Vac Air Filter
4ea, 3 1/2" X 1/4-20 Bolts & Nuts
3/4" X 6" X 12" Pine Board
2ea, 4" Metal Foil Dryer Exhaust Vent Tubes - Needs To be 10" Long Each Minimum
Follow the picture sequence to show the assembly procedure when in doubt. Start with the 4 square floor drains, you will need to cut out the inner grate sections, these are only to allow for a framework to hold the cooling fans.
Mount two hollowed out grates between each cooling fan and hold together with clamps while you drill out the corners to allow for the bolt placement. Attach the bolts as shown.
Turn on the fans to be sure which way the flow of air is going, this is important as you will have to be sure the air is flowing INTO THE DOME and SUCKING AIR THROUGH THE FILTER.
RTV the Fan assembly into the tee so the flow of air will be going OUT of the TEE.
After the RTV Dries overnight, insert the 4" Round Deck Drain into the Shop Vac Air Filter, and glue up into the filter about 1/2".
Inser the remaining white drain into the top of the PVC Tee, use lots of white RTV Glue to hold this in place, let dry overnight.
Make the cap for the filter by cutting out two discs from some white pine, each disc should be 4" & 5" in diameter, router off one edge of each disc and place together and clamp with a small ammount of glue in between the discs. Drill a 1/4" hole through the center and mount a wooden knob handle.
Attach the 4" metal dryer vent lines to the air pump, Cut two holes 5" in diameter through the approximate center of two of the Half Pentagon base walls and mount the two Dryer Vent Covers as shown in the pictures.
Attach the dryer vent lines to the Vents on the dome walls, connect the electrical lines to a 12V power source, (12V Transformer connected to 115V Wall Socket)
Power up the Air Conditioner and get inside!!!!!!!!
