Installation of Evaporator (Flow Down Matrix)

Installation of Evaporator (Flow Down Matrix)
 Date: 4.14.18
Location: Logan HS
Time: 2 hours
Goal: Install the flow down matrix in the 8" PVC Tee and tap out holes for cutoff valves.

The first thing that needed to be done was to drill and tap out the holes where the valves would be placed. We again used plastic fitting with a threaded nipple that would turn into the valve. A simple way to do this was to just drill a hole and silicone it the valve in. We try to stress the importance of craftsmanship so we drilled and then tapped the hole so the threaded nipple would easily thread into the PVC end cap and then enough threads were exposed on the other side to thread on the valve. It takes longer to do, but it will be stronger and more reliable.

The next step was to install the flow down matrix. Measurements were taken and two 1/4" aluminum rods were cut and installed into the holes that were drilled in the evaporator tank. This will provide a very good support structure so the flow down matrix can't drop down, yet still allowing for a nice water flow.

Holes were then measured and drilled into the PVC pipe for the inlet and outlet hoses. This went well although consideration had to be made for the location of the fernco and where the salt water sprinkler head would be located.

Our next goal will be to install the pump and get the evaporator side working. We will also work on a vibration solution for the condenser side.

All three end caps done.

Notice the aluminum rod to the right. This is being measured before cutting.

Both aluminum rods in place to support the flow down matrix.

Flow down matrix installed except for upper hose.

Holes are cut for the inlet and outlet hoses. We are ready to hook it up to a pump and reservoir.
