Remove the existing front cover of the metal sheet box to expose an opening. Place the fan over the opening to determine its best fit. Cut off any unwanted sheet metal using the dremel tool. Drill holes onto the metal sheet and use metal screws to fix the fan firmly onto the metal box. Hook it up to blow in the direction you want.
Leave the cover of the sheet box intact. This ensures that you will fit the fan back into the cover. Mount the sheet box with the fan onto the main house. Use the metal screws to perform this procedure.
Place the bilge pump in water alongside an existing Alternating Current (AC) pump. Disconnect the hose pipe from the existing AC pump and connect it onto the bilge pump. Mount two rocker switches to the cover of the sheet box. Place the rocker switches on the opposite side of any existing switches. Drill holes on the plastic and connect the bilge pump to the fan.
Cut the MC connectors on the solar panel to connect the wire. Use crimped wire connectors to both terminals of the wire and also on the fan, pump wires and the switches. Place the solar panel directly on the roof and run the wires over the eave of the roof. Place the exposed wire in flex tubing, which acts as an enhanced insulator.
Run the positive terminal to the two rocker switches that control the fan and the switch. The negative terminal goes to a common ground and then proceeds to the fan and pump. Pass the wires through an opening in the cooler and through a window where the existing wires run. Connect these to the switches and back to the two devices.
